I love to work on older bikes and restore many to excellent condition.
I also come up on some real clunkers that the countries of origin should be ashamed! The number one rotten bike, IMO, has to be the Roadmaster. A worse example of engineering would be hard to find! Cheap parts and poor workmanship...this bike line from China seems to have infiltrated the US like a plague. It's almost as if they multiply in the cheapest thrift shops by cloning their beat up bodies, whose rusty gears, thin metal alloy parts, and scratched paint just scream, "JUNK".
I can usually find something I like about almost any bike...except those. Any other contenders for "Worst Bike in History"?
