INSTORE COLLECTION AVAILABLE
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 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.
You shouldn't buy your kid's bike where you buy your cereal – Unlike big box brands, Trek kids' bikes are 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.
