I changed my freewheel on my Aventon Abound to a 7 speed with an 11 tooth on the small ring rather than the 14 tooth to reduce clown peddling when traveling with the throttle. Would a RadExpand 5 accommodate similar?
So I risked it on my own since no advice here
The Drift Maniacs 34/11 seven speed freewheel was a direct replacement without requiring re-indexing or a long cage derailleur, I can now contribute by peddling - even at full speed where the motor back-emf starts to inhibit.
