E-bikes and speed pedelecs in Montana (2026)
Last reviewed: 9 October 2026
In short: Montana has one category, the electrically assisted bicycle, whose motor can propel it no faster than 20 mph; it counts as a bicycle, which is not a motor vehicle. Bicycles may be ridden on sidewalks: riders must yield to pedestrians, give an audible signal before passing and keep off sidewalks where signs prohibit it.
