We have a problem which is restricting us from setting up our multi-gear system. Our problem is that the heavy duty chain that passes through the Greenpower 14 t motor sprocket is not compatible with our bike sprockets. Due to this issue we unaware of how to effectively set up the multispeed gear system and were wondering if you could advise us on how to solve the issue. We were initially thinking of using just a motor to axle arrangement but now we are considering a layshaft. However, we do not know which method would be most beneficial and taking into consideration this is our first year with a multi speed system.
