I am a petite ( 5'1") woman currently on a Surly which I love but am interested in buying an ebike for the steep hills in my neighborhood in Los Angeles. My wants: upright position, commuting and touring ( 60+ miles), removable and lockable battery and computer, quiet,comfortable ride with panniers, groceries/small dog, lights, rack, great brakes, step-thru, phone charger, good warranty, easy to repair. My budget tops at $3,000. Due to the hills, I would appreciate your thoughts on pedal assist only and pedal assist w /throttle. I plan to use it as my car replacement for the next three years. Any advice is appreciated.
