The Ultra Nitro is a mountain bike to enjoy your adventures off-road as well. The large wheel dimension (29") gives the bike more speed, but makes maneuvers more difficult. It has 21 gears so you can adjust the intensity according to your needs, but also to be able to climb more challenging hills. The front suspension absorbs crashes from bumpy roads and makes the ride more comfortable and relaxing. Also, the disc brakes will give you better stopping and control.
