30-50 mph push Rig and CAD of my skates

Terrablade - 26-5-2006 at 12:37 AM

This rig pushes the skater with control and braking power very easily at 30mph, it has 15,000 watt Etek motor, lots of power. Working on a Monowheel version below. Actual picture of the rig about 4 posts down.

Skates are off road hard core skates with 4 disc breaks and 200mm x 50mm wheels. They kite well, go down ski slopes, and with the skate pusher can crunch over pretty much anything. Ski boots give lots of power and support.





Below post shows existing rig and existing skates. 5 pairs made so far.

Looks good! Now are these actually for sale now?

Or, are you just producing some prototypes?

I used grass skis back in the early 80's at my local slope in NJ - It was good fun. Only thing was that the ski boots got really hot on summer days...

Hi Davinch,

Mostly prototype right now. 5 pairs made now. the length is modeled from grass skis as you mentioned. Definitely planning on going into production. I wanted to test them thoroughly for a year or so more. But so far its been great.

Looks like you are using a bit of a rocker. You'll have better luck kiteskating with all wheels running even or maybe even more pressure on the front and back wheels. The farther apart the load bearing wheels are, the better luck you'll have skating upwind.

good call I use fairly large rocker

ah I see what you mean Bob that makes the skate track more. Makes sense. but turning can be nice too no? I mean without having to step the skate.

Quick turning is far less important in kiteskating. More sailing than motorboating. Wheels setup for straight-line traction is the key even though that means step-turning when making tight turns (usually at the end of the sailing line). It'd be cool if your rocker was adjustable - reduce to zero for kiteskating.

Hi Bob,
I will look into being able to raise and lower the end wheels. I noticed when on the beach with about 20knt wind and 7 meter bullet that I was losing my line and had to step upwind occasionally. or is that normal to be dragged a bit twards the kite.

The ability to hold a line is directly related to the traction supplied by the outermost wheels. In fact, longer skates have the best results for speed and upwind sailing though sacrifice turning agility. You will greatly improve the performance of your skates in regards to kiteskating by making the rocker adjustable. I'm betting the more adjustments you make for kiteskating, the less use you'll have for the center wheels. A good kiteskate makes for a poor downhill skate (big wheels far apart) - difficult to make one skate work great for both sports. Try adjusting the front and back wheels so that it bends the rocker backward and let us know what happens.

will do I will try to get it into my final design

side not I was kite skating on the beach today and making really nice turns without having to lift the skates. I was jiving the kite and making nice tight round turns

Mabye the lose sand would allow a two whee skate to turn like that ? under 15ft radius about

get rid of the helmet visor, too much drag
