Precaliber 12 Bike 2026 – Kids‘

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 ages 3-4, between 36-40? tall.

Features

• 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
• 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
