Why we love it

Trek Precaliber 12 Kids Bike

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.

It's right for you if...
Your kid may be young and small, but they're ready to ride! You want to make their first real bike experience a great one with a bike that's comfortable, durable and fun.
The tech you get
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.
The final word
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.
Why you'll love it
  • 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

What our customers say

Malcolm A.

Verified Buyer

"I've been lucky enough to ski all over the world over the decades. So when I say Racers Edge Wanaka are not only world class but best in class, I'm comparing them globally. Their level of knowledge is second to none and is backed up by customer service I have seldom seen in any industry. They are passionate about skiing and even more so, they are passionate about skiers."

Citrine H.

Verified Buyer

"Wow! My sister and I popped into the store yesterday morning to buy some ski boots. Jessica gave us THE BEST service I have ever received. She was so patient and clearly very knowledgeable. She spent 2 hours making sure we had the best possible boot. I can’t thank her and the team enough."

Andrew S.

Verified Buyer

"Now, I'm a snowboarder and you’re mainly about that two plank ski-life. We don't mix a lot, but I was welcomed with warm arms with my one-plank, and your staff were extremely helpful. I want to applaud your team for one of my best customer service experiences of my life. Thank you."

"Spent a lot of time here this week! Took my daughter in to buy new boots and they refitted her existing boots for $100 instead. Ended up spending my savings on a new set of skis and getting my boots refitted as well. Great advice, smart team, know their stuff."
