With a name like Travel Trac you’d think this bike accessory would be good on the go, but actually it is ideal for going nowhere when on a bike. The Travel Trac Book Caddy, which is available from Performance Bikes, is actually a handlebar system that can hold a tablet PC or a magazine. But what about those of us who read an actual hardcover book? We’re not sure if the Travel Trac has us covered, but it sure beats balancing a book on a the handlebars!
