Put together a free error code search tool for Bosch, Shimano, Bafang etc. — would appreciate some feedback.
Hi all,
Decided it was time to bridge a gap and make diagnosing E-bike issues, error codes etc a shed load easier. Gone are the days of having no mobile signal and trying to zoom in on a manufacturer service PDF on your phone.
I've developed a quick web tool to search 500+ e-bike error codes in plain English (covers Bosch Smart System & classic, Shimano EP8/Steps, Bafang, Brose, Yamaha/Giant, Mahle, etc).
It gives you the actual root cause, what to check with a multimeter (hall sensors, magnet gaps, pin voltages), and whether it’s a quick fix or needs dealer software. It also works offline once you load it so you can still use it out on the trail in dead zones.
Free to use here if it helps anyone out:

Continually adding to it weekly — if anyone spots any missing codes or weird glitch codes you’ve run into on your own bikes, let me know in the comments and I’ll get them added into the database!
