Product Description
- This bike is a memory-maker: seeing your child ride their bike for the first time is something you'll never forget
- 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
- 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
- Like all Precaliber bikes, the frame is lower so it's easier for kids to stand over and hop on and off
Integrated handle
Hidden handle under the saddle helps you guide your child while they learn to ride.
Toolless training wheels
When your little one is ready to ditch the training wheels, the only tools you'll need are your hands.
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.
