Product details

Please note: all of our bike models come with an EU standard brake setup. This will need to be reversed to comply with UK cycling standards.

Inspired by the adult model of the same name, the sporty Rockville is a children's mountain bike with extra class. This model works just as well on the bike path as it does on dirt tracks – its chunky tyres offer great grip on all sorts of terrain. Featuring a light aluminium frame which offers not only a robust design but also ultra child-friendly geometry; its strongly sloping top tube upper allows for super safe handling.


  • Very good gripping and easy-to-operate V-brakes for maximum control
  • Stable wheels with aluminum hollow chamber rims
  • pedals included in delivery
