JACKSON, Wyo. — Electronic bicycles have gained popularity among commuters and outdoor recreationists alike. But the vehicles have presented a bit of a conundrum to federal land managers: are they motorized vehicles, or just bikes?

The US Forest Service announced today that e-bikes are considered motorized vehicles and will be allowed everywhere motors are allowed.

“The USDA Forest Service considers e-bikes as motorized vehicles and therefore does not allow their use on non-motorized National Forest System roads and trails,” USFS said in a press release.

“The Forest Service encourages e-bike riders to consult their local National Forest or Grassland’s motor vehicle use map to ensure they’re riding on an approved motorized-use roads or trails and to exercise caution when traveling among other motor vehicles.”
