Ridgeback Dimension 20

Ridgeback Dimension 20

    The Ridgeback Dimension 20 is a lightweight and versatile bike, perfect for kids from 120-140cm tall.

    Featuring a lightweight aluminium frame and fork, the Dimension 20 is easy for kids to handle while also being robust. These are real bikes, not toys and will happily get multiple kids smiling and riding.

    Shimano gears are smooth and reliable, offering seven speeds ideal for flatter terrain. The single chainring setup saves weight and also makes it easier to find the right gear.

    The Dimension 20 is equipped with strong wheels featuring 32 spokes and quick-release skewers. Lightly treaded tyres make this bike adaptable for use on road and across gravel tracks or smooth forest trails.

    A short stem and riser handlebar give confident handling and a comfortable position wherever you ride.
