The Cube Stereo Hybrid 140 HPC Race 625 is a versatile electric mountain bike which is built to crush trails in comfort. The Stereo Hybrid takes suspension to the next level for an electric mountain bike, with a RockShox 35 Silver fork with 140mm travel and trunnion mount RockShox Deluxe Select rear shock for a highly tuned and optimised suspension unit. The high-performance suspension fork is paired with a carbon/alloy frame, with lightweight carbon front and aluminium rear triangle to maximise strength and handle the e-bike components with the in tube Bosch 625 Powertube Battery. Cube have built-in a semi-integrated seat post, once-screw drive unit cover and internal cable routing for a clean look and reduced wear on the cables.

Sometimes you won’t believe this thing is an e-bike with the way it handles, and the brand new Modular Battery System efficiently integrates the battery into the oversized down tube, which also increases protection for the battery. This system is super simple with its push button release and hidden lock to keep your battery safe. Bosch’s 250 watt CX Generation 4 drive unit works in conjunction with the 12 speed SRAM SX Eagle components for a crisp and natural mountain biking experience.

Everything is built to maximise the fourth generation Bosch drive unit and maximise its power output. Like the larger and tougher bearings, as well as Boost 148 rear which make this one of the best all-mountain e-bikes on the market. You’ll be comfortable, yet ready to attack any track with Cube’s Agile Ride Geometry and Efficient Trail Control Kinematics. When you’re on a bike this powerful you need to be in complete control and the Magura MT Thirty Hydraulic Disc Brakes with 203mm rotors give you the confidence you need to really test the limits of this bike.

The Cube Stereo Hybrid 140 HPC Race 625 sets the standard for all-mountain e-bikes and will not only exceed your expectations, you’ll also impress your mates with your ability to tear up the trails on an e-bike. The Stereo Hybrid does the hard work so you can enjoy the fun parts of mountain biking just like you should.

Features

Agile Ride Geometry: We ran innumerable tests to develop the Agile Ride Geometry in our series of big wheel bikes. Increased fork offsets let us achieve the same trail as our 26in bikes without having to steepen the head angle, thus maintaining generous toe clearance to the front wheel. Secondly we shortened the chain stays without compromising the seat angle. We invented a patented construction to mount the front derailleur to give us more tyre clearance while keeping a conventional seat angle, leading to a perfect riding position for every rider size. Last but not least we kept the BB height the same as on our 26in bikes. 

Boost 148: Boost 148mm technology provides precise handling, on every trail, in every situation. The hub flange moves 3mm towards the outside on both sides. It increases the stiffness of a 29er wheel, by 21%. The reason is the spoke’s wider support in comparison to the 142mm hubs used previously.

Adaptable X12 Hanger: We optimized our new dropout design based on the Syntace X12 through-axle system, enlarging the area of the frame where the hanger is mounted. We can now fit the longer Direct Mount hangers. Shifting precision and stiffness is therefore improved. With the new design it's also possible to swap the whole contact area of the axle with the hanger should the system be worn out.

X12 Through Axle: In this system, a cone is used to form a play-free connection. It is only necessary to tighten the axle from one side. The position of the wheel is done by an insert in the right-hand dropout which is secured by a bolt. The main advantages of the Syntace system are quick and simple changing of the wheel, reliable position of the brake disc and higher stiffness of the rear of the bike. This allows the assembly to be made lighter than a conventional through-axle.

FSP4Link: The key requirement is for continuously active and fully usable travel, with the rear triangle unaffected by pedalling or especially braking forces. There are a number of ways of achieving this – CUBE favours a four bar design with a chainstay pivot. Here, one of the pivots is located between the dropout and the chainstay, ensuring that braking does not have a negative effect on the movement of the rear wheel. By carefully positioning the remaining pivots, we obtain the finest riding qualities for our full suspension bikes both uphill and downhill. 

Integrated Cable Routing: Internally routed cables offer many advantages. Cables are protected from dirt for longer life, weight is saved thanks to the absence of external housing and the bike has a clean, eek appearance.

Frame Safe System: To protect our high-end aluminium frames from damage, they are built with the CUBE Frame Save System replaceable derailleur hanger. The mounting thread is in the hanger and not in the frame as usual. In case of a crash, this hanger can be easily and quickly replaced by a new one.

Integrated Post Mount: The post mount rear brake system is found on all carbon fibre frames and top aluminium full suspension models. Two bolts and the IS adapter aren’t needed anymore, and fewer parts means less weight. In this case we save 30 grams. This may not sound a lot. But there's potential to save weight in every detail.
