Bosch Wheel Speed Sensor

No, this specific sensor is designed exclusively for Bosch e-bike systems equipped with the 'Smart System.' Please verify your bike's motor generation before purchasing to ensure compatibility.

This sensor features a cable length of 1700 mm. This length is typically sufficient for standard e-bike frame routing, but it is recommended to measure your current cable run to confirm it will reach your motor unit comfortably.

This sensor is a required component for the Bosch ABS system, but it does not function as an ABS system on its own. Your e-bike must already be equipped with the necessary ABS hardware and software integration for this sensor to provide the data required for anti-lock braking.

While the physical installation is straightforward, the Bosch Smart System often requires a software handshake or calibration through a dealer-level diagnostic tool after replacement. If you are not comfortable with e-bike electrical components, a professional shop visit is recommended to ensure the system recognizes the new sensor correctly.

The speed sensor provides the real-time data your motor controller needs to manage power delivery. If the sensor is faulty or disconnected, the system cannot accurately gauge your speed, which often results in the motor cutting power or defaulting to a safety mode.
