Sweet God, chain that beast. If Frankenstein's monster rode a fix that'd be it. Sweet build man.

If I put the shifter on the left it would look weird...can't have that! ;-)

2) Sturmey-Archer hubs tend to upshift easier than they downshift, this has never happened to me, though the opposite has. The jumps aren't so big anyway--the "C" in "ASC" stands for "Close ratio."

Left hand drive sort of reminds me of an idea I once had — is there any benefit to having a dual drive bike? I mean, I could set up the chainline ok on both sides using identical drive-side cranks, etc., jb weld the cog on the left side (or something) but is there any benefit to this except satisfying curiosity?

The guy who did this did it mainly as a hack.
At the Paris bike show in 1988, I talked with a guy who had a booth full of dual chain bikes like this. Most of them were single speeds, but he had built a 10 speed where the left and right derailers were synchronized to operate both sides from a single shift lever. Looked like a LOT of work, manufacturing backwards derailers and a backwards freewheel body.
He claimed it was "much more efficient" but my opinion was that it was merde du boeuf.

should be a centerpiece for the sheldon brown museum. i just looked at all the close ups and it is one cool funky ride. it's an s.brown masterpiece of mad bicycle science for sure. always outside the box.

I was talking about doing the dual drive fixie earlier this year on the forums but never went ahead and did it... oh well. If you skid the back wheel on a Sturmey ASC do you strip it out?

My roomate and I have had conversations about building 3 speed fixies and left hand drive fixies at separate times, but leave it to Sheldon to combine the two and actually go through with it.
Ya know what we also talked about... a 2 wheel drive bike. We still have no idea how we would even begin to try to make it work, but it's an interesting thought.

Don't bother, it exists. KTM, I think. It's crap, of course.
Didn't find the KTM they basically made to promote their 2WD motorcycle they sent to the Dakar Rally, but here's some other 2WD madness: https://www.spicercycles.com/index.cg...0drive%20bikes
