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.
Frame description 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.
Find your size!
Enter your height and inseam below and click on 'Calculate my frame size' to see which size you need. You measure your inseam as follows:
1. Stand barefoot with your heels against the wall. Place your feet about 6 inches apart.
2. Grab a book and place it between your legs, with the short side of the book against the wall. Press the book up against your crotch, mimicking the idea of a bicycle saddle.
3. Measure the length from the top of the book to the floor, the distance you measure is your inseam.
