I don't understand why people are always trying to reinvent the wheel with a single/fixed drive train. The whole point of it is its simplicity and reliability.
The pulley I mentioned is not a chain tensioner i.e. it has no spring and no cog, it's just a pulley/chain guide. The chain cannot pull/push it because it has nothing to grab on to.
I do not want to reinvent the wheel but to keep simplicity. It seems simpler to have a double crank and a pulley than to flip-flop a wheel.
Unfortunately my fixie conversion project has changed to a restoration. So I won't be able to test my theory.

true. To grow old making money by doing what you love. It's a nice dream
