There's never been as many choices for the kids of today. Our guide will tell you what's available for children of different age groups, from 3 to 12 yrs old. It will tell you what to look for, what to buy, and more importantly, what not to buy!


Which size bike does my child require?
Children's bikes are generally measured by wheel size, rather than by frame size. Remember children do grow very quickly and you need to take this into consideration when buying a kids bike, However, if you buy a bike that is simply too big for your child, you will compromise your child's safety, and ultimately discourage your child from cycling.
