Hello from Houston
Hi, this is the first time i become a member of a forum, and well i have a question hopefully someone could help me with.
i've seen some bikes that have a chain connected to a metal sprocket on the back weel. but i have also seen other bikes with what looks to be a rubber band, (kind of like a alternator band on a car motor) and this is connected to something that does the same function as a metal sprocket but is about 3-4 time bigger in diameter.
any help would be a appreciated.
