Mini Bike Pump, High Pressure Schrader & Presta Valve Ultralight Accurate Inflation Compact Bicycle Pump for Road,Mountain and BMX Bikes

This is a nice lightweight emergency bike pump. I carry it and a spare tube in the seatbag on my beach cruiser. Because of its size, it takes a fair amount of effort to fill a wide cruiser tire, which is to be expected. But it works well as intended as a roadside pump. I recommend that any serious cyclist not leave home without it.

to small..but is ok

I'm an avid road cyclist, riding 4,000 to 5,000 miles a year. With that much time on the road, I inevitably get flats. Carrying multiple CO2 cartridges is awkward and heavy -- but one cartridge is often not enough. A larger frame pump is an option, but it's also a little heavy. This mini-pump will do the job and get you back on the road with little fuss. The key thing is to get all of the threaded connections quite tight so that there is no air leakage when pumping. Expect to compress the pump well over a hundred times to get a firm tire. That's a bit time-consuming, but it is not hard work. If you carry this mini-pump, plus one spare tube, and a patch kit, you will be ready for almost anything. It's a nice piece of kit.

I expected an aluminum casing for this pump. Its plastic; You get what you paid for. Enough punch to get you back on the road. But, it will come with a price. Especially if you're running fat tires. 😓

Just mounted it under my water bottle cage, love it! Tiny pump, came with all sorts of adapters, looks cool and actually works well. Pictured is my old emergency pump which was rubber banded in the same spot. The new one is smaller and uses a legitimate mounting system. I am more happy about this purchase than I care to admit!

Not super easy to use but it'll get you pedaling again.

Much smaller than I expected, which is awesome! Everything clips in quite nicely and build quality is really good. It takes a while to pump up a mountain bike tire, but it's so small that you can stash it anywhere

*will not* work on presta. I certainly wish i would have read all the reviews or tried tue connection before getting stranded 14 miles from home. This pump needs an adapter and i was able to order through amazon for a few dollars... but still, completely false product description. Also, when I put a new tube in place, 142 pumps got me to 40 pounds of pressure before air started escaping the pump. The small size still gives me a good rescue pump and not a perfect solution to get back to riding.
