Bosch eBike Systems Repair FAQ

What Bosch motor systems do you service?

All generations - Classic+, Active Line, Active Line Plus, Performance Line, Performance Line CX, Cargo Line, Speed, and the current Smart System.

My display shows Error 500 - what does it mean?

Error 500 is a general drive unit fault, usually communication between the motor and display. We run diagnostics on-site to pinpoint the cause.

Can you update Bosch firmware?

Yes - via Bosch DiagnosticTool or the eBike Flow app depending on your bike's generation. Firmware updates are included in any service call.

Do you service Bosch mid-drive motors themselves?

We diagnose, inspect, and handle motor mount and bearing service. Full internal motor rebuilds are done by Bosch service centers, and we can coordinate that shipment for you.

How much for a Bosch diagnostic?

$30 standalone or included with any tune-up. You get a full error-code readout, firmware check, and health report.
