Superfly 20 is a great first step for young riders looking to try mountain biking. It has an Alpha Silver Aluminium frame that's lighter and easier to manoeuvre than most kids' bikes, and 20˝ wheels that make it a great fit for kids who are 115-133 cm/45-52˝ tall. Simple, quality components make Superfly 20 an ideal way for your kids to ride off-road with comfort and control.

It's right for you if...
You want your little ones to experience real mountain biking with real mountain bike parts. You want an entry-level MTB that's simple and easy to handle so you can all ride the trails as a family and set the foundation for a lifelong love of adventure. 

The tech you get
This bike isn't just a load of adult parts slapped onto a small frame. All components on this bike feature our Dialed Fit. That means you're getting the right crank length and the right saddle, bars and grips for kids. It also has fast and sturdy Bontrager XR1 tyres, and a simple 6-speed twist shift drivetrain to keep kids rolling.

The final word
Superfly 20 is the ideal entry point for young riders who want a bike they can ride on- or off-road. It's simple enough for beginners, but built with a quality frame and adjustable features that can grow with them.
