I tried out the new Trek Verve+ today I liked the way it shifted and the smooth transition when assist kicked it. I tried it out here in Florida where I am on vacation but would be using in and around the Adirondack Mountains in Northern NY where it is quite hilly. Many of my rides there would be 40-50 miles but would usually be using the ECO assist level because I still like a good workout. I also live on top of a 2 mile hill so it would be nice to have some battery left at the end of a long ride. Also I plan to do some touring with a 30-40 pound load. I own two Treks now: the 520 touring bike on which I have taken several 600 mike trips. I love it! I also have a Trek carbon 5000 (not 100% sure of the model). Love that one too. I am 65 and plan to continue riding them but am wiped out after long (40+ mile) rides so I think the combo of both bikes would be helpful. Also looking at the Giant E+ Road bike but that lists for $4000. Hope that helps you suggest the best option for me. I welcome all input!
