An Innovative Way To Add Padding to Air-Trekker Knee Bars.

The adult model Air-Trekker jumping stilt features a padded knee bar that you slip you foot and leg through.  The knee bar rests just below you knee cap.  Although nothing needs to be added to begin jumping, many have found that adding some padding to the knee bar, creates a much tighter fit around the upper calf.  A tighter fit gives the jumper more stability and confidence.

How you do add padding?

1.  Go to YouTube and search:  Air-Trekker padding.

2. Or check out the video below sent to us by Zach Benedict.  The video below is his idea.  Way to go Zach.

Tyre Socks – save your Feet!

My Canadian friend, Mark Kelly, gave me permission to post this short blog on our site.  It’s a valuable document describing one option on how to build “tyre socks” for you jumping stilts.  “Tyre socks” is a British term given to an attempt to prolong the life of your jumping stilt’s feet.

Many performers utilize the method described below.  They use all sorts of materials, from wagon wheels, to mountain bike treads, to carpet.  I’ve even seen one unit with small kids shoes attached to the bottom of the feet.

Tire socks are a inexpensive easy way to extend the life of your rubber pads/feet/hooves on your jumping stilts.It works for all brands and models including poweriser ,powerstrider ,skyrunner ,air-trekkers ,powerskips ,projumps ,flyjumper ,upwing ,powerizer ,powerskip and many of the others.Here are simple instructions on how to make yourself a set and extend the life of the pads on your jumping stilts.

This is all you need to make yourself a pair of tire socks and extend the life of any jumping stilts rubber pads. Duct tape,2.5 inch hose clamps and a 12 inch kids tire the harder the better.

image002Cut the tire in half using a hacksaw or a pair of snips.You will feel that there is a wire that goes around on each side of the tire you can cut that off the tire if you want to .That is preference and also depends on the width of the tire. You can use 2 clamps or 3 im going to use 2.
image003Fully extend the hose clamps and put them over the foot of your stilt and place the middle of the tire on the end of the rubber foot as shown.
image004Fold the tire over the stilt as shown making sure it is tight around the foot pad and tighten the clamps untill they hold it tight.
image005Wrap the duct tape around the loose ends of the hose clamps so they dont flop around.You can use different color tires and tape for you desired effect.
image006There you have it an easy way to save your rubber pads and your money.

Changing Springs On Jumping Stilts

Bockers (term used to describe people who own and use jumping stilts) who  have become addicted to this new extreme sport/fitness product will eventually want to, or need to, change out their springs.

Whether they have the desire to try a heavier spring (higher weight category) or feel it’s time to install a fresh new spring, they will need to know how to properly change them out.

As bockers move through the initial learning curve (2-3 weeks or 10-15 sessions) they begin to realize how strong their legs have become.  They sense a fresh level of fitness that they haven’t felt before.   Once one becomes aware of this new feeling of strength and fitness, the desire to “crank” or become more free on the springs becomes very apparent.

After a few months,  some bockers may make the decision to try a bigger spring.  It is not recommended that one move up until you are very comfortable on your jumping stilts and your legs are strong, because a larger spring will be tougher to bend.  Unless one is very fit, a larger spring will feel like wooden stilts, not jumping stilts.

Why try a bigger spring?  A bigger spring will allow the same weighted person to jumping much higher, opening up the opportunity for many new tricks.

Mr. Boeck, the inventor of jumping stilts, states that the carbon fiber springs used on most jumping stilts, have a life of around 500 hours.  Sure they can last longer if one isn’t very aggressive with them.  Their life span can also be diminished if one falls alot and scrapes the springs, knicks the springs, or allows someone much heavier to use their units.

They are made with milliions of tiny carbon fiberglass threads fused together, so scraping or knicking the springs can break many fibers, thus weakening the springs and shortening their life.

Eventually you will need to change out your springs.  Below is a short video that shows how to change the springs, and a short article, for your to print out and use as a guide when, or if, you do change your springs.

Tools:

1.   1 -   5mm allen wrench
2.   2 – 10 mm wrenches or socket wrenches
3.   2 – 13 mm wrenches or socket wrenches

a. With a 5 mm allen wrench and 10 mm socket wrench loosen the 4 bolts the keep the knee bar/calf cuff in place.  Just loosen them.  You don’t need to take the nuts completely off.

b. Slide the knee bar/calf cuff up and off the unit.

c. With 2 – 13 mm wrenches, loosen and remove the bolts that keep the spring/black brace onto the frame.  Remove the nut and slide out the bolt.  Perform this at both ends of the spring.

d. With the black braces still attached, pull the spring free from the frame at the top and bottom.

e.  With 2- 10 mm wrenches, loosen and remove the 2 – bolts that keep the black spring brace attached to the spring itself.  Each end of the spring has a black brace, and each brace has two bolts.  Loosen and remove them all.

f. Slide the spring out of the aluminum frame.

g. To install your new spring simply perform the above steps backwards.

h. Slide the new spring into the aluminum frame.

i. Reattach the black braces to both ends of the spring using the same bolts and nuts.

j. Reattach the black braces (top and bottom) to the frame, insert bolts and tighten the nuts.  Very tight!

k. Slide the knee bar/calf cuff back into the frame and tighten the 4 bolts.

That’s it.

Happy bocking.
