Professional Review of PowerStrider Olympic - Aluminum

This is Bacchanal Promotions' review of the new PowerStrider Olympic - Aluminum (CZ Series) stilts.

Our first impressions of the new stilts were positive, the most noticeable differences from our other stilts (Poweriser Advanced) were the weight and much more elegant design. Putting on the stilts for the first time, we were very happy with the quick-adjust cuff mechanism, however the plastic bindings were definitely a downside. Walking on them for the first time felt much more comfortable than our other stilts, not only because of the weight but also the streamlined design. The feeling that we might hit the foot-plates together was much less since a lot of the excess materials have been removed, including the stability rods on the side of the feet. We didn't experience any difficulty with the heel sliding out of place, although when our friends tried them on, some expressed difficulty at the lack of lateral support on the heel.

When we were able to test the stilts side-by-side with the Poweriser Advanced model, a number of things became shockingly clear. The difference in weight is extremely substantial. After wearing the CZ series, jumping on the Powerisers made it feel like there were weights attached to our feet. In addition to the weight the streamlined design made it much more comfortable, and the easily adjustable cuff made it simple for each user to customize them quickly for optimal comfort.

Heights: Perhaps the least obvious but most important difference between the two models was the height of the footplate. It seems as though the two-inch increase in standing height also gave the spring extra room to move, which allows for increased response from a softer spring. Though we are able to easily push our Poweriser 90-120 springs to their limit, the Powerstrider 70 springs seemed to have endless room to gain height. The soft PowerStrider 70 springs felt much softer while running and bouncing low, which made jogging and hopping comfortable and less stressful on our bodies. When jumping high, we originally thought we would bottom-out the soft springs immediately, but were pleasantly surprised when we discovered how difficult it was. It requires much more power to bottom-out the Powerstrider springs, and we seemed to also increase our maximum height by at least six-inches. We look forward to further testing to prove that we are actually jumping higher than we ever have before, but initial tests have been difficult due to winter weather conditions.

Our last test was indoors, which made yet another difference abundantly clear. There was almost no noise while walking or jogging on the Powerstriders, and while jumping high the noise was reduced by at least half from the other stilts. The only noise we heard was of the pad hitting the ground, which was of course louder depending on how high we went, but there was no noise from the parts shifting or rattling. This is one of the biggest selling points for us, as we use the stilts professionally, and particularly when we're doing shows indoors it can be quite distracting to have loud clanks while jumping.

The pair we are using has already experienced several hours of use in another test, so it is easier to spot possible durability issues than with a brand-new pair. We noticed of course that the hoofs will need replacing more often than the Powerisers', but since replacement hoofs will be about 1/3 of the cost and are much easier to replace, we find that this is still a better option than the Powerisers. We did notice a slight squeak in one of the stilts, not loud, and can likely be fixed by adding oil to one or both of the pivot points, but we feel it should be mentioned. Also, the top of the spring on ONE of the stilts has a very small amount of wiggle-room. This is nothing compared to the wiggle on each of the Poweriser joints, but we definitely hope this isn't the beginning of a larger issue.

Flipping and other acrobatic stunts are easier on the new models not only because of the weight difference but also the reduced bulk. The Olympics feel much smaller around the feet and legs, and seem to allow easier variation in leg positions.

Bottom Line:
The PowerStrider Olympic - Aluminum (CZ series) moves this sport to a new level, the increased performance and ease-of-use far exceeds anything we have seen in stilts before. The few flaws are tolerable and minute when compared to the benefits of upgrading. We highly recommend these for new stilters, and also for anyone who uses jumping stilts regularly to consider upgrading.

PowerStrider CZ Series: Conclusion

If you haven't already read the first two parts of my month long review of the PowerStrider CZ series. Please take a moment to do so Part One and Part Two.

Which brings us to the final portion of my review. After using this for a few weeks and really getting a solid feel on them. I can confidently measure performance, and now wear.

One of the most commonly modified aspects of all Powerstilts is the hoofs. As they wear down the quickest. When you run, jump, leap, and just walk. Your hooves slowly wear down as what ever surface you're on comes into contact with them. Most PowerBockers typically end up adding bits of bike or car tires to their PowerStilts referred to as "Tire Socks". Is this still required with the PowerStrider CZ Series?

I'll invite you to take a look at the photographs of the hoof wear after a couple hours of use. As you can see there is noticeable wear on the bottom of the soles. There is also a nice size chunk of rubber missing. This is typical of hooves from this brand, and not much different than the others currently out there.

I achieved this wear after a good couple mile run down a bike path. I believe the chunk came out due to stepping on a rock in the path. Overall I'd consider it normal for hoof wear. Not great, but not horrible.

Here you can see a side by side comparison of a brand new hoof, and my worn ones. The hooves at the time of being photographed had some good life left in them. So I'd estimate out of regular use of a few hours a week, you'd get 3 to 4 weeks before being required to switch.

Luckily, swapping hooves are a snap with the PowerStrider CZ Series. Instead of having to remove the entire assembly as pointed out in my previous reviews. All you need to do is remove four bolts, and swap out just the pads themselves.

In the picture on the right. You can see the pad being completely removed. This was really simple to do. The Powerstilts themselves actually came with the allen wrench to get the job done and it worked just as good as any I had in my own personal tool box.

In my opinion, if pricing is fair for the replacement pads. Modifications such as Tire Socks become a thing of the past with this new easy design.

As for the spring wear. I noticed the this series of stilts have no spring covers. They're just painted over, and in my normal use. I managed to take some tiny nicks, dings, and scratches throughout it. I'd highly recommend that if purchasing you should immediately cover them with tape, or another means to prolong the life of the spring. The springs lacking covers are a fairly negative aspect of the stilt, but not something that general powerbockers don't end up modifying anyways.

Overall my conclusion is;

They're light, sexy, and responsive.
My original skepticism over the cuff design is gone. It works great.
The bindings are poor, and need replaced. I'd recommend the Poweriser Bindings.
Hoof wear is normal.
The Springs need better protection.

The PowerStrider CZ series overall is a viable powerstilt to consider purchasing. I'd recommend them.

Is My Kid Too Young/Small for Poweriser Kids?

