State guide
Montana
Montana updated its e-bike framework in 2023 with House Bill 261 and Senate Bill 342. The official Montana legislative materials I found show a three-class system, broad bicycle-equivalent access, and a later clarification that an electrically assisted bicycle with a 750-watt-or-less motor may be used anywhere a bicycle may be used.
Checked against official sources on October 4, 2026. Rules and links change; confirm with the office listed before you act.

- Three-class system
- Yes. Montana adopted the three-class system in 2023 through HB 261, and SB 342 in 2023 also amended 61-8-102, MCA, to confirm bicycle-equivalent access for qualifying electrically assisted bicycles.

- No statewide e-bike helmet requirement was found on the official Montana legislative pages reviewed.
- Where e-bikes may ride
- Montana law says an electrically assisted bicycle may generally be ridden, with the motor in operation, where human-powered bicycles are allowed, including streets, highways, roadways, bicycle lanes, and bicycle or shared-use paths; after notice and public hearing, a local authority or state agency may restrict Class 1 on a bicycle or shared-use path, and may prohibit Class 2 or 3 there; separate bicycle-on-sidewalk rules and local traffic-control devices also apply.
- License or registration
- Montana's 2023 legislation excludes electrically assisted bicycles from motor-vehicle treatment; no state registration or driver's license requirement was found on the official pages reviewed, and no e-bike insurance requirement was found there.

What to do next
- For paved shared-use paths, check the local or state manager's posted rules because Montana lets path authorities restrict classes differently.
- On sidewalks, review city-level rules and traffic-control signs before riding because Montana bicycle-on-sidewalk rules and local controls matter in practice.
