Just reading this thread and it got me thinking: if so many people don't actually demo bikes (myself included), has anyone bought a real clanger? Or something totally unsuitable?
I suppose my biggest mistake was a Cove Hustler. Bought on the back of a Cove HJ, the angles looked fine on paper, but in the flesh was too short (and on paper the next size up looked like a bit of a gate). A shame, as when it worked it was a great bike, but because of the length it just didn't work enough for me.
