Interesting and unusual bikes

Seemed to be a day for them.  Earlier I had spotted one where the bottom bracket was not co-incident with the join of the seat tube and down tube, but I didn't get a photo.  Spotted this pair from the window of a coffee shop; one is an Elephant Bike, which I must admit to being tempted by but fortunately haven't the money, space or requirement to justify it.  The other I don't know about, it looked like single speed and must have had a rear hub brake.  The owners left before I did otherwise I might have gone and spoken to them (most unlike me).
