Do you need the troublesome chain tensioner if you are mounting a motor to a 21speed bike with a rear derailleur? I was thinking of just mounting the engine in the perfect spot so the motors engine will have just the right amount of slack, and the rear derailleur will provide the bike's chain with the correct slack automatically?
