It might be considered too powerful for road use, but that logic discounts the abundance of traction that road and commuter bikes have, on a high-friction surface, compared to mountain bikes, riding up loose climbs. Some hub motors boost their torque with internal gearboxes (typically an arrangement of planetary (epicyclic) gears in between the stator and the rotor), but since that adds weight, cost, mechanical complexity, and potential unreliability, many do not. Bigger torque brings an added problem: you need to be sure the rest of your wheel is strong enough to cope with the twisting forces a hub motor can deliver, particularly if you're converting something like an ordinary bicycle wheel into a powered wheel. The spokes on an electric bike are shorter and leave the hub at a tighter angle, which can stress them further. Suppose you mount an electric motor on the hub of a basic bike and switch on the power. Since you weigh quite a lot and there's plenty of friction between the tire

We give the option to select a torque arm with most of the hub motor kits. Our best motors like the GMAC and Grin All Axle hub have an integrated torque arm that is part of the axle design, while the more generic motors require after-market torque arms if there are concerns about axle spinout. design compromises that undermine some of the advantages of using hub motors in the first place. Torque We're so used to the idea of cars being, well, car-shaped, that we find any other body layout extraordinary. But there's no real reason why a car has to
