As of October 2017, state law in Michigan has recently changed with regards to electric bikes (aka eBikes). It’s much more clear where they are allowed on the roads and trails.
What is the definition of an electric bike? There are three classes based on their operation and speed. Generally speaking, all three are treated like bicycles but their use on trails is regulated based on the class.
|Class I||Class II||Class III|
|Must have seat and operating bicycle pedals||Yes||Yes||Yes|
|Maximum motor power||750 watts||750 watts||750 watts|
|Motor only assists pedaling||Yes||No||Yes|
|Maximum speed for motor operation||20 MPH||20 MPH||28 MPH|
|Minimum operator age||None||None||14|
|Helmet required||No||No||Ages 14-18|
|Allowed on roadways, bike lanes, shoulders, and sidewalks||Yes||Yes||Yes|
|Allowed on linear paved/gravel trails||Yes, but can be regulated or prohibited||No, but can be authorized||No, but can be authorized|
|Allowed on non-motorized natural surface trail||No, but can be authorized||No, but can be authorized||No, but can be authorized|
Electric bicycle use on trails can be regulated by the local authority after holding a public meeting.
Electric bicycles are generally not allowed on Mackinaw Island.
Bicycles fitted with internal combustion motors are not electric bicycles.
