What size kid's bike do i need?

This handy chart should show you the right bike for your child, based on age, height and wheel size (inches). Bikes with 12" wheels are generally balance bikes: with no pedals or cranks, they are designed to teach balance and control and are the perfect introduction for young children up to 90cm.

Kid's bike sizing guide:

Wheel Size 10'' - 12.5'' 14'' 16'' 18'' 20'' 24''
Rider Height (cm) 85 - 95 95 - 105 100 - 115 110 - 125 120 - 135 130 - 155
Age Range 1.5 - 3 3 - 4 4 - 6 6 - 7 7 - 9 9 and +

All little riders grow at different rates. So the best way of finding the right size bike for them is to look at models in their age range and then match their height to the right bike. As a rule, it’s best to get your child to sit on a potential new bike and to check that they can touch the ground with both feet.

The Mondraker Grommy 16 is a totally new way for young riders to have fun on two wheels – and learn essential skills with a smile like you’ve never seen before! It’s a cool kids’ balance bike with a punchy little motor and made from all the great materials, technology and know-how you expect from a Mondraker bike. Grommy transforms the humble balance bike, taking it to a whole new level.

Ideal for children between 5 and 8 years old, the Grommy 16 has a saddle height range of between 43 and 58cm. It will help your little ones gain balance and begin to manage a bike perfectly. Weighing in at only 8.5 kg thanks to its 6061 aluminum frame, its motor and battery allow for up to hour’s use at full speed. Of course, that doesn’t mean that the power can’t be easily controlled at all times.
