If you're serious about BMX and not satisfied with an entry-level bike, the Mongoose Legion L100 is definitely worth a look. This model isn’t just for getting started – it’s a full-fledged freestyle BMX that’s ready for the park, the streets, or the dirt jumps.
The frame and fork are made entirely of 4130 CrMo steel – the go-to material for pro-level bikes. It’s strong, yet flexible, and light enough to stay controllable in the air. The 21” top tube is especially ideal for taller riders.
The drivetrain is built for those beyond the beginner stage: a 175 mm two-piece CrMo crankset, 25T sprocket, and mid bottom bracket ensure that every pedal stroke delivers power efficiently. The rear cassette hub features a 9T driver, while the front hub uses a 3/8” axle – meaning the rear is built tougher, as it should be.
It rolls on 20” x 2.4” tires, mounted on double-wall aluminum rims with 36 spokes – not just for style, but to handle serious riding. A 4-piece CrMo handlebar, 50 mm stem, and integrated headset provide precise steering, and the U-brake is there when you need it, without getting in the way during tricks.
The Legion L100 is made for those who aren’t just dabbling – they know exactly what they want from a BMX. Durable, technical, and built right from top to bottom.
