Yeah, linniej is right on. The turn signals and lights are solid but the bike is ~125lbs so even with the larger 500 watt motor and 48 volt battery it's a bit harder to climb (and pedal to help). The other thing is, it only has one pedal speed so other lighter bikes with lower gears feel easier to climb with than this one. Worse case you could hop off and throttle while you walked next to the bike and pushed but that would only be on very steep hills or if you had to stop half way up a hill. If you go into it with some speed you should be alright.
