A torque arm is an essential safety upgrade for your e-bike, designed to prevent your wheel from coming loose or detaching during high-speed situations. It securely connects the motor or drivetrain to the frame, providing additional support and stability, especially when accelerating or braking forcefully. By distributing the rotational forces, the torque arm ensures your wheel stays firmly in place, reducing the risk of damage or accidents. With this simple yet effective component, you can ride with confidence, knowing that your e-bike's wheel is secure and protected.
