Capteur Vitesse Électrique Bosch Aimant Review

Sooner or later all these fixes will no longer work and you just have to replace the speed sensor on your Boschh cx performance line like I did. Make sure you buy the correct crank puller. I used the universal one from ParkTool. Removing the motor and replacing the sensor wasn't difficult, although it did take a little time. If you're clumsy like me, an hour at the most. That's all. Since then there hasn't been a single error code 503. I also use a Speedbox 3.0 chip. There are no problems there
