I bought a cheap Schwinn Loop folding bike for cheap off of Amazon about six months ago. Actually, not a bad bike for the price, and kinda fun to ride on when I'm riding with my young kids. A bit heavier than more expensive folders, but easy to fit in my trunk if I don't want to mess with my rack.
Yes, I own a folding bike... it's made by Montague (montaguebikes.com). Harry Montague invented the first full size folding bike. His son David (an MIT graduate Aerospace Engineer), joined his father in June of 1987 to form a partnership for the design and manufacture of the most innovative folding bicycles in the world. Their sturdy foldable mountain bikes were selected for use by the U.S. Army paratroopers no less! I figured if paratroopers use them, then I shouldn't have any problems with it. And, in the 2 years I've had it, I haven't. It's lightweight and durable and collapses in less than 20 seconds to fit in the back of my (compact) car's trunk with lots of room to spare. It takes up about the same space as a collapsable wheel chair. The company uses only the best available parts that can be found at most bike stores, so no need to worry about your local bikeshop being able to affect repairs or maintenance as you would with some exotic brand name foldable bikes. I use it all the time. I love the affordability, the durability, and features of my Montague X50 folding mountain bike. I think you would do well to check it out if a foldable is in your future.
