Cube Reaction Hybrid Pro 500 2021


Giving you that extra boost on long days on the mountain, this electrically assisted Cube Reaction hybrid Pro adds efficiency, adventure and extra time to your MTB adventures. Equipped with a mighty Gen 4 Bosch Performance CX drive unit, getting up and over ridges and hills is made easier but no less fun, while the motor saves your legs for your next off-road endeavours.



Cube’s designers always start with a clear goal in mind. In the case of the Cube Reaction Hybrid Pro, it was a simple one: build a Bosch e-bike that will help its rider get more out of the trails they ride. To that end, they went back to the drawing board for 2021 and came up with a brand-new frame design that’s sleeker, stiffer and more versatile than ever, incorporating Bosch’s fourth-generation CX motor. Integrated cable routing complements the clean lines and reduces maintenance, whilst compatibility with CUBE accessories and a remote dropper post makes upgrading and accessorising a cinch.

The seamlessly integrated Bosch drive unit and battery, controlled via a Purion handlebar-mounted interface, quietly and efficiently gets on with the job of boosting your pedal power for easier climbs, faster routes and expanded horizons. Sram’s superb SX Eagle 12-speed transmission provides an awesome gear range, while Shimano’s smooth, powerful MT200 hydraulic disc brakes ensure you can control your speed whatever the weather or trail conditions. Extra-wide, grippy Schwalbe Smart Sam tyres offer ample grip and cushioning and our Natural Fit Sequence saddle ensures you’ll stay comfortable on even the longest rides.

Cube has years of experience building Bosch-powered mountain bike hybrids – and they put all of that knowledge to good use in the brand-new Reaction Hybrid frame. Designed around the needs of Bosch’s superb fourth-generation drive system, Cube built a frame that’s sleeker, better handling and easier to live with than ever. The Cube Reaction Hybrid Pro 500 houses the Bosch battery securely in its gravity cast down tube, their engineers also routed all cables internally to keep them out of harm’s way and keep gear shifts clean and precise with minimal maintenance. The 1.5in head tube and Agile Ride Geometry delivers impeccably precise steering, there’s an integrated kickstand mount and we even ensured that there’s routing for a stealth dropper post upgrade, so your Reaction Hybrid will stay with you as your riding skills develop. It’s everything that you need, and nothing that you don’t.
