Developed as a learning toy, the Sonic Glide balance bike is designed to promote balance during movement. When pushing with one foot and then the other, your child can naturally and logically learn to balance without stabilisers or other balance aids. With its height adjustable saddle, sturdy steel frame and 10 puncture-free tyres, it's the perfect practice for young children learning to ride a bike for the first time. The steel frame bike comes with 1 gear. Comes with one year manufacturers' guarantee.
