Rare Schwinn Collegiate 3 - $120 (UK Campus)

Schwinn internal 3 speed road bike 18" frame its a rare find

Since I was talking about rarity here are two examples of salesmanship.  Presented without irony is a "Rare Schwinn Collegiate" which is probably one of if not the single most common bike on the used market.

RARE Vintage 1970's Sekine 10 Speed (Ten Speed) Road Bike - $125 (Downtown Lex)

I have never seen another Sekine in my life, and I am an avid bike spotter.
This bike was constructed on a joint venture between Canadian and Japanese bike manufactures.

It features:
-A versatile medium sized frame (54-56cm). Good for both guys and girls of average height
-A sturdy lugged steel frame
-Original Shimano Components, including drop-tube shifters
-Alloy handlebar stem
-Engraved drop bars
-27" Continental Ultra Tires
-Aluminum Quick-Release front wheel
-The most unique engraved pie plate I've ever seen
-A brand new Planet Bike comfort seat

It's true, I haven't ever seen one of these either.  All the signs point to low end and maybe department store bikes.  Sekines were  a Japanese company that wound up producing bikes in Canada to avoid import tariffs to the US.  This would have been one of their lowest models.  Again, uncommon but not rare.  You can bet any company that's going to open a factory in North America specifically for the import market did not intend to be anything short of ubiquitous. 

You have to admire their bravado, they sold themselves as the finest bicycles ever made.  And turning that dorky pie plate into a selling point is something else, it wouldn't stop me from pulling it off but hey, nice shot.  Everything about this bike is cheap but part of the fun of the secondary market is picking up oddball stuff and messing around with it, which you could certainly do here.
