Trek Precaliber 12" Kids Mountain Bike 2022
Trek’s Precaliber 12" Kids Mountain Bike is a fantastic introduction to proper bikes, with plenty of features that make it ideal for learning on.
With just one gear and a coaster brake, it is simple to ride but all the components are of good quality, ensuring that the bike is both safe to ride and easy to maintain, so it can be handed down to younger siblings. Weight is kept to a minimum so it is more enjoyable for kids to ride, and with an integrated handle under the saddle and tool-free training wheels, it is perfect for helping them progress. Fat, go-anywhere tyres and low standover height mean that it will provide stability and inspire confidence whether on the driveway, in the park or on the local fields.
Suitable for children aged 3-4, between 91–102 cm / 36–40˝ tall.
Highlights
- Trek Alpha Silver Aluminium frame
