Small low pressure pump?; I

[MinnBobber]

Looking for small, low pressure (0- 30 psi ) hand pump with accurate built in gauge .

Something to quickly and easily , check air pressure and adjust ….especially for changing snow conditions.
5” winter tires
3” summer tires

You didn't specify shrader or presta valves, though.

This is probably the pump to purchase, though it is heavy and expensive:

MICRO FLOOR DRIVE XL

The Micro Floor Drive XL is an advanced portable hand pump with floor pump capabilities developed to efficiently inflate high volume bike tires, e.g. mountain bike. It features CNC-machined aluminum construction, keeping weight to a minimum without sacrificing durability. 35 PSI max.

You can get it with either an analog or digital gauge on the filler hose. I know a lot of folks (and myself) swear by the Lezyne Micro Floor Drive pumps. They can move a lot of air quickly and are very reliable. The pump cup will dry out but you can easily disassemble the cup and use sunscreen or lip balm to get it to pump again.

You can find cheap chinese knock-offs of that pump online as well. Of course you have wildly varying quality on a piece of equipment you'll need to depend upon.

You do realize that even though 5 and 3" tires may run best at low psi that it is actually the volume of air in them that you are messing with? So I would suggest you change your search from a low pressure to as small of a HIGH VOLUME pump as you can find. The Wolf Tooth Encase 40cc is one option that I know of?

A small hand pump for a 5" tire? No thanks.

About 25 years ago I bought a Bell floor pump for maybe $15. I'd say it was made to function well and to last. The hassle was the lack of a gauge. I'd stand to pump, get down to check pressure, and stand back up to pump. I don't remember seeing a floor pump with a gauge what was likely to be accurate at 0 to 30 psi and be easy to read standing up.

With an e-bike, I wanted a little pump that could get me home in the event of a puncture. I bought this.

I would have preferred manual for reliability, but this one turned out alright. There's a segmented gauge to show how much is in the battery. If I unscrewed the valve core to let all the air out of a 3" bike tire, it would fill it to 30 in 7 minutes. After 45 minutes of doing this repeatedly, the electronic protection shut it off to cool, and the battery was mostly full. The pressure gauge is accurate.

I think the chuck is usually the trouble point for pumping bike tires with Schrader valves. On a car, you can shove the chuck on and yank it off to minimize air loss, but a bicycle wheel moves too easily. I ended up getting a ball chuck with a clip. I bought a 20" hose to screw into the pump so I could lay the pump down and use both hands to get the chuck on and off with negligible air loss. I bought a barbed adapter to match the chuck to the hose. Changing the hose and chuck took time and trouble, but it works so well that I no longer use my compressor tank for airing at home.

I adapted this pump's plug to fit both of my e bikes, always have a battery on the bikes, works very well, pump 4'+ fat tires very quickly.

I bring my shock pump with me when I ride so I can adjust my shocks, but it also works Great as a low pressure pump (20-60 psi)

It's got a long throw handle that pushes out a lot of air at low pressure and doesn't feel like you're trying to crack open a coconut when you pump it into the Red Zone.

My built in gauge sucks for accuracy at low pressure but I just verify with a different gauge, and I'm sure that there's a similar pump with a more accurate gauge.
(digital can suck when the battery dies)


I pumped up my 27.5" X 2.8" semi-fat tire from flat to ten psi in five minutes. That's good enough and fast enough for me.

What about a rechargeable pump?

My pump has been working for almost two years now,..
(@Nvreloader had the same one though and it crapped out on him.)

I've had a few issues with it but the batteries are still good.

It runs off 12V dc (three cells in series) so you can run it off your car battery if it croaks.
It's also a power bank with a USB output and a white or red flashing light.

Something to quickly and easily , check air pressure and adjust

You can preset the tire pressure that you want and simply connect the valve, read your current pressure, turn on the pump, and it will stop pumping when it gets to your preset pressure.


I found out that it's not good to charge it up then store it away for a year waiting for an emergency.
The batteries may be dead and won't take a charge, then the thing is garbage.
(Although I can plug mine into 12V dc to run the compressor pump)

(and don't let it bounce around too much as @Nvreloader suggests)


Using it regularly is the way to keep it alive and keep an eye on it.
You're not going to wear it out by using it, but you can kill it by not using it.
