CO2 Bike Tire Inflator Pump Kit – Portable Emergency Mini Inflator with 16g Cartridge, Trigger Control, Presta & Schrader Compatible for Road, MTB & E-Bikes – 3-Second Inflation (See Video)

Really cool pump, used it to seat my tubeless 29" mtb tires, as I dont have a strong enough regular pump to do that. This is also the only one I've seen that allows you to use the non threaded c02 cartridges, which is nice because those are cheaper and easier to find.

The EZI Bike Pump works great, saved me a number of times a long way from home with a flat tire.I did have a slight problem with the bracket, I e mailed EZI Bike and Steve from EZI Bike responded quickly and solved my problem beyond my expectations. I'm a life time customer.Jay

looks good, but haven't used it yet. I have another just like it and it works fine.

Don't buy this item, because I have tried to use this pump to pump up my tubeless tires but it doesn't work due to its low air pressure comes out even you use CO2 cartridge. And they don't have the return policy that's sucks

I replaced my 12g inflator with this similar item that accommodates only 16g CO2 cartridges. Maybe it's me, but after inflating a 700x28 tire, there is no CO@ remaining in the cartridge. BUT one 16g cartridge puts PLENTY of gas in the tire, but not two tires. You should carry two CO2 cartridges with you in case you have a bad day with more than one flat tire.

Amazing how well designed and well made this CO2 pump. A quick and easy way to inflate a tire. Only complaint is that the mounting bracket is a bit confusing. Finally mounted it where a rear rack attaches on an upper chain stay. Other than that, great item.

My favorite feature of this pump is the way the air cylinder is stored inside the handle without even puncturing the nozzle. You just put it in backward, and that way they stay together until needed. And of course the way the handle completely insulates the user's hand while using to avoid that terrible "freeze" I got from my simpler pump, where I had to end up wrapping the cylinder in a towel to be comfortable during use. This pump is very simple to use, safe, and is easily worth the extra ten bucks initial cost for something so crucial to saving the day with an emergency re-inflation of a flat tire to get you back on your way! Highly recommended!

Used inflator only ones, in a race it failed numerous times to the point the valve came off the latex tube. Moment of reflection. Happens. So decided to have this and its helpful in those situations , i have the compact unit as well.
