Where the smile is the unit


We know that kids want to have fun precisely like us adults. That the key to their happiness is to allow them to reach the same hills, to ride down the same trail of the deepest forest together with us. So we developed bikes to wipe out their lack of strength and height: we found out, not only 27,5" but even 29" wheels are comfortable and easy to handle for young riders if you build the right frame. Add the convenience of a single chainring, cassette with a huge range and start counting the smiles. Big wheels = big smiles.
