If you call Fisher they should be able to tell you based on the serial number. Whether they're willing to take the time to research it, I don't know. I do know that a lot of the time the serial number masks other information such as the date of manufacture.

The bicycle looks good, may have minimal cosmetic (only) blemishes on the frame, fork, components, parts and/or accessories. The bicycle may require minimal service adjustments without the need of replacing any parts. Nov 27, 2020 A bike serial number is basically a string of digits that will have between six and 10 numbers in it. It is sometimes referred to as a bike frame number. Your serial number is very important to check on your bike and keep somewhere handy in case your bike goes missing because photos of your bike just aren’t enough in the event that you need.

Notes: This tool works for Schwinn bikes from 1948 to 1982. All serial number records before 1948 were lost in a factory fire.

Serial Number Location

The serial number can typically be found in one of three places on a Schwinn made bicycle.

The headtube
The rear dropout
Underneath the bottom bracket shell

Note: The serial number will always be found on the actual frame of the bike. In other words, it will not be found on a bike component (like a handlebar or a pedal).

Example Numbers

Schwinn serial numbers commonly have one of three formats:

All numbers
One letter followed by numbers
Two letters followed by numbers

Here are some example numbers: 0465228 - F106791 - EB37868

What a serial number can tell you

The serial number on a Schwinn frame will tell you the date that frame was manufactured. It will not identify the model of the bike, only the year the frame itself was manufactured.

MX-II Top Tube(TT)is 18'
MX-III Top Tube(TT)is 18 3/4'
MX-II weighs @ 4 lbs 8 ounces
Series-III weighs @ 4 lbs 1 ounce(Dont forget to weigh clean with no headset or BB cups in.)
