Mongoose Legion Freestyle BMX Sizing Chart
Mongoose have been manufacturing performance bicycles since 1974. Founded in a So Cal garage, Mongoose Bikes has always been an innovator. From their current crop of BMX, Mountain and pavement bikes, Mongoose is still synonymous with bicycle performance.
Mongoose designers aren't wasting time watching reruns on ESPN2 - they're out testing their new designs at the park, on the track and on the hill. It's what drives them to cook things up like their Front Porch head tube, which lets you fine-tune the handling on their Black Diamond series mountain bikes, or Freedrive suspension technology, which eliminates pedal bob and gives you super-efficient full suspension. Experience that ultimately leads to better bikes for you. Mongoose bicycles don't just push the limits. They set new ones.
