Mongoose Rockadile 20″ Boys MTB Grey


The Mongoose Rockadile is a youth mountain bike which is at home on the bike paths or easier trails. Designed for 8-11 years olds the Rockadile is built around the tough and light T1 aluminium frame with internal cable routing to minimise maintenance. The Xposure fork with 60mm travel gives this bike some capability to head off-road and is more than enough for most kids on the dirt. The 3×7 speed Shimano drivetrain will help give kids experience on a geared bike with a range of gears to help them climb and descend. The Rockadile rolls on tough aluminium double wall rims and 24″ Mongoose tyres with a good combination of grip and speed. Kids can ride in control with alloy rim brakes for simple and easy braking power. The finishing touch is the alloy hubs and QR front axles for convenience. The Mongoose Rockadile is a great first mountain bike for any kids, it has everything kids need to develop their skill and have fun, without any unnecessary extras.

All bikes purchased in-store come fully assembled with 12 months free servicing!
