Product Description

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.


  • reliable 7-speed Shimano transmission with smooth-running Shimano Revo Shift rotary handles
  • Very good gripping and easy-to-operate V-brakes for maximum control
  • light 7005 aluminium frame with geometry suitable for children
  • Stable wheels with aluminum hollow chamber rims
  • pedals included in delivery

Good day. The bike is OK for the price and pleases our son. Once set up, everything is fine. Sitting position is quite short, so the child should not be too tall. Weight as indicated just a bit heavy.

Guten Tag. Das Bike ist OK für den Preis und usnerem Sohn gefällts. Einmal aufgebaut ist alles gut. Sitzposition ist recht kurz, so dass das Kind nicht zu groß sein sollte. Gewicht wie angegeben halt etwas schwer.
