Bike size for child

Postby Robin » 30 Jan 2009, 7:02pm

We want to buy a bike for a grandson's birthday, but as a surprise. So he can't be with us to try it for size. We plan to get a road bike not a mountain bike or racer. Is there a way to establish the right size if we find his height or inside leg measurement?

Have a look at They have quite good tables for what should fit. And these are very good bikes.

+1 for Islabikes. We have a drop bar Luath 26 (among others), and couldn't be happier. The company also offer a 14 day money-back guarantee, so in the unlikely event the size is wrong you can easily exchange. Kevin

Sizing a bike - suppose it needs to be bought second-hand.

With the saddle in its lowest practical position (not obvious with some suspension-equipped models), the balls of both feet should be able to touch level ground. By arranging various adjustable parts, the distance between the nose of the saddle and the back of the clamped part of the handlebars should be the same as from the elbow to the fingertips of the prospective rider.

Some off-road style brake levers can be set to suit the hand movement available. A few gears can be useful to teach a child about riding up & down hills.

Other than that, choosing a favourite colour of bike will encourage it to be ridden. Remember that children grow and that the saddle will need to be raised from time to time.

All the best, Punk_shore :P
