Subject: Why is the Drivetrain Where it is?

I did a peremptory search of Sheldon Brown's site and the topics here, but
didn't see an answer to this question: why is the drivetrain on the right
side of the bike?  Is there a mechanical reason, or a cultural/traditional
one?  Am I overlooking an obvious reason why it wouldn't be on the left?  
I'm just curious, and have a limited knowledge of bike history, so help a
brother out!

Right is right, and left is wrong?

Actually, I'm quite sure it's entirely arbitrary. But now that it is what
it is, that's likely how it will be for quite a while, or at least until
the folks at Shimano decide otherwise.

It has to do with Coriolis force.  You'll notice bikes sold south of the
equator have the drive train on the left.

Threading, folks, threading. Generally better for things to get
tighter than to fall off while riding.

At some point de facto standards acquire such power even the likes of
Shimano can't change them.  Didn't Shimano try to change the chain
pitch?  And how'd that work out for them?  Likewise, didn't Shimano try
to change the shape of the chain ring from round to oval, with similar
lack of success?

I think the drive trail will be on the right until Hell freezes over.

Couldn't you just use left-handed threads?  Maybe you're right, but the
reasoning isn't as rock solid as I had hoped.  But it's pretty good.  I was
thinking it might be a prejudice against left-handed folks.

Long ago, I heard the explanation that folks were accustomed to mounting a
horse from the left and thus the drive was put on the right side of the
bicycle.
On reflection it seems that would really only make a difference to
equestrians taking up cyclocross

Subject: Re: {BL} Why is the Drivetrain Where it is?
I pulled out my copy of David Herlihy's _Bicycle_ and leafed through
the pictures. Most of the early chain-driven bicycles (safeties and
some chain-driven ordinaries) have the drivetrain on the right. An
engraving from 1893 on p. 270 shows a left-side drive bike, but it's
not necessarily drawn from life. If I recall correctly, Vélocio (Paul
de Vivie) had a bicycle with a drivetrain on each side to permit easy
gear changes in the pre-derailleur days. My guess is that it was due
simply to the inertia of tradition: once Henry Lawson and John Kemp
Starley had introduced their safety bicycles with the drivetrain on
the right, others probably just followed suit.

It seems to me that since most people are right handed, they are also right footed as well.  This means that their right foot/leg is the more powerful of the two.

It would make sense to keep the driveline on the right side since that position is more in line with your most powerful stroke and perhaps lessen stress on the bottom bracket bearings.

That said, I'm betting on the mounting a horse from the left side theory.

To put the drive on the left the freewheel threads on the hub would have to
be backwards for no good reason.

Subject: Re: {BL} Why is the Drivetrain Where it is?

I have read, do not know where that the drive is on the right side of a
bicycle because most people are right handed. Therefore their reaction in a
fall is to protect the right side of the body. This means that in a cash
the left side of the bicycle lioke the left side of the body hits the
ground more often thus having the drive on the right protects the
components from damage in a fall.

While there is some apparent logical sense to that I have no idea if it is
true or not

This hypothesis assumes you have control in a crash which way you fall,
which is probably only very rarely the case.

Funny on several of my BMX bikes, I can set up the cranks left or right
side. I could even run a double drive train. Now that would be cool. a nice
36 - 13 on both sides.

That's so you can put your drivetrain opposite the side where your pegs are
so you don't bash it into ledges and handrails. Actually has a good reason.
If you've spent any time on fixed gear sites you might have seen people set
up their bikes left hand drive to be cool. Sound in theory I guess, but I
just stripped the lockring threads on my fixed gear and it was set up
properly, so I wouldn't want to risk it.

Some rental tandem is China have chains on both sides to rear wheel.  They are single speed, with freewheels on both sides of the rear wheel to provide independent pedaling.  On the ones that I have seen and ridden, the chain from the captain's cranks is on the right side and very long.  The stoker's chain is on the left.
