Well, the tires are very strong, but if anyone wants, they can change them because they are not of the best quality. Now, as for the iron, I don't know, I've had it for 2 days, I constantly use it and it hasn't run out yet. The secret is that you don't need to pull it all the way to your neck because the rubber will break and the cord will snap, but in case something happens, you can buy new tires and glue the iron. (One star falls due to the poor quality of the rubber.)

Guys, the product is not worth it. I kept it for 20 minutes and took 10 easy rides, then I went to take another one and didn't tighten it much, and this is what you see happened because the point where the rubber goes in is very thin and that's why it broke.
