What kind of motor then? Wheel hub motors are sufficiently large that you could recognize one from meters away. There are only so many places to put a motor on a bicycle and at some point you have to come up with an explanation for what happened that doesn't involve a motor.
- mikeyouse 10y agoI'm not saying that's what he did, but they have very clever (and expensive!) electromagnetic wheel motors that can provide ~50W of power for extended periods that likely wouldn't impact the pedals. http://cyclingtips.com/2016/02/electromagnetic-wheel-motors-possible-in-theory-but-unlikely-in-practice/ http://cyclingtips.com/2016/02/electromagnetic-wheel-motors-...
- guyzero 10y agoThese "motors" aren't expensive, they're completely theoretical. There's no proof anyone has built a frame-rim reluctance motor anywhere ever. The linked article literally says "So, is an electromagnetic wheel possible? Yes, in theory" and has no concrete examples of one ever having been built.
