Single Speed vs Fixed Gear Bikes Explained For New Riders. Some riders like to joke that single speeds actually have three gears: sitting, standing and walking.
The main difference between single speed and fixed gear bikes
The main difference between single speed and fixed gear bikes is how the drivetrain behaves when you stop pedaling. A single speed has one gear but uses a freewheel, so the rear wheel can keep rolling while your pedals stay still, giving you the option to coast. A fixed gear has the rear cog bolted directly to the hub, so the pedals always move with the wheel, meaning no coasting and full control of speed through your legs. This makes single speeds better for relaxed riding and fixed gears better for those who want a direct, always-engaged feel.
TLDR: Single speed and fixed gear bikes remove shifting, which makes them lighter, simpler and more reliable, with a slightly more efficient and peaceful riding experience. The trade off is that you cannot adjust for climbs or descents, you must plan your momentum carefully and you may need to experiment to find the right gear ratio. Geared bikes remain the most versatile choice, but single speed and fixed gear bikes can make familiar routes feel new and provide a rewarding back to basics challenge.
It is a lighthearted way of pointing out that when you strip a bike down to a single ratio, you also remove the safety net of shifting. This leads to the question many new riders ask. If multi speed drivetrains made bikes more versatile and easier to ride, why do single speed and fixed gear bikes still have so much appeal today. The short answer is that removing gears can bring benefits in reliability, weight, efficiency and even the overall experience of riding.
Of course those benefits come with real trade offs. So let’s go through exactly what you gain and what you give up when you choose a single speed or a fixed gear bike.
The Main Drawback of Single Speed and Fixed Gear Bikes
There is only one major drawback and it is right in the name. You cannot shift. If you need more torque on a climb you simply grind it out or get off and walk.
If you want more speed on a descent you pedal until your legs cannot turn any faster and then you coast on a single speed or you spin out on a fixed gear. A geared bike will eventually run out of low and high gears too, but not nearly as often.
A less obvious drawback is figuring out what gear ratio fits your terrain and riding style. Most riders spend time and a bit of money experimenting with different chainrings and cogs until they find a balance that works. This is even more noticeable off road where steepness changes much more often.
Fixed gear bikes add another layer. Because you cannot coast, you need to be even more aware of your momentum. There is no fallback option. You must anticipate slow sections and build speed before you reach them. It will make you a more efficient rider, but it also takes time to adjust to thinking that far ahead on every ride.
The Practical Challenges
There is also the simple matter of availability. Entry level single speeds and fixed gear bikes are easy to find, but if you want something more specialized or higher end, it is rarely available off the rack. Most experienced riders end up converting a frame or building from scratch, which is rewarding but not convenient.
Why Riders Still Choose Single Speed or Fixed Gear
Now that the drawbacks are out of the way, it is worth looking at why people still choose these bikes. Reliability is by far the strongest practical reason.
Without shifters, cables and derailleurs there is less to service and less that can go wrong on the road or in harsh weather. In mud and snow this can make a dramatic difference.
Cost and weight savings are additional bonuses. A basic derailleur drivetrain weighs over a pound more than a simple freewheel and chain. An internally geared hub weighs even more. When you remove all of that, the bike gets lighter and cheaper to maintain. Some bike shops even charge less for tune ups because there is simply less to adjust.
Efficiency is another small but real advantage. Every pulley or moving part adds friction. Because single speeds and fixed gears remove those parts, they transfer power a little more efficiently. Any identical gear ratio on a single speed usually feels slightly easier than the same ratio on a multi speed bike.
There is also the simple visual appeal. Without cables and derailleurs the bike looks clean and minimal. Most riders do not choose a bike only for aesthetics, but the tidy simplicity does add a sense of satisfaction and pride of ownership.
The Psychological Side of Riding One Gear
For many riders the biggest benefit is more subjective. A single speed or fixed gear makes familiar roads and routes feel new again. You introduce challenge not by traveling farther or buying more advanced equipment, but by doing more with less. It is a different kind of novelty that is more sustainable over time.
Another advantage is the peacefulness that comes with not thinking about shifting. Even experienced cyclists keep track of gears subconsciously. When the option simply does not exist the ride becomes a little more quiet and clear. That can be part of why people ride in the first place.
So Which Should You Choose
A geared bike is the best default choice for almost everyone. It will let you ride more places with less effort. That is exactly why gears were invented. But if your rides are mostly flat, or your weather brings heavy mud and snow, or you want familiar terrain to feel fresh again, a single speed or fixed gear can be far more enjoyable than you might expect. It becomes a back to basics challenge that is rewarding precisely because it is not as easy.
Choose a geared bike for versatility. Choose a single speed or fixed gear if you want simplicity, reliability and a different experience on rides you already know well.
