Suicide hub is a single threaded hub with a cog glued in with LocTite, Because without the LocTite it would unscrew its-self with ANY backwards force.

If you know how to build wheels, a good, cheap flip-flop hub would be: http://www.irocycle.com/iropremierrearhub.aspx
If not, look for a cheap wheelset/wheel online. Eigthinch Amelias are the most common cheaper ones you will find, running 99.50 a set, with a tube, tire, cog, and lock ring, but they aren't the Best set. However, they have lasted me so far!
But right now I'm building up an IRO set (technically Formula hubs, and Velocity Fusions under a different name) Look for other peeps to give better ideas and things. I'm not that great...
