These models are built around a very small adult frame with 26" wheels. As the child grows, the wheels can be swapped for 650B wheels, meaning the bike will fit your child for longer.

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.



‘F-Mount’ equipped bikes have integrated fittings for mud guards (some bikes require model specific mud guards), making fitting fast and simple.



Integrated mount on the chainstay to fit a MERIDA kickstand (or any commercial kickstand).



‘C-Mount’ equipped bikes have the fixing points for a rear rack already integrated (some bikes require model specific rear rack), making fitting fast, simple and reliable.
