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:

To Ride Responsibly

We will follow the IMBA Rules of the Trail; we will be courteous and respectful toward other users, recognizing that they, too, have a right to enjoy the trails.

To Represent Ourselves Professionally

Disagreement is healthy; conflict is sometimes necessary to resolve problems. When discussing access issues, whether at public meetings or in private, we shall strive to keep the discussion based on facts and not allow ourselves to be drawn into emotional, negative responses. We will keep to the moral high ground.

To Share and to Teach

Whether it is riding a technical obstacle or organizing a work party, the more we share our skills and knowledge, the better we all can benefit.

To Respect One Another

The effectiveness and survival of the Sonoran Desert Mountain Bicyclists depends on members working together. We will operate within the framework of the Bylaws and, in addition, always:

  • Treat one another with dignity and respect.
  • Keep principles before personalities in our discussions. When we disagree, we will focus on the “what” of the issue, not the “who.” (In other words, we will check our ego at the door.
