This is the smallest, lightest compressor we carry and one of the most efficient you’ll find for its size. This stripped-down mini fits in the palm of your hand and will inflate any motorcycle tire in a couple minutes. When a larger compressor is too much bulk to carry along, and CO2 cartridges aren’t nearly enough for your trip, this dedicated pump will deliver continuous pressure without fail. What it lacks in beauty, it makes up for in performance – which is what you really need when you’re flat stranded in the middle of nowhere.
Has a nice long 26" inflator hose, 6' power cord, and packs small in included storage sack. Comes with three adaptors: SAE, cigarette lighter and alligator clips. Lock-down delivery valve fits all bikes. Also comes with carabiner clip, so you can attach the compressor to whatever you want out of the way and off the ground, instead of having it lay in the mud or dirt. Simple, compact, and dependable peace of mind. Pump is 3.5"×3.5"×.9". Packs to 7"×5"×3", 1.3 lb.

- Used once, worked greatReview by Errol
I never had an issue with this pump. The switch worked fine for me once I realized it rotated in one direction. I haven't had to use this for an emergency, but my friend and I checked our tire pressures in Fort St. John on our way from Reno, NV to Whitehorse, YT and it worked perfectly to get us both back up to a proper pressure.
I have one recommendation for the next revision of this product. Place a Schrader valve on the end of the outlet, just after it tees off to the pump hose. This way you can maintain the compact size while giving an easy way to attach a tire gauge to check pressure without having to constantly remove pump from the wheel. (Posted on 7/14/15)
- No goReview by Echo15
- Bought this several years ago for that "hope I never need it" situation. Well, finally had that situation and.....nothing. No power. No compression. Borrowed a bicycle hand pump to get home. (Posted on 4/8/15)
- Small & Fast w/some flawsReview by Monty
- This is one of the smallest and fastest pumps on the market (and cheapest) but as many have said in reviews, the switch is defective and the wires to the motor can become disconnected quite easily. I returned my first pump and received another with exactly the same problem with the switch. You have to bend the wires around the switch to get the pump to energize. I have decided that it will cost me the same to buy a more robust switch at Lowe's than to return the pump via UPS. There was another fellow who recommended that you dip some of the motor connections in vinyl coat to protect the connections from shorting out on the frame (sparks) and to use some locktite on other screws which could back themselves out. I will do all of these things as well. Most of the folks on my last ride liked the size and efficiency (quick air-up's) of this pump than the bigger, more expensive ones they were carrying.

- Great Things in small packagesReview by HookedonHarley
- I was a little dubious of this compressor after reading all the reviews talking of switches, open wires, and stuff breaking. But I could not find anything comparable, so decided to give it a try. I am pleasantly surprised. Yep, it has a few weak points, but it comes with a very usable storage bag, and, with a little care, this compressor works very nicely. If you are concerned about the switch and wire issues, they can be easily remedied, and I believe the compressor itself is worth the investment. (Posted on 7/16/14)
- Size does matterReview by Mark
- Small package in this case is a good thing. Has the power to fill, packs down small. The in-line cord switch is a little hinkey - takes a few times to get it to close the circuit. (Posted on 7/8/14)
- Better than expectedReview by Cathleen
- Gave it to my husband for his birthday. He has used it twice and is surprised at how fast it will pump up a flat tire. From zero to forty-seven pounds in just a few minutes. He doesn't like the exposed wires though. He fears they will be vulnerable to breakage floating around in a saddlebag. (Posted on 4/30/14)
- not a good choiceReview by Darren
- I thought this would be nice because it is the smallest of the options and less expensive. The tab that locks the nozzle to the valve stem broke completely off the very first time I used it. Now I am out of country and finding this bit is impossible. Go with the Cycle Pump. I have had one for years ant it still works. (Posted on 4/28/14)
- It WorksReview by Trundlebike
- Lost my first one to a thief, had to have another. Functional, durable, and has a great mechanical presence. Put loctite on all the screws and replace the switch if you must, but this device is a keeper. (Posted on 4/11/14)
- Works but with problemsReview by Jerry
- As others have stated the switch is terrible. I have had mine about 5 years. First time I used it (for practice) it went OK except extra practice getting the hose to clamp on deep enough to let air in. Next time the switch did not work. I had to take it apart and reconnect it. A couple of more times all OK just had to be careful seating the hose clamp and taking it off. The last time It aired up the tire but not to full pressure but the plastic gear cover came off, screws fell out. I am shopping for a better one. (Posted on 4/5/14)
