A year or so ago I bought a beat up old bike at the local thrift store for twenty bucks. The gears didn't work, so I took the cables off, making it a one-speed. The front brake was busted, so that went, too. I found that if I rode the bike for more than a few minutes I got a stiff back from leaning forward all the time to hold the handlebars. So I used some scrap PVC tubing and a couple of PVC tees to make a handlebar extension. Now I don't have to ride hunched over when I'm doing some easy pedaling on a straightaway or downhill.
Step 1Attaching the tee to the handlebar.

I took off the rubber cushions from the handlebars (A little WD-40 helps). Then I drilled a small hole through the handlebars about an inch from the end. I drilled the same size hole through one side of the tee fitting. Then I used a nut and bolt to attach the tee to the handlebar. It was a little wobbly, so I wrapped some electrical tape around the handlebar until I could just barely slide the tee on the bar. Make sure that the angle of the holes is the same for both sides. Mine is a little bit off, but it doesn't seem to make too much of a difference in the ridability of the bike.
I've biked from Mexico to the deep south of Chile with straight handle bars and often thought about having a 2nd identical handle bar "hoovering" about 15 - 20cm above the normal one. A bit like this guy: http://en.wikipedia.org/wiki/Heinz_Stücke (which basically proves you right imho)
It is what makes drop bars on a high rise stem work: multiple hand positions in the vertcal plane. Not to relieve your hands from too much weight (in that case your frame is too small, the stem too short or the sadle too close to the handle bars), but to change between "checking the scenery" and "dodging he wind".
To BobS: I like the clamps that hold your pseudo aero bar extensions. Might also be the perfect solution to mount 2nd handle bars safely.

the reason handklebars require an end plug, it that bar can get into your guts without it
it becomes a gouging tool that is deadly,as would broken pvc,
if bikes were like cars, your rig would be pulled over by Highway Patrol
I live on a ranch where everybody rides super slow and casual without helmets wearing sandles and whatnot
guess I'm too clutsy of a rider for all that
its shoes, gloves, helmet, and no kids on without...
in my paranoid world, just don't like blood. Carefull
nice design get some aluminum!! Nico
Race bikes have nowadays extenders to lean even more forward. I used them to make something similar for my http://www.instructables.com/id/Bicycle_Front_Transport_Carrier/.
