think it's natural to enjoy going "fast" or "faster" cuz the very act of riding propels us faster than we could manage w our own two feet. so it's part of the attraction to the sport. was interesting watching my kids learn to ride. they started slow but soon wanted to go as fast as possible. still remember my daughter spinning like crazy on her trike trying to beat her older brother on his two wheeler. I've got a road bike which seems to be holding up. cpl yrs ago I picked up a cpl hybrids & have been enjoying unpaved but good quality rail trails. been thinking lately I might like to get drop bar bike that can take 45mm tires. gonna be a challenge finding such a critter, pre-owned, in my area. might have to settle for a cyclocross bike
