....when I was about 14 years old.......I could only ride it in the back yard, but I must have put alot of miles on that bike, because except for when I was in college........I've always had a bike (dirt, road, three wheels, four wheels), didn't make a difference as longs as it didn't have doors...........I was hooked for life. I'm now 67. Been riding for over 50 years.
