Before they can hit the trail or pull any tricks, kids have to learn how to ride, but it can be tough! Traditionally kids bikes are just scaled down versions of adults bikes. This doesn't take proper fit or pedalling mechanics into consideration.

To tackle this problem Mongoose has developed a new line of KidFit bikes which are specifically designed for the next generation slayers. Narrower cranks, a more kid friendly geometry, optimised gearing and smaller touch points are all designed to build confidence for kids. Plus the bikes are designed ti fit growing kids for a longer time, all of this combines to create a ride fit for just a kid!

Mongoose KidFit technology has been embedded to the design of every Mongoose juvenile bicycle including the 2021 Lil Goose Boys 12" BMX. Learning to ride can be tough, but KidFit features like easier gearing and improved rider positioning help to make those first experiences a easier.


  • Mongoose aluminium frame with KidFit geometry.
  • 24/16 tooth drivetrain with 1 piece forged steel 89mm crank.
  • 12" wheels with 2.125" sidewalk tyres.
