We have compiled important tools that may be needed for the assembly of various e-bike tuning tools. In many cases, these are special tools that are not available in stores - or at least only with difficulty (especially the Spider Tool). If no special tool is listed for your favorite e-bike tuning product in connection with your e-bike motor, you will only need standard tools for installation. By the way: Special tools are mainly needed when you want to optimize Bosch motors. Namely, whenever you want to attach a module to the motor or want to use a different chainring.