Q. My child is a little younger or under the weight range, but very athletic and energetic. I'm sure he'll grow into it... Should I buy him the Youth stilts?
Poweriser Kids 3050 are listed for ages 8 through 12 (66-110lbs)

In my experience even the small kids have a blast walking on stilts. Young kids usually pick it right up after a few mins, so balance and coordination is not a problem... but the main issue is fitting.

The ages and weight ranges on the Poweriser Kids 3050 is really just an estimate. The minimum size needed for kids to fit into the Poweriser Kids model stilts is mainly determined by the length of their legs. Fitting on the kids stilts requires a minimum of about 13 vertical inches between the bottom of the shoe and the bottom of the kneecap. The age and weight recommendations are less important than this particular dimension for fitting.

Make Adjustments using a Foam Insert
The 13" dimension requirement of kids stilts can be slightly adjusted by adding foam padding underneath the shoe. If you place a foot shaped piece of stiff foam under the shoe it will lift kids up, and this adjustment may be needed if the foot straps don't fit well with the tightest settings.

Adjusting the Cuffs of the Kids Stilts
Most kids will need to have the leg straps unscrewed and placed in the tightest position (smaller hole). Often even with this adjustment smaller kids will need wrap something such as padding or a towel around their calves to make a snug fit into the top two bindings.

Should you buy if the kids are too small?
My suggestion is to ensure that the kids properly fit the stilts. If the stilts don't fit right when they are first opened and adjustments are not made, it will be hard for the kid to use and uncomfortable as they are learning a new skill. Uncomfortable fit also pretty-much guarantees that they will lose interest in the sport. Fitting and comfort is one of the things that I emphasize, because powerbocking is supposed to be enjoyable!

Whatever you decide, the kids will definitely grow into the stilts before you know it.

As a reminder to parents: An adult should hold their hands and "spot" for the first 10 mins while the kids are first learning to balance.

Recommend: PowerStrider Olympic Aluminum Stilts

DC Power Stilts officially endorses the PowerStrider Olympic (cz) - Aluminum Stilts.
"The newest, most modern stilts offer a minimalist, lightweight design that makes it more fun and less tiring to use. Innovative features have been added: The traditional 'clack' with each step has been cleverly eliminated. These are not THE perfect pair of stilts and the main downside is their higher price. They do work safely and we highly recommend them for regular bockers and first-time buyers."
-David, DC Power Stilts

While we were initially excited by the pretty look of the stilts, we were skeptical of the performance and durability of this new design. DC Power Stilts put them to their paces to see if they would hold up on a variety of real-life conditions. We of course found some room for improvement, but the stilts performed well overall.

You can put your order in at our web shop... shipping is next business day.

Thank you to everyone on my team who has provided feedback on this model, and especially to DJ for his videos and tests.

Click here for all blogs about this model, including critical reviews and some ideas for improving them.

DC Tweed Ride: The Beginning of the Greatest Century

My friend called me and told me that we should do a fancy bike ride with a newly formed social and fashion group. Well my first thoughts about a bike ride in fancy classical attire were: first, I didn't have anything to wear and second, that I didn't have a bike. We briefly discussed wardrobe ideas, and we figured out something that I could do my eclectic clothing. Of course I figured I could run it on stilts... I checked the route and would probably be able to keep up with the bikes or at least take shortcuts if needed. I reluctantly agreed to attend the 11AM meetup.

Wow there were hundreds of riders in dapper and elegant attire at the start line. Many photographers and reporters had shown up, amazed at the crowd, and it completely stymied the organizers.

Of course the stilts were a big hit. Of the 300+ dandies and quaintrelles participating, I was the only dandy on stilts. The pace was exceedingly leisurely so I initially kept pace with the very front of the group and although many came whizzing past me on the downhill, I never ended up behind.

As Noted by NPR (Slide #7):

"This fellow had no trouble keeping up in his special jumping gizmo"

The Examiner even remarked that:
"One particularly exuberant dandy even jogged the route wearing power stilts crafted out of what appeared to be bicycle components."

(Not a sophisticated reporting piece... at least they got the type of stilts right)

Some video was taken by ReadSetDC, It shows vintage style with power stilts at about 1:42.

Yes, it was fun. People also really liked the hat.

PowerStrider CZ series: Part 2

Getting straight to it today. Here we are with my continuation of my review on the PowerStrider CZ series. If you have not read my initial impression I would recommend you do so before continuing.

But for those that have. I've made a brief video review in the video below. (Click the view original post button if you're viewing this from facebook) Please read a more detailed article following the video.

After getting some more in depth time on these powerstilts I have really taken note of their aspects that shine and the ones that leave you grumbling. Let's take a closer look at what I've discovered!

On one specific outing. I put on my powerstilts in front of my apartment. My end destination was the park across the street by the Mississippi River. I sat on the front step to my apartment building to gear up. I ended up struggling to get everything fastened correctly. I think I sat there for a good 5 minutes focusing on my foot straps alone.

Needless to say the frustrating nature of having plastic bindings was really becoming apparent. But after I put them on correctly, got up and went on my way. I was again very pleased with the weight of this set. They simply disappear on your feet. This made my quick jaunt across a cross walk, and down a small bike path to my end bocking destination very painless, and simply fun.

I ended up deciding to see how well they'd hold up in a serious jumping session. So I went at them for as long as I could. Again, very pleased with the fact it really seemed the height I was reaching was well OVER what I could on other models.

However, in putting some serious effort and work into the springs. I noticed something else fairly annoying. That again, went back to the bindings and now the foot pad.

I noticed that under heavy forces my heal would slide to one side or the other. This resulted in my landings being uneasy, unbalanced, and at times down right scary. This is due to a variety of factors.

The removal of the support rods.
The Removal of the plastic foot plate.
The Plastic Bindings.

In other models the support rods ended up holding my heel in place. I'd wedge it in there, and it would never move. By having room to move combined with the plastic heel of the foot pad. My foot never went anywhere. But with these I ended up at times feeling like I was walking like a duck. Even nearly clacking my springs together when landing. This was simply annoying!

