ABOUT SDMB

Mission and Statement of Purpose

Sonoran Desert Mountain Bicyclists is a volunteer-driven 501(c)(3) non-profit organization devoted to the promotion of the sport of mountain bicycling, and view the sport as a vehicle to promote low impact outdoor recreation, conservation, and mountain bicycling opportunities that are environmentally and socially responsible. SDMB is dedicated to protecting and enhancing mountain bicycling opportunities through:

Providing fun, safe bicycling experiences and social events for the bicycling community, and at the same time using these events as an opportunity to educate and encourage riders. 

Promoting responsible riding, ethical behavior, and diversity among the mountain bicycling community through example, education and encouragement of riders.

Working in concert with land managers and owners to protect, improve, and to build sustainable trails and facilities to accommodate growth in the area.

Working with other user groups to ensure a quality trail experience for all users.

The Sonoran Desert Mountain Bicyclists educate, advocate, build and maintain sustainable trails for public access.

Code of Ethics

As members of Sonoran Desert Mountain Bicyclists, we represent the mountain biking community, and it is important that our external and internal relationships advance, rather than hinder, the image of mountain bikers. To that end, we ask that all club members agree to the following four principles:
