I have been told that Chain Drive Systems are not as efficient as hub motors because the motor drives via chains?
A. This is a ‘twist’ on the facts. The gears will cause a loss of ONLY approximately 1%. However the gain in motor efficiency (and other components) more than compensates for this since the motor is always able to be driven at its most effective speed. So OVERALL efficiency is far better. Net gain can be as high as 15% over hub motors.
