I had just the opposite experience the other day. A very long time hard core semi pro local cyclist (his wife too, in fact especially her) needed some trusses set on his new shop, so as we've known each other slightly for 30 years or so (from the local ski area, and it being overall a small town) he gave me a call. Point being, we don't hang enough for him to know I have gotten way into e bikes, so after I got the crane setup but before we went to work, I made a point of opening up the compartment I keep my crane's e bike in, and also telling him about my other 2 e bikes and my most epic recent rides. He seemed mildly interested but exhibited zero animosity towards the concept.
If he had, I was prepared to tell him to get someone else to lift the trusses up! Not really, he's a good guy and I didn't really expect to get dissed. I have yet to get a negative, in your face type dissing out in the real world, only online by key board tough guys, and they don't count. Then again, I rarely mix with others when riding, the few times I do I keep moving (at a "regular" bike speed), say hi, nice day, blah blah, and move on. Now dirt bikers are a different story, with them I'll make a point of telling them all about what I'm riding, and usually pull a wheel stand when taking off at a high rate of speed up the trail they never see any other bikes on as it's too gnarly.
