En fixed gear sykkel (fastnav) er en sykkel hvor drevet bak er skrudd fast på navet uten frihjulsnav. Så lenge hjulet går rundt går også kranken rundt og omvendt. En fixed gear sykkel kan også sykles baklengs...

Riding a fixed is a powerfully sensual experience...

The effect of the fixed gear is that the pedals are forced to revolve whenever the bicycle is in motion, as much by the momentum of bike and rider as by any force applied by the cyclist to the pedals. Instead of the bike seeming merely an inanimate tool which the cyclist puts to work, the fixed-gear bicycle asserts itself as something like a partner. The fixed gives you constant, rich feedback about your speed, the gradient, your cadence, the wind, the state of the road, the condition of your legs. It demands dialogue; it forces its point of view on your attention. To ride a fixed is to find yourself in a deeper relationship with a bike than anything you have hitherto realised. It is as if it has a mind of its own. You must treat it with respect and tact. If you do, then it will reward you with the smoothest, most comfortable, must subtly satisfying miles you will ever ride. If you choose a sensible gear, then you will roll as if there were always a gentle tailwind at your back. The miraculous sensation, transmitted through the cranks, that the bike ‘wants’ to keep moving forward, that it is willing to work with you, somehow plants the idea that this is a perpetual motion machine, devised just for you. This is not entirely fanciful. The chain drive is a highly efficient transmission. With a well-maintained chain, friction losses can be as low as 1.5%. Which, put another way, means that the efficiency ratio of ‘power in’ to ‘power out’ can be as high as 98%. (Compare this with a car gearbox, which typically operates at about 85%.) Even the best derailleur mech will cost another 4-5% in friction loses. There is sound sense, as well as sensuousness, built into the simplicity of the fixed gear.

But it is the subjective quality of the ride that fixed aficionados love above all. There is a meditative, Zen-like quality to riding a fixed. More than ever, you are intimately aware of your cadence, the relationship between leg speed and ground speed. And yet it is an awareness just below the surface of consciousness, at that higher level of semi-reflexive motor function that seems to apply to many repeated, rhythmic physical actions. Pedalling a fixed has a lulling, soothing effect, which liberates your frontal lobes; your thoughts can go wherever they please. Riding a fixed can be mind-expanding business. You reach the end of your journey and find that you have solved some problem or made a resolution on the way, but without conscious effort. The fixed-gear bicycle has, of course, remained the staple of track cycling, where it is guaranteed that everyone is travelling in the same direction and, generally, at similar speeds. No brakes is the rule at the velodrome because, counterintuitively, it is safer for no one to be able to stop suddenly
