Maybe it's my nerdy nature but:- Has anyone identified the bikes? Rod brakes, quite narrow tyres, possibly Westwood rims, black or very dark green paint. Single speed as far as I can tell. There is something that looks like "Nassau Bicycle Company" on one of the chain cases, perhaps the hire company. The head badge surround looks reminiscent of the BSA one though none of the details of the logo are visible. They are repeated on the sides of the forks, and on the seat tube. The 3 chevrons on the top of the forks are possible confirmation. No idea what model.
