Some years back, I was looking at a foldable bike that I think I had posted in this site. It was quite expensive that's why I was hesitating to buy. But from my evaluation, it would be a good bike for those who will use it for their job like a messenger since he can carry it inside the building that he goes to if there is not parking for his bike. And when it rains, he can take the bus with his folded bike. But for a regular rider that is not connected to the job, I guess the regular bike is better because it is cheaper.
