I sometimes get questions about what kind of gas engine it is or if the gas engine is in the big cargo pods, on CrazyBike2, cuz i has part of a handlebar tube sticking out the back on the left side as a place to clamp the bicycle trailer to. (until I can replace that with a regular car/truck style ball hitch, which I have all the parts for just need time to do it since I have to modify both bike and trailer at the same time).
Since they can't see any other motor, they assume it must have a motor or a gas engine either under the plastic "fairing" aorund the frame, or inside the big metal cargo pods on the back. Very few seem to have thought of or heard of the concept of hubmotors, so they dont' notice the one in the front wheel.
Some think that is a brake (usually they say "disc" becuase maybe they havent' heard of drum types?) cuz it's big and silvery. Perhaps they didnt' notice the big bundle of wires running up teh fork leg....
I do still get lots of comments, usually one a day or so, while it's parked out front at work (not directly at the front of the store, but across from it; I can't handle walking it thru the store around all the corners these days, to get it to the breakroom in the back of the store, and I can't park it right up at the front wall of the store outside anymore, so it takes up one of the car spots across the drive from the front windows--usually the one that would give the most "shade" near sunset from the meager "bushes" there).
Most are positive, some are unsure, a very few are negative. (maybe one every few dozen).
At least once it has inspired a customer to now always ride her bike around for shopping trips to places within a few miles of her apartment, instead of driving her car. She's considering buying an electric cargo bike to be able to do more, further, cuz it would cost her less than the gas for her old SUV that gets a lot ess than 10MPG in city traffic!
