Anyone else experienced things coming loose on e-bikes that never happened on non e-bikes?

I’ve had a spate of stuff loosening that I’ve never experienced before. Side stands, crank bolts, the latest is a cassette lock ring! I can only put it down to increased / different vibrations caused by the electric motor.

I’ve always been wary of over tightening bolts and have been a big fan of copper grease, but I can see loctite in my future!

Not in my case (crossfire e).
Properly tightened bolts and nuts should survive vibration and I cant think the normal vibration from the motor etc should cause trouble. Which makes me personally wonder...is it a bike assembled at the factory by someone who was being less than conscientious.

Not me or mine either. My better half sometimes thinks I've gor a screw loose when I've gone for ride in the depths of Winter, but in two and a bit years of use my Orbea Gain has stayed a screwed together as any of my huff & puff powered bikes.
