• An e-bike is defined as a “low-speed electric bicycle” whose assisted maximum speed on a paved level surface, when powered solely by such a motor, is less than 20 mph.
  • E-bike owners are required to be registered and pay a fee of $30 at any city hall satellite location or the state business registration unit in Honolulu. You must at least 18 years old to register.
  • Persons 15 years and older may operate an e-bike if it is registered to a household member. Helmets are required for anyone under the age of 16. 
  • E-bikes are allowed everywhere a bike is allowed, including bike paths


  • On federal, state, county and local trails, e-mountain bike (eMTB) access varies significantly.
  • Generally, any natural surface trail that is designated as open to both motorized and non-motorized uses is also open to eMTBs. 
  • eMTBs may not be allowed on trails managed for non-motorized activities. 
  • Do not ride your eMTB in areas where the local rules are unclear. Ride legally and only on authorized trails to show that mountain bikers are responsible trail users.
  • When in doubt, ask your local land manager about access to specific trails. Local land rules change frequently.


  • LOCAL: Consult your local land management agency.
  • STATE: The Hawaii Department of Land and Natural Resources has stated that eMTBs are not allowed on natural surface trails. Contact the department for the most up to date information. 
  • FEDERAL: As of August 29th 2019 all eBikes up to 750 watt can now access Federal Lands and natural parks anywhere a regular bicycle can access.  The one exception is National Forests, the forests are managed by the Department of Agriculture and these changes are not implemented yet on the forests.  Changes are happening to align all Federal land to the recent Order.   However, Hawaii has minimal federal lands where mountain biking is allowed.
