Probably a different type of motor. If you watch the video the back wheel slides along sideways for a while. This would stop all usual motion of the wheel and there is no way that it would maintain sufficient power to move the bike as it does even if there was some residual rotation.
- guyzero 11y agoWhat 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 11y 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 11y 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.
