Hi, I would like to start commuting to work on a unpaved rail trail. It is 50 miles round trip and I have to carry about 40 lbs of gear for my job. The questions I have are: Should I use panniers, backpack, bob trailer? I have a kid trailer. Could I use that? Are the panniers easy to put on and remove? I will still be using the same bike for singletrack a few times a week so I don't want to spend a lot of time on bike set up. Maybe I need another bike? I just bought another bike 3 months ago so I don't know that my wife would like that plan.
