The Bainbridge Island Mountain Biking Club supports the Gear Grinders, the Island’s coed middle and high school level mountain bike teams. We raise funds for equipment, rider and coach training and league fees. The Club also supports the growth of mountain biking on Bainbridge Island. We propose and support new mountain biking facilities, such as Jay’s Pump Track at Battle Point. Our volunteers are major contributors to the building and maintaining of all the trails on Bainbridge Island.
