E-bike laws vary by state and municipality. It is your responsibility to know and follow the class rules, speed limits, licensing and age requirements that apply where you ride.
Do not exceed the 450 lb maximum load. Do not modify the controller, motor or battery — doing so voids the warranty and may make the bike unsafe.
Charge batteries on a hard, non-flammable surface using only the supplied charger, and never leave them charging unattended overnight.
