I am looking forward to the delivery of my Rad Rover Step Thru, my first e bike although I have been at it for 60+ yrs. Its mainly hilly country here with a few mountains in the background. I have been using a tired looking round mirror left side in the past so I am seeking advice on a new one or ones providing expanded horizontal coverage. Something that is available on Amazon would good (free delivery). Thank You, Mirage (Lawrence)
