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, again 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.
