The Precaliber 12 is the perfect first bike for little riders who are ahead of the curve and ready for two wheels at a younger age than most. It has a handle built into the saddle so you can guide them as they ride, and tool-free training wheels that are super easy to install and remove. It's a great fit for kids aged 3-4, between 36 -40" (91 - 102 cm) tall.

This toddler-friendly bike has a handle integrated right into the saddle so you can help guide your child while they ride, plus a coaster brake and tool-less training wheels that can be installed and removed at the turn of a dial. Plus, the lightweight aluminium frame is easy for your little one to manoeuvre.
You want to make sure that your child's first bike is comfortable, durable and fun. Each of our bikes, all the way down to the smallest size, is built to our highest standards, so you can feel confident when you choose Trek for your family.
- 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.
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.