I'd imagine that this could be rectified by tightening down the bindings even more so than normal on the rear strap. But again, the stock bindings are to frustrating. I kept having to sit back down after a few minutes to readjust so my heel would not slide.

I will admit that the new design certainly looks appealing. It's sleek, and sexy. But in use, I find myself already wanting to modify it. Deal breaker? Not quite, but something everyone should seriously consider before investing a lot in these? YES.

Moving along. I was very pleased to find that in my rough sessions. I did not have to readjust the cuff mechanism. Which had been a major worry of mine. They hold up great, and are very convenient to adjust for other users or to remove to store. This is something I hope other brands take note of. It seems to be in the direction of where others should go.

I absolutely love that the bushings are SILENT. I said it before in my last review, but the only noise I've heard while using these stilts. Is the noise of my hooves hitting the ground. I've been waiting for them to make a noise. But even after being rough on them. They remain completely silent.

However, I wish the nuts and bolts on this model could hold up to similar wear and tear claims. So far I've found myself readjusting and checking bolts after every use. Not out of good habit, but out of necessity. Because sure enough, after a couple hours I can feel something come loose.

In this phase of testing, I've had to tighten the hoof assembly on the spring. I've had to tighten the bolts from the support arc to the spring. I've had the stopper that's designed to keep the spring from bashing in the back of the foot pad come clear off. Due to the bolt coming loose.

Yes, it's good to check all your nuts and bolts after each use. But with other models, I've never actually had to adjust them as often as with these.

So to recap, the things that still shine to me are this;

The weight. They're light and feel great.

The height I can get. less energy for more height. Outstanding.

The no noise factor. No annoying CLACK CLACK.

The Cuff Mechanism works great. Adjust for yourself easily, then adjust them for a friend with as much ease.

Now the things that make me grumble;

The bindings! Cheap, annoying, ugh!

The slipping heel. Give me good bindings, or something to keep my heel from sliding around!

The nuts and bolts. I don't want to have to adjust these EVERY time I come back in from a session.

Now that I've had some time on these my opinion is that they are still a decent design. They are still worthy of maybe one day purchasing. The negatives aspects for the MOST part weigh less than the positives.

I get about another week on them before my review is done. I feel at this point that my opinion will remain the same. But time will tell all. Please come back here later for my conclusion.

And for an added bonus here is a video of XDbockerChris on them. Ignore the audio in this, it was windy so you can't hear anything I'm saying. xD

PowerStrider CZ series: Part 1

Continuing from the first initial review here. Your local Davenport, Iowa affiliate has received the new PowerStrider CZ series also known as the olympics, or the jumper pros. I will have them for an intensive three weeks review. My first impressions are as follows.

These Powerstilts have had a noticeable design change. First glance you'll notice an absence of the support rods to the foot pad. The removal of the plastic footpad. To be replaced by a simple aluminum one. A new cuff tightening mechanism, the frame being directly bolted to the spring at the lower diagonal rod, and the removal of most of the metal for the hoof assembly.

Close inspection reveals that the length of the spring is actually longer than what other models in the past has offered. In theory this should allow for greater return, translating into greater height.

Upon first picking them up. The first thing that's apparent is the weight. Due to the stripping of other past design parts, these are noticeably lighter than any past stilt I have used. The night I received them, I put them on and ran around for about 20 minutes. The difference in weight might be slight. But the feeling is HUGE. They feel great on your feet.

Now whether the changes to the frame are positive and whether the new lightness comes at a price are yet to be seen. But as of now in my first impression, and a few hours use on the stilts. They seem to hold up fine.

The change to the foot pads certainly look a lot sleeker. In actual use however, I've found that my heel has room to slide slightly. Due to the fact there is nothing there to hold it in place as the old support rods, and footpads used to do. Now I have large feet (size 16 US) so I'd imagine users with smaller feet would have similar if not worse problems. The remedy to the issue is solved by tightening the straps even more so than normal. But this is difficult in the rear strap. The toe strap however, seemed fine.

The bindings on a whole on the other hand are perhaps my largest complaint thus far. They're painted metallic, but are cheap plastic. This results in the user having to struggle to get the straps tight enough. Due to the plastic teeth not "biting" hard enough. Are they usable? Yes. Brand new they get the job done. They don't come loose once tightened. But an advanced user may become frustrated at the annoyance of the bindings and opt to upgrade once they start to wear.

Looking down the stilt. You'll notice that the lower diagonal frame from the footpad to the spring has been changed. To a new aluminum curved bar design. Which instead of clamping around the spring, bolts directly through it. This design has been done before in the past and has always brought much worry from the powerbocking community. But in my initial use. The design seems to be solid. The new bearings are absolutely smooth and silent.

In use I have gotten no "CLACKS" or frame wobbles. The only noise I have heard so far is the sound of my hooves hitting the ground. The bolts through the spring have so far remained tight and secure. I have not needed to readjust them.

I'm actually very interested in this portion of the stilts design. I am regularly a poweriser advanced user. I use 90120 springs, and can get full compression at will. The powerstriders I have received for review are 70kg springs. They're nice and responsive and give back great energy return. Yet, either due to the new method the spring is attached or from the added length of the spring. I have to put considerable effort to reach the bottom 90% of the spring.

I have also been able to reach very good height with less effort as my previous stilts. Now, will this design hold up? Will the bolts wobble through the spring? Will the springs wear to fast? That is yet to be seen, and more testing is needed. Luckily, this review will have 2 more parts over the rest of the weeks I have them.

Continuing on down the stilt you'll spot that the hoof assemble has completely changed. It no longer goes up the bottom quarter of the spring, and instead just sits very simply at the bottom. This has proven to be a major weight reducer.

The newest change to this design is that instead of replacing the entire assembly. The rubber hoof pads can just be unscrewed off by themselves and replaced. As mentioned in the initial review. This may be a good thing, or proven to be a weak point. So far I have put the stilts through a 2 mile run down a bike path to purposely test hoof wear and they held up fine.

The only negative aspect that has shown itself thus far. Is that the assembly that remains attached to the spring worked itself loose by a hair resulting in a slight vibration as I ran down the bike path. This was easily rectified by readjusting the bolts. I'm paying close attention to this portion of the stilt in my future tests, and plan on putting it through another intense run, followed by a jumping session.

