500w_Of_Power
100 mW
Hi, I'm building a 1500w e-bike on 48v and the dropouts are aluminum, they just barely go over the axle. I was thinking of machining some 1/4in 304 stainless steel from SendCutSend to make extended dropouts, then adding a torque arm. I would bolt them on, and use JB Weld Steel epoxy for added strength. You can see my cardboard and paper mock-ups. Is this a good idea, or should I look for a steel frame?
