Great collection! I've had my Racycle since 1987, It had the one piece bent wood handlebars you mentioned and I hope to get them back someday, they got left with an old roommate when I moved! He says he still has them and just has to dig them out of his storage. One thing that seems pretty different is mine has a rear suspension similar to much newer bikes although it's very old and looks original to the frame, is anyone familiar with this? Also, my front wheel was replaced with a steel rim, any idea where I might find a wood rim. I'm sure the saddle on mine isn't original either but, it's still a very cool bike!
Mine is a fixed gear and I did ride it on the street when I lived in Boston, ONCE...that was enough, it was fast and scared the hell out of me!
I just did a image search and found images of a racycle with the rear suspension but mine also has the springer fork the same as the one you have pictured on yours with the wood bars... Also, it seems to read that the racycle pictured with the rear suspension was made in Berlin On.? Mine was made by the Miami Cycle co. Unfortunately, I don't have immediate access to mine, but I will take pics of it the next chance I get.
