The dimension 20 — lightweight fun for the next big adventure

Easy‐pedal cranks — our pedal cranks are ergonomically correct, proportional to the child's leg length. They also place the pedals closer to the bike's centre so that children can pedal as smoothly and naturally as possible.

Smaller grips — our handlebars and grips are narrower diameter so they fit small hands better, for confidence and control as well as better ability to reach the brakes safely.

Faster tyres ‐ special edition nutrak by vee speedsters with puncture resistantance.

Lowered frames — our frames are lower where it counts, making it easier to get on and off and increasing clearance for greater confidence.

Steering limiter — to help prevent falls when learning to co‐ordinate pedalling and cornering, the steering has a limit stop that helps avoid an over‐steering situation.

Ready to level up? The dimension 20 is the perfect lightweight kids bike for riders aged 5½ and upwards who are making the exciting move to gears and going further than ever before! Wide‐ranging and packed with fun, the dimension 20 encourages exploration and rewards curiosity — because the best adventures are always just around the next corner.

Designed with a light aluminium frame, fork and parts, the dimension 20 is that little bit easier to manage — making every ride smoother and more enjoyable. Wide‐range 7‐speed Shimano gearing tackles the ups and downs of both hills and energy levels with ease, while an adjustable fit ensures the bike grows right along with your little rider.

And when it comes to tyres, the dimension 20 means serious business — puncture resistant and reflective 'gravel bike' style tyres are ready to handle roads, paths and tracks whatever the adventure. Rain or shine, day or dusk, your young explorer is covered.

The open road is calling — is your little rider ready to answer?
