The Amsterdam does not have a full chaincase. It's a open back chainguard styled to look like a chaincase.
The Giant Suede Coasting of course has Shimano's auto-shifting 3-speed Coasting geartrain, not a singlespeed coaster brake.
The Schwinn Coffee (and Cream) has f/r caliper brakes, not a coaster brake.

Thanks very much for pointing this out, I appreciate it very much. I made 2 corrections and will check with Schwinn to find out what the actual brake spec is on the Coffee/Cream.
