RFMBA encourages our members, partners, and trail users to participate in the BLM Colorado River Valley Field Office’s current public scoping process regarding potential expanded access for Class 1 e-mountain bikes on designated mountain bike trails

The BLM CRVFO is seeking public comments to allow Class 1 e-bikes on Designated Mountain Bike Trails within the field office.  The BLM CRVFO is preparing an environmental assessment (EA) that will address singletrack mountain bike trail opportunities for e-bike users within the CRVFO by assessing on which, if any, existing designated non-motorized mountain bike trails Class 1 e-bikes would be allowed.

Love trails?  Have a passion for mountain biking?  Join RFMBA’s ninth annual Seasonal Trail Crew, May to mid October!  Enquire for potential to start late or finish early.