Quickly popping back to the top of the spring. You'll notice that the cuff attachment mechanism has been changed. Initially I was very skeptical at the new design. But it has so far held up without need to readjustment.

Overall my initial thoughts of this new model are;

I like them. The design is sleek and sexy. They're uber light and nearly disappear on your feet. The springs are smooth, and the energy return is impressive. The height I've attained so far has surprised me. I remain skeptical at the cuff mechanism. I am also keeping a close eye on the hooves. I dislike the bindings, but they are not a deal breaker.

If they survive the rest of my testings, and are reasonably priced. I would say this model is the next on my list of things to buy.

As an added bonus. Take a look at the following video of my first test run on the stilts. Keep in mind that the video was taken on a windy day, and from my cell phone.

Keep an eye out for the following portions of my review. I'll be sure to include a more detailed video, and tons more information.

Tips for Newbies: Look up!

Something often over looked when starting out powerbocking. Is having correct posture combined with Jumping Technique. Many people start out by doing a jump, head looking down at the ground to see where they land. Seems like the safe method right?


This may seem like a good thing to do. But by tilting your head down to look at the ground. You bring your center of balance forward, and you bend your body. As you come down into a landing, the curve of your body ends up absorbing some of the shock your springs desperately needed to send you flying just a bit higher.

It's true that you need to be aware of your surroundings. But look with your eyes, and not your head. Always try to look about 20 feet or so ahead of you. This will keep your body up straight, and not shift your balance.

This is a vital skill to get down, it really helps you out. Even if it doesn't seem like it would. For instance, if I look down at the ground, jump and try to do a Split Kick Double Grab, I can get my hand to my toe, but not my other hand to my back spring. BUT when I look up and forward, I'm able to grab my toe, and grasp my back spring. Little things DO matter!

Bock Report: Midwest Meet of September

This last Sunday on the 27th of September. The Midwest area had a small meetup. We all traveled to Plainfield, Illinois to get together and Powerbock, and discuss all things Powerbocking.

The local members of the XD Bockers, Chris and myself meet up with BboyVC at Renwick Skate park. We each had a 2 and half hour drive. But it ended up being well worth it. Despite the low turn out (this time).

Arriving at just after 11AM. We all checked out the park on what it had to offer.

Free public park, features: mini ramp-funbox-4ft quater- 6ft quater with declining hieght. Pyramid with down rail and ledge. Cement hips allow you to roll into the park, there are two down rail down the hips.
no running water
no electric

Strapping our Powerstilts on. We headed to a nearby basketball court to essentially warm up. After several minutes of jumping, bounding, and stretching our muscles. We headed to the park to jump off a grind box, attempt to walk along a grind rail, and to each take turns showing off tricks, and our jumping technique.

It was a real good time. For about an hour or so, split kicks, spring grabs, straddles, toe grabs, 180s, and 360s could be seen in the park. Which was surrounded by two local soccer games. After taking turns jumping off the 6 foot ramps, and attempting to vault their back guard rails.

I actually broke a stopper coming down from a split kick to toe grab. So I had to put my powerstilts up for the meet. At which point we all attempted a new method of getting off the ground unaided called the "Eltovator" (I'll get a tip guide to this soon).

Here is videos of my success.

Here is XDbockerChris

After pulling that off several times. We moved to other zany antics in the grass as shown...

BboyVC took the chance to show off his flips. He actually landed nearly all of them. Of course the videos I have are of his bails.

following that he attempted a cartwheel.

Needless to say at around 4pm we were all pretty much wearing down. Practicing that weird method of getting up turned out to be very taxing. I'd strongly urge anyone else that attempts, to try it in the grass first. The chance for injury is far greater.

After cooling off by a closed concession stand for half an hour. We all headed off to Mcdonalds for some dinner before heading our own ways back home. Overall the meet turned out to be a good time. Hopefully, with more planning our future meets will be even bigger, and better. Keep an eye here for more future announcements of meet ups, and be sure to keep an eye on the XD Bockers facebook group for more planning details.

For more details on the past event. Please check out it's official event page here.

First look: PowerStrider Olympics (CZ Model)

In Summary:
This new model has a good design and offers innovative features and impressive weight reduction without compromise in performance... I'm excited about this model, but how well will they hold up? More testing is needed.

The Details:
Shipping for this model consists of a smaller box and the lighter weight is immediately evident. The reason the box is so small is because the leg cuff is not attached. I actually think this is a smart move because it saves on box volume and assembled stilts still need to be adjusted and fitted by the end user. The stilts are not symmetrical, so the user needs to figure out right and left during assembly. (Remember the buckles should be on the outside when attached.)

Impressions while putting them on. Again the lightweight nature of the stilts is very nice. The footpads are minimal but it saves on weight and they look cool. Wearing boots, the front foot strap was a little tight, so it seems like people with unusually wide feet may need to add washers or do some tweaking to get a comfortable fit on the front foot strap.

Unfortunately the metallic-painted buckles are completely plastic. So they won't have the durability, grip and power that a metal buckle would offer. They do work nicely, so out-of-the-box they seem fine.

The instruction manual goes beyond the normal operating instructions and offers some good tips for learning and doing tricks. Unfortunately it's been translated mostly into "ingrish" and could use some editing by a native English speaker. I also noticed that the content was slightly different between the Chinese manual has different content! For example, the English version of the manual offers tips and photos from the Swebounce website while the Chinese version doesn't seem to have the photos and descriptions of jumping tricks.

The Cuff is comfortable and easy to adjust thanks to an innovative new clamp that can be loosen or tighten for adjustment via one lever and a thumb screw. The cuff is adjustable in the usual ways, so be sure you check to make sure the height and centering are correct.

A detachable hoof is a great idea, but one drawback is that the rubber hoof gets metal screw attachments sticking into it, which kind of makes those become weak points for wear. Of course, it is very nice to be able to just replace the rubber part without replacing an entire hoof assembly.

Starting out the first thing to note is how the bBearings are super smooth on these. Whisper quiet, There is no "clack"! The reduced weight of the stilts seem to make everything a little bit easier. The springs are nice and responsive and don't bottom out from running or jumping big. I'm in the middle of the 70kg weight range, so it seems that they are well calibrated.

