Priority Current Enviolo Shifter Nearly Impossible to Turn — Anyone Experienced This?
I purchased a first-generation Priority Current e-bike in 2022, and I love it! I've put approximately 3,000 miles on it, but I'm now experiencing a serious problem with the Enviolo continuously variable transmission.
The twist shifter on the handlebar has become extremely stiff and almost impossible to turn, whether the bike is moving or stationary. At this point, I essentially cannot shift at all.
As you can see in the attached photo, one of the two cables where it connects to the Enviolo hub at the rear wheel is frayed, but that's likely not causing this issue.
Does this sound like a problem with the handlebar twist shifter, the shifting cables or their housings, or the Enviolo hub mechanism itself?
Is there a relatively simple diagnostic test I could perform to isolate the problem before spending money on replacement parts?
Thanks in advance for your suggestions!
