it depends on the amount of heat, if you get it hot enough you heat treat it which makes it stronger, but if you don't get it that hot (or get it that hot in one point, but cooler around it as a torch does) you are weakening more then you are strengthening. Also bike tubing is quite thin, and easy to burn a hole through if your not careful, or don't know what your doing.
