A fat tire Schwinn with a no fenders, 24" wheels and a coaster brake and rear hub which only worked "most of the time". I inherited it from my brother and couldn't quite reach the pedals when I sat on the seat for the first year. I rode bare-footed most of my first couple of years in the warm weather and learned to weight the outside pedal in a turn by losing the toe-nails on my inside foot a couple of times. A lesson I remember to this day. Just less than a half-century ago.
