I've got 700 miles on my Baldwin Cafe Seat. Here's my 2p:
Comfort: CRAZY comfy. Just nuts. I don't do mega rides but 2-3 hours no problem at all. None. Stocker was pain in rear at 30 minutes. No break in for me whatsoever with Baldwin seat. I'll get off the bike after a couple of hours and realize I did not stand up once and did not think about my rear end once. Can't comment on longer rides then that as I have not taken any. I'm about average when it comes to comfort expectations.
Aesthetics: Personal of course but I get positive comments on it all the time. Bike is new so seat doesn't stand out to any great degree but I still get the comments. I'd say nearly everyone that has taken a close look at the bike has commented positively on the seat. More importantly, I love the way it looks.
Customer Service: Well, they did deliver when they promised. They did refund my seat exchange deposit in a timely fashion. Communication was solid. (One clitche - see below)
Minor quibble - if that: The seat was higher than stock and was not supposed to be. I am certain it was higher because on the first ride I looked in my mirrors and saw my elbows. I also caught a blast of air over my Givi screen. Fortunately I was able to raise the screen and it was fine.
I spoke with Loren at Baldwin about this (mostly out of curiosity as I was ok with it). He said different seats have different riding positions but the seat he built was the same height as stock. OK ...???
I'm passing this along as an FYI because the seat is custom and pricey so if height is critical you may want to talk with Loren about height before you buy.
Anyway, great seat. Comfy beyond belief and very attractive. Here are some pics on the V.
