This easy to use Fun rider is guaranteed to offer hours of enjoyment and exercise for your child. In order to move, it uses a locomotion principle called cambering motion which causes it to move forward. All your child need do is a simple left/right motion with their legs and they will be surfing down the street at speeds of up to 12mph when mastered. There are no pedals, no chains and no batteries required for it to be used. It comes in 4 different colours and comes with tools that can be used to extend its size so that it can grow with your child. It is suitable for children aged from 4-14, with a maximum weight of 68kg and a minimum height of 3'3". A helmet, body padding and parental supervision is strongly recommended during use in order to minimize the risk of injury.
