Freewheel vs. Fixed Gear: What’s the Difference?
When it comes to bicycles, there are two main types of drivetrains that can greatly affect the way you ride: freewheel and fixed gear. These two options offer distinct advantages and disadvantages, so it’s essential to understand the differences before making a purchasing decision.
Freewheel
A freewheel is a mechanism that allows the rear wheel of a bicycle to spin independently from the pedals and the drivetrain. This means that when you stop pedaling, the rear wheel will continue to move freely. Freewheels are commonly found on bicycles with multiple gears and are controlled by a set of gears and derailleurs.
With a freewheel, you have the ability to coast, which means you can stop pedaling and let the bicycle roll without having to constantly pedal. This can be beneficial for longer rides or when going downhill, as it allows you to take a break and save some energy.
Freewheels also provide the option to change gears, allowing you to adjust the resistance and find the most comfortable setting for your riding style and terrain. This flexibility makes freewheel bicycles versatile and suitable for various types of riding.
Fixed Gear
A fixed gear bicycle, also known as a fixie, does not have a freewheel mechanism. Instead, the rear cog is directly connected to the rear wheel, so whenever the rear wheel is moving, the pedals are also moving. This means that if the bicycle is in motion, you must be pedaling.
Fixed gear bicycles offer a more direct and connected riding experience. They are popular among track racers and urban cyclists who enjoy the simplicity and control they provide. With a fixed gear bicycle, you have complete control over your speed and can quickly slow down or speed up by adjusting your pedaling.
However, riding a fixed gear bicycle requires constant pedaling, which can be tiring and less efficient for longer rides or hilly terrains. It’s also important to note that fixies do not have the ability to coast, so you must always be prepared to pedal.
To summarize, the main difference between a freewheel and fixed gear bicycle is the ability to coast and the requirement for constant pedaling. Freewheel bicycles provide the option to coast and change gears, making them suitable for various riding styles and terrains. On the other hand, fixed gear bicycles offer a more direct and connected riding experience but require constant pedaling and lack the ability to coast. The choice between the two ultimately depends on your personal preferences and riding style.
How Does a Bicycle Freewheel Work?
A freewheel is an essential component of a bicycle that allows the rider to coast, meaning they can stop pedaling while the bicycle continues to move forward. The freewheel is located on the rear wheel and consists of a set of gears and a ratchet mechanism.
When the rider pedals the bike, the chain engages with the freewheel, causing the rear wheel to rotate. This rotation is what propels the bicycle forward. However, when the rider stops pedaling, the freewheel allows the rear wheel to spin independently of the pedals and chain.
The ratchet mechanism inside the freewheel is responsible for this functionality. It consists of a set of pawls that are spring-loaded and engage with a series of teeth on the freewheel body. When the rider pedals forward, the force of the chain on the pawls causes them to engage with the teeth, allowing power to transfer from the pedals to the rear wheel.
When the rider stops pedaling, the pawls disengage from the teeth, allowing the rear wheel to spin freely. This is what enables coasting and allows the rider to take a break from pedaling without losing momentum.
In addition to allowing for coasting, the freewheel also plays a role in the bike’s braking system. When the rider applies the brakes, the freewheel engages with the hub, preventing the wheel from rotating. This stops the bike by creating friction between the brake pads and the rims of the tires.
