man, that pic brought back early childhood memories. I had one of those as a kid, maybe 1970 or so?
The memory that struck me was of the movable seat with it's peg holes.
I also remeber the "Big Wheel" had hard plastic, hollow wheels...the front tire had almost no traction, and would spin easily.
They also had noise makers on the tire, which my truck driving neighbor made my dad remove ( he slept during the day)
