Cube Reaction Hybrid SL 625 (2021)


The Cube Reaction Hybrid SL pushes the limits when it comes to hybrid electric bikes, with a Bosch Nyon display riding an electric bike has never been more exciting and easy! Don’t let the colour fool you…this bike is for the meanest and keenest!



Evolution has brought us to this point: the Reaction Hybrid SL redefines 29er hybrid mountain bikes. Blending the range of Bosch’s biggest capacity battery with the power of its fourth-generation CX drive unit and Nyon controller, this is a bike for explorers and adventurers. Sram’s wide-ranging NX Eagle 1×12 transmission gives you the range you need to tackle any route, while Magura four-piston hydaulic disc calipers front and rear serve up huge reserves of stopping power. The e-bike approved, RockShox Recon air fork has 120mm of bump-swallowing travel. Where will it take you next weekend?

Reaction Hybrid SL Details:

A high-performance e-mtb demands a high-performance frame. With the Reaction Hybrid SL we started with our Modular Battery System, fully enclosing the high-capacity Bosch unit in the down tube. We added a Boost rear end, for efficient power transfer. A 1.5in head tube, for accurate steering. Agile Ride Geometry, for safe, lively and intuitive handling. Internal cable routing for low maintenance and high performance – including provision for a stealth dropper post upgrade. Tested the frame for a 150kg total weight. And finished off, of course, with Bosch’s sublime fourth-generation drive unit, for smooth pedal assistance, mile after mile and trail after trail. There’s even a trapeze frame option…
