- Class 1
- Montana does not use a statewide three-class framework; it defines electrically assisted bicycles as a single category generally limited to low-speed operation.
- Class 2
- Because Montana does not codify separate statewide Class 2 terminology, throttle-capable devices are regulated under the broader electrically assisted bicycle definition and local rules.
- Class 3
- Montana does not establish a distinct statewide Class 3 category; higher-speed models may be regulated differently and face stricter access limits.
- Helmet laws
- Montana has no broad statewide bicycle helmet mandate in state statute; local rules may apply.
- Age restrictions
- No clear statewide minimum age was identified for all electrically assisted bicycle operation in Montana statute; local restrictions may apply.
- Road access
- Qualifying e-bikes may use roads and bike lanes where bicycles are permitted.
- Trail access
- Trail access varies significantly by land manager in Montana (state, federal, and local); always follow posted route designations.
- Sidewalk rules
- Town codes regulate sidewalks; resort towns may restrict motorized bikes.
- Important notes
- Primary references: Mont. Code Ann. §§61-8-102, 61-8-608 (electrically assisted bicycle definitions and operation). USFS, BLM, and ski-town trail networks dominate access rules here. Educational summary only—not legal advice.
