The Cube Acid 200 boys Kids bike is every inch a junior version of its adult counterpart. With a 7-speed transmission and powerful, easily controllable V-brakes, your young rider has everything they need to build their confidence and skills - and have loads of fun in the process. Brake levers are designed to fit small hands properly, and there's a power modulator on the front brake to help prevent accidents from over-enthusiastic braking. With a large 36-tooth bailout gear at the back, it's the bike that'll enable your child to extend their range and have even more adventures on two wheels. The Acid 200's heat-treated, 6061 aluminium frame has the same quality and durability as our full-size mountain bikes. It's light and strong, thanks to a curved and formed down tube that's tailored specifically to a young rider's weight. V-brake bosses front and rear are just the same as you'll find on mum or dad's bike. And, because we know that accidents can happen, we fitted a replaceable derailleur hanger - so that an unexpected tumble doesn't write off the frame.  Cube Acid 200 boys Kids Bike 2021 Features FRAME: Aluminium Lite 6061 SIZE: 20 FORK: Rigid Hi-Ten fork REAR DERAILLEUR: Shimano RD-TY300, 13-34T, 1x7
