I have a Burley Piccolo. I've been using an old MTB on city tires to pull it. It's worked great, but it is 15 years old and needs about $300 in parts to bring it up to spec. So, I'm going to get something new. I have an old, but very serviceable road bike to use when I want to get out by myself and cover some ground. This bike would be used for towing the trailercycle, going to the store, goofing around the neighborhood with the kids, and for rides where I don't feel like riding a drop bar bike.
So what are y'all using to pull your trailercycles? Any particular recommendations, like wheel and tire size? The roads here are smooth, but it's hilly, so I need some low gears but don't need suspension. Obviously, I want something stable. I've been thinking about either a Trek 7.3 FX or an SU200, a Cannondale Road Warrior 400, and a Specialized Globe or Globe Sport.
