Designed by a dedicated team of fitness engineers with a consistent stream of feedback from enthusiasts, club owners, trainers and physical therapists, the Assault is truly the best-in-class fan bike available today. Built from the ground up, we started with a frame manufactured from full high-tensile steel that is sealed with a layer of industrial powder coating paint. To ensure durability and long periods of maintenance-free use, all moving parts employ sealed cartridge bearings.
