Maybe the European market is different than North America?
What I see happening in mtb ebikes:
Group one: higher power ebikes sold for general purpose riding and as alternatives to motos. These bikes can be heavier and relatively less expensive because this market group doesn’t care. These bikes will have more range, torquey motors, and full throttles.
Group two: low power ebikes for mountain bikers who want assist, but also want a true mountain bike that is agile, has quality suspension, and is not heavy. These bikes will be more expensive because light weight and high efficiency cost more. In this group I expect to see bikes with removable motor and battery system. Throttles for walking only.
Group three: emoto, high power, throttle, nuff said.
There will tons of in between of course, the industry will have to fumble its way along the path as buyer preferences mature.
