Not only don't climb hills they retard your effort to ride faster than about 25 kph as you end up pushing against the motor
ive had this ebike 3 days and im returning it as a it is next to useless.
Back to my road bike at least i can go faster than 25 kph on it.
Also something noone has mentioned they warn you not to ride Ebikes in the rain thats great if you live in Melboune
and get caught in a sudden downpour.
I've never had to push against my motor when I go faster than it will propel me. It's just the same as freewheeling on a normal bike if you are going down hill faster than you can pedal. When I coast down Welshpool Road hill of my "big" trike I hit over 75 kph, then on the flat I can keep cranking (no motor) for about a kilometre at over 40 kph, and only have to slow down to turn a sharp corner.
As for rain ... I've had one e-bike for about 5 years and absolutely no problem with the rain at all.
