When your motor cuts off during riding, one possible reason could be the brake power cutoff sensor, which is located on the brake. It's always a good idea to double-check the sensor and consult the manufacturer's documentation if you experience any problems with your e-bike.
A brake power cutoff sensor is a safety feature commonly found on electric bikes (e-bikes). Its purpose is to cut off the power to the motor when the brakes are applied. When you squeeze the brake levers on your e-bike, the brake power cutoff sensor detects this action and temporarily interrupts the electric motor's power supply. This feature enhances safety by ensuring that the motor stops assisting or providing power when you're actively braking.
The brake power cutoff sensor is an important safety mechanism that helps prevent accidents and allows the rider to maintain control over the bike. It's a standard feature in many e-bikes to comply with safety regulations and standards.
