FAQs - Answers to the most commonly asked questions.

How does the E-Bike technology from Riese & Müller work? How do I charge my battery? Why does a Birdy ride like a normal bike?
We answer these and other questions in our FAQs.

  • Can I buy all Riese & Müller models with DualBattery?

    No. Only the Delite, Charger, Charger GX, Packster and Load ranges are available with DualBattery. Special cables and special software are required, which can only be installed when the bike is manufactured. This also means that the system cannot be retrofitted.

  • Can I buy a Riese & Müller bike directly from the factory?

    You cannot buy your dream bike directly from the factory, because Riese & Müller only works with qualified specialist retailers. With over 350 dealers in Germany, you are well served. After all, nobody wants to buy a bike without getting specialist advice first. In our dealerships, you will find professional people who can offer information about your bike, how to look after it and how to care for it.

  • Can I order a Riese & Müller bike in my own preferred colour?

    No, unfortunately this is not possible. 

  • Can I replace individual parts on my E-Bike with others?

    If you have any requests for modifications, please contact your dealer.

  • Can I ride in the rain on my E-Bike?

    Yes. You can use the system in the rain without any concerns. It is protected against rain and splashes, but not against riding through rivers when the motor is submerged in water.

  • Can I ride on my E-Bike during winter?

    Yes. At temperatures down to -10°C, the system works without any problems. Only the range may be a little less in cold weather. At very low temperatures, you should charge and store the battery indoors or in the cellar, place it on the E-Bike immediately before you set off and ride with adjusted assistance. On arrival at your destination, take the battery inside the building with you and charge it again there.

  • Can I ride twice as far with DualBattery?

    Yes, you can ride twice as far. Riese & Müller uses exclusively 500 Wh batteries, resulting in a total capacity of 1000 Wh. 

  • Can I transport my E-Bike on a bicycle carrier attached to my car?

    Yes. There are lots of different carrier systems available on the market. Before making a purchase, check with the dealer whether the carrier system is suitable for your E-Bike.

  • Does the DualBattery affect riding behaviour?

    The batteries are integrated into the frame to ensure their weight has no noticeable impact on riding behaviour. In the Charger and Delite models, both batteries are located centrally in the frame triangle. In the Packster 60 and Packster 80 the second battery even lowers the bike's centre of gravity because it is mounted underneath the cargo rack. With the Load, the second battery is located behind the cargo rack.

  • Do I have to drain the battery completely before I recharge it again?

    No. You do not need to drain the battery completely, because the lithium ion batteries we use do not have a memory effect. The battery can be recharged at any time, so you always have full capacity available to continue your journey. This also means no increased battery wear.
