The Cube Reaction Hybrid EXC 625 is an electric mountain bike that rides like your normal hardtail with the added power of Bosch electric bike components. Bosch’s fourth generation 250 watt Performance CX drive unit and PowerTube 625 Battery are integrated in the tube for good looks and a smooth ride thanks to the brand new Modular Battery System. The aluminium frame in which the Bosch components are integrated into is lightweight and durable, designed with Agile Ride Geometry for a nimble and comfortable ride. This geometry is built to make the most of the Suntour XCM34 fork with 120mm travel and wide 29er Schwalbe tyres for a smooth ride with excellent handling and control. Cube built the Reaction Hybrid EXC 625 with an X12 Boost rear axle, oversized chainstays and a 1.5” head tube which all work together to transfer the torque from the Bosch drive unit the the rear wheel for optimal e-bike performance.
The Bosch drive system works with Shimano 12-speed XT/SLX Components so that you can attack any climb with comfort and efficiency with the excellent range of gears. Shimano provide equally brilliant braking on the Reaction Hybrid with MT420/400 Hydraulic Disc Brakes for excellent control and the confidence you need to attack the harshest trails. Cube even built in the ability to upgrade to a Stealth Dropper Post so that you can really customise this ride to suit your style.
The Cube Reaction Hybrid EXC 625 is the electric mountain bike built for an agile yet smooth ride on any trails. This bike ride like your regular mountain bike, but without the challenge of grinding up those crushing hills, the Bosch drive unit will take care of the tough stuff while you enjoy the fun.
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.
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.
