Electric Air Pump Portable Air Mattress Pump Quick-Fill 110V AC/12V DC Inflator Deflator with 3 Nozzles for Inflatables Air Bed Boat Raft Mattress Outdoor, Car Use, Indoor, Black

This is fine, solid pump that packs a lot of power in a tiny package. I've filled the tires on my beach cruiser and road bikes (around 20 to 90 psi) with a minimal effort. If you want precision, you'll need a separate gauge, though. The stowaway compartment for the needle and presta adapter is a little tricky to open--don't do this over the lawn the first time or you'll be on all fours searching in the grass for the pieces.It comes with a neat little holder with a rubber clamp, designed to fit the tapped holes on your frame for a water bottle holder, if you have them. My bikes don't, but it should be a simple enough job to jury rig an adapter. Or, stow it--it's small enough to fit in a pack or even a pocket without noticing.Road Air also sends a pdf booklet "Cycling For Life" with your purchase, which is a nice touch.

Overall a good pump. A good balance between solidly built and lightweight. It certainly works. Like all mini pumps you need a lot of strokes, but I was able to inflate my tires to 85 psi easily enough. It is native Schrader and you need to use the (included) Presta adapter. I would have preferred it the other way or convertible. You need to remove the adapter each time in order to put the rubber seal back on. And the rubber seal itself is not tight enough and falls off the end of the pump. The aluminum tube body of the pump that you hold while pumping is fairly short (2.75") and has a sharp, unfinished edge that forms a painful pinch point with the piston. The mount doesn't hold the pump closed while riding. But it fits in my saddle bag nicely - solving most of the problems. I am totally happy with it.

I've been with Amazon since 2003 and this may be my best/favorite purchase yet. I'm a wheelchair-bound paraplegic, who's self-sufficient (for the most part). I've been airing and changing my own tires from the beginning. For 14 years, I've been using the old style bicycle pump that I had to lift my legs and put my feet on its pedals to hold it in place. It had a clip on valve which, if you didn't get it on just right, you could pump a thousand times and get nowhere. Even when the valve was put on correctly, it required a lot of pumping, and the pumping got more difficult as the tire filled. THEN, as you were struggling to take the clip valve off, you hear this HISSING, and you lose a third of the air you just put in.The Best Mini Bike Pump is named appropriately. It weighs less than a Big Mac, takes up no room, has an extendable hose that stores within itself, and tools for airing balls, inflatable toys and different valves store hidden on the other end.As far as performance goes... NO HOLDING IT IN PLACE!!! Easily attaches to the tire valve by screwing on securely until airtight. And the BEST part was that the tire was tight and road ready in about 4 EASY pumps (The tire was low, not empty).If I had one complaint, it would be that the mounting attachment is made for bicycles with water bottle holders. If they had created the mount's bottom identical to the top part that holds the pump itself, I could clip it right onto my wheelchair (and remove it) with ease. Still, I think I can rig it with black zip ties and it will be perfect.BUY IT!!!!

I actually paid for this, unlike most of the other reviewers. I've been mountain biking for 25 years, so I'm well versed in these pumps.There are basically two types of these things: ones without a little hose that pops out and ones with the hose. The hose makes pumping these WAY easier, because it separates the pump (which you move around as you pump it) from the valve, but the hose adds weight and saves a lot of wear on the valve and the better the hose, the heavier it is. The hose in any pump also is likely to be the first thing to fail.I had a plastic pump with no hose and the thing weighed only 3 ounces, this one weighs 5.5 without the bracket, and 5.4 if you remove the two adapters for filling balls and other inflatables that you probably will never use. Most of the extra weight comes from what appears to be a very high quality (and therefor heavy) hose.I was really prepared not to like this one because of the extra weight, but the two extra ounces are probably worth it, especially if you are going to make this your only pump. The reason is it's a lot of extra weight to carry around if you are only going to use it in an emergency. With tire liners, I only seem to get a flat every two or three years, and about half of those are slow leaks that can be fixed at home using the floor pump. So carrying around the extra two ounces for something I'll only use once every five years is probably overkill. It's also twice the price of the plastic pumps and the plastic one I had lasted 15 years. The likelihood any company will be around in 15 years to honor a warranty is low, and you could just buy a second half priced one and that gets you 30 years.I deflated a presta valve tire and it reinflated it relatively quickly, though the amount of air per pump is lower than others that are engineered to maximize that issue. Note that it takes a couple of pumps to put enough pressure in the thing to push against the presta valve to open it, so you have to pump a few times at a fairly rapid clip or it won't add any air at all. The design will also limit the amount of air you can pump into a presta valve tube. 70-80psi is probably about the best you are going to do, though I didn't test it.So this was a tough call on how to rate it. Where it excels is a situation where you are going to beat the heck out of the pump, like keeping it in a backpack because the all plastic ones don't hold up too well in that situation. So for a commuter like me, it works and I'm keeping it. It's also a good choice if you aren't going to have a floor pump because of the hose. However, if you want something to take on the trail that you'll mount to your bike and then remove, and you have a regular pump like a floor pump, you can save a few ounces and get a plastic one that maximizes the amount of air per pump.So I started with 5 stars for being well built. I took off one star for the small amount of air per pump and extra weight. I took off one star for the price being twice as high as others, and rate this one 3 stars. Based on the price, I think I wished I had spent more time and bought something else that was lighter and cheaper, even if I had to replace it in 15 years on my own.