- Replace the SwitchReview by Dean
- As it has been said numerous times; the switch is junk. Save yourself a potential crappy day and replace it right off. I've used mine a couple of times to repair tubeless flats and it works pretty well. (Posted on 3/12/14)
- Mini with an MReview by Dave
- Stores perfect under the tail section compartment of my R1200RT. Fabricated a couple of additional wire harnesses to work with the BMW power outlet and clips direct off a battery. Always remove the pump after washing the bike or a trip and test a couple time a year. (Posted on 12/2/13)
- It's The Switch.....Review by Mike
- The pump is powerful, fast, connects to the SAE plug on my Tiger, and is relatively compact, however like Franken Beemer and Woody, I found the switch to be...well, horrible. Last week I was all alone ten miles north of Mann Lake OR (the least populated area in the lower 48). I needed to "air up" after riding 42 miles of gravel, and the switch would only work if I pulled on the wires with one hand. Try airing a tire with one hand sometime. Astonishingly, my friend Bill from Maine experienced the same thing with the same model pump the foillowing day. A great pump and motor, but install a better switch when transiting the "Empty Places". (Posted on 9/12/13)
- Compact PumpReview by John
- After looking at several 12 VDC moto air pumps I decided to buy the Stitch version, mainly because of the easy to attach valve fitting, and better reliability reviews. All of the reviews pointed out the obvious deficiencies in this product, and as a former electronics technician I can relate to a couple of them. NUMBER 1. The electrical connections to the pump motor are bare and uninsulated. That is just sloppy design, and it would be easy for them to correct with a couple of layers of shrink tubing. I'll do that immediately. NUMBER 2. The motor and gear assembly are exposed, which leads me to believe this pump is adapted from something else. The plastic backbone (frame) seems to have obviously been designed to attach to something else; likely the other half of the motor/gear cover. NUMBER 3. The switch is a cheezy rotary lamp switch, which will likely need to be replaced with something a bit more rugged. It wouldn't take a lot of effort for Stitch to complete this design by just adding a motor/gear cover to the existing backbone (frame), then putting a rugged switch on that cover. Those few changes would create something that would look and operate like a professional product. Right now it looks like something someone knocked up in their garage. The other products out there either had a lot of reliability issues, which you don't want on some back road with a flat; or the valve connector was difficult to use, or unreliable. The pump works well but these other issues indicate a lack of professional design. (Posted on 7/19/13)
- Perfect for R1150GSReview by Manuel
- I have installed the cables to this little pump to the battery and fed then under the saddle to a good point to zip tie it for eazy access. Also bonus the pump with it's nice cover bag fit perfectly in the space that is left betwen the battery lower back side of gas tank and saddle on my 2004 R1150GS Adv. Just had to use it for the first time last week. After plugging the tyre pumping it up was slow.. maybe 10-15 min.. I did give it a rest in fear I may overheat the pump.. but all in all solid, compact and well gets the job done! And I am very happy with my purchase.. (Posted on 7/9/13)
- Aerostich Mini CompressorReview by MICHAEL
- purchased the mini compressor just in case I would need it; never thinking I really would. Well, went on an Arkansas bike trip with family on 3 bikes. One of the riders noticed a nail in my tire the first day. Plugged it and used the compressor to add air. It worked great. In just a minute or so, I had added 5-6 lbs. of pressure. Then, later in the trip, my brother-in-laws front tire was low. Used the Aerostich mini compressor and once again it worked very well. The compressor is also fairly small and doesn't take up much space. It hooked up easily to my 12 volt connector and it comes with 2 other ways to connect to the battery. If you are considering purchasing a compressor for you motorcycle, I highly recommend this one. (Posted on 7/9/13)
- mini compressor we will use for other tires too.Review by Phillip
- Don't know yet how good this as it is a gift to my son. We think it is extremely cool, minimalist in design, and says everything about your company and it's philosophy. Will let you know how it works when i can get it away from him! (Posted on 6/4/13)
- Aerostich Mini CompressorReview by D in AZ
- Recommended by dual sport friends.Terrific little machine and reliable. Inflates tires quickly. Fits nicely in my tank or tail bag. (Posted on 5/22/13)
- Good pump but needs some protection...Review by DRTBYK
I've had a number of small pumps over the years and most of them work OK but each one of them has it flaws. This pump has been durable (although I did disassemble and locktite all screws) and I do like the cam-lock on the Schrader connector. Much better design than the thread-clip that most of these little guys have.
