If you’ve ever been riding your bike and gotten a flat while you’re far from home, you know how much of a pain it can be to deal with. At least with your car, you generally have a spare, and the tools to change it. On a bike, however, this is rarely the case. Thus, the best way to deal with a flat is to simply not get one in the first place. How do you do that? With a seat belt, of course.

Now, it might not make a whole lot of sense to use a seat belt with a bike to prevent flats, but stay with me for a moment. The reason that your tire gets flat is not because the rubber on the outside is punctured. Rather, it is the inner tube contained within that rubber that is being punctured and causing the loss of air pressure. So what you can do is take an old seat belt and use it to line the inside of the tire before placing the inner tube inside. Since seat belts are so tightly woven, they can stave off a lot of sharp objects that might otherwise ruin your pleasant bike ride.
