I am ordering a wide crank pedal set, just trying to figure out which way i wanna go, bent cranks or long shaft etc.................so no, not now, i just use them as a rear brake. I had to cut the rear frame tube to allow the chain to fit thru. If you look close you can see where i used 1" aluminum square tube to brace where i cut it, right behind the lock pouch on the left side.
That bike is unsafe to ride with the frame cut like that. The reinforcement you did is nowhere near adequate. I would have instead constructed a jackshaft so that the chain would clear the frame.
A Jackshaft would not have made a difference, there is simply not enough room there either way.
This is the most negative forum i have ever been on.................
