About PUMP

Since 1988, PUMP has been Portland’s premier mountain bike club. We are a rider-oriented, volunteer powered, mountain bike organization. Our goal is to promote, protect and enhance mountain biking in Oregon and SW Washington.

PUMP strives to educate the public about the benefits of mountain biking, to expand and develop trails in the Portland area, and to offer fun mountain bike rides for all abilities.

PUMP is a 501 (3)(c) non-proffit corporation and is also an IMBA affiliated club.
