There are times when more really is more. When we first launched the Stereo Hybrid HPC 140 Race, it quickly established a new benchmark for all-mountain Bosch e-bike performance. More travel, more versatility, more possibilities. Completely redesigned for 2020, the new version takes everything we've learnt about building mountain-taming e-bikes, and re-packages it into a bike that's even more capable. You'd probably guess from the RockShox Deluxe Select trunnion-mount shock and RockShox 35 Gold fork that we're serious about its suspension capabilities, and you'd be right. Read more... 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. 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 our 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 our 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. And, because a bike like this is going to inspire you to do more, we even fitted a remote dropper post - so you can explore new lines. It all adds up to a compelling reason to get out into the mountains and ride. Will you rise to the challenge?
