The Umit Spartan mountain bike is equipped with an aluminium frame and suspension fork which compensates for unevenness from the road. The boys' mountain bike is also equipped with 21 gears. These gears make it possible to easily drive on muddy roads. Also accelerating from a standstill or cycling at high speed is no problem. The fat tyres with deep profile complete the bike. The tyres provide optimal grip, even on unpaved roads.
