Good points brought up on the video. I have talked before about my old Mongoose hybrid that I installed a front hub motor kit on. I really liked that bike but the Adirondack hills were getting harder to climb as I got older. The kit was all inclusive and installation was straightforward. The bike has front suspension so I opted for the torque arm, just in case, but the wheel has never loosened up and the fork is solid. I have put about 2700 miles on the bike since installing the kit and can say I still enjoy riding it. One of the best things about it is that the bike only weighs about 35 lbs. w/o battery, which makes it easy to lift onto the hitch rack, and if the battery or motor should die, it can be easily pedaled to get where you're going. I like the Aurora as well, but at 56 lbs. w/o battery, it is one heavy bike, and a bear to lift.
