Don't understand 3 chain wheel. I have been looking at a Cyclone kit for use on a recumbent bike. Comfortable but terrible at hill climbing. What do you mean by 3 chain wheel?
My recumbent has a 3 sprocket front crank hub and 7 gear rear cassette, 21 speeds, and I was thinking of getting rid of the 3 front sprockets and going with a freewheeling single crank sprocket. The Cyclone motor has the power sprocket on the motor and a tension sprocket to bend the chain around the motor drive sprocket so what is meant by 3 chain wheel?
