Bikes: A brand new Trek cyclocross and a very old Schwinn road bike with a long interesting history. Ask me if you want to hear the whole story.

Left Handed Bikes
I think someone should make left-handed bikes, with the chain rings and everything on the oppisite side. Because I am very left handed , I generally dismount and handle the bike to the right, often ending up with greasy legs.

It's gotta be tough living in a backwards world...
Though I dont know much about them, may I suggest a chainless bicycle ?

Fixed gear bicycles can be assembled either way, right hand drive or left hand drive. But since no one makes backwards freewheels, I don't think there is a way to do it on a 'regular' bike.
I recommend a chainguard, one of the most useful inventions that no one seems to use.

Either way I'd hate to have a pedal come off on a fixed gear!

I'm lefty. I mount from the left. I hold the left bike handle with the left hand and the saddle seat with the right. I pick up my right leg and swing it over the top bar. I put my right hand on the right bar. I proceed to bike. Should be even easier if you have a woman's bike. Probably the young'uns have a sportier way of mounting than that. In any event, it doesn't seem to require the fine motor skills that left/right handedness tasks like writing would.
Then again, I'm nearly ambidextrous, so maybe there's something I'm missing.
According to Sheldon Brown's logic, lefties should have an an advantage since bikes are wired with the strongest brake on the left side. But I signal with either hand, figuring that motorists won't have a clue what an upraised arm means.

I've gotten to the point where I can mount comfortably from both sides. Its a good skill to have. I mount a little better from the left side, but both work. I can even mount and dismount from the back on the fixed gears, and have occasionally dismounted off the front (unintentionally ).
The pedal threading issue for 'left hand drive' fixies isn't a big deal. If you think about it, the threading on a regular bike is set up to loosen the pedals as you ride! This doesn't matter because the force of friction that the bearings exert on the pedal spindle is no where near the force of friction holding a well tightened pedal in place, but its one of the reasons pedal wrenches are so long, you need to get them pretty tight to begin with, in order to prevent them from popping off! But of course, that is easier than the opposite threading situation, where the pedals will tend to tighten themselves a bit. So if you do left hand drive, you won't have a problem with pedals coming off, but you may have the smaller, but annoying problem of having incredibly tight pedals. Just get a good coat of anti-seize or grease on the threads, and pack a big wrench.

Left handed people like us are the superior race. Even though I use my PC mouse right handed, and a few other things, everything else is left handed.

"The right pedal has a normal thread, but the left pedal has a left (reverse) thread.
The reason for this is not obvious: The force from bearing friction would, in fact, tend to unscrew pedals threaded in this manner. The fact is, however, that it is not the bearing friction that makes pedals unscrew themselves, but a phenomenon called "precession".
You can demonstrate this to yourself by performing a simple experiment. Hold a pencil loosely in one fist, and move the end of it in a circle. You will see that the pencil, as it rubs against the inside of your fist, rotates in the opposite direction."

I built my fixie left-handed (by mistake: was doing it nekkid and wanted to keep the transmission away from my knackers!). It ran fine but looked weird - as weird as a single-side fork or other freakbike stuff. Nothing unscrewed, but it was all done up tight and I'm a bit of a threadlock ***** these days. The one problem: I have Time ATAC pedals and I couldn't clip in 'cos they were facing backwards!

Careful of the chainring, it's not just dirty, it's sharp too. Just learn to mount and dismount from the left. I'm lefty and that is what I do. In fact I always try to stay on the left of the bike to avoid the dirty side.
I would think switching the shifting and braking to the opposite sides of the handlebar would be easy. No?

Left handed threading on left hand pedals was a Wright Brothers invention. Before that, there was a tendency for the left pedal to crank itself off in time.
Right side freewheels/sprockets came about because with right hand threads on the freewheel and hub were standard and did not require the extra tooling cost for making left handed theading as would be needed for left side freewheel.
There are bmx hubs and single speed freewheels available with left hand threads for left side mounting.

Why? Just because BMXers are an ornery bunch?

Wouldn't it be easier to just dismount to the left? And use a dry chain lube?

I noticed that when I was watching his BMX trick tips video. If I remeber correctly he grinded left, and di a few other things lefty, the 180s and stuff like that.
