The Cube Reaction Hybrid Pro 400 is an E-mountain bike built to tackle new challenges with an agile and playful feel. The Reaction Hybrid Pro 400 seamlessly incorporates the high-quality Bosch e-bike technology with Cube’s quality frame and build process. Cube have put a lot of effort into ensuring that this is not just a hybrid with a motor tacked on, as the bike has been specifically built to give you the most comfortable and natural riding experience you can have on an e-bike. Bosch's motor and battery is integrated so well that many people won't even realise you're riding an e-bike, yet you can still ride further and faster than your friends, with less effort. The Bosch CX drive unit is positioned ideally for comfort and performance, connected to chainstays designed specifically to allow clearance for 2.6 inch tyres.

Bosch e-bike components are German engineering at its finest and they really are setting the standard in e-bike engines and batteries. Bosch and Cube have combined to get every aspect right, the fully integrated battery and motor are protected from the elements, and the battery can be charged without being removed, which is a very handy feature.

The Reaction Hybrid Pro 400 is built to be durable and tough, with features like double butted aluminium superlite tubes and a tapered head tube, for extra strength and reduced weight. Schwalbe's 2.6 inch Smart Sam tyres have the grip to handle a range of surfaces and the SR Suntour XCM suspension fork with 100mm travel will handle all the bumps. While the powerful Shimano hydraulic disc brakes deliver plenty of all-weather stopping power, giving you the ultimate control even in the toughest conditions.

The Cube Reaction Hybrid Pro 400 is a versatile electric mountain bike made for everything ranging from a ride with the family to some intense mountain biking. You can go and test out what a bike with a bit of assistance can do in the wild, you'll be able to go further and faster,  with less effort. You won’t be disappointed with the versatility and reliability of the Cube Reaction Hybrid 400. The Bosch e-bike parts and Shimano components make this bike a trail weapon and an absolute pleasure to ride.


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

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 frames 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 Cable Routing: Cables are protected from dirt for longer life and weight is saved as there is no external housing and the bike has a clean, sleek appearance.

Agile Ride Geometry: We increased fork offsets to achieve the same trail as our 26in bikes without having to steepen the head angle. Secondly we shortened the chain stays without compromising the seat angle and invented a patented construction to mount the front derailleur to increase tyre clearance while keeping a conventional seat angle, for a perfect riding position. We kept the BB height the same as on our 26in bikes. These measures lead to a natural riding position.

Optimal Drive Position: CUBE developed an innovative new frame construction for the new Ebike generation: simultaneously being the cradle for the electric motor, the pivot for the rear link and the seat of the shock eyelet, the very complex area of the bottom bracket is made of two forged halves. The groove in the front section together with the specially formed down tube is home for the power pack which in this way has a very low position in the frame triangle. The positive outcome is an extremely low center of gravity supporting an agile riding characteristic while achieving a super rigid bottom bracket area.

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.
