The Trek Precaliber 12 is the ultimate starter bicycle engineered to help young adventurers transition smoothly into the world of two-wheeled fun. Built around a durable yet lightweight Alpha Silver Aluminium frame, this bike ensures effortless handling, control, and maneuvering for little arms and legs. The lower standover height makes hopping on and off completely stress-free, while the tool-free adjustable training wheels allow you to install or remove them in seconds as their balance improves. Thoughtfully tailored with child-specific ergonomics—including a padded saddle with an integrated guide handle for hands-on assistance, narrower handlebars, and an intuitive coaster brake—every detail is crafted to instil confidence, safety, and endless joy on footpaths and park loops.

Ideal First Pedal Bike: Designed specifically for children aged 3 to 4 years old (height range between 86 cm and 102 cm) who are ready to start pedalling.
Parent Friendly: The integrated saddle handle takes the strain out of helping your child find their balance.
Hassle-Free Assembly: Training wheels click in and out without needing to drag out the toolbox.
Built Tough: Engineered by Trek to withstand heavy toddler use and easily be passed down to younger siblings.
Rider Has Outgrown 12" Wheels: If your child is taller than 102 cm or older than 4, a 16" wheel size (like the Precaliber 16) will provide a better long-term fit.
Looking for Hand Brakes Only: This model primarily uses a back-pedal coaster brake to keep stopping simple for beginners, rather than dual hand lever assemblies.
For safety reasons, bikes cannot be shipped directly to consumers unassisted without full professional assembly or inspection by an authorised retailer.
