The Cube Stereo Hybrid 120 Pro 500 has been reinvigorated in 2020, taking an award-winning electric mountain bike to another level. The versatile Stereo Hybrid uses Cube’s new Modular Battery System to integrate the PowerTube 500 into the frame for a clean appearance, the option to upgrade to a larger battery and plenty of room for you to operate in. You can get to the drive unit easily with one-screw access, so that you can be sure your ride is always ready to go. Bosch’s fourth generation 250 watt drive unit will give you the power to cruise up hills and dominate any trail. 

This e-mountain bike is built with Comfort Geometry for a relatively relaxed position that enables you to ride all day and perform at your best. The geometry maximises Cube’s four-bar suspension and 120mm travel RockShox Recon Air fork for a silky smooth and plush ride. The Stereo Hybrid efficiently transfers power thanks to the Boost 148 rear axle and SRAM’s wide-ranging SX Eagle 12 speed drivetrain. Shimano look after the braking with the reliable MT420/400 Hydraulic Disc Brakes which give you awesome control when you need it most. While the wide 2.6” Schwalbe Smart Sam tyres and Cube EXC30 rims give you the lightweight control and durability for the ideal e-bike riding experience. The Cube Stereo Hybrid 120 Pro 500 takes a great bike and makes it even better with the new Bosch e-bike components and comfortable design.

Features

Agile Ride Geometry: We ran innumerable tests to develop the Agile Ride Geometry in our series of big wheel bikes. We also added the 27.5in wheel size to the very well received portfolio. Three important details lead to the very agile character. 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 27.5? wheel by 14% and, for 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.

Wet Paint Surface: On polished, brushed aluminium and all HPC frames, the logos and graphics are applied in multi-layer wet paint to save weight.

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.

Stealth Ready: Dropper seat posts are getting more and more widespread, but to integrate them optimally in the frame, they have to be factory fitted. With the Stealth Ready frames, it is possible to build in a dropper seat post with internally routed cables, which besides the clean look, helps prevent any cables getting jammed. The exit of the cable on the frame – if not required – will be sealed with a cover for protection.

Smooth Welding: This elaborate procedure with doubled weld seams has two advantages: On the one hand, it improves the firmness of the
weld seams and minimizes the load peaks on the tube welds through energy flow and on the other hand, it helps the frame
to a better and more organic look due to the smooth and hardly noticeable welds.

Easy Mount Kickstand: The Easy Mount Kick Stand is a new system developed and designed by CUBE. The base of the stand is mounted from below to a fitting plate integrated to the frame and fixed with a through bolt. This kick stand is extremely stiff and solid through the enlarged contact areas between base and frame which gives a stable stand even with loaded panniers.
