The motor cut-off for hydraulic brakes is an essential safety device for any electric bike. It automatically cuts off the motor power as soon as the brake lever is activated, ensuring effective and safe braking.
Compatible with most hydraulic systems from Shimano, Tektro, Magura, SRAM, etc., this cut-off is easily installed without modifying the existing brakes. It ensures optimal motor control and improves driving safety, especially on powerful models or those with high assistance.
Key Features
-
Enhanced safety: instantly cuts off the motor when braking.
-
Universal compatibility: works with most hydraulic brakes (Shimano, Tektro, Magura, SRAM, etc.).
-
Simple installation: sensor to be glued to the lever + magnet to be fixed on the moving part.
-
Precise operation: reliable activation thanks to a stable magnetic field.
-
Protection of the motor and cyclist: prevents unintentional acceleration during braking.
