Anybody find a fix for this yet?
I'm having the same problem. I sent an email to Wallke, & specified how the W-PAS regen feature is talked about in every review of this bike, they even wrote about it in my manual. So we'll see what they get back to me with... but to say our bikes simply don't have that feature is unacceptable, that would be false advertising.
In the meantime, I have half a mind to take my X3 to the one e-bike shop in my city, and see if I can get any answers there... I wonder if the speedo is cause of the issue, and getting that fixed will get our battery regen fixed as well. Really hoping its simple. Its always annoying when things don't work the way they're supposed to fresh out of the box. Especially when they were expensive to begin with...
