Generally speaking, I'm never in a hurry. There are a lot of long hills here. I average 10 mph
on a laden tour bike, maybe 13 or 14 on a road bike,(with a tail wind). My somewhat
modified mountain bike averages 18 mph....but then i stuck a 2 hp motor on it. I don't often
ride it, but it's my hedge when I get past 70.(not too far off)
