Like its carbon sister, Rise Aluminum’s power comes from an EP8 RS motor, developed in an exclusive collaboration between Orbea and Shimano.
Orbea acted on the motor firmware to offer the most natural and efficient assistance as possible, eliminating drag and power delay that’s typical of conventional ebikes. The motor was also optimized to provide maximum assistance between 75 and 95 strokes per minute, the cadence at which the human body pedals the most efficiently and where we normally pedal our standard mechanical bikes.
This means that the harder we pedal, Rise responds instantly with more power, with a feeling of natural assistance.
Another unique aspect of the RS philosophy is its autonomy. Due to the lower power consumption, the lower weight of the bike and the greater dependence on the rider’s legs, the battery in Rise lasts about 50% more compared to a standard ebike. This translates into surprising autonomy for the 360Wh battery in the carbon models and a whopping 540Wh in the aluminum models with a completely redesigned battery.
Weight is another key to Rise and something Orbea invested many hours in to optimize the details of the models: frame, integrated battery, cable routing and push buttons were taken into account. Motor optimization through the Rider Synergy also allows for trail components to be mounted, which saves weight and enables the bike to handle like a mechanical trail bike.
The lightest in the category, also in aluminum
Natural pedaling and handling are the two aspects that differentiate Rise the most. To keep these characteristics intact in the aluminum versions, Orbea’s engineering team scrutinized all the details and invested many hours in development.
The recently debuted aluminum version features a completely redesigned 540Wh battery, developed by Orbea, who rethought the distribution of the 21,700 cells, the housing arrangement, the wiring and the brackets to find a battery that is as optimized and lightweight as possible and with one of the highest energy densities on the market.
For the frame, Orbea selected the best materials and applied the most advanced manufacturing processes, just as it does for its highest-level carbon frames. Thanks to the double- and triple-butted, hydroformed tubes, the team optimized the thickness and shapes of the tubes and reinforced the most delicate areas. In other words, it saves weight where you don’t need material and adjusts the stiffness in the important areas.
