Last year I’ve decided to buy a bicycle to go to my work by it so that I was bored to put up with traffic. It is super comfortable to go elsewhere with the car, I know, but in a traffic jam it can be terrible mostly even if you’re using the public transportation. I thought that if I have a bicycle I can make bicycle commuting. However I had a problem; My apartment is on the 4th floor and on top of that its stairs are prominently narrow. Our lift is also too small to carry a bicycle. So, it would be hard to carry the bike twice a day in this apartment somehow. Then I started to think about folding bike. It is cute, portable, in small size…, but what about performance?
