The Dimension 27.5 — Big Bike Performance, Unbeatable Value
The lightweight Dimension 27.5 is designed to be the ultimate mix of ability and value for young adult riders — and it delivers on every front! Suitable for riders aged 11 and upwards up to 162cm tall, the lightweight Dimension 27.5 bridges the gap between kids bike and full adult bike with style, confidence and a whole lot of fun.

Packed with many of the easy-ride features and fit details from our smaller bikes, the Dimension 27.5 takes things up a notch with full-size 27.5″ wheels and a wide-ratio Shimano Essa 8-speed gear system — because this really is a small adult's bike rather than a children's bike. Tackle every hill, track and back lane with ease, knowing the right gear is always just a click away.

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 Speedsters with puncture resistance and reflective sidewalls roll comfortably and smoothly.

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

Supporting Accessory Range — For gifts, customisation or just getting co-ordinated!

Transferable warranty — Our lifetime frame and fork warranty and 2-year parts warranty is transferrable, supporting service and re-sale value. Because these bikes are made to last.

What are the parts differences between the Dimension 27.5 and the MX27.5?
