History of Fuji Bike


The history of Fuji bicycles is one of the most fascinating in the industry. The company has always been considered a leader in innovation and design.

However, Fuji didn’t start as a bicycle-oriented business. In fact, Okazaki Kyūjirō established the corporation as a Japanese-American Trading business in 1899 before it produced quality bikes.

The brand’s original name, Nichibei Shōkai, came from Mount Fuji, a stratovolcano located in central Japan that symbolizes strength and endurance – a trait that Fuji bicycles show.

Since its founding, Fuji has become a beloved manufacturer, although the company experienced some difficulties in the 1990s.

Fuji Bike Serial Number Location


To identify bike by serial number, you must first know where to locate the code.

Unlike Schwinn serial numbers Japan models, which are located on the head tube, you’ll find Fuji bike’s serial numbers located under the bottom bracket of the bike frame, which is near the crank.

It will either be stamped into the frame or etched into it. In either case, you can’t miss it because it’s quite noticeable.

How to Read It?

As mentioned, vintage Fuji bike models have used different serial number patterns since the 1980s.

If the format is anything like the ones mentioned in the table above, identifying the year will be easy peasy.

First, see how many letters and digits the code has. With this information, you can determine whether your bike was made in 1984/1985 or not. If the code looks more similar to patterns for the other years, see if the production year or manufacturing location comes first and proceed from there.
