Bike info

Not your average 20” kid's bike. The Clash has been developed personally by our CEO and tested by his 6 year old son for over a year - they ride together almost every day! The Clash JR features a lightweight aluminium frame with our own ‘pro kids’ geometry. You will immediately see the stance that a kid takes on this bike - it inspires confidence and puts the rider in an aggressive position, ready to tackle any terrain. The lightweight Suntour fork is fitted with super soft springs - this means that it actually works! Last but not least, the light, large volume Kenda Small Block 8 tires on wide rims can be run at really low pressures, making them super comfortable yet retaining low rolling resistance.


- Light and strong alloy frame
- New School kid's geometry
- Suntour fork w/ soft springs
- Light, high volume tires
- Tektro Novela disc brake
- Shimano 6 spd drivetrain

Perfect for playing in the city, off-road and on pumptracks. Learn how to bunnyhop, rail berms or clear your first small doubles. Our fun machines are built with the same DNA as our dirt and mountain bikes and come in multi-functional, budget friendly packages that riders of all levels will love. Bikes in the Clash range come in three wheel sizes for riders of all ages and are equipped with gears to make sure you can get up hills.
