For almost 40 years, Mongoose has been in the dirt, on the trails, and off the ramps. Founded in 1974 in a Southern California garage, Mongoose has always been an aggressive brand with products that push the limits of what a rider can do. Designed for professional-level performance, the Mongoose Legion Mag Freestyle BMX Bike has all the strength and style you need in the bike park. The premium Mongoose Hi-Ten Steel BMX frame and fork features low-stance geometry to offer a durable, responsive ride with alloy rear U-brakes for secure stops. The 40x16T gearing with durable one-piece forged steel 170-millimeter cranks offer simple, single-speed riding. Cast aluminum mag wheels with sealed bearings will turn heads while the cable detangler allows for 360-degree handlebar spins. This bike ships ready to be assembled and features 20-inch wheels.
