alright, heres my crazy bike idea that ive been pondering for a while: i wanna get track wheel with a freewheel on each side and set it up double drive, with an easy gear on the left and a hard gear on the right. that way, you could pedal forward on a really high gearing and skid on a super low easy gearing, because the right side freewheel would engage when pedaling forward and the left side freewheel would engage when pedaling backward.. plus it'd look sweet. would it work?
