I have an older single speed Dehon and my wife has a newer schwinn 7 speed, both with 20 inch wheels. We take them in the back of our Rav4 with our camping gear when we travel the Southwest each year. We don't do serious distances, but we generally ride for an hour or two each day. They have been dependable and easy to ride. I like working on my bikes, but there has been no repairs needed and the only maintenance has been inspecting everything, pumping up the tires, and oiling the chain.
