I think I love this pump...

I'll believe it when you tell how well it works after you own it. It's still a little pump. Volume is proportional to length and the square of the diameter. Probably takes 3-4X more strokes than my floor pump, and mine can take 50-60 strokes for a fat tire at 20 psi.
 
I'm sorry, but I was looking at this pump as a replacement for a mini pump in the field, not a floor pump at home.

There is an XL version for fat tire bikes. The XL version is limited to 35 psi. When I read the reviews on Amazon for both pumps they are generally extremely positive, except for the built-in pressure gauge being not very usable. In terms of putting lots of air in a big tire quickly when you have a flat out in the wilds these pumps look awesome.

I just discovered this pump. It looks awesome for filling up a big tire and is only a little heavier and bulkier than a typical mini pump...

This is the "mini-pump" that I usually carry. I carry this inside a bag. The other mini I have fits better on my trunk bags that have external pump straps. So when using those bags I carry my other mini. But yes, this Lezyne as with most of their products is pretty good quality. I have their digital shock pump (really tiny) and it works so much better than the analog shock pump that came with my R&Ms. Also have their Micro C GPS watch. A bit rudimentary but gets the job done for me.
 
Thanks for pointing this out. I have bought 3 pumps that didn't work once from the local bike shop. The Schwinn foot pump from Meier's works, but weighs about 3 lb, is much bigger than this, and the glued on hose turns to dirt at about 15 months age. I used mine 3 times this weekend, had a tire crack that chewed up 3 tubes, but the schwinn is such a p**. Where I have flats, I'm miles from cell phone service on tracfone. Verizon cell works out there, for about $115 a month my friend tells me. Too rich for me.
 
I bought a lyzene pump. That one was out of stock when I was putting together an order so I bought the one with no floor flange and a rubber tube that screws in one end. The other end of the rubber tube screws on the schrader valve. It works, filling a 26"x2" tire in about 40 strokes. Before that no portable pump but the 5 pound Schwinn foot pump has worked. The LBS sold me two *****y frame hang pumps that wouldn't hold onto the valve for one stroke.
At home I use a slime floor pump that fills a 26"x2" tire in 6 strokes. I have an electric 12 v pump, but since I don't drive a car all the car batteries are sulfated & useless.
 
I saw that Lyzene pump at the bike shop the other day. Expensive, but very nice looking. If you are going to ride a bike, best to learn how to fix flats as they will happen sooner or later. I recommend a trial run at home. It is usually not necessary to remove the wheel to find and patch the puncture, but a dry run of wheel removal is also advised. I always carry a pump, fresh patches (the glue can dry out) and a spare tube when I ride.

If you know only one bike maintenance skill, fixing a flat in the field should be it. Followed by cleaning your chain, should your bike be so equipped.
 
I now have this pump and finds it works pretty well. While it certainly doesn't move as much air as a good floor pump it moves much more air than most mini pumps.

There are a couple of caveats:

  • Lezyne pumps have a design flaw with Presta valves where they can unscrew the valve core when you unscrew the pump from the valve. This means all the air you just pumped into the tube goes out and you need to start all over. This pump and later Lezyne pumps have an air bleed valve which apparently somewhat mitigates this design flaw.
  • The pump handle is a hard plastic with sharp-ish edges that can be kind of uncomfortable to pump. Not a problem if you wear bike gloves.

I use a Craftsman 19.2 volt cordless Inflator. I also use the batteries for my drills, sanders, etc. Works great and fills to 60psi in record time vs. a hand floor pump, Very portable and pretty lightweight. Can also top off auto tires with battery charge left to spare. Very efficient.
I always carry the Crank brothers CO2 Inflator in my saddle bag. Have not used it, however, I was told that it will do the job.

Here's my go to field pump...

At the end of a flat repair I just want to get riding again. A CO2 inflator does it for me. A single 16g cartridge will fill our mech bike tires to full pressure. It takes 1-1/2 cartridges for our ebike tires. Cartridges are ~$1 in a box of 20. I share with my sons, so it's not as many as it sounds! 😉
