I located the serial number on the bike. It starts with w90. I then assume that the 90 stands for the year of manufacture. I was in college at University of Florida then and was biking the trails around Gainesville. Lots of fun memories from those days! My son went to UF in 2016 and I made him take my bike. He rarely used it. It somehow avoided being looted of damaged. However one day a homeless man told him “he needs a better bike” and that was the hilarious to both of us. The bike is special to me but not him. I’m tuning it up now and giving it new life!
