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-grade performance, the Mongoose Legion L100 Boy’s Freestyle BMX Bike has classic style with upgraded components designed for the bike park. The Mongoose full 4130 chromoly steel BMX frame with an integrated headset features removable brake mounts, just like the pros. The top tube measures 21 inches long and 36-hole alloy double-wall rims keep the high volume 2.4-inch wheels true and rolling smoothly. Micro drive 25x9T gearing with cassette driver and a durable two-piece tubular Cromo 175-millimeter cranks are attached to an eight-spline spindle with a sealed mid-bottom bracket. Dependable Mongoose full 4130 chromoly steel fork and chromoly steel 8.75-inch bars are attached to the top loader with a strong, 50-millimeter stem. A rear alloy u-brake with alloy brake levers offers quick, crisp stops. This bike ships ready to be assembled and features 20-inch wheels.
