Q: What makes the 4-piston design better?
A: Four pistons provide superior stopping power compared to 2-piston systems, with more even pad pressure distribution for consistent, powerful braking on heavy e-bikes and electric motorcycles.
Q: How does the motor shut-off work?
A: The integrated sensor automatically cuts motor power when you apply the brakes, preventing power conflicts and ensuring safe, smooth stops.
Q: What rotor size should I choose?
A: Larger rotors (180mm-203mm) provide more stopping power for heavier bikes or steep terrain. We recommend 180mm front/160mm rear for most e-bikes, or 203mm front/180mm rear for electric motorcycles.
Q: Is professional installation required?
A: While experienced mechanics can install it themselves, we recommend professional installation to ensure proper bleeding, alignment, and safety testing.
Q: What brake pads do I need?
A: Replacement pads are VX851, VRX851, or VRS851 depending on your riding style (standard, resin, or sintered).