Jumping and running works the same as any other pair of stilts but the lighter weight of the PowerStrider Olympics (CZ) feels good with every step.

After a couple hours of running and jumping, getting yogurt and hanging around town on these stilts there aren't any noticeable scratches, and the springs are pretty pristine considering that there is no spring cover. Inspecting the cuff attachment points, the single-screw and lever seems to have held them tight and there aren't any signs of splitting or wear on any of the parts. Wear on the hoof seems normal.

So far we are excited by the PowerStrider Olympics (CZ) since there don't seem to be any inherent flaws or design compromises. They offer good design, impressive weight reduction, and some other innovations.

More Testing is needed since we've only been on the stilts for one day. DC Power Stilts wants to see durability and performance over time, with a range of conditions. We will most likely endorse it if it hold up.

Pricing and economic factors are going to be important to the overall picture and DC Power Stilts will need to examine that to know whether we can offer this product or whether it will be a good value to our customers.

Tips for Newbies: Inspect your powerstilts!

One key thing to remember when you're out having a blast on your powerstilts. By either standing high above the crowds, running at great speed, jumping really high, or by pulling off some insane tricks. When you land, and sit down to take them off. Be sure to inspect your stilts after each use.

Look them up and down to ensure that all the bolts are secure, nothing is lose, and everything is in tip top shape. Doing this will help you get the most out of the life of your stilts.

If you do eventually find a problem, fix it and don't hesitate to get replacement parts! Doing so early on will save you loads down the line if that simple part ends up causing major damage later.

Faster Than A Road Runner

DJ Bothwell, 23 of Davenport; His Brother Christopher 17. of Oquawka, IL and their friend Josie Grant, 18 use power stilts to jump around Wednesday in Dankwardt Park. DJ Bothwell was in town giving a Demostration, and stayed to play with his brother and friend. Most users can Balance and walk in 10 minutes, and advanced users can leap 6 feet and run 25mph.

Taken from the Burlington Hawkeye on July 31st 2009. This article features nearly all of the XD Bockers. That afternoon, we put on a short demo for a camp, and then bocked for a couple hours for some skaters, and our own fun.

Tricking: Split Kick

Want to show off just how much air you're really getting? Try a split kick, it really helps people realize just how high you actually go. Put on those safety pads and give this one a go!

Split Kick

Basically, As you jump in the air, pull one leg behind you, and kick the other infront as far as you can. The further you can stretch the better it is. Flexibility and timing is key.

This is actually one of my favorite tricks. It looks great in photos, and is easy to do once you've mastered the basics, and can maintain balance in air. To get the best split kicks, I've found that varying what you do with your arms in air helps a lot. Bring one arm up, one back, ect. Variety is key in making the entire trick nice.

River Roots Live/Ribfest 2009

This last weekend, this local affiliate from Davenport Iowa. Spent a short time bocking for the crowds at River Roots Live, and Ribfest. A local street festival which has combined with previous years paid concerts, and a crazy rib eating event. To create some super finger licking, and tapping goodness for free.

On August 22nd, I went out during a spare hour and bocked around the closed streets. Taking in the sights, and sounds of the free concert.

I just so happened to be captured by a photographer taking in pictures of the event.

D. J. Bothwell of Davenport bounces along second street in downtown Davenport wearing his jumping stilts while taking in the music and food Saturday afternoon at the River Roots Live Music Fest and Ribfest.

Tricking: Spring Grab

Time to pull off one of my favorite basic tricks! Strap on those pads and keep reading to learn about spring grabs!

Spring Grab

This trick can be pulled off in dozens of varieties, each a different trick. But at the base, is the spring grab. In mid-air bend back and grab one of your springs. Bring your leg back closer to your hand to help out. Takes practice, but looks cool. You can see XDvandalJake and myself both pulling these off in the photo.

Another more advanced version of this trick is called the Double Spring Grab. Essentially instead of just grabbing one spring with one hand. You take both hands back and grab both springs. As always, don't forget to give yourself time to land with any variation of the spring grab trick.

Tricking: Star

Read to learn how to trick? Let's get our safety gear on, and get to it. Today we'll be covering a very simple trick to do. That looks great on camera.

The Star!

The star is a very simple trick to pull off. It's basically a modified trampoline trick fitted for powerbocking. At the height of your jump. You bring out you legs angled from you, and raise your arms up at an angle. The point is so that you resemble a star in mid-air. Don't forget to give yourself time to land!

This ones fairly easy to pull off. Theres no special tricks, only just timing and practice.

Go give it a try!

Tips for Newbies: Start Tricking - Tucks

Tricking is usually what everyone wants to do straight away. When we first find out about these crazy things called Jumping Stilts. A lot of us end up searching the web, and stumble upon countless videos of other people, flipping, jumping off crazy things, and performing many different tricks on them.

It's no wonder when we finally get a set of our own. That we'd want to jump straight into pulling off all sorts of wild powerbocking tricks. Well, once you've mastered how to stand, walk, run, jump, and do it all well. Without thinking about performing each of the steps. I'd say you're ready to hop from stage 1 of learning, and go into the beginning stages of tricking. Be sure to wear your pads and helmet though! At this point it's even more vital then ever! BE SAFE.

What kind of tricks are there? Well there is countless named tricks, and there is always new ones being created. Our sport of powerbocking is still very young and accordingly, we're still learning more and more insane things to do.

A short list of basic ones would go like so:
  • Tuck
  • Star
  • Spring Grab
  • Double Spring Grab
  • Pike
  • Split Kick

Among many other variations and more advanced tricks. But let's take it slow shall we? I personally started learning the very basic trick the tuck first. Let me explain what exactly it is, and how I do it.

A tuck is basically where when you're at the top of your jump. You bring your knees towards your chest, hold them there in air as if you're "tucked" in a ball of sorts.

Tucking takes a certain amount of timing, flexibility, and technique to get down right. The longer you're able to hold one in the air the better the trick looks. Just never forget to give yourself enough time to land. At first, you'll find your tucks only being split second long. But eventually you'll master the timing and get enough height to do it right.

