Balance bicycle
From Wikipedia, the free encyclopedia
A balance bicycle is a training bicycle that helps the rider learn balance and steering. It has no pedals, no crankset and chain, and no training wheels. It can be a normal bicycle with pedals and related parts removed, or it can be purpose-built. It can have no brake, or it can have one or two hand-activated rim brakes.
To function properly, a balance bicycle must be small enough that the rider can walk the bicycle while sitting comfortably in the saddle, putting both feet flat on the ground.
Children as young as 18 months can learn to balance on a balance bicycle within a few hours' practice. The rider first walks the bike while standing over the saddle, then while sitting in the saddle. Eventually, the rider feels comfortable enough to run while riding the bicycle, then to lift both feet off the ground and glide.
