If you’re looking for an inflator that will fill your inner bike tube within seconds on the go, then a CO2 inflator is just what you need. Getting one for your bike saves you time and effort, and lets you get back to riding your bike as fast as possible.
CO2 inflators were initially just a favorite among mountain bike owners, particularly those who took part in races, but that has changed and today, these CO2 inflators are common among many who ride their bikes on roads and trails.
These inflators are made up of different parts, including a small metal canister filled with the CO2 gas and which is attached to a nozzle with a quick-release trigger to facilitate faster delivery of the gas at high pressure. The gas then leaves the canister at high speed, allowing your bike tire to get filled up faster.
A CO2 inflator is easy to use and requires little effort since all you need to do is pull the trigger once. Compared to a pump, it weighs less, and unlike the pumps, CO2 inflators don’t require any battery or mechanically operated mechanism to work properly.
They require low initial investment and all you need to do is purchase a valve with two CO2 cartridges. Buying a CO2 inflator is a good idea, but which one should you go for?
Here’s a review of some of the best CO2 bike tire inflators to help you make a decision.

Top 5 Best CO2 Bike Tire Inflators – Our Reviews:
1. Lezyne CO2 Inflator
The Lezyne CO2 inflator is great because it’s compatible with both Presta and Schrader valves. Weighing just 16g, it’s one of the best super lightweight inflators out there.
Presta and Schrader valves are two of the most valve types, so being able to carry this inflator around is ideal. Since it’s quite compact, the Lezyne CO2 inflator will fit with ease in your bike saddle bag without adding too much weight to it.
Its machined aluminum and black fiber give it a great appearance. The inflator’s nozzle is also available in a variety of colors such as black, red, purple, blue, and silver, and has a high-gloss finish you can choose if you’re the stylish type.
It’s fairly priced for a good-looking CO2 inflator.
The Lezyne CO2 inflator also features a control drive that allows you to easily control the gas flow. As such, you’ll be able to easily fill up any Presta or Schrader tube.
All you need to do is push the control drive onto the valve then turn the inflator head to release the air. You’ll have a good grip thanks to the knurled ring and you don’t have to worry too much about which way to turn it since there’s a little graphic found at the end of the head that’ll tell you this.

Its canister features an insulated sleeve that helps maintain its temperature, thus keeping the CO2 gas inside stable. The inflator nozzle’s one-turn valve system lets it open and close faster when releasing gas, compared to a rotation system which would actually take a lot of time.

The Pro Bike Tool CO2 Inflator is very lightweight and facilitates easy handling. It’s easy to use as it effectively delivers CO2 and inflates your tire within just a few seconds.

Birzman’s Roar Control bike inflator is one of those tire inflators that offer a neat touch compared to a number of other models you can find around you. You can easily control this inflator by twisting its CO2 cartridge.
You need to screw the threaded cartridge first on to the head so that you manage to puncture the seal. After doing so, slowly unscrew it to allow for the gas to flow.
If you’re wondering about the flow rate, it depends on just how far you unscrew it.
You can always allow the CO2 to trickle out until you’re certain that everything sits right before proceeding to blast your tire up to high pressure.
The Birzman Roar Control comes with a neoprene sleeve that slides over its cartridge so that you don’t suffer any freeze burns when you pump your tire. It also features a head CNC-machined from strong aluminum alloy to ensure durability and precision.
Plus, it comes threaded to facilitate screwing onto a Presta valve or a Schrader one.
Lastly, it’s one of the best CO2 inflating tools that allow you to pump without inserting too much effort because it’s lightweight and has a turn pierce function that controls accurate inflation when you pump your tire.
- Threaded CO2 cartridges
- Each CO2 cartridge is 3 x 16g
- Neoprene sleeve
- CNC-machined head
- Will easily pump your tire
- Prevents freeze burns
- Gives accurate inflation when you pump your tire

- Doesn’t work well for valveless inflation
As you can see from the review, it’s important to be careful when picking an inflator that you’ll use for a long time to pump your tires, whether they’re threaded or not.
To get the best CO2 inflator, always carefully check the material it’s made of. It could be either plastic or aluminum.
Aluminum is a great option, but you might want to go for the plastic version if you’re on a tight budget.
Keenly check the size of the inflator and the cartridge too. Ensure there’s a good balance between the tire inflator stability and its size.
Avoid going for a small type of inflator as it might not be the easiest to use.
Also, as mentioned already, the CO2 cartridge of your tire inflator can be a non-threaded cartridge or threaded.
The threaded ones are cheaper making them more popular than the non-threaded ones. The non-threaded ones are easy to use but there is the extra cost factor to consider.
Having reviewed these five best bike inflators, you may be asking yourself which among them is best. Well, my pick is the Lezyne CO2 inflator.
Aside from being easy to use and compatible with the most common types of valves available, it’s light and compact—perfect for carrying around as it doesn’t add too much weight to your bag.
Everyone loves a good-looking item and the glossy finish that comes with the Lezyne CO2 inflator makes it stand out among the best CO2 inflators that can pump your tire. Plus, you need not worry about the grip or how to turn it, thanks to the knurled ring and graphic indication that shows you the right direction to turn.
