IMAGINE
THE FREEWHEEL INSTEAD OF A RATCHET IS A SPRAG
AND IT ONLY LOCKS ON SYNCHRO
SO
UNLESS YOU'RE PEDALING A CLOSE ENOUGH SPEED, THE PEDALS ARE UNLOCKED AND YOU'RE SPINNING A ROTOR IN A STATOR, AND AN EBIKE MOTOR PUSHES FORWARD

AND IT COULD BE NOT IN THE FRONT SPROCKET CRANKSET BUT SOMEWHERE IN THE DRIVETRAIN
