The Orbea engineering team has combined this motor with the 540 Wh battery which we released with the Rise aluminum models. This battery uses 21-700 cells that optimize energy density, meaning more energy with less volume. Its complete integration in the frame reduces the overall system weight and improves stiffness, which translates into better and easier bike handling.
Designing this electric bike and carefully considering all the elements has resulted in unbeatable efficiency which offers high autonomy, with up to 3,500 m of elevation gain and 8 hours of pedaling from a single charge. The combination of the totally new light and compact electric ecosystem, the efficiency of the EP8 RS motor and the new generation of lighter and stiffer frames makes Orbea’s range of electric mountain bikes very efficient: which helps increase the available range by 1.5. Orbea calls this the 1.5x Factor. To put it simply, compared to a traditional e-bike you can expect 50% more the range from Urrun, or a factor of 1.5.
In addition, Urrun brings with it the option of mounting a 252Wh Range Extender, bringing the total capacity to 792 Wh. When multiplied by our 1.5 Factor, the result is no less than 1188 Wh. It’s total autonomy for the most epic adventures.
To charge both batteries, whether it’s the internal battery or the Range Extender, it’s easy to use the smart charger developed by Orbea. This charger extends the life of the battery by up to 30% by adapting the charge to 2 or 4 amps based on different factors, such as temperature, the state of the cells or the number of charge cycles consumed.
A New Generation of Aluminum Frames
Orbea has created a super light frame of the highest quality, offering one of the lightest chassis on the market. Compared to its predecessor, the Wild HT, it is 15% lighter and 30% stiffer.
This weight saving is possible thanks to Orbea’s hydroforming process and triple-butted tubes, which allow very tight control of the tube wall thickness, allowing us to reduce weight in certain places and also reinforce the areas that are subjected to greater stress. As if that wasn’t enough, Orbea has applied polished welding technology for an impeccable finish that improves the performance of the frame.
Another area where Orbea has allocated its resources is in the integration of the Shimano EP8 RS motor in the frame. The “Gravity Casting Interface” integrates the motor in a very clean and compact way inside the frame, keeping it completely protected. For the lower part, Orbea has developed its own protective cover that shields the motor from any impact, weather or unforeseen events.
A New Standard in Integration
One of the most striking features of the new Urrun is the integration of its cables in the handlebar area. Orbea has developed a handlebar and stem that integrates the wiring, routing display and control cables inside the handlebar. The brakes and dropper post cables are routed safely through the stem and headtube.
