About this product
The Risunmotor RM800HD is a universal 4-piston hydraulic disc brake kit for front and rear application, designed for electric tricycles or high-power e-bikes. These black aluminum brakes feature a powerful 4-piston caliper and include a power cut-off function for enhanced safety. With hose lengths of 95cm for the front and 160cm for the rear, and an item weight of 1.2kg, this set provides strong and reliable braking for demanding electric vehicle applications.
Our take
If you're upgrading an electric trike or a high-power e-bike, the Risunmotor RM800HD 4-piston hydraulic disc brake kit offers a robust solution. The 4-piston design is a significant advantage, providing the powerful stopping force needed for heavier and faster electric vehicles. The integrated power cut-off function is a critical safety feature, ensuring the motor disengages when braking, which is essential for e-bikes. The longer hose lengths (95cm front, 160cm rear) indicate compatibility with a wide range of frame sizes and setups. At 1.2kg, they are substantial, but that's expected for heavy-duty brakes designed for this application.
