Overview
About this bike
Breaking the barrier to racing BMX shouldn't cost an arm and a leg. Designed to be the perfect introduction into the world of racing, the Mach One is built to suit every need. It features a light and strong 6061 aluminum frame with a steel fork and internal sealed headset bearings. Modern touches like the GT Power Series 3-piece crank, top-load stem, and integrated saddle/stem combo make it a capable rig.
