I was born in the late 60s, so all during the 70s & up to about 1986 I was all into BMX bikes.
I started like all other kids in the mid 70s with Schwinn Sting Rays & Cruisers; then as BMX got big we converted the Schwinns into BMXers; (both 20" & 26"). Then in the late 70s, you just weren't kewl unless you had a real BMX bike!
Anyone who had a old 'tank' bike, threw away the tank & fenders so they would look like the newer cruisers that everyone was riding at the beach! (If only we could have known how much those tanks would be worth some day)!!
