Highlights
The Cubley 18 features a lightweight, size specific alloy frame and is driven by a size specific crank set to suit their little legs. It rolls on 20h wheels, has 18" Deli tyres and a cool junior specific saddle. The reach is also reduced with the use of a super light one-piece handlebar and stem.
WEIGHT MATTERS
The Cubley 18 only weighs 7.56kg making this one of lightest bikes in the world for it’s price point and specification! Less weight helps smaller riders start easier, accelerate faster and handle the bike with more control.
Reviews

“These are excellent bikes. My daughter got hers a week ago. Within the first hour she was riding, with a bit of a wobble. Two days later she was riding easily on her own. Really pleased with our purchase”
