The Trek Precaliber 20 7-Speed is a fantastic step up for young riders who are ready to start exploring beyond the pavement. Sized perfectly for kids aged 6–8 years (or 114–132cm tall), it strikes the right balance between fun, confidence and control.
At the heart of the bike is a lightweight Alpha Silver aluminium frame, strong enough to handle a child’s everyday adventures, yet light enough to keep things manageable when it's time to push up hills or load into the car. The frame is designed with a low standover height, making it easier to hop on and off.
Helping absorb trail chatter and uneven surfaces, the 35mm travel front suspension fork boosts comfort and control, especially on paths and light trails. Shifting gears is made simple thanks to the Shimano 7-speed drivetrain and twist-grip shifter, which kids can easily master to suit different terrain.
Alloy linear-pull brakes provide reliable stopping power and are paired with short-reach levers for smaller hands. The bike rolls on 20” alloy wheels fitted with wide Bontrager XR1 2.25” tyres, delivering good grip and cushioning on varied terrain from pavement to packed dirt.
The integrated saddle handle is a practical touch for parents—it makes lifting, parking or steadying the bike easier, and can be swapped for a rear light mount for added safety. Thoughtful extras like rack and kickstand mounts mean you can customise it as your child grows.
Built to last and designed by the experts at Trek, the Precaliber 20 7-Speed is a reliable, fun and confidence-inspiring kids’ bike that’s perfect for years of family rides, outdoor fun and skill building. Whether it’s school runs or weekend trail loops, it’s ready for the next adventure.
