Screw on freehubs

[Retrorockit]

We see ebike freewheels every day now
Believe me:
You don't want that sh1t on your bike.

It's definitely not on my bikes. I don't have any freewheel hub bikes. I'm only on the mid drive Ebike forums so no feedback on those things there.
I found some White ENO Ebike freewheels at 1/2 price on Ebay and went with one of those for my front freewheel project. Completely different materials and design. The Chinese stuff is in my junk pile. I suppose multispeed doesn't improve them.

Grin Technology in Canada are the hubmotor experts. You might ask them or in in their forum if there are any good multispeed freewheels out there. They're engineers, not just parts vendors. They would certainly have relevant experience with these things. Maybe they just use Shimano 13t stuff?

Is it something like this you’re trying to add a cassette to?

I'm seeing Shimano Tourney 14t freewheels for sale new, in a couple ranges.
The 11t freewheel thing is to support the higher speeds Ebikes go.
I swap out my cassette and worn chain on the Ebike as a pair. Cost of doing business.
Maybe the hubmotor guys are swapping them out too just like I do.
But there is a market for new freewheels for Ebikes . I think you can find what you need there.
