Trek Precaliber 20 7-speed
Description
- Intuitive twist shift makes it easy for kids to switch gears when their terrain changes
- You can replace the saddle's integrated handle with an integrated light mount to boost visibility on family adventures and solo excursions
- This bike is hand-me-down heaven: it's built to last, so younger siblings can inherit this bike and it'll still feel like new
- Like all Precaliber bikes, the frame is lower so it's easier for kids to stand over and hop on and off
- Investing in a kids' bike from an established bike brand is worth it—Trek kids' bikes are designed and assembled by people who know bikes

Suspension fork
Front suspension absorbs the bumps of the road, path, and trail, and looks cool while doing it.
A better way to produce aluminum
Starting in 2024, we began removing high-emission aluminum from our manufacturing and replacing it with low-emission aluminum made with renewable energy. By October 2025, nearly every alloy bike we make - this one included - had made the switch, driving a major drop in our footprint.
Upgrade your pedals and love your bike more
Pedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride. See the pedal guide and find the best pedals for your riding style. We recommend flat pedals for simple versatility.
