I often see a hole on a public bicycle. Then I check it. What does it feel like to have a durable tire?
Upstairs is very objective, is not now tire, but I tried several free pneumatic tire, I personally feel the resistance is still relatively good, they now than before the kind of soft material a lot, but still less than the pneumatic tyre, hope to be able to continue to improve.
Greater friction, more difficult, speed up a little better feeling, but also used in the road is very bad place, or used as public facilities.
This kind of tyre is much heavier than regular tires, because it is free from inflation and easy to maintain, but it starts relatively slowly when it is stepped on
