My first real bike has been a folder, and having ridden it 3000 miles, I have no desire to buy a full size bike. The other week I was out of town and rented a full size commuting bike. I hated it. I found it too difficult to maneuver . What I disliked most was the center bar that prevented me quickly hopping on and off it. I also found it slower to accelerate because of the bigger wheels, which is a big disadvantage for city riding. Speed wise, it seemed the same as my 20" folder, if not slower.
What are other people's experiences?