Be sure to keep a clear head, be calm and always just calmly grab your knees as you bring them up. Hold them towards your chest, and let go. Practice this over and over until you get it down without thinking about it. In the included photo, you can see I'm starting to come down from a tuck. As a proper one would of had very little air space in between my legs and body.

Go get practicing, and I'll explain another trick next time!

Bock Spot: LeClaire Park, Davenport, Iowa.

Taking a short break from my tip series of articles. I am taking this chance to share with you. Some of the XD Bockers favorite local powerbocking spots of the Midwest. Starting close to home in the Quad Cities very own LeClaire Park.

LeClaire Park is located right on the banks of the Mississippi River as it is also located near Modern Woodmen Park. LeClaire Park hosts many summer events including River Roots Live and Ribfest

This park is situated along the "Great River Trail" a several mile bike path the stretches all along the banks of the river, across a bridge and along the Illinois side and back again. Because of this, it is excellent for long range running sessions on Jumping Stilts. I've found myself many a afternoon running from one part of the bike path to another. It's very scenic for Iowa, and offers several interesting stops along the way. (More on those spots another article!)

At the front of the park is a massive sound stage. Which at my rough guess is at least 5 and half feet tall. I find much enjoyment in running towards the stage, leaping upon it on my knees, pushing off, going out a couple feet. Jumping, and continue out a few feet, rotate in air and come back to the stage. Only to leap back up, push off and repeat in the same constant jump. It's great fun, and a super work out.

In front of the stage is a rather large flat clear area great for jumping around. I personally practice most of my in air rotations here.

Please take a moment and watch these videos of the area. Videos explain better than written words ever could! Right? Right?!

Overall I consider this spot a personal favorite, as it offers more than one type of powerbocking activity, and is close to home. It's usually not over crowded. It also offers huge grassy areas for practice.

Tips for Newbies: Gaining serious height

Have you had a chance to work on your "Kangas", and "Pogos"? Can you get up from the ground alone? Have your proper safety gear strapped on? Well, let's move forward and work on getting what everyone really wants with their Powerstilts. Serious Height.

Gaining serious height
Gaining serious height takes confidence and guts. You have to commit yourself completely to it, you have to throw all your weight and not second guess yourself. I've found that utilizing a chain of all jumping techniques works best. Start with a pogo jump, go to a kanga jump, use your whole body. For best results I've always started from a run, then leaped into a kanga jump and continue leaping in a forward motion. It can be done in place, but takes practice to get the same height.
The best method I found starting out. I like to call the "Set up " which takes a series of steps.

  • 1st-You pick your spot to jump.

  • 2nd- You take a moment and breath.
  • 3rd- After you have sized up your jump. Get ready to take several steps. Act as if you're going into a run.

  • 4th, use the same technique you learned with pogoing to launch yourself in the air. As you go upward bring your arms up with you. Because you started this with a run, you'll be going up and forward, keep this in mind.

  • 5th- As you go down into a land. You'll be several feet from your "launching point" Put both feet down, into a "Kanga Land". As you land, bring your arms down hard. This will help give you an extra boost. As you get propelled back up. Bring your arms back up again. You'll end up still being propelled forward.

  • Finally- As you're up in result to your first "Kanga Jump" prepare for another land. Utilize the same techniques as before. As you come down bring your arms with you at the right moment to keep yourself going. Continue this steps for as long as you can, or as long as you'd like. To stop quickly, I found that at just learning. Instead of Kanga Landing, I could use a one footed land, or a "pogo land" to kill my jump by bottoming on one foot.

Keep in mind that those steps are going to have you jumping forward in a straight line. This is what I found to be the best method starting out. Once you get the feel of gaining big air this way. It's a lot easier to do jumps say, stationary or in other variations.

Just go at your own pace, be safe, and you'll have tons of fun. Thanks for reading these tips from you local Davenport, Iowa Affiliate.

Tips for Newbies: Kangas

So you can walk, you can pogo, you can run, and most importantly you can get up without help? Great, now do you have all your proper safety gear? Elbow Pads, Knee Pads, Wrist Guards, and a helmet? Alright, perfect. Read on and I'll teach you what we like to call "Kangas" in the powerbocking community.

Kanga Jumping

Kanga Jumping is really just like Pogo Jumping. Except it uses BOTH stilts to get the max power out of them. This personally took me sometime to get down. As using both stilts will at first unbalance you in the air, and on your landings. Due to it using more power, and requires the timing of using both legs as one.

In my experience I started by just jumping in place. I would launch with both feet first, and just practice on jumping once. Until I became confident in my landings. I recommend doing it near a wall, or something to incase you need to fall forward.

I learned by jumping from one point to a safety aid. As I became more confident I eventually went further and further away until I stopped using aids altogether. To get the best jumps, launch yourself from a pogo jump into a kanga jump. Essentially, you jump with one leg. Land on that leg, propel upwards and land on both legs, which launches you for high air.

Kanga Bouncing

Kanga Bouncing like pogo bouncing is just the continued Kanga Jump. Once comfortable launching yourself in the air once. Begin to learn to do it over and over. Doing this is great fun, and really helps you learn to throw your weight into the stilts and get higher and higher air.

I find that when you launch yourself once. The best method to keep going is to throw your whole body into each landing. Throw your arms down as you land. It really helps get good results.

Here is a short video someone shot of me at an Anime Convention. It demostrates the basic principles of two footed jumping.

Thanks for reading, now get to bocking!

Tips for Newbies: Learning to run


It's time to strap on those powerstilts, stand up and take off running. Careful, you'll be moving fast in no time. (Some of us can reach 20mph!) Don't forget to wear your safety gear as you try this!

Learning to run

Now that you've gotten down pogo bouncing from one leg to another. Utilize those basic skills and learn to run. Or in bockings case more learn to bound. Running with bocks is unlike running without them. So prepare to unlearn what you know, and relearn how to on stilts.

Essentially you put weight down on one leg, launch yourself forward and land with the other. Repeat this process by quickening the pace, and lengthening your stride. It takes a while to learn, but eventually you will learn how to let the stilts propel you forward. Just remember, put your weight in your heel and talk wider and wider steps.

