This page lists the common replacement parts for the NIU KQi3 Pro, KQi3 Sport and KQi3 Max. Specs are for the stock scooters as sold; check your own scooter before you buy. All three use 9.5-inch wheels and the same NIU tire listing; brakes and batteries differ.

Chargers and batteries on this list must match this exact model, and they are fitted at the external charge plug 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.
