We integrated Bosch's best drive unit and battery technology with a high quality step-through frame. The result? A great combo for healthy, environmentally friendly mobility. The RT model combines the easy-to-use ethos of all our CUBE Travel Hybrid bikes with the extra safety of an additional back pedal brake - for those who want an alternative to the usual braking options.
The Bosch system is in a class of its own for stability and ride dynamics. We analysed its performance using state-of-the-art measuring equipment and, based on the results, constructed an entirely new, highly stable and exceptionally light step-through frame specially for the Bosch Active Drive Unit. The stability comes from a combination of the oversized, hydroformed down tube, strengthened bottom bracket and head tube areas, double chainstay and double chamber seat tube.
The heart of this bike is the Bosch Active Line drive system with 400Wh battery. If you'd like even more range, the 500Wh is an optional extra that'll allow longer rides. Shimano's 7 speed Nexus hub gear and Magura's HS11 hydraulic rim brake were specially selected for their reliability, and Schwalbe developed their Spicer tyres with puncture-resistant K-Guard technology specifically for e-bikes. Comfort is provided by a suspension seatpost and Suntour NEX suspension fork. Clever details include one key for both frame and battery locks, the central display-activated Busch & Müller LED lights, and a chain guard to keep your clothes clean.
Extremely high tensile strength heat-treated 7005 aluminium alloy is developed for the highest requirements. It is very stiff, fatigue resistant, corrosion resistant and has high elongation. Our Superlite tubes are double butted, giving very light tubesets with a high level of stiffness.
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.
With our specially designed Efficient Comfort Geometry, long distances can be covered easily. Trips with the family, tours with friends or a journey of months - explore the world and life in a new way with our travel series geometry.
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, sleek appearance.
On polished, brushed aluminium and all HPC frames, the logos and graphics are applied in multi-layer wet paint. We use this surface treatment technology mainly to save weight.
The engine is the critical part of an Ebike because of its weight and its junction to the regular drivetrain. These factors present a real challenge for the frame design. This is why 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.
There are two advantages of twin chain stays With an Ebike the new drive loads demand additional frame stiffness that twin chain stays can deliver. At the same time this construction offers the perfect way mount a protective chain case in a stable and way.
With our Advanced Mechanical Forming technology we can mechanically transform different frame tubes and thus optimize them without material-wearing welding work for the respective requirements. Along the obtained organic look, the production method is primarily motivated by functional reasons. Multiple converted tubes enable us to manufacture lighter and also stiffer aluminum frames.
CUBE Bikes with this labelling fulfill all legal requirements and meet all safety demands according to the StVZO German Road Traffic Licensing Regulations. Lighting systems and reflectors mounted are tested and certified accordingly. These bikes take into account every security-related detail to guarantee safe and relaxed mobility in traffic.
