Nice bike! I am myself considering the same exact model, but I have some doubts if the motor would be strong enough for climbing steep hills (12%)? The gears don't seem to be appropriate for hill climbing, so the cyclist's effort could be not effective.

Any thoughts based on your experience? You mention hill climbing, but what hills are you talking about? 5%, 10%, more? Also is it possible to climb hills on slow speeds (say walking speed) or on higher speeds only, as hub motors are not effective on very slow speeds?
