Regarding shipping fees, when I purchased  two Rad Rover 5s, I called them to coordinate my Veteran discount ($200 off each bike!). I also wanted to order the rear racks at same time (with free shipping) but they were out of stock. They graciously made note in my account, notified me when the racks were back in stock and then provided free shipping based on my initial bike order deal. Can’t beat that! Sometimes talking with them helps!
