Maximum trail performance and maximum fun! When we set out to design the first generation of our Stereo Hybrid, these two attributes were top of our list. The aim was to translate our acclaimed expertise in developing high-performance chassis for traditional mountain bikes onto our e-mtbs. We collected masses of data using state-of-the-art measuring technologies to understand the demands of the Bosch drive system. Then we built the perfect frame using Efficient Trail Control and the Optimal Drive Position to maximum effect. Countless test wins show that our efforts have paid off.

Although the focus of the first-generation Stereo Hybrid was very much on performance, battery integration was already a high priority. Our Semi-Integrated Battery concept, the first of its kind on the market at the time, not only allowed us to incorporate technical advantages such as a lower centre of gravity and protection against battery damage, but also set groundbreaking trends in terms of design.

When we rolled out the second generation of Stereo Hybrids in 2016, the spotlight was on optimisation. The addition of the Stereo Hybrid 160 platform to our product range brought with it extensive improvements to our acclaimed frame. Our Tuned Drive Position technology rotated the Bosch mid-ship drive unit even further and the new position – together with our CUBE Design Cover – allowed us to dramatically reduce the length of the chain stays. Combined with the launch of the Boost 148 standard and increased overall stiffness, we achieved the best handling on a mid-ship-drive bike yet seen on the market and excited the media world once again.

Technologies like smooth welding and internal cable routing throughout, coupled with intelligent tweaks and improvements like the addition of in-frame charging, made the Stereo Hybrid platform a showpiece for the e-mtb world.

The application of our extensive experience in carbon frame construction was the crowning moment for the Stereo Hybrid range. Now, thanks to the Bosch PowerTube battery concept, we have raised the bar even further with our Stereo Hybrid platform for the 2018 model year. We successfully took our expertise in gravity casting technology from the Reaction Hybrid and applied it to the construction of full-suspension e-bikes. With our Fully Integrated Battery technology, we are once again setting new industry standards for design and freeing up additional technical and functional advantages such as the option to mount bottle cages. With yet further improvements to the geometry, the Stereo Hybrid platform for 2018 hits never-before-seen heights. Welcome to the future!

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.

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. All Mountain versatility, redefined: that's the Stereo Hybrid HPC 140.

The Stereo Hybrid 140 29 Special Edition showcases just how far e-mountain bikes have come in the last ten years. It's still a very young segment, but one that's evolved at a breathtaking pace so far. The developments are unreal. The drive unit boasts sensitivity, efficiency and performance like never before. To complement this, we added a completely wireless electric drivetrain and dropper seatpost. Everything from the chassis and wheels to the brakes and tyres have been carefully selected to work in perfect harmony. The bright, robust display is no longer just a speedo; it's an all-in-one navigation guide and fitness trainer with stats and much more besides. And the whole thing is wrapped up in our High Performance Composite frame utilising state-of-the-art carbon technology, geometry and kinematics to create the ultimate high-tech machine. The unique design and careful attention to detail are sure to make this special limited edition bike a true highlight of the upcoming season.
