The Bosch motor is the only one of the two I have ridden with and it has a truely irritating rattle from the engine when it freewheels, I’m not sure it actually fully disengages, but uses a sprag clutch like the Brose and it’s that we can hear much like the rear hubs when not under load.
Whatever, it is almost academic with the TSDZ2 motor, it is what it is and has two sprag bearings, yes they are going to have some drag when the motor is off, but do we really care. From experience I have had only ever had to cycle home twice with a dead motor ( both times water ingress related ) and it is more the fact that we use a much larger front gear than an analogue bike, that makes it feel as though you are riding an overweight over geared tank.
