Strange thread? Well, it's amazing what useless stuff you learn when you've got nothing better to do, so you guys got any?
I bike a lot, everytime I go to the store and that is quite often, so natrually I got pretty bored... So I gradually started learning to bike without my hands on the handles, I can now bike indefinitly without hands as long as the road remains relativly straight and there are no turns sharper than 45 degrees, pretty sure I could keep going for several miles/km
No practical use for that at all, aside from being a showoff and having something to do when going to buy food and back.
