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
So a double crank will require a way to shift (i.e., gearing), thus you introduce a
derailleur ....Isn't that a multi-geared bike then with at least one half of the complications of the conventional multispeed bike with a
front derailleur and a rear derailer?
