Mountain bike hybrid versatility has a new name, and that name is Stereo Hybrid 140 HPC. Built around Bosch's new, fourth-generation drive system and drawing on our extensive experience of hybrid power, carbon frame construction and efficient suspension kinematics, it represents a new breed of all-mountain e-MTBs. Our engineering team developed a brand-new concept for this frame, building the CUBE Modular Battery System to hide the Bosch power unit completely inside the sleek carbon down tube. A tough cover provides protection and shock absorption for the battery, whilst push-button access and a hidden lock make it both easy to use and secure from unwelcome attention. Even better, the new system frees up enough space for the option of a higher capacity battery than before, which translates to extended range and longer days out in the mountains. The fourth-generation Bosch CX drive unit sits in its own housing, while the aluminium rear triangle features a Boost 148 axle for efficient power transfer, larger bearings for longer life and a linkage designed to fit a trunnion shock. Our All Mountain Geometry is specifically designed to work with the suspension kinematics and Bosch drive system, offering handling that only our fully integrated design is capable of doing – stable, confidence-inspiring and fun. And of course it's chain guide compatible, there's a bottle cage mount for carrying tools or water, and integrated cable routing ensures that gears carry on shifting smoothly with minimal maintenance. Because who wants to spend time fiddling with their bike, when another day in the mountains beckons? All Mountain versatility, redefined: that's the Stereo Hybrid HPC 140.
There's absolutely nothing in the world that our design team likes more than to be let loose on a bike with a brief to simply build the best. And here, in the new Stereo Hybrid HPC SLT, we have one of the results: the ultimate expression of all-mountain performance in a 29er Bosch e-bike, with absolutely no expense spared. With 140mm of travel at the front from the superbly plush RockShox Pike Ultimate fork and 140mm at the rear, courtesy of the equally smooth and progressive RockShox Deluxe Ultimate trunnion-mount shock, there's barely a mountain trail that can't be ridden on this bike. The light, strong and rigid Newman Advanced SL carbon wheelset, shod with grippy and comfortable Schwalbe Hans Dampf 2.6in tyres, transfers the fourth-generation Bosch CX drive unit's power – and your pedalling input – to the ground via Sram's incredible X01 Eagle AXS wireless 12-speed gears. Whatever the climb, however steep the challenge, this is a bike that's up for it. And, coming back down, you've the reassurance of the RockShox Reverb AXS dropper post, RaceFace cockpit components and super-powerful Magura MT Trail Carbon hydraulic disc brakes with oversized 203mm rotors for better cooling. But it isn't just about the components, because the Stereo Hybrid 140 HPC SLT also features our completely redesigned all-mountain e-bike chassis with carbon main frame, revised kinematics and tweaked Agile Trail Geometry for rock-solid handling in any situation. We're particularly proud of the Modular Battery System and its shock-absorbing, dust- and moisture-resistant cover with push-button release and hidden lock. It doesn't just hide the Bosch power unit away inside the sleek down tube, it also enabled our designers to fit a larger capacity battery for extended range – and leave room for a bottle cage mount. It's this kind of attention to detail that makes the CUBE difference, and means you can rely on your Stereo Hybrid 140 HPC SLT in the mountains. However tough the trail, it'll be there for you. Will you accept the challenge?
