We thought the Gen 4 was going to be a fantastic motor, but now they are out of warranty we are being swamped with them! There is a few difficult technical issue to get over with calibration etc. But because Bosch put the PCB at the bottom of the motor, any significant amount of water will kill it dead! GAME OVER!Thanks for all your feedback @Bearing Man. Much appreciated!
What is your experience with the Bosch CX Gen 4 (BDU4xx, non-Smart) in terms of serviceability? Are we also looking at a high repairability percentage similar to Gen 2 motors?
The reason I bring this up is that a few eMTB manufacturers are still selling bike models with Bosch Gen 4 units (non smart) in their 2023 lines. This may be of interest to anyone looking for a Bosch powered bike that don't want to jump on the Smart-system bandwagon.
