Bottom line

The Hyper GoGo Challenger 12 is a children's electric motorcycle, not to be confused with their Cruiser 12, which is the same bike with a different "tank" and seat color. It's advertised for riders from 2'9" to 4'9", and parents say it fits kids aged three to seven. Children enjoy the motorcycle styling, complete with fake exhaust steam and an engine sound effect. It's a fun toy while it lasts, but there are many reports of electrical failures in the first year. Owners are split on how helpful customer support is, ultimately making the Challenger 12 a risky buy.
