I bet you had a Big Wheel. I had this pink and white bike and I would ride it all day long. It was probably my all-time favorite toy as a kid.
I did have a Big Wheel, I was Hell on a Big Wheel with that thing, loved going down the hill in our backyard on that thing then hitting the brake (that little handle on the right hand side, and sliding through the grass.
I am sure you were an adorable kid, so I am sure you looked adorable riding it.
