Mongoose BMX Bikes

In 1974, Skip Hess developed the cast-magnesium MotoMag wheel in his garage as a way to make BMX bikes more durable. This led him to found BMX Products, Inc., which made the first Mongoose bike in 1975. By 1976 it was a top-seller. Mongoose would become known for innovative BMX designs and world-class BMX race teams. The very first BMX bike we sold here at Alans BMX was the Mongoose Supergoose in late 1980. Today Mongoose completes a great value and you know you have 40+ years of heritage behind the brand.
