The tire was flat, so the motorcycle mechanic went to the roadside to mend it. Is it okay?

Or what? Aren't all the tires mended by mechanics? In fact, many roadside repairmen's tire repair technology far exceeds that of professional motorcycle repair shops. Because the people in the garage are often mainly electromechanical, the unprofitable job of repairing tires is actually beneficial to the old master who repairs bicycles on the roadside.

Tell a joke, my car tire has a nail, so I asked them to mend it when I went to the 4s shop for maintenance (because the nail of the vacuum tire often doesn't leak, my nail can only be repaired after at least 1000 km in the tire). They even said that they couldn't mend tires, that they didn't have anyone who could, and that the repairman who repaired them many times would soon leak air. I told you to keep your money and I'll make it up, because I want to make up the dynamic balance and don't want to go out again! Later, I made it up by myself, using their materials, and then doing dynamic balance.
