Default Re: Advantages/disatvantage Of Friction Drive

THe only advantage to Friction drive over chain drive that I do not see already mentioned is that with a friction drive kit you can completely disengage the roller bar from the wheel when you are pedaling and not using the engine.
With a chain drive it is obviously always connected and thus always producing drag, making use of the bike without the engine running extremely difficult.
And dont let anyone tell you these engines do not produce a significant amount of drag. They do. So if you plan to use legpower from time to time, do not go with a chain drive. You will regret it.
