Schwinn Qualifier- mini bike
This isn't a folder but since it uses 20" wheels, it fits in spaces that a full size bike can't.
The frame is a late 80's Schwinn Qualifier BMX racer. From what I've gathered, these bikes were used in a short lived road(parking lot) racing series in the late 80's. I liked it because it will take either 451 or 406 size wheels and will accomodate road brake calipers.
I found the frame on eBay. I ground off the unused derailleur cable guides and sprayed the frame black.
I'm running 451 Sun CR18 rims laced to Shimano DX BMX hubs. I had use a longer axle on the rear hub since this bike has 126mm rear spacing.
The brakes, levers, headset and cranks are Dura Ace. 45T front and 13T rear gives me 70 gear inches.
Last Saturday I took it on a 70 mile ride. The bike is stiffer than my Bike Fridays but it is not uncomfortable. The handling is very similar to other 20" bikes.
