Riese and Muller e-bike troubleshooting: manuals, dealer service and warranty

This page covers Riese & Müller e-bikes and cargo bikes, such as the Load, Packster, Transporter, Multicharger, Charger, Delite, Nevo, Culture and UBN models. Riese & Müller's instructions page carries its own owner's manuals plus supplier manuals for the drive systems it fits, including Bosch, Fazua and Shimano, and for parts like Enviolo, Pinion and Rohloff hubs. For drive system checks and error codes, use our Bosch, Fazua or Shimano STEPS page, whichever matches your bike. This page covers what is specific to Riese & Müller.

Before you start

• Riese & Müller says its manuals live in three places: the instructions page, the video guides page, and the manual archive for older bikes (R&M help). The archive covers owner's manuals from 2013 to 2025 and the Birdy and Frog folding bikes.
• Check which motor, display and hub your bike has, then download those supplier manuals from the instructions page.
• Keep your receipt and the service logbook in your owner's manual. Riese & Müller asks for both for guarantee claims (R&M help).

Common problems and what to check

Bike won't turn on, no assist or an error code

• Charge the battery and check it is seated and locked, then follow the power on and error steps in your drive system's supplier manual.
• Use our Bosch, Fazua or Shimano STEPS page for codes, plus e-bike won't turn on, no pedal assist and e-bike error codes.

Battery won't charge or range has dropped

• Riese & Müller's video guides include model range videos, such as one on charging the UBN battery (see Videos below).
• Bikes with two batteries or a battery cover can make charging less obvious. The battery covers video below explains how the covers work.
• Riese & Müller's guarantee expects a battery to keep 60 percent capacity after two years or 500 full charge cycles, whichever comes first (R&M warranty and guarantee). A bigger drop inside that window is worth taking to your dealer.
• See battery won't charge, battery drains fast and e-bike battery care.

Worn parts, noises and drivetrain

• Riese & Müller says some parts wear with use, depending on care, mileage, rain, dirt and salt. Its owner's manual lists them in the chapter on inspections and service life, and worn parts are not covered by the statutory warranty (R&M maintenance, wear and repair).
• Your dealer can look up the correct part in Riese & Müller's parts list, order it and fit it.
• The general video guide playlist on the video guides page covers jobs such as removing the rear wheel, cleaning the drive and adjusting the suspension.
• See e-bike noises, e-bike brakes and flat tire.

App, GPS and alarm

Bikes with an RX Chip can use the Riese & Müller RX Connect app for GPS location, a lock alarm that warns of movement, ride statistics and the RX Chip's own battery status. If the app stops showing your bike after a long idle period, the RX Chip's battery may need charging (R&M RX Services).

Service intervals

Riese & Müller says the first service is due after 400 km at the latest, then every 2,000 km or once a year from the date of sale, whichever comes first (R&M maintenance, wear and repair). Your dealer records each inspection in the logbook, which matters for the guarantee.

Warranty and dealer service

• Your Riese & Müller dealer handles service, maintenance, repairs and warranty work. That is the dealer you bought from, or the Service Hub you chose when buying online. You can use another dealer, found through the dealer search (R&M maintenance, wear and repair).
• For damage or a guarantee claim, contact the company that sold you the bike with your receipt and completed service manual. The dealer then contacts Riese & Müller for you (R&M help).
• The voluntary guarantee covers the frame and rear swing arm against breakage for five years and the battery for two years. It needs you to be the first owner, register the bike online within four weeks and keep the logbook complete. Drive parts from makers such as Bosch, Enviolo, Rohloff and Suntour are handled by your dealer with that maker (R&M warranty and guarantee).
• Riese & Müller Customer Care can help with product questions a dealer couldn't answer, small non safety parts, and cases where communication with a dealer has broken down (R&M Customer Care).
