So, that is really exciting. I’m glad people are still using their brains out there. What does it use instead of a chain? Some sort of very strong,rubberized cable? Also with the bearings exposed like that,wouldn’t they get really gummed up all the time? And wouldn’t it be really hard to find parts? Hmmm. Have you heard of the bike with no chain? The pedals don’t rotate they are just big levers that go up and down.
