AIRFLO Bike Pump

EXCELLENT Bike pump!Okay first off, these bad reviews are either user error or competing brands because I didn't have a single problem.I found this bike pump at Salvation Army for $3.75 and because of it's excellent build quality and portable size, I decided to buy it, even though I already have a couple bike pumps. When I googled this pump after my purchase I saw the negative reviews and I was worried. Whelp, I just inflated my first 26x2.2" tire from about 15psi to about 50psi according to my finger-matic squeeze test. When I removed the air chuck there was only a quick momentary hiss, perhaps 0.1psi overall drop and that was it. No dramatics, no tire deflation, just quick filling and quick disconnecting. How to use.Okay, this should be super intuitive on how to use, but for those wondering or having problems, this is for you. Random Tip: Add a tiny drop of lubricant on the valve threads to make it easier to screw and unscrew.Step 1 : Determine your valve size and use the correct side of the air chuck.Step 2 : Thread on the chuck from the reverse side. The silver knurled collar is connected and turning on one side, turns the other side. Note* Listen for the slight hiss of the valve opening, then turn maybe 1 more turn, don't overtighten but tighten just enough.If when pumping, air escapes, tighten a little more. Step 3 : Pump away. It took 100 pumps for me to go from around 15psi to around 50psi. Easy to useStep 4 : Disconnection - Turn the bottom knurled knob to remove from the valve. Pay attention to loosen and not tighten it. Support the air chuck with your other hand slightly so that you aren't putting binding pressure on the chuck, making it harder to unscrew. ( This is not pump specific, always do this with thread on air chucks. )And you're done. Product Upgrade Ideas.1.) Add better knurling on the knobs to thread on and off the air chuck, although a quick chuck would be way more appreciated.2.) Add some sort of air gauge so that people can see the psi. 3.) Have a air release button so that people can release air if they have overinflated the tire.4.) Have a hose securing bracket or have the hose screw into the bottom of the handle like Lezynes Digital Shock Drive pumps.I hope this helped some people. This is a good pump and I would recommend it.

The valve extension device leaks so much air when you remove it from the tire valve that the tire deflates. It's impossible to inflate the tires.

When you start to unscrew the connector, air starts leaking. It's impossible to unscrew it fast enough before the tire pressure becomes too low.

Got this since a few months now and cannot figure out how to attach it to the tire. We got a Woom 4.Pls help

The pump doesn’t have a pressure gauge. It’s useless if you’re trying to pump to the recommended pressure.

My boys and I have used tons of bike pumps in the past but this woom pump knocked our socks off! Like everything from woom the quality and design is spot on. Beautiful, lightweight, and high-quality. The pump works great and we love the presta/Schrader valve screw on attachment, it is very secure and my boys can easily attach and pump their tires on their own. We always throw it in our backpack to take on the trail. Highly recommend this Woom Airflo pump you won't be disappointed!