The one thing I do think needs some attention is the solder terminals on the motor. These are exposed and can easily short out on the bike frame, etc. I just carefully dipped mine in some Vinyl Coat, making sure not to get any in the motor. No more sparks! (Posted on 4/24/13)
- Aerostich Mini compressorReview by Kenneth
Item arrived quickly and well packaged.
Powered up and appears to run properly. Have not tested on tire inflation yet. Beemer is tucked away for the Michigan winter. Will test in the spring when bringing air pressure up to spec's. (Posted on 1/10/13)
- the switch!Review by franken beemer
- I read reviews......decide to get the pump but resolve to use the hell out of it before taking it on the road. Sure nuff the switch acts up while filling up wife's car tire. The little booger won't keep working unless it's twisted in the right angle ,then it starts smoking! So after taking it apart I realize there is nothing too complicated here, just reset the cord in it's place out and retighten! Now it's working and will continue to be abused until the snow cover recedes....and the riding season begins! (Posted on 1/7/13)
A Flat Tire Story
When introduced (long ago), Aerostich tire pumps and tire repair kits set new standards for efficiency, compactness and functionality. Thousands of riders have come to rely on this equipment -- both in the workshop and out on the road. Both pump and kit have been subject to continuous refinement and improvement. Now, the tire pumps 'on-off' switch has just been redesigned. Literally a small detail. Now a different type so this tool is even more reliable.
Have you ever needed to repair a tire on the side of the road? Here's a story from 2009 about one such experience:
Last summer I had two in-motion rear tire flats on my (street) bike...both only about a week apart. They were my first on-the-road flats in many years. Both were due to riding on dry-rotted inner tubes. My maintenance forgetfulness and ignorance. My bad.
Luckily no crash resulted. Somewhere over the years of changing tires I'd forgotten the lesson that one should always put a brand new tube in when installing a tire. I replace a worn out rear tire on this bike about twice a year. What could I have been thinking?…save money? Modern tubes don't rot? Uhhh…
Riding southbound on US 53, just north of Wascott. This road is now a fully four lane divided type, with a 65 mph speed limit, and that’s the speed I was going. Sunny and nice. Light traffic. About 2 PM. The bike started to steer funny. It was subtle -- as if I was riding on a worn-out road with depressions where heavy traffic had thinned the pavement. But the highway looked perfectly flat so I moved over to the center of the lane to check if it actually was the road. A flat tire was the very last thing on my mind.
Hmmm. Bike still wiggly. I looked again at the road surface just a few feet ahead. Hard and closely. Still looks flat. So I slowed down to about forty five and it seemed to go away. Then I sped back up and the wiggles came right back. Like the frame, swingarm or a wheel had somehow broken. It had been a really long time since my last flat. More than ten years...I'd completely forgotten what having one felt like.