Want to stop? At first just stick to slowly taking closer and closer steps. But eventually start utilizing pogo bouncing to stop your momentum. The best method to stop quickly is to exert all your forward force into upward momentum in a kanga jump. But get that down as time goes on.

Well there you have yet another small tip from your local Davenport, Iowa affiliate.

Tips for Newbies: Boing - boing

Let's get straight to it today. You ready for to get that bounce in your step? Have you already learned to walk? Well let's start into those one footed jumps, and bounces I like to call "Pogos". Continue reading to find out just what exactly "Pogo Jumping, and Bouncing" really is! Strap on those pads, helmets, and get to reading, then get up and go!

Pogo Jumping

Pogo Jumping is just what I like to call one legged jumps. It's a vital skill to learn to get yourself started in the bocking world. Now that you've learned to walk you'll want to learn to jump. But let's start with just one leg. Trust me, it's better to get this down first. Essentially a pogo jump is you putting weight down on one leg, launch yourself up, then landing on that leg and letting the spring propel you in the air and finally landing again. Shazam! pogo jump. Remember to center your weight in your heel. It really helps in balance and getting the most bounce.

Pogo Bouncing

Pogo Bouncing is really just a continued Pogo Jump. You launch yourself into a jump, land, go up, land again and continue. You do this all with one leg, you can switch legs to spice things up and help keep your balance. It's good to learn how to do it every which way. Getting this down is really great for your confidence, the fun factor and is a great way to wow your friends as you learn.

Tips for Newbies: Getting up Unaided

It's time for yet another small tip. Direct from XDvandalDJ your Midwest local affiliate. Please read and learn from my personal experience. It helped me, and maybe just maybe it might help you. Be safe and be careful though! Now, let's try and get off the ground... without help!

Getting up Unaided

This is one of the most important skills to learn and get down. Seriously consider practicing this early on. Just picture this, you're out on your new stilts. You've attracted a crowd, then WHOAH! you fall. There goes your dignity. But WAIT! You can somewhat regain it back by getting up WITHOUT the help of your laughing friends.

This took me a few tries to learn. Plan to fall while doing this. Please, please wear proper safety gear, helmet, wrist guards, elbow, and knee pads.

Basically, you get on both knees leaning forward. Put your strongest leg up front, with the hoof on the ground and your knee bent. Pull it close to you, and lean your weight over it. Use a hand to grip it if needed. Push up from that leg, as you do pop your other leg around and then land on both feet.

Sounds and looks easier than it is. But eventually you'll get it down. Practice, practice, practice and eventually you'll pop up from the ground without even thinking about it.

Need more visual help? I personally learned from watching this video by BalthezarArith

Good luck!

Tips for Newbies: First Steps

Hello sirs and madams!

Below is the first edition in a series of articles written based upon my own personal experience. Keep reading and it might benefit you. Or at the very least entertain you! Let us begin this several part article with.... the first steps!

First Steps
It's really difficult to explain how to walk in these. You basically have to learn on your own. All I can basically tell you is ways I found to be easiest. First find something tall to sit on. Many people stress that you need to learn to get up from a fall right away. But I found that I needed to learn to stand and hold my balance before popping up to my feet from the ground. So I found something tall to sit on, put my bocks on and then stand. First it was difficult just to stand, so I held myself up on a nearby wall. What you need to do is just hold yourself there and get the feel of the stilts. Basically with these it's impossible to stay completely still. You need to stay constantly moving to keep balance. You'll learn in time to hold yourself without even thinking and remaining still longer and longer. But right off you're going to be all over the place. Just move one foot and then the other back and forth. Slowly getting to where you can take your hands from the wall. As you find you can do this longer and longer. Start slowly walking up and down the wall. DO NOT try and jump at this point. Just focus on staying upright. As you progress either get a friend to walk out with you. Or stay with the wall until you feel comfortable. Personally it took me a good 20 minutes to learn to stay up, and then half an hour to get to the point of walking unaided. Everybody differs though, don't worry about it and be safe.

Please take a moment and observe the video below of me aiding my friend Jeff in his first steps on stilts. Please keep in mind that this video is not a reflection of the lessons DCPowerStilts offer. DCPowerStilts offer much gentler steps and require the proper safety gear. Falling rarely, if ever occurs.

Ouch right? Well there you have my first tips for newbies. Keep checking back here often for more!

Why do you only sell certain brands of stilts?

This broken hoof is a result of a few hours of normal usage of a pair of the Chinese knock-off brand Powerizer Pro stilts. They may have changed their name to Air-Trekker, Power Strider, Flying Locust, or whatever, but design flaws and low manufacturing quality from this brand is well known and documented by numerous users. You might save a few dollars to buy a pair of these, but you'll get poor quality. Luckily, my customer was able to retrofit a pair of good Poweriser hooves in its place.

As a stilts dealer that represents bockers, I feel that stilts should be made such that they are suitable for regular usage. Because your safety rides on your stilts, only well-tested, quality products should be used.

DC Power Stilts is a small business, independent dealership, and we are able to represent any brands of stilts that we want to. Right now the best quality vs value for most users is going to be a pair of stilts from the Poweriser brand. For advanced users and professional performers, please ask me about the other alternatives. I can steer you away from bad brands and towards the good, proven products.

4th of July, Bix7 Streetfest, and more

Hello sirs and madams!

XDvandalDJ here yet again. With an exciting, yet long over due. Bock report! How did invading Red, White, Boom of Davenport, Iowa go? What about this Bix 7 Streetfest thing? Or what else have I and my fellow XD Bockers been up to? Well continue reading for full details.

The invasion on the 4th previously planned Here and mentioned in this very blog. Went fairly well. I along with JosieFailed, and XDbockerChris(As ground crew) had a blast. Excitement was high, we gathered on friday evening. Grilled out, and showed hundreds what Jumping Stilts were really like, with a marvelous backdrop of fireworks to boot! However, I regret to inform you that we had no pictures or videos taken for this event.

