When you're trying to find your bike's serial number, first check the frame of the bike. This is where you'll find the serial number printed on a sticker. If there are no stickers on your bike, look for them on the bottom bracket.

The start of the serial number almost always references the month and year of the bike’s build. Some brands only include the year but this number or character tends to start the serial number to make it easy to understand.

From there, you will see other characters that could reference the product code, model type, model number, or the batch code of the bike. This changes based on the bike manufacturer but this is why we recommend using a serial number decoder.

Once you have found your serial number, you can head to Bike Index with it. But before you do this, you need to register your bike into the database. From there, you can always look up the number for reference.
