I have this on my tricycle and want to transfer it to a single-speed bike.

But I don't want the coaster brake.

Is there any easy solution to this?

Thanks

Or is there a way to purchase an internal with a freewheel sprocket?

take it apart, remove the reaction arm, that connects it to the frame ,
perhaps..
No personal experience having done this, to that product.

Internals gear hubs incorporate a freewheel mechanism in them,
then to change the gearing range, all you swap is 1 sprocket,
typically held in place with a snap ring.

Most 3 speed hubs have the spline in common, by now,
3 tabs in sprocket, following standard set by Sturmey Archer 100 years ago.

Why are you using a three speed hub to build a single speed bike? You might be better off going with a non internally geared hub with a standard single cog freewheel.

Do you have an example of this? I've never head of that.

I read OP as putting a 3 speed on a single speed frame,
BTW, the dropout width is what in the 2 wheel bike?

I'd just leave the 3 wheel trike alone.. buy/build a different wheel
for the soon to be 3 speed bike.

Yeah, that's the conclusion I reached in the past few minutes as well. The part on the trike is 89 bucks, and in the time it will take to remove, fix the trike, apply it to a single-speed bike, and all the hair pulled out, might as well scrap that idea.

Thanks, folks.

Now Shimano IG hubs, like, go to 11 [speed].
