Bicycle Sizing Chart

If the bike is for a child, you will need a bike that will last as long as possible by providing plenty of 'growing room', but at the same time, not being dangerous because the bike is too big.

Bikes for children are generally grouped into age categories based on the average size of a child at a specific age. However this is not etched in granite and there is nothing that says you must buy a bike of a particular size for a child of a specific age. If the child is comfortable and not too stretched; they can turn the handlebars safely, reach and operate the brake levers and touch the floor with their tip-toes, then there is nothing to prevent you from selecting a bike in a bigger (or smaller) age category.

First bikes or pavement bikes are 12" wheel for average ages 3 to 5. Once a child has learned to ride without stabilizers they can move up to a 16" wheel cycle.

26" wheel bikes are usually offered in various frame sizes. This offers the benefit of being able to put a child onto a bigger wheeled bike if they are confident riders.

Once riding a 26" wheel bike, then size determined by the frame size. The size of frame is generally measured from the centre of the chain set to the point where the seat post is inserted into the frame.
