So currently we have 2 cars, although one of them is borrowed from family, and they want it back. Usually on Thursdays my wife drops our son off at pre-school, and then I leave my job, pick him up, switch to the bike and ride it back. I looked at the mileage, and while it adds 17 miles in the middle of the day, it's all relatively flat and I can't think of a reason why I couldn't ride to work, ride to pre-school where my wife would have left the trailer, and then ride home. My question is I have both a road bike and a mt. bike, and I have towed the trailer plenty of times with the mt bike, but I have never towed it with the roadie. Its a Raliegh Grand Sport, aluminum frame and while its not exactly the top of the line, I do like it and don't want to jack it up. Can I tow with it? The ride from school to home is about 6 miles all flat except the final mile which is up a pretty good hill. Or should I suffer with the mt bike, making the commute seem longer if it isn't really.
