Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

Trek Precaliber 12 Hybrid Kids Bike 2026 in Flamingo Pink

Season:2026

Brand:Trek

Code:5271578

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
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
