LEZYNESport Drive High Pressure Bicycle Hand Pump | 120psi, Presta and Schrader Compatible, Mountain & Road Bike Pump

I’m happy with my purchase of this little pump. It was very easy to use and I had a great experience with it so I’m satisfied. Plus the price was pretty good. I put it on the bike and it’s really nice and small. I had a pop tube in a tight spot with very little space between the road and swamp area and the first time using it and I was very pleased. It worked like a charm.

Most cyclists like me, have always defaulted to Co2 for flats because pumps are often either huge, or small and essentially useless for any manner of practical use. This pump is very close to the Holy Grail of on bike pumps: it's tiny and it can handle pumping tires over 100 PSI, without leaving you exhausted. This pump is a winner. Here are my thoughts in more depth:1. It's obscenely small. As you can see in my photos, it's barely the length of a bottle cage when mounted to a bike. In fact, if you really want to avoid cluttering up your bike for fashion purposes, this will easily fit in the middle pocket of any jersey.2. The flexible screw on hose does make pumping easier.3. There is absolutely no need for a bleeder valve, just simply slowly loosen the part of the hose screwed into the pump until the additional air comes out, then unscrew the hose from your inner tube valve.4. Yes, expect to engage the pump 150 or so times to get your tire to 110-120 PSI, but only the last 15 or so pumps are going to be at all difficult. What I do is pump in 25 pump increments. Either way, this is what you're looking at for various tires, sizes and PSI:Continental GP 400023mm/100 PSI= 153 pumps23mm/110 PSI= 183 pumps23mm/120 PSI= 213 pumps and a somewhat tired forearm25mm/100 PSI/110PSI/120PSI= add approximately 10-12 pumps per above numberI also ran this on a Vittoria Pro G Plus in 25mm, Vittoria Corsa Control G Plus in 25mm, and Zipp Tangente Speed in 23mm with very similar results to the above numbers.With that said, in the vast majority of cases, riders rarely need to run their tires at max PSI. Unless you are 230+, you can easily get away with between 95-105 up front and 105-115 out back. In fact, anyone under 230 really should always run their front tires at no more than 100 PSI and back at no more than 115, anyway, and that's especially the case if you're running 25mm or even more so, 28mm. The typical exception to that tends to be nearly anything sold by Vredestein, which tend to have weak sidewalls and recommended max pressures of 145-175, which is absurd, but that's a story for another time.I'm rambling here, but here's the bottom line:This pump is tiny and capable pumping road tires up to spec to safely continue rides, not just as a pump to limp home with. Yes, you're going to spend a bit more time getting tires to pressure than a Co2 pump, but you're also not going to waste as much money. Oh and 2 cartridges and an inflation device is going to run around 130-140 grams, this pump is 105 grams; I rest my case.

This is a good emergency pump.Pros:1) Small and lightweight2) Solidly made, quality is good3) Flexible tube connector4) Bike mount for pump works good. Just make sure the pump is positioned correctly in the mount.Cons:1) Since it is so small, the length of each pump is limited so it takes a long time to fill up a high pressure road bike tire, and it is hard to get it up to the pressure you would want in a road bike tire. That is kind of a given for these small pumps, though.I use this as an emergency pump to put a little air in the tube so I can get it mounted in the wheel. I carry a CO2, which will fill the tire up to the road bike tire pressure. It can be used by itself, but it will take many, many pumps to get enough pressure in the tire, and that will take considerable effort.Overall, it works for me and the small size and weight are worth it.

If I need to patch a tube on the trail, this will yield enough air pressure to get me back to base. I can accomplish about 20 pounds with it with about 100 strokes.

The pump functions by threading a hose onto the pump, then threading the other end onto the valve. This is a very reliable connection that allows the pump to move without risking damage to the valve. To me, this is the best setup for a minipump. All the threads on the pump were very well machined and easy to use, as long as you are careful during set up.

Absolutely fantastic mini pump. One of the most obvious advantages of this pump is the flexible hose that comes with it. One of the biggest drawbacks of most mini pumps is that they don't have hoses like full size pumps, and therefore have a tendency to damage the valve on your inner tube. The excellent hose on this pump overcomes that.At around 7.5 inches in overall length, this won't fit in most saddle bags. Fortunately, the pump comes with an excellent holder that mounts on the bottle holder screw holes. It actually sandwiches between the bottle holder and the bike frame, so you can attach both the pump and the bottle holder onto the same pair of holes.Although it seems small, it took only a minute of pumping to get a completely uninflated 26x1.95 MTB tube to around 30psi, which was more than sufficent to ride on. All of the connections are sealed with O-Rings, which don't exhibit any signs of falling off in the future.The only thing I have against this pump is that the female threads on the main body of the pump (onto which the hose screws) are plastic, and not metal. They seem durable and don't appear to be prone to stripping, but I would have preferred the extra peace of mind.

It's very small, it's very light and it isn't noticeable weight-wise in my Osprey Raptor 10 pack when riding. Haven't needed it myself (yet) but helped another rider who got a flat. The way it stores with the hose is a nice design. I don't really care that there's no pressure gauge or anything. If the tire feels firm once inflated it's enough to get back to the car.

Mindre än jag trodde. Känns som bra kvalitet.Fäste medföljer, inklusive kardborrsrem.Blir en utmärkt nöd-pump.

Ottimo prodotto ,a un prezzo scontato.

Dit verouderd systeem met het slangetje werkt nog altijd veel beter dan due met een vaste kop

Appears very effective although I have not had a reason to use it yet, I am confident that it will do the job.

Parfait tres compact!
