Specs are for the stock bike as sold; check your own bike before you buy. This page covers the FX+ 1 and FX+ 1S on the newer FX+ 1 frame. They use Hyena's hub based e-system with 60 Nm of torque and a throttle, and the bike weighs about 50 lb. Older FX+ 2 and Dual Sport+ models use different parts, so match yours before you order. For hub drives in general, see hub motors and e-bike motor systems explained.
Electrical parts on this list must match this exact model and are fitted at the external plugs or by a pro. Never open the battery, controller, motor or display. Battery removal is dealer work on this bike.
