SEMBA was created to enhance, preserve, and promote existing mountain biking trails – while creating new opportunities, access, and experiences for all mountain bikers in the Eastern Sierra.

Our region spans along the Highway 395 corridor from Lone Pine in the south, to Bridgeport in the north.  Our members are diverse and encompass every aspect of mountain biking and off-road cycling.  We share one common thread – passion for riding bikes, and sharing the stoke with friends old and new.

Year-round, throughout our region, we host:

  • Trail days – maintain the old, build the new – SEMBA is working in partnership with the Town of Mammoth Lakes Trail Coordinator Joel Rathje, to maintain old and new trails in addition to Mammoth Mountains network.
  • Group rides -“fun-based” riding opportunities – all skill levels welcomed and encouraged, including women-only rides, bring-a-grom rides, overnight bikepacking outings, etc.
  • Social events – movie nights, “fun-raisers”, bike clinics, etc.  Hang out, drink beer, talk bikes.
  • Member meetings – working at the regional and local levels via committees to work with land managers to create, improve, and implement mountain biking plans, etc.  Be part of the solution.
  • Group trips – travel to mountain biking meccas all over the country.  We carpool and cost-share to make super memorable mountain bike vacations with friends.
  • Race Team – if going fast is your bag, we put on a variety of grassroots races and our team attends regional races.  Push yourself with friendly competition.
  • Winter Fat Biking Currently, fat bikes are not allowed to share the groomed winter trail network on the Inyo National Forest.  This includes ALL trails groomed for snowmobiles and nordic skiing.  We are diligently working with the U.S. Forest Service and the Town of Mammoth Lakes to change this.  In the meantime, it is our responsibility to educate the public about our passion, and foster a camaraderie and respect between all user groups.  Please help by staying off the groomed trails, and being an ambassador for the sport.  Contact us for more info, or join our Google Email Group to hear about snow conditions, grooming status, etc.  Fat Bike Mammoth is another great resource for legal riding opportunities in the area.
