I've been pondering the same idea.  I'm sure there will be many disagreements in what is the perfect commuter bike.  I've been them looking at them a lot lately including a very nice three speed at REI.   Of course this is out of the specrtum of the goal but a good starting point.

Remember the 100 dollar mtn bike frames Nashbar sold a few years back?  I imagine something like that with a basic set of components.  Flat bars.  Single chainring.,  6-7-8 gears in the back.  700c 32 tires.  all else simple yet functional.
 
hmmm..

I'm starting to think now about what the minimum cost of a new bicycle along the lines we're talking about would be... It would take some research but with a decent cheap steel frame, the rest could conceivably fall in line for around $100-150, could it not?  With a little work and some fine tuning between this think tank, maybe we could get something rolling and in each of our respective neighborhoods start actually competing.  Thinking about here in Austin, a hopeful starting point is that we're better positioned (geographically and in the community) than any walmart to offer or promote such a bicycle to people who need bicycles. 

What about build kits even, along the lines of ronald's comment?  Save on the labor-intensivity of this kind of project on one hand, and offer people a discount for building up their own new bike, helping them along the way and teaching them the repair skills they should know for their new bike?

Agreed. I actually meant road bike, it is 9:30 pm here in italy and I
have been drinking. Also, my fingers sometimes make decisions my mind
is not aware of.

I do not think most people need all the gears. When I ride around in
the city I use my fixed gear, because really that it all I need. Never
had a problem. when I go for longer rides, I take my road bike,
because I may like to be able to shift into lower gears for wind or
hills or higher gears for straights and particularly downhills. Of
course I am talking in the past tense, since I only have the one
geared bike in italia.

Again, I think bike collectives can be useful because people can get
an actual good bike used for less than the cost of a cheap crappy bike
at wal-mart, and they can learn how to maintain them and therefore
also save on expenses in the long run.
