Bosch eBike Error Codes (Full Codes)

Fixing error codes on your Bosch ebike system can be simple. Sometimes all that is required is to restart the system. But on some occasions, you might need to bring it to your Bosch dealer.

Bosch Error Monitoring

The components of the Bosch system are continuously and automatically monitored. This means when an error is detected, it will automatically show up on the text indicator.

Some errors will shut off the drive unit. If this happens, you can still travel without motor assistance at any time.

Some Bosch error codes are easy to fix and can be performed yourself. However, troubleshooting actions labeled “contact your Bosch eBike dealer” should not be performed.

Here is the complete list of Bosch ebike error codes. I hope you find it helpful.
