Roger....many of these e-bikes have an 'auto' display setting...I have customers who think that 'auto' means that the PAS will automatically select the correct power setting according to the load on the motor...interesting idea but thats not what it does.I don`t use the throttle for riding but when a nasty hill and low battery power coincide , I hop off and walk alongside and use the throttle to drive the machine up at my walking pace to conserve what power is left . It would be a shame to lose this facility because of some non Ebike riding Bureaucrat .
It allows the bike to travel along at 4 mph without turning the pedals,its actually a nice facility to waft along on the flat or very gentle incline at 4 mph,its really a nice thing to do on a nice day and admire the scenery(pervy thoughts ignored)but it does have another use and I suspect why it was first invented-you can walk alongside and the bike will carry itself along at 4 mph,this is particularly useful up very steep hills-at least the bike will carry itself up the hill. Its also useful for walking alongside a companion and not pushing the bike.
However be aware that you then need to walk at 4mph to keep up with the bike.
