When I was a kid, we had this riding toy with two large equally-sized wheels on the sides and handles you used to propel it. Not sure what it was called but I wish I had one now.

I actually unboxed a TMNT Big Wheel last week and was nearly overcome by the urge to ride it. The weight limit is 70 pounds and I'm nearly 50 pounds over so I restrained myself but it wasn't easy.
