750 watts, three classes, and land-manager-specific access
A qualifying e-bike has a saddle, fully operable pedals, a motor no greater than 750 watts, and one of three statutory classes. For e-bikes offered for sale or distribution in Michigan, manufacturers and distributors must permanently label the class, top assisted speed, and motor wattage. State law sets added age and helmet rules for Class 3, while access varies by class and land manager.Michigan Legislature — MCL § 257.13e· Michigan Legislature — MCL § 257.662aSpot an error? →

Class 1
The statutory definition requires a seat or saddle, fully operable pedals, an electric motor no greater than 750 watts, and one of Michigan's three classes. Separately, a manufacturer or distributor offering an e-bike for sale or distribution in Michigan must permanently affix a label stating its class, top assisted speed, and motor wattage.Michigan Legislature — MCL § 257.13e· Michigan Legislature — MCL § 257.662aSpot an error? →
A Class 3 operator must be at least 14, and anyone under 18 who operates or rides as a passenger on one must wear a qualifying helmet. State law allows Class 3 on highway areas open to bicycles, subject to stated local exceptions; DNR does not allow Class 3 on state-managed trails.Michigan Legislature — MCL § 257.662a· Michigan DNR e-bike guidanceSpot an error? →
Exact fallback category unclear: MCL § 257.13e defines the devices that qualify as electric bicycles, and § 257.662a expressly says a modified device is not an electric bicycle if it no longer meets § 257.13e or its motor exceeds 750 watts. Those sections do not assign every over-limit device one automatic fallback category.

Age, license, registration, insurance, helmet
Minimum age
MCL § 257.662a bars an individual under 14 from operating a Class 3 e-bike, although a child under 14 may ride as a passenger on a Class 3 designed for passengers. The section imposes no class-specific minimum operating age on Class 1 or Class 2.Michigan Legislature — MCL § 257.662aSpot an error? →
Anyone under 18 who operates or rides as a passenger on a Class 3 e-bike must wear a properly fitted and fastened bicycle helmet meeting the federal standards named in MCL § 257.662a. That section imposes no class-specific helmet requirement on Class 1 or Class 2.Michigan Legislature — MCL § 257.662aSpot an error? →
Not under MCL § 257.662a's class-specific helmet rule: its Class 3 helmet mandate applies to an individual under 18, and the section imposes no class-specific helmet mandate on Class 1 or Class 2. Wear one anyway.Michigan Legislature — MCL § 257.662aSpot an error? →
04 / Where you can ride
Roads are broad; DNR trail access is class-specific
DNR-managed roads
MCL § 257.662a allows an electric bicycle on any part of a highway open to bicycles, including bicycle-only lanes and shoulders. A city that prohibits nonemergency motor vehicles and Mackinac Island State Park are statutory exceptions unless the named authority allows e-bikes.Michigan Legislature — MCL § 257.662aSpot an error? →
Statewide paths and trails
MCL § 257.662a allows Class 1 on paved or similar-surface linear trails and rail trails, subject to the responsible authority's power to regulate or prohibit it. Classes 2 and 3 need that authority's permission. No class may use a designated nonmotorized natural-surface trail unless the authority allows it, and these rules do not apply to congressionally authorized public trail systems.Michigan Legislature — MCL § 257.662aSpot an error? →
DNR-managed trails
Generally yes where traditional bicycles are allowed in state parks, recreation areas, and state forests. DNR lists exceptions for state game and wildlife areas, congressionally authorized trails such as the North Country Trail, and named pathways in Pigeon River Country.Michigan DNR e-bike guidance· Michigan DNR state-parks rules FAQSpot an error? →
MCL § 257.662a requires a qualifying helmet for a Class 3 operator or passenger who is under 18. Its class-specific helmet rule therefore does not require one at age 18 or older and does not impose one on Class 1 or Class 2; wearing one remains the safer choice.Michigan Legislature — MCL § 257.662aSpot an error? →
Is an over-powered or over-speed electric bike still an e-bike?
Not if it falls outside MCL § 257.13e's definition. That section caps the motor at 750 watts and defines the class-specific motor engagement and assisted-speed limits; § 257.662a expressly says a modified device is not an electric bicycle if it no longer meets § 257.13e or its motor exceeds 750 watts.Michigan Legislature — MCL § 257.13e· Michigan Legislature — MCL § 257.662aSpot an error? →
