Mountain Biking

 Motor Assisted Bicycles: The Grand Junction BLM has determined that motor assisted bicycles (electric, gas or diesel) are "motorized vehicles." Use of motor assisted bicycles is only allowed on motorized trails. Please visit the motorized recreation pages for trail information.

Regulations found at 43 CFR 8340.0-5(a) define an “off road vehicle” as "...any motorized vehicle capable of, or designed for, travel on or immediately over land, water, or other natural terrain..." Furthermore, regulations found at 43 CFR 8342.1 direct the BLM to designate routes as either available for or not available for off road (motorized) vehicles.
Since electric assist bikes have a motor, they fit under the definition provided in 43 CFR 8340.0-5(a) as off road (motorized) vehicles. Thus, electric bikes are allowed only on routes designated for off road (motorized) vehicle use and prohibited from routes that have been designated only for non-off road (non-motorized) vehicle use. At this time, there is no other BLM guidance specific to managing electric assist bikes, so the Grand Junction Field Office is managing the use as motorized based on the rationale described above.
