General commercial bicycles have a body number. It is an industrial serial number that is on the frame. Otherwise, wheels and cranks also have serial numbers. The number is vital in product management, but it is not so essential in crime prevention. For any accident, the police officer will only look at the crime prevention registration.
Bike Serial Number
Meaning of bicycle serial number: As mentioned above, the body number of the bicycle is the serial number. It is a number for product management that has no unique format as the manufacturer and factory decide arbitrarily. There is a stamp on the frame for domestic bicycles, city cycles, and common bicycles. There is a number engraved on the top tube in front of the frame, and it is the bike serial number.

Some bike parts have no serial number: The bike is not a collection of individual parts. There are some parts usually sold separately. Overseas bikes may or may not have a serial number.
There is a reason for number scraping: However, number scraping is a product with a translation. The numbering of used frames is in the gray zone. There is a high possibility of stealing goods.
In the past, a major famous bicycle second-hand dealer handled number-cut products with no check: People criticize it both inside and outside the country. In this way, gray bodies are distributed in the recycling and reuse worlds. Bikes with the beginning and end partially removed are often available in reused vehicles.
Some bike parts are often removed: It happens during the distribution stage. They rumor overseas stores will sell sideways, unsold, and samples.
The serial parts are not useful for crime prevention: Ultimately, the parts are not bicycles. Only the frame of the main body is a bicycle. If the police try to determine the serial number of individual parts, it will take time and effort to lose the cost. And we cannot check the small numbers of dozens of parts one by one.
Serial number position: The position of the bike serial number is different. It depends on the manufacturer, production year, and model.

Many body numbers may include the date the bike was manufactured. It is a number that shows when the manufacturer manufactured and completed it at the factory. It is not only the time when the bicycle was manufactured but also the location of the factory.
