The bike uses inferior solid tires. One drift and one sudden brake can make the tire flat. This not only shortens the service life of the tire, but also makes the tire not round and bumps when riding. A good solid tire will never make such a joke. Looking at our solid tire wear test, we can only see that we are allowed to rub the solid tire back and forth on the ground, and afterwards, as long as we wipe it with a rag, the solid tire is still brand new and there is no trace of friction. Do you still worry about the service life of such a solid tire?