And then I knew and slowed back down to about 30 and started riding along the paved foot-wide shoulder. In about two blocks there was, as if made to order, a little gravel side road. I took it and ten feet in stopped and looked down. The rear tire was nearly flat. I slowly and carefully rode another five feet to a good spot to park on the side. And now the tire was fully flat.
The next stuff was routine…but it had been a very long time since I'd done any of it: Bike off. Off bike. Hoist onto center stand, which was hard because the bike was now 4" lower in the back. Gloves off. Helmet off. Jacket off. A nice pile on the grass next to the bike. Saddle off. Tools out. Wheel off. Spare inner tube out. Tire irons out. Tire off rim on one side. Tube out. No apparent flaws. No nails in tire. Just a giant tear maybe a foot long. 30 minutes elapsed, but I'm not hurrying. Just keeping track…
Spare tube in. Tire back on rim. Dig clearance hole in sandy dirt beneath where the tire will go and slide wheel onto hub. Bolt on loosely. Get out engine inflator - a hose that goes from one spark plug hole to the tire. You start the engine, which runs fine on one cylinder and in a minute the tire is full.
Except the attachment that goes into the spark plug hole is ruined. Twelve years rattling around in the bag on the rear fender have removed it's threads. There is no way that will work. Plan 'B'...a bicycle tire pump strapped to the frame. It doesn't work either. I fiddle with it for fifteen minutes but the rubber 'o' ring seal that goes on the tire valve stem was all dried out and would not make a seal.
Back to the thing that works off the spark plug hole. I wrap duct tape on the worn-threadless end and put the other end loosely onto the tube - threading it only a single turn. Put on the riding gloves. Feel like Mr. Spock working in the starship Enterprise's reactor radiation chamber, taking a big chance to save the ship. Start the bike. Chuff! Chuff! Chuff! air blasts strongly out the spark plug hole. I'd forgotten.
The bike runs great on one cylinder. With my left gloved hand I force the duct-tape-improvised-gasketed device against the spark plug hole holding it there as hard as I can against the air blast while with my right hand I'm screwing the other end onto the tire valve stem. It works. 34 psi and two tries later I have done what felt like the impossible. Boy that little chuff-chuff inflator gets sure hot quick. Even with a glove, it was hot-potato-drop-it as soon as I unscrewed the other end on the valve stem. Bolt the wheel back up tight. Put away the bad tube and the tools and I'm off, gingerly at first. An hour and twenty, total.
Midway through all this, a Subaru Forester passed, heading into the forest. It was the only vehicle on this road the whole time. Twenty or thirty feet away I could see and hear the endless stream of Hwy 53 traffic whooshing past. The Subaru went about forty feet past me and then I heard the gear whine of it reversing, so I stopped levering and looked up.
An old thinnish, long-bearded man was driving, and when they were back next to me his wife was looking down, out of her just-lowered passenger window. I was on my knees by the tire, looking up at her. "Need any help?" the old country hippie guy asked. "No, I think I'll be ok." I replied. Steady eye-to-eye contact. Pause. Then we smiled at each other, and nodded very slightly. A moment of reflection both ways, then they drove off to their presumably reclusive homestead hidden place somewhere farther into the deep Wisconsin north woods. Just a few miles out of Wascott. My guess is he plays a fiddle.
I continued on to my destination, and enjoyed a nice dinner with some friends. Afterward, when I got home at about 9 pm I took all the tools out and removed the wheel, deflated and re-inflated the tube, and made sure the just-replaced tube was inside the tire straight. Then got out a brand-new spare tube and left it on the saddle, ready for it's place inside the bag on the back fender.
