Seven-speed gearing with a twist shifter lets young riders match resistance to hills or flat paths, while the front suspension fork and anti-slip tires help absorb bumps for steadier rides. The high carbon steel frame supports up to 220 lbs and works with a 63 x 23 x 40 in overall size to suit growing kids. Adjustable saddle height from 28.5-34.5 in and 38-40-in handlebar height help fit riders from 56-66 in tall. Non-slip handles, pedals, reflectors, bell and kickstand support everyday use and basic skills practice.
