I've decided I must have a folding bike. I recently moved halfway across the country into a tiny apartment and the big bikes had to be left behind. We literally have no where to store a full-sized bike.
The problem is that I know absolutely nothing about folding bikes and they seem really expensive. I don't have a whole heap of money. I've been looking at the Citizen bikes and my husband seems to think something under $300 is reasonable. I'm mostly curious about wheel size. What is the difference in ridability on a 16" wheel v. 20"? Also, what does a first-time folding bike owner/rider need to know about them?
