Kids bikes from Trek & Whyte are designed purposely to give children confidence with quality parts and simple hybrid frame designs. As their skills and confidence develop with an interest in more technical terrain, then a kids mountain bike with front suspension and knobbly tyres could be an ideal choice. Kids & junior sizing is based on wheel size with age as a guide. Height plays an important part in sizing.
