Durable aluminium frame. For 24" and 20" wheels with replaceable dropout hanger and equipped with mounts for rack, mudguards and kickstand. 16" or 12" wheel options are optimised for the use with training wheels.

The specific demands on childrens' components make them differ a lot from adult components. Not only that kids are smaller, but also do not have the same strength in their hands, for example, when it comes to braking. That's why we have chosen specific components to ensure that our youngest cyclists are able to use their bikes safely and comfortably and make them easy to handle in any situation.

Our MATTS J.+ bikes feature not just the well-proven weight and geometry optimised frame but are also designed around a lightweight, rigid fork combined with 20" or 24" 'plus' tyres for extra grip and comfort. The result, no unnecessary weight, simple, stylish and hugely effective.

Durable aluminium frame for 16" wheels, optimized for the use with training wheels.

Many of our bikes feature rigid forks. This helps to keep the weight down, which is a big advantage for much lighter riders. Gears are also kept to a minimum, avoiding confusion for young riders, as well as reducing weight.

All kids' bike frames are made with the same 6061 lightweight aluminium we use in our adult bikes; we don't cut any corners. They're also painted and lacquered in the same way, so the bikes can still look great even after a few tough knocks.




We use a minimum of 6061 aluminium. The pay back is that it’s possible to make lighter and more advanced frames. We use an additional heat treatment and double-butted wall thicknesses to produce light and stiff frames.
