● 14 codes documented
Bafang uses 14 fault codes on its electric bikes, shown on the display when the machine stops — among them 02, 03, 04, 05, 06. Each one points to a specific part: on this page you find them all, with what they mean.
How to read the code on the display
Every code below comes from a published source, with the manufacturer or motor system stated — never a generic table.
Write the code down before switching off: many machines clear it when unplugged, and without the code the fault has to be found from scratch.
