Cube Reaction Hybrid EXC 625 29

About this ebike...

Evolution

CUBE’s dedicated engineering team is never satisfied. For the brand-new Reaction Hybrid 29 – powered by Bosch’s fourth-generation drive system – they went back to the drawing board with a clean sheet of paper and a simple mission: to build the best possible hybrid hardtail frame. Starting with the new Modular Battery System, they designed a new gravity cast down tube to completely enclose the Bosch power unit under an easily accessed cover. It doesn’t just look great, it also frees up enough space for bottle cage bosses and the option of a larger capacity battery for even more range. Oversized chain stays, an X12 Boost rear axle and 1.5in head tube work together to transfer the smooth, powerful Bosch drive unit’s torque to the rear wheel. The widely acclaimed “Agile Ride Geometry” is tweaked and refined to work brilliantly with a 120mm fork, giving handling that builds confidence when you need it and delivers inspiration when you want it. Internal cable routing – including provision for a stealth dropper post upgrade – complements the frame’s svelte looks, and we even designed a trapeze version. Add it all up and it’s clear to see: there’s a Reaction Hybrid 29 with your name on it.

Evolution has brought us to this point: a 29er hybrid mountain bike, powered by Bosch’s fourth-generation drive system and Shimano’s 12-speed XT and SLX components. The Reaction Hybrid EXC 29 is the latest iteration of Cube’s constant quest to build smooth, fast, comfortable and affordable off-roaders. Designed around our brand-new Modular Battery System, it houses the Bosch power unit entirely within the stiff, strong down tube for a sleek appearance and unparalleled usability. Not only is it possible to charge the battery without removing it from the frame, but the new design has enabled the option of an even higher capacity unit for extended range. Revised geometry works with the Suntour XCR34 Boost fork and extra-wide Schwalbe 2.6in tyres to deliver safe, predictable handling that’s lively when you want it, and confidence inspiring when you need it. The uncannily smooth and seamless power delivery of Bosch’s fourth-generation CX drive unit is transferred to the rear wheel via Shimano’s SLX and XT 12-speed drivetrain. Known for its matchless reliability and smooth shifting, the new Shimano 12-speed system also offers an unmatched gear range to make even the most daunting of climbs easier to ride. And, of course, Cube have included powerful Shimano four-piston hydraulic disc brakes at the front, to ensure that you’re always in full control. With a trapeze frame option and a wide range of sizes, there’s a Reaction Hybrid EXC 29 to suit every rider. It’s your gateway to more riding possibilities…
