Electric bicycles-regulation.

Wyoming's SF 81 defines electric bicycles into three classes with specific speed limits: Class 1 (20 mph assist only while pedaling), Class 2 (20 mph without pedaling), and Class 3 (28 mph assist only while pedaling). The bill requires manufacturers to affix permanent labels showing class, speed, and motor wattage on all e-bikes, prohibits modifications without relabeling, and clarifies e-bikes are not motor vehicles (so they don’t require licenses or registration). It also sets operational rules: Class 3 bikes are restricted on some paths, require helmets for minors, and must have speedometers, while all e-bikes must meet federal safety standards and disengage motors when braking or not pedaling. The law directly affects e-bike manufacturers, riders, and local authorities managing bicycle paths.
