The Boss Stealth is the best selling mountain bike in the entire range, and when you check out what spec you get for the price, it's no surprise! Following it's popularity, we developed this smaller 20" version for younger riders - why should adults have all the fun! With a fresh look for the season, the Stealth 20 makes its debut with a bold and brash look, ready to rip up your local trails. The spec speaks for itself – 6 speed Shimano gearing, front and rear disc brakes and dual mudguards give you the kit needed to tackle any terrain, whilst front and rear suspension make for a comfortable ride and soak up the bumps. Deep section wheel rims, off-road MTB tyres and strong disc hubs make the wheels strong and sturdy whilst grippy 1.95″ tyres will pull you through anything. The rear suspension unit can be adjusted to dial-in the required amount of suspension, whilst the front suspension fork remains in action at all times, poised and ready to take whatever is thrown at it. Stand out in the crowd, be understated but be bold. The Stealth has it all! Suitable for inside leg measurement of 51-64 cm /20-25″
