We recently bought a RadRover 6 Plus Step Through for my wife. I recently took it for a ride and 'tested' it on hill climbing. The hill is very short (75 yards) but steep for about 30-40 yards. I was shocked that it could not make it up this hill in Pedal Assist 1,2, or 3 (not providing any 'help' from pushing hard on pedals)! In PA 4 it was straining but made it! However, with throttle only, it goes up the hill fairly easily. Then I tested my Aventon Adventure on the same hill. This bike pulled strongly up the hill in PA 1. In fact, it pulled up the hill better in PA 1 than the RadRover in PA 4!

Does this power level seem normal for the RadRover? The difference between the two 750W bikes is massive. I contacted Radpower and they suggested 
certain tests and checks which I did but found nothing wrong. I have not gone back to them again yet, I just would like some input from some other owners with more experience with the RadRover. Any suggestions or opinions?
