I had a flat one day after running over a pin and had buy new tubes. I continued to have flats with the 4 succeeding Bell tubes I bought. The tubes say three speed only, does that affect it? If not what could be the problem?

You might have something stuck inside the tire that caused the original puncture. If it's still there, you'll keep getting flats until it's removed. Next time you change or patch the tube, check the inside of the tire for anything that might still be in there. Also check your rim tape to make sure a spoke isn't poking through.
Sometimes if the tread on your tires is starting to wear thin, you'll get more flats, too. If the tires you have on now are old, you might want to replace them too.
As long as the tubes are the right size, the fact that they say 3 speed shouldn't matter.

If the tubes say three speed only, they are probably for 27 inch wheels. Perhaps having to fold the tire to install them is causing flats. I highly doubt this. Just conjecture...
There is more likely something stuck in your rim. It could be a piece of glass, piece of metal, or anything really. The next time you remove a tube with a flat, try to reinflate it and see where the hole is. Then match the hole up to the spot on the tire where it happened. Also check the rim. If your rim strip is out of place, or there is a rough spot on the inside of your rim, it could have the same affect.
Finally, make sure you are not pinching the tube when you install it. This is a good way to have flats very often.

ok, firs mistake: Bell tubes. buy tubes from a bike shop, they cost about $5 each. they are made from a higher quality rubber and are uniform thickness unlike the bell tubes.
make sure the tires are pumped up to the proper pressure. i have my tires at 60psi and i run over glass all the time and i have not had any problems in several months. look on the sidewalls of your tires to find the recommended tire pressure.

Well maybe you aren't thinking outside the box. After replacing the tubes and filling them, how many PSIs did you put in the tire? Anything over 40ish PSI is too much. The tire will burst and sometimes the burst is delays a few mins after you fill it.
