Chain tensioner On Pedal Chain
I don't like using the chain tensioner. They are one more thing to align and fail. So on my builds I shorten the motor chain and adjust the rear wheel to tighten the chain.... just like on a motorcycle. Unfortunately, there are some set-ups where, no matter what I do, either the pedal or motor chain is saggy loose.
Sooo, I got to thinking......
Rather than put the tensioner on the fast moving Chain-O-Death, why not put it on the pedal chain? The pedals get little use, and when the pedals are used, everything is moving much slower (at least in MY case).
And for those who hate the look of the stock tensioner, there are a bunch of fancy bicycle tensioners.
You gotta be smarter than the tool you use.
