Can anybody figure out why bicycle chains or "drive side" is designed to be on the right hand side, while motorbikes are designed on the left?

Most engines are built to rotate in the same direction making it practicle for the chain to be on the corresponding side.
As far as a bicycle I believe that some tandems have chains on either side as well as some "motorized bikes".
As far as regular bikes I believe the design comes from the old standards that eveolved in the 1800's therfore they just haven't changed because thats the way it's always been, of course this part is theory.

I don't have the faintest idea why this is so.Bike_Tyson said:Can anybody figure out why bicycle chains or "drive side" is designed to be on the right hand side, while motorbikes are designed on the left?

If you are both bicyclist and motorcyclist, you probably have a lot of internal conflict. Sorry.

one_beatnik said:That's funny. Yep...do I ride the bike or the bike. It's very confusing at times!
Bike_Tyson said:I hope you ain't nit-picking. What I'm referring to, as we can see on the roads daily, and COMMONLY and generally, in the 21st century, most motorcycles have chains on the left side, bicycles on the right.
Oh, now we all knew you have a motorbike with drive shaft (not chain-driven). That's cool, congrats! can we move on?
frenchyge said:He's just giving you the honest answer to your question. There's no universal truth about motorcycles that dictates that the chain be on the left, and this is aptly demonstrated in the fact that some bikes drive from the right, even here in the 21st century.
As far as bicycles go, there's also no universal truth which dictates that the chain should be on the right, but as there's a huge incentive to have compatibility between frames and components I expect that's enough reason for manufacturer's to conform to a standard. With motorcycles, a single manufacturer designs and builds most of the components on a particular bike so there's less reason to create or conform to some standard established across multiple brands or even models.
jhuskey said:Well, I said most. Boat motors are built with right and and left rotation and I think I heard that Honda engines rotate counter to most. Even a car engine with worn cam lobes can definitely run backwards but no indefinitely.