Tomorrow I'd replace the 'plan B' bicycle pump, the thread less Enginair 'chuff' thing, and probably the tube repair glue and patches, too. The torn and dried-out old tube went into the garbage. I bet it had been taken out, inspected and put back ten or twelve times when I'd change tires over the years. Never had changed that tube. Never thought of it. What a dummy…
Postscript, four days later --
The lesson was that twelve year old inner tubes are neither reliable or safe. They wear out just like the tires do, even if they don’t show anything visually like a tire does. The above tire repair happened on Sunday. The following Thursday I’m riding down Interstate 35, heading to Minneapolis at five pm, and about five miles north of Hinckley the back tires goes flat again. And again I ride along for a minute in denial or disbelief, this time thinking “I can’t be having a flat again -- I just had one.”
This time there’s no nice quiet gravel side road available, just a sorta steeply sloping mowed shoulder, and freeway traffic here is pretty intense. I am traveling with another rider, and again I do get the bike pulled over safely. But I cannot easily put the suddenly lower (flat-tired) bike on it’s side stand, so while I’m holding the bike I direct the friend down into the ditch to see if the ground is wet or dry or hard or soft. He finds a semi-dry, semi-firmer place about five feet from a semi-wetter semi squishier place and I roll the bike diagonally down the steeply sloping grassy ditch, stopping right by were the mowing ends and the tall grass begins. At least I’m not right on the shoulder…inches from the continuous traffic roaring past at eighty.
This time the change goes much faster. Probably about fifteen minutes, start to finish, without hurrying. Minutes before leaving I’d re-packed the fresh inner tube, the replacement ‘chuff chuff’ device (with it’s fresh spark plug threads carefully wrapped in tape to protect them) and a new bicycle tire pump. I’d picked up these supplies on Tuesday and Wednesday and an hour and a half earlier had rushed to pack them. The new ‘chuff chuff’ thing worked fantastically well. I’d forgotten. What a breeze.
The other rider was impressed. And so was another couple who had stopped a few moments later to see if I needed help. They were on a newer BMW, heading for home, which was Texas. Working away I was smiling -- it was as if I was giving a lesson on how to quickly change a flat tire on the side of the road. As if I knew what I was doing. Sunday's practice had re-taught me all the right moves.
As I pulled the still warm four-days-earlier-replaced ‘spare’ tube out of the tire it literally came apart in my hands. I could tear it in almost any direction, as easily as if it was a sheet of newspaper. During the years it had been inside of the little bag strapped on the back fender it had completely dry-rotted, even more than the one which failed the previous Sunday. Another big ‘duh’. What a dope. From now on, I’ll know better. I’ll become an inner-tube-fanatic, changing to new tubes whenever I change tires. Change your tube with your tire!
This whole experience got me thinking about the knowledge-base that underlies the entire tire/tube changing skill set. It’s a near-obsolete collection of information about task sequencing, manual manipulation and material science. It’s as if I am the operator of a steam locomotive or some other archaic mobility technology.
These days mobility involves very little of this kind of knowledge. Vehicles don’t come with tools or inner tubes. Many tires are now ‘run flat’ so there’s even no spare. Most newer motorcycle use cast wheels, and tubeless tires. Inner tubes are needed only for traditional low-end spoked wheels, since ‘tubeless’ would leak where the spokes pierce the rim.
When tubeless motorcycle tires go flat it’s usually due to a nail in the tread. The standard roadside remedy doesn’t involve removing the wheel. A pliers is used to pull out the nail. Then a reaming tool is used to clean out the hole, and another reaming tool is used to jam an adhesive-coated plug into the hole. Then the insertion tool is removed and the plug’s protruding length is cut flush with the tread. Then a small electric air compressor is connected to the battery and the tire is reinflated. Much less fiddling around.
This Mini Compressor surprised us. I was afraid that after a few years of bouncing around inside a saddle bag or pack this might not work when needed. I was wrong. (After once experiencing a flat in a fairly remote place I found both long-carried innertube-filling pumps -- an old Enginair hose kit and a 'backup' bicycle tire pump -- had failed. Those simple tools had both been damaged by me not packing them away carefully enough.) In contrast the little Mini Compressor has been working for our customers when its been most needed. Who knew that it would turn out to be so reliable?
