Is the question "Have already", or "want to have"?
If the latter, then yes, if the former, then no.
I have to redesign the drivetrain to put a clutch on the rear wheel first (like that off an AC compressor in a car, but operating in reverse so it's always engaged unless power is applied or the mechanical linkage is operated), move all the shifting forward of that into the frame, so that I can use regen braking on my motor and still be able to coast.
