The tires are 20x3", I guess i could ride with lower tire pressure to allow more comfort.
The folding mechanism is rather elegant, doesn't add much weight to the bike, but allow convenience when you need to fit the bike into a car.
I can easily fit the Dolphin into the back of my Prius, if it was much heavier, it would have been more difficult.
