I like the idea of 2 motors as I live at the top of a hill - end of a mile long road climbing about 800’. I’m about 260lbs. and my wife is around 135 and she’s quite afraid of riding her own bike. I would seriously consider the stretch if it could get us both up the hill with moderate pedalling. I wonder what the combined torque rating for the dual motors is? Also, what’s the suggested range? Finally, can one of the motors be turned off for riding on level ground to extend the range? (I did a test ride with my wife on the back on a level zero grade, lakeside rail trail - about 15 km total at assist 3 and more than enough power for both of us)
