Kids Bikes - From Walker To Rider
Kids bikes range from the starter balance bike to help the little ones get the hang of being on two wheels instead of two feet, to small versions of road bikes and mountain bikes.
Balance bikes - also called walker bikes - don't have any mechanical parts or gears that complicate matters, all they have is two wheels and often a front brake to get the kids used to riding, simply using their feet as propulsion to get the hang of 'riding' the bike.
Bikes of all Types but smaller...
When they are able to ride a bike you can buy road bikes and mountain bikes for them which are the same as full size bikes in terms of mechanics, just smaller. The geometry is designed to suit smaller people but you can still buy top end components and models from most manufacturers.
