Bosch speed sensor: compatibility
The speed sensor has been installed in Bosch e-bike motors since the first generation and is found in all Bosch e-bikes up to the second generation. This speed sensor was also installed in the next two generations of motors, from 2018 and 2020. However, a new Bosch Slim speed sensor, the Speedsensor (BDU3xx, BDU4xx), was also developed and installed. For the 2022 model year, there is also a new Bosch Slim speed sensor for the Smart System. Therefore, when placing your order, be sure to pay attention to your e-bike’s model year and compare the different product images. If you’re unsure, our customer service team will be happy to assist you.
INSTALLING THE BOSCH SPEED SENSOR ON YOUR E-BIKE:
To replace the speed sensor on your e-bike with a Classic Line motor, you must first remove the stone guard. It is attached to the motor housing with three screws. For Active and Performance motors, you need to loosen the crank using a crank puller for the gearshift. Next, remove the screws from the design cover on the motor housing and carefully remove the left side. The speed sensor connection should now be exposed in both cases. Carefully pull out the connector using needle-nose pliers. Be sure not to pull directly on the cable. Now install your new Bosch speed sensor in reverse order.
