Cube Stereo Hybrid Race 140 HPC 625 (2021)


The new Cube Stereo Hybrid 140 HPC Race 2021 is built around every day trail biking, be it single track, cross country or all mountain. Newly designed for 2021 with Bosch’s latest Gen 4 Performance CX motor, a carbon frame and larger 29″ wheelset, the Stereo 140 models are also a capable bike for aggressive trail riding and fast descending, ensuring a playful ride that’ll handle a wide range of terrain.



Cube Say:

There are times when more really is more. More travel, more versatility, more possibilities. Completely redesigned for 2021, the Cube Stereo Hybrid HPC 140 Race takes everything Cube has learnt about building mountain-taming e-bikes, and re-packages it into a 29er Bosch e-bike that’s even more capable. You’d probably guess from the RockShox Deluxe Select trunnion-mount shock and RockShox 35 Gold fork that they’re serious about its suspension capabilities, and you’d be right. Larger, more durable bearings and a Boost 148 rear end help make this our best-performing all-mountain e-bike to date, helped along by our Agile Trail Geometry and Efficient Trail Control kinematics. But that’s just part of the story.

What’s new:

The all-new, full carbon front triangle is full of neat touches like a semi-integrated seat clamp, integrated cable routing and one-screw drive unit cover. But star of the show is their new Modular Battery System, which houses the Bosch power unit securely completely within the oversized down tube, protected from the elements with a shock-absorbing cover. This new system isn’t just incredibly easy to use – with a push-button release and hidden lock. But also enabled their engineers to create enough space for an optional larger battery, for extended range. And there’s still room for a bottle cage mount, too. Sram’s trend-setting SX Eagle 12-speed drivetrain helps transfer the fourth-generation Bosch CX drive unit’s power to the rear wheel, while powerful Shimano hydraulic disc brakes – with an oversized 203mm rotor up front – work with Schwalbe’s comfy, super-grippy 2.6in Nobby Nic tyres to give you all the control you need.

Cube Stereo Hybrid 140 Race HPC Details:

Mountain bike hybrid versatility has a new name, and that name is Cube Stereo Hybrid 140 Race HPC. Built around Bosch’s new, fourth-generation drive system and drawing on their extensive experience of hybrid power, carbon frame construction and efficient suspension kinematics, it represents a new breed of all-mountain e-MTBs. Cube’s 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.

Their All Mountain Geometry is specifically designed to work with the suspension kinematics and Bosch drive system, offering handling that only Cube’s 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 Cube Stereo Hybrid 140 Race HPC.
