AviatorTroy, why your experiment went to a fail?
This one looks interesting and price is right... I'm tempted to try...

I stripped down a $10 pump from walmart, looked very similar to the one above, it lasted about one good inflation, then just pumped so little air I tossed it in the trash.

maybe it was a cheapy, or maybe I burnt it up, but it became apparent that I could not rely on it, so i went another route, heavier and larger, but works everytime.

It would have worked OK but I tried to cut back as much of the casing as practical to reduce bulk, and there are some exposed gears and such in there that just don't do well without the case. It's hard to explain, but the case takes up about 3 times as much volume as the mechanism inside. That Aerostich item looks just like what I tried to do, leave the case around the delicate bits but leave the motor and robust parts protected.

I think it could work, and if I remember right, the HF item was about 10$ but I couldn't find it on their website anymore.

This was the one.

But like I say now I have the Slime one which packs up really small, but is painfully slow.


I also have a Blackburn 2 stage bicycle pump that I use for emergency backup.

The small pumps don't have a 100% duty cycle, and you can only run them for about 15 minutes before you have to 'rest' them for about 40 minutes.

The current small pumps use too much plastic. They melt

Here is another thread talking about portable air compressors and the search engine yields more. Would be nice if there was a way to combine these threads:

that makes them about worthless in my opinion.

this is what I carry with me now, been using it for a couple of years, lots of tires on trailers, trucks, cars, bike,s bicycles..

they are even on sale right now, I paid $24 for mine.

Time and milage tried.

Carried over 50,000 miles filled many bike tires usually not mine.

Never an issue. duty time is just fine.

small pkg rides in top lid of side bag.

Well spent cash

A BestRest Cycle Pump lives in my top case. It was a gift so I can't complain about the price. www.bestrestproducts.com

It's actually faster than you would think. I would say it's almost as fast as a cheap electric compressor, like the slime one posted. For the math people it's 50 CM3 per stroke, and it pumps air on both the in and out strokes. I just bought it a week or so ago so I can't comment on longevity, but I aired up a front dirt bike tire from 0 to 15 psi pretty quickly testing it.

Why is everyone so against the hand pump? Never overheats, never has a dead battery.

I changed the tire on my girlfriend's KLR yesterday, just for the heck of it aired it up with my hand pump. 6 minutes from a new collapsed tube to 30 PSI on the rear tire. Used the real compresser for the front.

Just wondering really, but I can't see a reason to carry my electric one anymore.


Edit- here's a quote for the $100 Cycle Pump refrenced above. Note that it took me 6 minutes with my hand pump:

Tire inflation time varies by tire size, air density, voltage, laden or unladen tire load, and other factors, but as a practical rule the CyclePump will fill a front tire in 2-3 minutes and a rear tire in 3-5 minutes. Topping off a few extra pounds takes less than a minute. Just how powerful is it? Don't worry, it'll fill your tires quickly and it's rated to pressures over 100 PSI

Jules083,

Just curious, what "handpump" you used? One that most people have in their garage for their kids bikes (stands up, with feet, two-handed pump action) or a tiny fits on a bicycle pump like this one posted earlier http://www.blackburndesign.com/pumps...l#.UP9qzB3Ac-c ???

If one of these mini manual pumps can do it in 6 minutes vs. various heavier, bulkier, costlier motorized pumps 3-5, it may be worth it --- unless of course you're at 13,000' elevation with thin air, in the Rockies at 28 degrees, huffin' and puffin' and giving yourself a headache... That won't be bothering me here in Jerzee, but I might not want to rely on it for my planned month-long primarily off-road trek to CO and UT.

[jules083]

Coorbust-

Mine is the same as the one you listed, only made out of plastic and $10 instead of $30. 6 minutes for a rear 17" klr tire going to 30psi. Saves weight, packing room, and less chance of failure imo.

I'll put some pictures up when I get home.

All typos and misspellings blamed on my phone.

[jules083]

I was at wal-mart where I got my pump here it is in it's original package:



Look under the crossbar pad and you'll see it. I was thinking of mounting the bracket here but I changed my mind:

[strsout]

So, who here really inflate a empty tire with a hand pump?
how long takes?
and I'm talking about GS tires, not those tiny cross bikes tires...
