I posted a thread last month that I was considering doing a short (week-long) tour with my 7-year old son. It's not a very long ride, but he's incredibly excited, and it's going to happen. The week has been selected, the time is requested off work, and I have 4 months to get things ready.
Fitness-wise, I'll resume bike commuting 11 miles each way to work daily when the weather gets better, and will be taking him out on many evening and weekend rides, including an overnight camping trip locally as a test run.
Here's the situation: I have a 1995 Mongoose Switchback mountain bike. This is a bike shop bike, before Mongoose became a wal-mart brand, so it's better than it sounds. I have a lot of miles on it, and it's been well maintained. I also have a Trail-A-Bike that he'll be riding behind me, and we've done hundreds of miles on it in the couple of years we've had it. (I've also done hundreds of miles with his little brother on it). Here's a list of things I'm expecting to do to the bike (much of it will make it useful as a wet-weather commuter too)
Trekking bar + bar tape
Fenders (and fender for trail-a-bike)
Front rack (already has rear rack)
Rear rack on Trail-A-Bike
I've already purchased Ortleib front rollers and back rollers for our stuff. The bike has fairly road-worthy tires (if I were buying tires today, I'd probably get big apples, but I have specialized armadillo all-condition tires, the center tread is smooth and they ride well enough). I'll have the bike rechecked for mechanical readiness shortly before the tour. I also have front and rear lights.
Anyone else who's toured, tell me what I'm missing in terms of bicycle accessories that you would expect to make the journey better, safer, more fun?
