Best Single Speed Freewheel- Reviews and Buying Guide w/FAQs

Freewheels are one of those magical components of your drivetrain that make bike riding a lot easier. Going up steep terrain will also require you to put a lot of pressure on your drivetrain. This is where freewheels come in, to help you spend less energy.

Single speed freewheels are designed to only turn in one direction. They lock up in the other direction so back pedalling isn’t facilitated like front pedalling is.

Freewheels make your wheels turn faster than your pedals so you have more control over your bike riding without spending too much energy.

Why Does Your Bike Need a Freewheel?

A freewheel helps you ride easier but that’s not the only thing it does. It also prevents accidents. Your bike needs a freewheel to keep you safe while riding.

When you’re riding down from a steep ground, your wheels will turn due to the bike’s inertia of motion, causing your pedals to move by themselves and hurtling you forward. There’s no need to break down why this could be risky, you could crash into something or get badly hurt.

Your freewheel prevents the wheels from moving backwards as the teeth on the inside get caught in between the socket and create a block. Bike freewheels don’t just make riding easier, they also ensure your road safety.

Which Fixie Freewheel Should You Choose?

There’s a variety of freewheels to choose from to make your bike riding more enjoyable. But you need to make your choice based on how long you can use it for and how easy it will be to maintain.

It’s better to look at some freewheels side by side, compare them and to choose the best one from them. Granted, this will take a really long time and a lot of inspection, but that’s where we come in. We’ve got a list of some of the best gears to help you choose.

Single Speed Freewheel – Buying Guide

While buying a freewheel, you’ll need to consider several aspects and then make the right choice. For example, if you’re on a tight budget and want a quick replacement, it is better to go with SENQI or Zukka freewheel. Matching your new purchase to all your drivetrain components is also important.

The Chain Size

All freewheels on our list are available in different sizes. If you’re using a larger freewheel with more teeth, you’ll need to use a longer chain.

Your chain needs to be changed each time you’re replacing your freewheel terwise, you’ll end up damaging your bike parts. If you’re using a freewheel with less teeth, then your chain needs to be shorter or else it will get caught between bike parts.

Drivetrain Compatibility

Your bike’s chain, chainring, freewheel/cassette, derailleur all together make up your drivetrain. You’ll need to ensure your chain is the right length for the freewheel and the derailleur used fits in with the freewheel. You’ll also need to make sure your selected gears all maintain the ideal gear ratio.

Usually on the chainring there are 44 teeth in front and 18 teeth at the back. The ideal gear ratio is 44:18. This also indicates how much energy needs to be applied for your bike to easily move forward. The higher the gear ratio is, the faster will be your riding speed.


Sometimes freewheels are difficult to remove once they’re installed onto your bike. The cost for changing freewheels again and again is also quite high. So you’ll need to select a freewheel that’ll last long and not get damaged easily, even through your rough riding.

Shimano’s single speed bike gear and CyclingDeal’s single speed sprocket will be the right gears for you in this case. They’ll last long, will be easy to replace when they wear out and will be compatible with other Shimano components.


Since changing your freewheel requires you to change your chain as well, you may need to change your chainring too as incompatible chainrings and chains will damage all your bike components.

But all of these replacements might just cost you an arm and a leg if you’re on a tight budget. If you’re looking for freewheels that are within a reasonable rate, you can try Shimano’s single speed freewheel or Zukka’s single speed freewheel. SENQI single speed freewheels also guarantee quality within a reasonable price range.


Bike parts need to be constantly maintained and repaired to keep them working in top notch condition. But you also need to replace the parts whenever they wear out, to avoid damage to other parts too.

Whether you’re picking out a new derailleur or replacing a chainring, or choosing a new chain, you’ll need to match up all your equipment compatibility and check if they work best for you and your bike. But don’t forget to clean and grease your bike and all its parts regularly for optimal performance and the best riding experience.
