• INSEAM: 49 - 57 cm

Less can be more. The Acid 200 SLX takes the same successful formula as the Acid 200, trims what little fat there was to make an even lighter and livelier bike, and adds to the spec too. We chose a Microshift 9-speed 11-42T cassette for an extended gear range, so your junior mountain biker will have the confidence to tackle even more challenging climbs. A thinner handlebar and grips make it easier for small hands to hold on, steer and brake. And grippy tyres, powerful brakes and safe handling round out a package that your young rider will love.

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.
