The X-Bike fits, feels & rides just like a real bicycle. So much so, it's officially endorsed by the UCI. Riding the X-Bike 'feels' the same as riding an actual road or mountain bike outdoors, especially while performing standing climbs or sprints. This elusive 'feel' is made possible by articulating Trixter's patent-pending X-Bike handlebars side-to-side against adjustable resistance; fully engaging your upper-body, legs, core abdominal & stabilizer musculature. The movement is totally natural & the fitness benefits are irrefutable.
