Universal E-bike Hub Motor Torque Arm for Electric Bicycle Motor Kit
Product Description
Product View
Torque arms are used to prevent axle rotation in hub motors. When a hub motor is powered up running, for all the torque that the motor generates spinning a wheel forwards, there is an equal and opposite torque on the axle causing it to rotate backwards.
In most electric bicycle hub motors, the axle is machined with flats on either side which key into the dropout slot and provide some measure of support against rotation. In many cases this is sufficient.
However, in high power systems that generate a lot of torque, or in setups with weak dropouts, the forces present can exceed the material strength and pry the dropout open. When that happens, the axle will spin freely, wrapping and severing off the motor cables and potentially causing the wheel to fall right out of the bike. A torque arm is a separate piece of metal attached to the axle which can take this axle torque and transfer it further up the frame, thus relieving the dropout itself from taking all of the stresses.
This torque arm will help prevent the motor from coming loose from the fork (front) or frame (rear) and also prevent the slotted axle from bending or breaking your dropouts.
Additionally, these versatile torque arms can be installed inside the frame/fork or outside.
