I like these Rawland bikes, a real jack-of-all-trades. This pre-owned example is in excellent, low-mileage condition. Whether you need a commuter, tourer, weekend cruiser, mountain bike, or any other kind of real-world bike, this would be a good choice.
I think this is a size M. Measurements are:
seat tube c-t: 20"/50 cm
effective top-tube c-c: 22"/56 cm
standover at mid-point of top-tube: 31"/79 cm
The head tube is tall and the steerer tube is long, so getting the bars up high isn't a problem. With a few fit adjustments, this should fit most riders between 5'4" and 5'10".
The parts are mostly Deore/LX level with Tektro brakes and levers and a Sugino XD crank. Wheels were handbuilt by me on the elusive but excellent Rigida Sphinx 650B rim (36h front and back).

We also have this lightly used 54 cm Rambouillet:
My wife rode it a bit (maybe a few hundred miles) before we had our 2nd and 3rd kids. Now she rides a Long Haul Trucker, which is better suited for pulling trailers and carrying kid seats.
