The Reaction Hybrid Rookie takes all the race-inspired handling and performance of our adult Reaction bikes, and repackages it for keen junior riders. Powered by Bosch's third-generation Performance drive unit, there's plenty of juice to help your youngster keep up on longer family rides. Smooth-shifting, wide-ranging Shimano Deore 10-speed gears are easy to use, and they're backed by powerful Magura MT Thirty hydraulic disc brakes for safe stopping. There's a Suntour air suspension fork to help smooth the trail, and 2.25in tyres for grip and comfort. Just add a spirit of adventure, and go!
Frame description We use the same technologies and frame construction techniques with the Reaction Hybrid Rookie as we do with the adult bikes that inspired it. For example, the gravity cast down tube and 1.5in head tube create a stiff backbone for a bike that, let's be honest, is going to be ridden with healthy enthusiasm. Internally routed cables keep gears shifting smoothly with minimal maintenance, and there's even provision for a simple upgrade to a dropper post for added confidence out on the trail. Feed their sense of adventure – and see the positive reaction.
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.
