I suppose I should be grateful that my bike is only about 64 lbs.–a hybrid bike, plus various accessories, plus panniers, plus whatever is in the panniers at the time. However, knowing that Strava thinks that no bicycle is more than 50 lbs. at least makes me feel a bit better about the fact that my average mph is only about 8. In my defense, many of my rides are up and down Wisconsin Avenue, and that two-mile uphill out of Georgetown definitely lowers my average speed!
