More niche ebikes I’d say.
There’s one corner of the market that seems quite under explored - ebikes for riders who just want a bit of help.
Not all want the 1000W motors and the huge and heavy battery pack turning the bike into something else.
I like riding.
Don’t want a thinly disguised moped.
For unloaded or lightly loaded city/urban riding - and My fondness for pedaling - I don’t need high watt motors.
I have access to sockets both home and at My destination, I don’t need a huge battery capacity.

But 2x16 miles of commuting, particularly during winter conditions - meaning studded tires, inches of snow/slush etc. is quite tiring.
I’d like to see ebikes nearly indistinguishable from regular bikes, built for riders who only want a bit of help.
I’m guessing, but 50W extra consistently would probably do wonders for cancelling out the influence of snow and heavy tires. It’d be like summer riding all year.
And 1-2 hour battery life would do me fine.
With a design that doesn’t cause drag when unpowered, an ebike like this would be rideable/enjoyable even with a flat battery.
Someone else might use a similar setup to be able to ride with stronger riding buddies.
Or maybe a clean-looking SS with hill- and takeoff assistance ”only”. No E-cruise ability.
E-bike folders that don’t get too heavy to carry.
