Now more motorcycle like! (I made this without knowing there was already one, lol)

Yes, you have motorcycle wheel/feet which you use to drive. Jam your sword hands into each other!

This ver makes the cycle more stable and doesnt need extra force to push you. Slightly more control over your bike.

nice modzorz

Looks rather like my mod...
But how well do they balance?

They balance pretty well. i can drive slightly off to side, or tilt over and try sliding under their strait forward joust. Unbalancing might be a decent way to win.

there has been a couple of these, but more cannot be a bad thing, right?

i didnt realize there was one until after. you may use idea on how i arranged joints so it doesnt break apart/unbalance.
I know i started with one like urs, but it kept sliding apart and what not.
