Many bikes will have both a serial number and a QR code. The number is usually printed or engraved. The serial number can be found on most bicycles. But don’t worry if you can’t find a serial number, because there are many ways to tell what model a bike is. There are even websites dedicated to vintage bikes, like Vintage Trek.
You can also look up the serial number online at sites like Bike History. This can be helpful in case your bike is stolen. Some brands also encode the manufacture date on the serial number. Bicycles with authentic serial numbers are very valuable, as they allow manufacturers to trace the history of the bike. Serial numbers are a great way to find out if a bike is authentic.
Although you may be able to find a model online, it may be difficult to know if it is original or not. Knowing the make and model of a bike is vital when you want to find the right bike for your needs.
