Okay ... so I am doing pretty well in tearing these bikes apart. Unfortunately, there are not a lot of them out there with 3 piece cranks that I can find, or big hub BMX bikes. Are there any suggestions or modifications in which you can use a single piece crank or these 20" front wheels that are beginning to multiply?

You can use a single-piece crank without modifying anything, as long as you also use a bottom bracket shell it fits into. The only thing wrong with single-piece cranks is that they are (1) heavy (2) will not accept as many screw in pedal options (different size thread); (3) usually harder to change sprockets than good BMX spider type cranks.

Has anyone thought of taking a couple of front wheels and making them a tandem? Wouldn't that give them pretty good strength together?

I could forsee friction and steering issues.
