I have two Trek full suspension mountain bikes. I have a rear rack that holds my bug out bag. I am waiting to get a set of front pannier bags for each bike. I was thinking about a bag for the handlebars to hold a sleeping bag. We have been talking about getting a trailer to go on the back of each bike to fit the kids in with a bag in each one as well. I am still checking on those though. I have borrowed a few and I like them but I need to really test one out and see if I can break it. I want to buy one first as I don't want to break someone elses. I ride my bike to and from work and everywhere we go, the wife takes the kids and I ride. Sometimes my son rides with me.
