What is the point of these? (pic)

I found pics online of these (beautiful) bikes. Although I have a few questions about them.

Is there a specific purpose for the leather strap around the top tube?


also

What is the point of the cork hanging from the saddle here on this one. I've seen this around a few times and don't know the reason for doing so. Also seen straps hanging off the saddle as well. Why?


and

can anyone name this drive train?


thanks

It prevents the top tube from being dented when the handlebar swings around and hits it. You could use vinyl electrical tape instead, but the leather looks cooler and matches the bar tape.

I think the cork is to go in the seat tube when the seat is removed to keep out water etc.

Looks like a treadle drivetrain but not Alenax. I'm stumped.

Yes indeedy!!

Treadle drive has been around for as long as the the bicycle has been in existance, if not longer.

I'm not very knowledgeable in these things, but I would hazard a wild guess that the bike is from around the early 1900's. That looks like it could be a pneumatic tire. I think the chain and sproket system to 'Gear up' the drive train was introduced in the mid 1880's on the Kangaroo Bicycle (a highwheeler). Several companies adopted the design and incorporated it into their drive trains. The New Star bicycle had treadles in 1897 that look very similar though simpler and much less intricate to those pictured. Being a model RR buff and an ardent admirer of drive wheel linkages, I can't even begin to describe how beautiful the linkage on those treadle arms appears to me.

So my wild guess would be an early 1900's Treadle driven Safety Bicycle. If nothing else, that should be a good place to start your research. I can't even guess as to who the manufacturer is.

Some good pics and info here, but nothing that closely resembles your photo... http://www.bicyclemuseum.com/alpha.htm
