I have put together a tricycle, but it only allows for a 4in sprocket on the axel. I have added a motor to the tricycle and do not get enough torque. The motor came with a 6in sprocket, which will not fit on the axil. My idea is to set it up so the chain goes from the motor 1in to the 6in to the 4in in one continuous loop. WILL this get me the torque I should be getting?
