Re: Need to decipher year of Huffy BMX bike serial numbers I just picked up a Huffy Pro Lightning Serial H 66533 I realize this is an old thread but instead of starting a new one, i thought id drop a line here. Midifile optimizer 8 serial.
To date Huffy bicycles, first, you must find the serial number. The first digit in the number is the last digit in the year it was built. Second, you must look for other features or characteristics that would determine it's decade. Your bike's number starts with '7'. This would mean that the year is 19-7. Now, the characteristics and features. You're bike has a sprocket, color scheme, and reflectors that would most likely put it in the 60s or 70s.
