Electric-assist bikes have special braking requirements. With the extra weight and speed of the motor, electric bikes put a lot of pressure on the brake pads. Pro E-Bike disc brake pads are tuned to provide extra braking power and durability. They also offer constant modulation with low braking noise. WHEN TO USE: Designed to meet the specific needs of pedal-assist e-bikes, Pro E-Bike pads are ideal for both city and pedal-assist e-bikes.
