Left side drive

why only stick at left hand drive. I've often pondered building a bike with duplex drive, ie with a chain on both sides. A standard hub with two fixed sides ought to work, and then the load will only be half on each side.

Sounds good huh? Anyone willing/foolish enough to try it?

Now this is pointless. Have you ever had troubles with having an unequal load on your bike? You'd also get chainline issues x 2 especially since most bottom brackets are asymmetric.

To the original poster: as you've already said, your pedals will unscrew, and you may struggle to find a bottom bracket which fits.
