Ok I'm somewhat familiar with bikes, cause I like to build motorbikes.

But what i dont know: what is needed to change a single speed freewheel to a 7speed freewheel on a hub motor.

Are ebike hub motor freewheels a special thread size & pitch?
Any special offset?

I know I'll have to come up with a way to mount a derailleur, but that should not be a problem.

Any professionals out there want to give me some help/info?

Thanks all help appreciated.

It almost looks like your single gear screws on. I would consider trying to unscrew it, and see if a standard freewheel cluster can simply be screwed back on.

Well I considered that, but I figured I might save some time by asking someone if there was anything odd on a hub motor freewheel. But yes it threads on the hub motor.

I need to purchase the socket/tool to remove this single speed freewheel. I think I got enough space for 1, but maybe not.
