I had two flats within one month last year, both on my Whizzer, and both the back tire (naturally). One was when the rear hub spoke flange broke and drove spokes into the tube, the second when I caught a slight gap between the concrete road surface and the asphalt shoulder while riding. It caused a split in the seam of the tube at the valve stem. I've since gone to thorn-proofs, as changing pulling the rear wheel to change a tube on the Whizzer is a royal pain.
