Hello all. I've had my RadMini since Christmas, and I'm really loving it. Not loving that it doesn't have a cage for a water bottle though. Couple that with the need to carry stuff and I decided to get a bag for the rear rack. What I did not realize until after receiving a nice bag from Amazon was that most bags won't fit on the rear rack. The straps are just too short for the big beefy rack that comes with the RadMini. I went through every bag that I saw on Amazon, and while a few did look like they may work, those that may fit didn't have a water bottle holder. I opened up my search outside of Amazon, with the same result. Finally went to the largest bike shop in the Orlando area, and found a bag that worked. The KoKi Rover trunk. Really nice medium sized bag that fits the RadMini rack like a glove. Now, you may have to search a bit for it if you are interested in one, because they may have discontinued it, but if you find one it will make a nice addition to your RadMini.
