The Ridgeback Dimension 24 is a lightweight, premium children’s bike built for confident riders aged around 9 to 12 who are ready to ride further and explore new terrain. With a durable aluminium frame and quality components throughout, it delivers a smooth, comfortable ride whether cruising local cycle paths or venturing onto light trails.
Constructed from butted 6061 heat-treated aluminium, both the frame and fork keep weight low while providing the strength needed for everyday adventures. The addition of an 8-speed Shimano drivetrain gives riders a wider gear range to tackle hills, longer rides and mixed terrain with ease.
Fast-rolling 24-inch alloy wheels paired with grippy tyres provide stability and control across a variety of surfaces, from paved paths to gravel tracks. Reach-adjustable brake levers and dependable alloy V-brakes ensure confident braking designed specifically for younger riders.
With child-specific geometry, adjustable components and a robust build, the Ridgeback Dimension 24 grows with young riders and supports their progression into longer rides and more adventurous cycling.

Information for Ridgeback kids bike range:
Easy-pedal cranks [All models except Scoot and ScootXL]– Ridgeback's 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 – Ridgeback's 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.
Lowered frames – Ridgeback's frames are lower where it counts, making it easier to get on and off and increasing clearance for greater confidence.
Steering limiter [All models except Scoot and Dimension 27.5] – 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.
Better brakes – Brake levers are closer to the bars and adjustable for reach to suit smaller hands, and work perfectly with our smaller diameter grips.
