Founded in 1974 in a Southern California garage, Mongoose has always been an innovator. From its first product - cast-magnesium MotoMag wheels - to its current lineup of BMX, Mountain and Pavement bikes, Mongoose is synonymous with bicycle performance. From wheels to frames was a logical progression, and complete bikes soon followed.

BMX Products made the first Mongoose bike in 1975. By 1976, the Mongoose was a top-seller. With more than 45 years of pedigree, Mongoose has perpetuated a legacy of invention and innovation, creating bikes for the best riding experience out there. Now available globally, Mongoose is more accessible than ever, inspiring a new generation to push their limits and explore new boundaries, whether hanging out, or going all out.
