That's pretty cool but I don't think it could take the stresses put on a bike tire during high speed cornering not to mention there is nothing on the side to put on the ground in a curve. But I'm no Engineer. Always wanted to drive a train though.
Seems it would not wear out on a bile so i dont think they will. but if it can flex a 3000 car then it should work great on a bike. they could make it with a rounded tread
