• 【4-Piston Powerful Braking】ZTZ hydraulic brake calipers feature 4 oil pressure pistons, providing superior braking capacity compared to 2 pistons, ensuring easier and safer braking. Pre-bled with eco-friendly mineral oil, these brakes are ready for action. Avoid squeezing the brake lever when the caliper is not clamped on the protective pad or brake rotor to prevent oil leakage
• 【Tailored for E-bikes/Electric Scooters】ZTZ hydraulic brake system is equipped with a brake automatic power-off sensor and 2-pin connectors. The sensor receives the braking signal, cutting off the motor's power output for a quick and safe braking experience. The automatic power-off feature enhances control and responsiveness
