2. Hydraulic Disc Brakes

With higher speeds and increasing weight, ebikes require a powerful and controllable braking system to make sure a safe stop, allowing riders to brake accurately in any situation at different speeds, terrains, and riding habits, ensuring their own and others' safety. Hydraulic Disc brakes are typically the preferred choice for all high-performance ebikes, as they transfer force from the brake lever to the brake pads through hydraulic oil, providing stronger stop function and more precise control. Meanwhile, hydraulic disc brakes require less maintenance and adjustment, making them often the best choice for mountain and road bikes.

750W rear hub motor paired with hydraulic disc brakes make a premium power and braking system for SF20H.
