Twice the batteries. Twice the freedom.
Riese & Müller was one of the first E-Bike manufacturers to introduce Bosch DualBattery Technology, starting in the 2017/2018 season, and has been equipping many series with it ever since. This makes our E-Bikes and E-Cargo bikes unbeatable when it comes to range and ascent – of course, with a consistently one-of-the-kind riding experience. Besides being able to go twice as far on long trips, you no longer have to worry about your range in your day-to-day riding either.
Two real power performers
Riese & Müller is doubling the battery capacity of its E-Bikes to 1,000 Wh, thus effectively doubling their range. After all, DualBattery technology enables the parallel use of two fully integrated 500 Wh batteries. Heiko Müller, co-founder of Riese & Müller, had this to say about the technology: “In designing our bikes, it is important to us to develop the right concept for each application. For the DualBattery, we dealt intensely with the topics of range and riding dynamics.”
The battery positions
Our engineers have positioned the batteries so skilfully that the additional weight and battery position have no noticeable effect on riding behaviour. Depending on the model, we use two fully integrated Bosch PowerTube batteries, the combination of a PowerTube battery and a fitted frame battery or two frame batteries attached to the frame triangle or to the cargo surface of E-Cargo bikes. You can find more information about the battery integration on the corresponding series pages and in the gallery below.
How does DualBattery technology work?
While riding, the batteries alternate. The system automatically tracks the charge states and switches between the batteries when it detects a charge difference of five percent. This ensures that both of them are discharged evenly, which significantly increases their service life. If necessary, riders also have the option to use just one battery. In this case, it doesn’t matter which unit it is attached to. Both can be charged directly on the bike at the same time or detached and charged separately on an external charger – which is very convenient when no socket is nearby. Both batteries have the same key, which saves time searching for the right one. The same charger can be used to charge the batteries, whether mounted or removed. The charging time for both 500 Wh batteries, starting from a completely discharged state, is about 9 hours, or 4.5 hours for just one of them.
What is the actual benefit?
With the DualBattery technology, day tours of over 70 kilometres are no problem at all, even on our HS models and E-Cargo bikes. This way, you can focus entirely on riding, without constantly being preoccupied by range. For short trips and in day-to-day use, the handy technology requires significantly less frequent charging cycles. And Heiko Müller points out: “Even I did not realise all the benefits of this system until I switched to an E-Cargo bike with DualBattery. While I used to have to charge my bike every two to three days, it is now sufficient to charge it just once a week. This is a real boost in comfort, because I no longer have to worry about my range.” The DualBattery Technology is therefore the perfect solution not only for touring riders but also for everyday commuters.
