Where is the frame number on a Riese & Müller bike?
Find your Riese & Müller frame number before you buy, sell or register it.
Find your Riese & Müller frame number before you buy, sell or register it.
Riese & Müller has one of the clearest official frame-number guides. The frame number usually begins with WRJ2 on newer bikes. Older bikes may begin with RM, CUP, AVP, KEP, 6PG or PY. It is usually engraved on the drive side above the motor, sometimes hidden behind the chainring or pulley. Depending on model, it can also be under the down tube, at the bottom of the seat tube, under the battery or on the underside of the drive-side chainstay.
That number matters. It helps you register the bike, check if it has been reported stolen, prove ownership, value it and sell it with more buyer confidence. Here is where to find it, how to read it, and how to check it before you buy.

On older bikes, repainted frames and heavily used bikes, the number can be harder to read. If it has been scratched off, covered, filed down or looks tampered with, treat that as a serious warning sign.
A Riese & Müller frame number usually starts with WRJ2 on newer bikes. Older bikes may use prefixes including RM, CUP, AVP, KEP, 6PG or PY. The number can also be found on the white sticker on the frame, in the e-bike passport and sometimes on the invoice.
Do not use the model name, tyre size, barcode on a shop label, or any number printed on a component. The frame number belongs to the bike frame itself. For example, these are not usually the frame number:
The number you want is the unique frame code that belongs to the frame itself.
The frame number can be partly hidden behind the chainring, pulley or motor area. If you are buying used, ask for a clear photo of the engraved frame number, not just the white sticker or Bosch system number.
A frame number is one of the most useful details on a used bike. It connects a Riese & Müller to its owner, its registration record and any stolen-bike reports.
You may need it to:
If you own a Riese & Müller, take a photo of the frame number and keep it with your receipt. If the bike is ever stolen, that detail can make a real difference.
A clean-looking bike is not always a safe buy. Before you pay, ask the seller for a clear photo of the frame number and check it against stolen-bike records. You should also ask for:

Found the number? Run a free stolen-bike check before you buy. Enter the Riese & Müller frame number into the checker and look for any matching reports. It only takes a moment, and it can help you avoid buying a bike with a bad history. If the bike looks clear, you can also value it and compare similar Riese & Müller bikes for sale.
Report it as soon as possible. You will usually need the frame number, photos, make, model, colour, size, location and any unique marks or upgrades.
Include anything distinctive, such as upgraded wheels, unusual tyres, scratches, stickers, lights, mudguards, racks or replacement parts. The more detail you provide, the easier it is to identify the bike if it appears for sale.
It is usually etched behind the right side of the front sprocket, just above the motor.
It can be behind the left side of the front sprocket, above the motor. The Nevo5 may also use the underside of the drive-side chainstay.
Check above the motor, sometimes behind the chainring or pulley. The Charger5 Mixte may use the underside of the drive-side chainstay.
Check above the motor, around the centre point behind the front sprocket.
Riese & Müller says the Birdy frame number is below the bottom bracket.

The quickest place to find a Riese & Müller frame number is on the drive side, above the motor, sometimes behind the chainring or pulley. Look for the engraved code, usually starting WRJ2, copy it in full, then check it before you buy, sell or register the bike. A used Riese & Müller can be a brilliant buy, but the frame number is the detail that protects you.
