"The way it was meant to be"
Why on earth would anyone want to ride a fixed gear bicycle on the road? If you've never done it, this may take some time to answer. Riding with a fixed gear is a different experience compared to a multi-speed bike, and I'll try to describe some of the enjoyment that I get from doing it. The contrast is almost like a different sport.
Fixed is fun! In a way, it's like learning to ride a bike all over again as experience the subtle joys of discovering an efficient way to get from here to there with a lot less energy than walking or running. The simplicity of a fixed gear bike adds to the aesthetics of the machine and enhances our awareness of what a magnificent invention the bicycle really is.
It is a distinct surprise to realize that you don't always need a gazillion gears to ride a bike! A fixed gear continually reminds you what you are doing, and keeps you involved with the bike and the road. Climbing and descending your favorite hills becomes a new challenge, and the fixed gear adds a new dimension to your familiar terrain. Not to mention that it's a huge mental load lifted from your shoulders when you realize you don't have to worry about what gear you are in all the time. With a lightweight bike that is designed for the task, you will absolutely rediscover cycling.
"Bikes are fixed or broken."
--Dave Perry, Bike Works NYC
"I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a dérailleur? We are getting soft... As for me, give me a fixed gear!"
--Henri Desgrange, L'Equipe article of 1902
Enjoy, change is good.
