Trails: We advocate for them, we build them, we maintain them. If you ride in Boulder County, you've seen our mark - from the Marshall Mesa system, to Picture Rock, to Little Raven, to Valmont, we've asked for & received new trail, improved upon trails, and maintained trails all around the area.  

Parties: Yes, we like to hang out, talk rides and trails, and adventures. We do big shindigs (like Thursday's Membership Party), smaller First Mondays, and a monthly happy hour for our Bike Patrol. We're not always about riding, but it's always about fun!

Rides: You ride, we ride. We host weekly Gurlz & BOSS rides, larger monthly Knobby Weekends, and the granddaddy of Boulder County rides, the fully supported Sufferfest/Caribou Classic with 150+ BMA members. We ride, you ride, let's ride together!
