I watched this a few times and appreciate your clear, concise comparison. I did see however that while connecting your pressure gauge after using the CO2 cartridge, the tire noticeably deflated and sank down a bit. I don’t know how much pressure was lost, but it was clearly enough to observe and possibly change the pressure readout. I recently bought a couple of fat bikes and also a CO2 kit for them. What I now believe is that 2-3 cartridges will provide enough pressure to ride to an air hose to finish the job. I’d hate to be putting 500+ strokes into that small inflation amount a compact pump provides. Keep up the good work!
The problem with the cannister is sometimes you have to pump up to find the leak, then make the repair, then fill again. A nice high volume mini pump is probably the lightest way to go out
Older video I know, but I thought it might be worth mentioning: the CO2 will be cold when it is rapidly discharged meaning your pressure will be a bit lower. As it heats up your pressure will increase. In terms of a bike tire I'm not really sure what that would look like, but something to keep in mind. If you fill the tire right to the max pressure you may find it exceeds that after a little bit of riding.
i used a 20g on my 4.6" tire just now in a 64 degree basement... i got the psi up to 8-10psi... checked it an hour later and the pressure was about the same...
@@scotthamilton1054 ok that's good to know, although something to keep in mind is that CO2 will slowly defuse through rubber. I think it takes about a week to see a noticable change, unlike regular air it will slowly leak out. It's definitely a good choice for seating a tire, or if you get a flat while on a ride, but it definitely isn't a permanent fix. You will have to fill it up with a regular pump. Not sure if that was mentioned in this video or not though since I watched it about 3 months ago
What he didn't mention is that Co2 will only last for about 24hrs because Co2 is thinner and will leak from the tire. A pump will have multiple uses in any condition.
24hrs gets you back home or to a shop with a proper floor drive/compressor, right? I'm all about not spending 30-45min on the side of the road in 10° weather
I'm not sure about the maths. You got 4.5 pounds of pressure, is that 4.5 psi? My tyers take between 50 to 80 psi. Does that mean 5000 pumps of the hand pump at a minimum?
im able to get 8 psi from a 20g cartridge on my 4.6' wide fatTire.. i can take the rest of the way with a hand pump if needed. or take 3 20g canisters with me.. i ride high pressure (20psi) on hard packed crusher run...
Could drop a 20-Ounce Tippmann Co2 tank in your pack or stretch out a drink holder on your bike to fit the tank. Would need a few adapter pieces, a twist or lever valve and the hose end parts from an old tire pump to complete the setup but I'm sure it would work far better. A bit larger than of one of those AZ .99 green teas.
A good informative video'.. thanks.. I have a Co2 version...The instructions within the box.. state that.. Co2 cannot remain in the tyre... upon returning home.. you need to replace it with 'air' from a pump.. which defeats the purpose of the 'quick cylinder' method... sure, you get one fast inflate while out..... but it doesn't keep.
@@FatbikeRepublicNL Gotcha'.. yes .. Co2 is not a suitable medium for inflating tyre tubes.. so I continue to use a trusty old air pump...with good old trusty 'air' .... thanks for comment.. Cheers from the UK.
Doesn't defeat in any way: You got your tire inflated immediately with two carts, I keep 4 with me should I get a double-flat or someone else in need, and then a few minutes worth of hand pumping rather than 30min. Done. The purpose is to be back rolling for that trip ASAP, especially in cold weather. Purpose acheived. Deflate and fill when you get back home
They're a lot alrger and heavier though, 400 grams for the Xiaomi one for instance ! They're slow too...but to get 7 PSI on a road bike you'll need that over a hand pump or a CO2 cartridge will do nicely as well ;-)
The video doesn’t say what size is the Co2 cartridge. They come w/ 16, 20, & 25 grams. The PSIs obtained from one cartridge depends on the sizes of both the tube, and the cartridge.
That particular one is a 16g. a larger cartridge or multiple cartridges in this case would make more sense. I just ordered that CO2 inflator for my road tires which should be more than enough. Those little pumps are tough to get to 100 psi.
First off what size cartridge are you using? The pro bike tool CO2 inflator that you are using with the cover for the cartridge will only hold a 16 g CO2 cartridge. But being a threaded on styling inflator, meaning the CO2 cartridges are also threaded I think you could use a 24 g cartridge without the cartridge cover. Larger tire larger cartridge.
Correct, I was not using the larger cartridge. The smaller one fit inside the unit. Larger cartridge = more volume and would give different results. Thanks :-)
I thought 💭 of it many 👨 years ago, when I and my stepmother were sitting in a restaurant, talking about one ☝️ of these mini bike pumps. I told her that it’s possible to inflate a Caterpillar grader tire with one. Yes, it can be done, but it would probably take from sunrise 🌅 to sunset 🌆, getting the tire up to 80 PSI, which grader tires take, although this can vary by the manufacturer 👨. It happened to be some story I came up with, because we were probably bored 😐, and didn’t know what else to talk about. Again, a mini bike pump can inflate a grader tire, but you’d need an adapter for the larger diameter tire valve of the grader rim. This could also possibly wear the mini bike pump out, because this would be an extreme number of strokes of the pump. Your friend, Jeff.
They're really not, just shop online. Shops/US bike brands gouge extremely hard on such absolutely simple and cheap by slapping their name on and charging a 2000% markeup.
I guess im screwed because i run 18-20 psi constantly on my fattie lol electronic is the only option to go, a bit more expensive & heavier in comparison is the downside - upside i can also go tubeless and hopefully not get a flat with that
im able to get 8 psi from a 20g cartridge on my 4.6' wide fatTire.. i can take the rest of the way with a hand pump if needed. or take 3 20g canisters with me
pump...always the pump. why? because there is nothing as disappointing as using your last co2 cartridge, and finding 2 more leaks from those blackberry vines you ran over.
A 16oz CO2 cartridge will fill the volume of a skinny tire inner tube to 100psi but the volume of a 4" wide mountain bike tire is enormous in comparison.
I agree. and it's just for emergencies but pumping for 500, 0r maybe much more, could make you pretty tired and you still have to ride to get home. For my bike, I look for the biggest pump I can fit somewhere on my bike
It's quick, easy, and light. It's especially important when you are out in the mountain all by yourself after sunset. You can reduce waste by using less soda cans.

