Which electric bike for a small mountain?

I can't see how such a tiny cylinder is supposed to generate torque to go over a speed hump let alone a 30 degree hill which will make 8 inch diameter motors overheat in a matter of seconds.

the lack of system ventilation forces the designer to leave the motor core exposed to mud and water ingress.

quite the opposite. Push it and the power to the motor is cut.
It's for bikes that can't have brake sensors.

Oh dear, sounds like braking is an elaborate maneuvre on such a system. Talk about dangerous.

That's not what it's for at all. is just a switch to switch off your motor when you want, instantly, like when you want to change gear without crunching, or negotiate a pedestrian infested zone.
