The Pedalwise team started this page from official manuals, support pages and repair videos. Fixed this yourself, or spotted something wrong? Help improve it.

Specs are for the stock bike as sold; check your own bike before you buy. This page covers the Fiido C11 and C11 Pro city commuters. Fiido sells the same tire, tube, brake pads, battery and charger for both; the specs below are for the C11, and the display listed is for the C11 only. Fiido parts are non-universal and not returnable once shipped unless faulty, so confirm fit with Fiido support before you order.

Electrical parts on this list must match this exact model, and they are fitted at the external plugs or by a pro. Never open the battery, controller, motor or display. For charging trouble, start with battery won't charge and e-bike battery care.