Tire sank because he pressed into it, not because of air leaking.
More escaped (which is normal with this tools) when measuring pumped tire pressure.

Great video. Thank you.
---------------------------------------
500 strokes @ 4.5 psi = 500/4.5 = 111.11 strokes/1.0 psi
1 canister CO2 @ 1.5 psi = 111.11 x 1.5 = (equivalent of) 166 strokes

Yeah, think he meant bars and not PSI

4:21, 1.5 PSI? That doesnt look like 1.5 psi when the tire filled up so nicely.
It does kinda look full, but there was no weight on the bike.
It's 1,5 bars.
This was an ideal opportunity to see how many cartridges would be needed to fully inflate the tube.
It would take a few. :-)

It doesn’t defeat the purpose, because at home you have a track pump 🙄
i did not know this!! this explains a lot!! jeeze.... 35 years inot cycling and im still learning something new

I have very light ipump 23 gram hand pump! Oretty awesome device.
Battery powered air compressor is a better choice nowadays.

Do you have some experience, what one cartridge can do to a flat 4'' tire?
Hmmm . . . I would say a 20 or 25. I never tried it though.
There are lots of type of mini pump, some really practical
Tell me what you think about the pump in a rain or snowstorm?

co2 are expensive for us normal riders, I prefer hand pump
co2 is for emergency only. Once back home you should empty the CO2 and refill with air. Why; CO2 diffuses 11 times faster through the rubber than air.
They're really not, just shop online. Shops/US bike brands gouge extremely hard on such absolutely simple and cheap by slapping their name on and charging a 2000% markeup.

Nice video
What size CO2 cannister did you use?
Co2 for a 16 inch Brompton?
pump...always the pump. why? because there is nothing as disappointing as using your last co2 cartridge, and finding 2 more leaks from those blackberry vines you ran over.
Lol. Funny and true.
Or carry 3 or 4 carts? Idk, my emergency kit does at least but I always ride with a bag
1.5 PSI? On my road bike i used 100 PSI.. .. What do i missing? Or do you mean 1.5Bar?
Nope. 1.5 psi. Super low pressure.
@@FatbikeRepublicNL its like nothing inside the tire if only 1.5 psi
@@SepuluhSeptember Pretty much this side of nothing.
1.5 Bar makes more Sense^^ For this kind of bike you need a minimum of 2 co2 container. 16g is super for Roadbikes.
A 16oz CO2 cartridge will fill the volume of a skinny tire inner tube to 100psi but the volume of a 4" wide mountain bike tire is enormous in comparison.
Interesting. I'm doing some research as I'm about to a similar pro/con video. 1.5psi only! Wow!
Ffs depends in the grams of the cartridge. He doesn’t explain that. If you get a 25 g cartridge you’d fill both front and back tyres.
Get a higher volume MTB pump instead of a little road pump.
no
4 inch stroke?? That's pretty average right? Id say that's average.
Nice
I would suggest a bigger pump
Its hard to balance volume and pump size for the trail.
I agree. and it's just for emergencies but pumping for 500, 0r maybe much more, could make you pretty tired and you still have to ride to get home. For my bike, I look for the biggest pump I can fit somewhere on my bike
don't you mean 1.5 bar not psi
co2 carts make alot of waste just to fill one tire!
If looking for speed inflation, there is nothing quicker. However, there is the cartridge to dispose of.
Metal is still recyclable.
It's quick, easy, and light. It's especially important when you are out in the mountain all by yourself after sunset. You can reduce waste by using less soda cans.
Both need a gauge...
Most gauges in pumps and co2 inflators are pretty trash. You should just have a dedicated gauge.
