- Fork: Rigid steel fork for simple, stable handling
- Drivetrain: Single-speed setup with easy pedalling and minimal maintenance

Precaliber 12 is built for little riders who are ready to get going on two wheels earlier than most. The lightweight aluminium frame is easy for children to control and for parents to carry, while the low frame design makes hopping on and off less daunting.
A built-in handle on the saddle lets you guide and steady your child as they learn, without awkward bending or grabbing the frame. Tool-free stabilisers are simple to fit and remove, making it easy to transition as confidence improves.
The single-speed drivetrain keeps things straightforward, and the coaster brake allows children to stop by pedalling backwards, which often feels more natural at this age. Wide 12-inch tyres add grip and stability, helping smooth out bumps on pavements and paths.
Sized to suit children aged around 3–4 years and between 91–102cm tall, the Precaliber 12 is a reassuring, well-thought-out first bike that helps turn early rides into positive experiences.
