    Steep hills that strain the hub motor

    I am wondering if I need to be careful not to damage the hub motor or controller on my ebike by pushing myself and the motor to go as far as we can, up some of the steeper sections of the many hills in my area. The bike was sold to me as having a 350 watt brushless hub motor. The bike was made...