Onward to the Bix 7 Streetfest! This was a couple weekends ago. The Streetfest is in celebration of a massive 7 mile uphill, downhill, crazy marathon ran in honor of an old jazz musician. In downtown Davenport several streets were closed for this to happen. Many tents erected, many venders to sell, and a few concerts here and there. In the midsts of the thousands that gathered. I personally set forth into the crowds. Enjoying the ease of moving through them at a full head and shoulders taller than the rest.

I spent my time walking through the crowds, and jumping like a madman in available clearings. I really took advantage of the closed streets and really loved the intersections. I was invited to perform at a concert, and even walked past a newsreporter on bocks which briefly captured me.

JosieFailed later joined me for another go the final day of the festival. We bocked in front of even larger crowds, and were actually given free toy light sabers by some other attendees. Overall we had a very great time at this second "Invasion" event. Next year will be another planned event for sure.

Other than those two larger events. On this last Wednesday Josiefailed and I traveled to Burlington, Iowa to meet with XDbockerChris, and XDvandalJake. Myself, Josiefailed, and XDbockerChris all put on a short demo for a local camp for the mentally disabled that XDvandalJake helped run. We wowed many young kids that afternoon, and were just completely jazzed by the interest and energy these kids put out. We conducted this demo at Dankwart park, and later moved it to the skatepark there. When some local skaters expressed great interests. We were also photographed for the local paper. Check back at this blog for an updated entry, if and when those photos are published.

When XDvandalJake got off work from the camp, we all rounded the evening off with personal practice, and all around having fun on our jumping stilts.

For any one local looking to meet for a try out. Or to just have fun with us. Visit our group page, email me. Or check out this thread for short announcements of our day to day meetings. here

What are the replaceable parts?

How frequently do they need replacement?
Wear vs Usage really depends on a lot of factors. Note that the Poweriser warranty doesn't cover damages due to normal (or improper) use.

Poweriser Hooves are the most common part in need of replacement. If you are using your stilts on soft surfaces such as dirt or grass, the hooves will last years and years. If you are using them primarily to jump, they will last a while, but running and moving on pavement wears them down more quickly. In my experience, hooves last about one and a half season with occasional usage on pavement. This can be mitigated by the use of "tire socks", a tire or something rubber wrapped around the hooves.

Poweriser Springs are designed not to catastrophically fail, but over time it will wear more and more. The appropriate time to replace the spring is when you find the stilts "bottoming out" during regular usage. Again there's no established range on these because it depends greatly on the weight of the user, the kinds of usage, and any damage. My first pair of stilts have been used a few hours each week, and the spring is still fine after a year and a half... But I'm at the low end of the spring weight range.

The bearings will wear out if they are not occasionally maintained. Because of the bearings, exposure to water sand and grit should be avoided.

The rest of the parts should last for most of the lifetime of the stilts, but may need replacements from heavy usage or incidents that cause specific damage.

Capital Bocking USA Report

There were nine participants that showed up (that found us) and we came from impressive swath of the country. US States represented were: TX, VT, WV, MA, PA, MD, NY. Also represented was the UK. Most importantly, everyone had fun and no one got hurt.

From the DC Power Stilts Youtube Channel

The DC Power Stilts Challenge Format
Basically the format consists series of mostly easy/ intermediate "challenges" which participants could opt to participate in for points. Some challenges were harder and worth more points, and some were team or head-to-head competitions. Bonus points were awarded to the farthest traveled, the youngest, the oldest, the most feminine, knowledge of congressional procedures, and even for coming to the pizza party. The "secret point swap" made it partly a survivor-style, team strategy game as well. With a variety of skill levels represented and an emphasis on participation, all those in attendance were energized throughout each of the activities.

The first part of the competition was structured challenges on DC's great bocking terrain. Some people tried the terrain challenges for the first time.

DC Power Stilts threw down a good pizza party to start the weekend, and hopefully we indoctrinated everyone with our business philosophy and commitment to powerbocking.

From the DC Power Stilts Youtube Channel

The afternoon consisted of walking/touring in a popular and historic area of town with ice-cream treat. Points were awarded for crossing the bridge from VA into DC. It was hot, but weather stayed dry.

Sunday was a relaxed format where we had breakfast together and hung out in a park near a big farmers/craft market. We got breakfast, played with the camera a bit, and relaxed. Then we did the secret point swap followed by a somber awards ceremony. With obstacle courses, races, group challenges, quizzes, bonus awards, and point swapping, the winners really earned their prizes. I'll profile the event winners in a future blog.

One thing that stands out is that the DC event was a huge success in terms of publicity and local awareness. We were prominently featured with a full color photo and listing on the first page of the Washington Post Weekend Section. I'm estimating that at least 50 people came to spectate the various challenge events, and there were also about 50 that attended the Free try-out lessons after the competition event, which quickly reached capacity. (Thanks to Dominion for pitching in to help teach and organize the crowd!). It seems that about half of those taking lessons were youths, so it was very nice to see that level of interest in our sport.

Powerbocking was extremely visible throughout the city this weekend, as evidenced by a number of local acquaintances who contacted me after seeing people on stilts. I was even riding up the elevator when I overheard two people talking about "people jumping on stilts... in the park".

It was some work to organize and host everyone but I wish I had you all in town every weekend! Be sure and attend next year.

Red, White, BOOM! Eh, Bock!

The end of June is upon us. Barbecues and summer events are currently growing in occurrence. Capital Bock is just days away from happening in Washington, DC. BUT! The start of July is just around the corner, more picnics, more barbecues... and was that an explosion?

Yes, that's right the 4th of July weekend is coming up! Currently, the XD Bockers are planning on "Invading" Red, White, BOOM! The Quad Cities Fireworks Festival for the 4th of July. It's hosted in Davenport, Iowa, and Rock Island, Illinois. Fireworks are shot off over the Mississippi River for a super cool show. We plan to attend the cities official events on our PowerStilts. We'll meet up on the river front, bock down the 3 mile bike bath. Head over to the crowds, do some jumps in the 30 thousand square foot skate park (Which has a great view), and just spontaneously enjoy the 4th of July.

We welcome any one to come out and join our small gathering. For more information, please visit our Facebook Event Page to check it out. Don't forget to RSVP if you can make it. If all goes well, we plan on more "Invasion Events". They'll be full of good laughs, good times, and good height. xD
