Specs are for the stock bike as sold; check your own bike before you buy. This page covers the original Engwe Engine Pro full suspension folding fat tire bike. The Engine Pro 2.0 is a different bike with its own battery, so don't mix the two lists. Battery packs differ between production versions, so read your battery label before you order. The Engine Pro was out of stock when read.
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.
