I think with the correct marketing & options, those modules would certainly sell well to guys getting into the e-bike world.
The annoying thing for me is that in the UK, we are limited to 200watt motors ( 250 for tandem/tricycles ) & 15mph on the road; offroad/on private land there are no limits. Given I weigh between ~170-220lb ( I'm getting down slowly but surely ), a 200watt motor and steep-ish hills is kind of a deal breaker; ofcourse, I also have no morals and the local police are near non-existent, so....
