The Precaliber 20 Freewheel will have your little rider begging to go out for a pedal on their first real big kid bike. It's a great transition model from stabilisers. It has one speed, two hand brakes and a saddle with an integrated handle that can be swapped out for a light mount. For kids aged 6-8, between 129.5 - 149.8 cm (45-52?) tall.
A lightweight Alpha Silver Aluminium frame, one speed and two hand brakes with kid-sized levers that are easy to pull. Plus, a kickstand and a saddle with an integrated handle that can be swapped out for an integrated rear light mount. Everything on this bike is built to last, so it'll still feel like new when handed down to younger siblings.
This bike is the perfect choice for young riders who want to transition from a little kid bike to a big kid bike, with a simple, quality frame that will keep them upright and smiling while they ride at the park with friends or on the local bike paths with your family.
- This bike has hand brakes so kids can gain confidence using them before stepping up to a geared bike
- One speed is all you need ? a simple set-up gives kids confidence and helps them stay in control
- You can replace the saddle's integrated handle with an integrated light mount to boost visibility on family adventures and solo excursions
- Like all Precaliber bikes, the frame is lower so it's easier for kids to stand over and hop on and off
- 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
Trek made their first bikes in 1976 in a barn in Wisconsin. Now they’re one of the biggest bike brands in the world. Trek bikes cover everything from professional-level road and mountain bike race bikes to commuters, hybrids and kids bikes. There is a strong heritage of racing at Trek and many Trek bikes have a strong race influence. They take a very scientific approach to researching bike and human performance and then make the fastest and most efficient bikes they can.
It doesn’t stop their attention and passion for cycling flows through everything they do. Since the 1990s, Trek has supported Places for Bikes. Places for Bikes is an advocacy organisation in the USA that gets more people on bikes more often! Places for Bikes ethos falls in line with the companies mission statement to:
Build only products we love. Provide incredible hospitality to our customers, and change the world by getting more people on bikes.
