CUBE Trail Motion bikes are all about taking our existing mountain bikes and turning the volume up to 11... because it's fun! The Reaction 240 TM starts with Magura's powerful, progressive MT Trail Sport brakes – with an oversize 180mm rotor up front – and grippy Schalbe 2.25in tyres, so your young ripper is always in control. We chose a Suntour Raidon 34 Boost suspension fork too, because it adds an extra shot of comfort and grip, even on rough trails. And, with wide-ranging Shimano Cues 1x9 gears, your youngster has all the range they need to keep up on family rides.
