Ridgeback Dimension 24 2023 - Junior Bike
The Ridgeback Dimension 24 is built to be lightweight, fun and adaptable and is perfect for those 140-150cm tall.
The Dimension 24 focuses on being lightweight. A light bike is really important for kids because heavier bikes are harder to handle, turn and pick up. On smoother roads, paths and trails, a lighter bike makes for a more enjoyable experience and bigger smiles all-round.
The Dimension 24 features an aluminium frame and fork which is not only light, but also durable and built to last. These are real bikes, not toys and will happily get multiple kids smiling and riding.
There's also easy to use seven-speed Shimano gearing, which is ideal for flatter environments. The single chainring setup saves weight and also makes it easier to find the right gear.
The gear shifter is similar to that found on regular bikes, making it easy to transfer the skill as your children move onto adult bikes.
The Dimension 24 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 whatever the terrain.
