The short answer is yes. So far I've been to about 4, or 5 CM rides, and never had a problem. On occasion there's been as many as four eBikes at one time. A lot of people are always curious about our bikes so I spend a lot of time answering questions. I've also attended some other bicycle riding events around town without issues. I see some of the same people at these other rides, and they recognize me now, and are always friendly to me.
When I ride with bicycles I never show off, and always just blend into the crowd. Once the ride starts no one seems to notice, and there's good reasons for that. I always pedal. My bike is silent, and riding at their normal speeds, no one can really tell if I'm using power or not. On one ride someone actually ask me when I use the motor. He was surprised when I told him I had been using it the whole time. We had already been riding about 8 miles at the time.
If I was acting like an ass I'm sure it would be a different story, but that pretty much applies to everyone else too.
