Shifting Gears
Has anyone tried using an internally-geared hub like the Nexus-7 with a bikemotor? I have read max torque values for some of these hubs but am not sure if they could handle a 50-70cc two stroke engine output... Some real world tests would be more useful than specs on paper. Also the max-torque specs for geared hubs are (I assume) for very low rpm consistent with pedaling speeds, So if the geared hub is mounted like a jackshaft in the frame and not in the wheel and spun at a higher rpm(lower torque), Would it be able to handle the overall power better? Would the higher rpm wear the hub out faster? Maybe someone out there has some experiences they can share? Sure would be great to have a 7-speed tranny.
