Bosch Speedsensor

The Bosch Speed Sensor ensures an extremely accurate recording of the electric bicycle's riding data. This reliable component transmits the exact cycling speed directly to the motor system, resulting in a perfectly metered and natural pedal assistance. Thanks to the precise measurements, the system responds instantly to any change in speed for a stable riding experience.

Material and construction
The sensor housing is made from a sturdy and impact-resistant plastic material that provides optimal protection for the internal electronics. The construction is fully waterproof and dustproof, allowing the sensor to continue functioning undisturbed during rides in pouring rain or on muddy paths. The flexible cable jacket protects the internal data wires against kinking and breaking, which significantly benefits overall durability.

Extra features and finish
This essential e-bike component is equipped with an original Bosch connector that guarantees interference-free signal transmission to the drive unit. The finish is fully focused on a stable mount near the rear wheel, keeping the sensor vibration-free. The light weight and the inconspicuous black design ensure that the sensor blends discreetly into the frame design of the bicycle.

Fits on
The Bosch speed sensor is specifically designed for Bosch eBike System 2 (BES2) and Classic+ drive systems with hub gears or derailleur systems. This specific variant features a cable length from 415 millimeters up to 1610 millimeters, depending on the chosen version, so there is always a suitable length for different frame builds.

Does not fit on
Bosch Smart System motor systems.

How can I check this
- If your display or handlebar control is black and white, you have an eBike System 2 or Classic+. When it is a color display, you have a Smart System and it does not fit.
-If you can connect the system to your phone, you also have the Smart System and it does not fit.

The spoke magnet is not included. If it is also required, it must be purchased separately.

The mounting takes place on the frame via a fitting bracket, where the sensor functions in combination with a spoke magnet on the rear wheel.
