I like being able to see behind me so mirrors inside each handle bar was one of the first things I bought. A padded seat was the next. The bikes came with saddlebags, but they were a little small so I bought larger ones so I could do some grocery shopping on our trips. I have been shopping on the scooter so it is very much the same. I can load the saddlebags, and clamp some bags onto the seat behind me, resting on the back rack. The bike does not allow me to have something in front like I'm used to, so absolutely no watermelons on my lap while I drive. I only did that once, and will never do it again. It was work to drive, stay focused and get the watermelon home.
We also bought a hitch bike carrier that we can lock down so we are not concerned about leaving our bikes out over night. I bought a barbecue cover and it goes over both bikes nicely. We have motion alarms so that when we park the bikes and go inside we can lock them with a huge chain like lock but also if the bikes are tipped an alarm goes off. The biggest problem with that is that I keep forgetting to turn them off while we are traveling so we often go down the road with the bikes blaring and us totally unaware.
The bikes are an investment I hope Dean will enjoy. I am really looking forward to getting some exercise on our trips and seeing if it can help my health. I hope to return home from the trips this summer, a little stronger and a little skinnier.
