4-PISTON BRAKING CONTROL
The 4-piston calipers provide stronger and more stable braking support than a standard 2-piston setup.
A good choice for heavier eBikes, faster rides, and riders who want better braking control.
2-PIN MOTOR CUT-OFF
The 2-pin connectors help interrupt motor power when the brake lever is activated, giving you better control while braking.
Please confirm your eBike uses a compatible 2-pin connector before ordering.
PRE-BLED AND READY TO INSTALL
The brakes are pre-filled with mineral oil to make installation easier.
Front hose: 1000mm
Rear hose: 1800mm
Professional installation is recommended if hose shortening, fitting replacement, or brake bleeding is required.
