Hycline Mini Bike Pump with Gauge: 140 PSI Portable Bicycle Frame Pump for Road BMX MTB Tires - Aluminum Alloy Fork Pump for Presta Schrader Dunlop Valves

Smart design, pumps quickly. I like that the tube is metal and hope this will last a long time

The Good:-Mostly metal construction-Lightweight-Includes frame mount-Includes adaptors-Hose (this is great, using the ground makes it much easier than others)The OK:-Manual gauge (not very precise but does the job for an emergency pump)-Little long for many bike bags (fine in a backpack or on the frame)-Lower airflow per pump (just what you get with small pumps)The Bad:-NothingThis is a tool many cyclists should have; it can save you some money on air canisters and easily works around multiple flats. The built-in tube is great for getting a better pumping position and you’ll definitely want that with these small pumps, it’s not a fast process to fill a tire. The built-in gauge is not very precise and only gives you an approximation of where you’re at but that’s really all you need. Have no issues filling tubes with tube sealant and it’s nice to have the flexibility to use both common valve types without an adaptor. Would have liked a wider handle or better design but again it does the job. Find the pump is just slightly too long for many seat and handlebar bags. Overall, if the price is right this is a better than average frame pump and will probably never let you down.

Well-constructed 11.5" tall air pump that can be mounted on a bicycle frame. It operates smoothly and is priced reasonably at $17.99 with a 10% off coupon at the time of this review. The pump is designed with a neat fold-out kickstand to step on for stability. Its gauge is accurate enough from about 40 to 60 psi. That’s where my bicycle tires usually stay. It does take a lot of pumping to inflate a bicycle tire. The barrel is only about 1" in diameter.One caveat: I could not get the plastic cone tip to screw in straight to the hose tip when it’s configured for Schrader valves. Once the main hose tip is unscrewed open and in Presta mode, I was able to screw in the plastic cone tip. They should have made the base of the plastic cone tip into a hexagon, or given it ridges. It’s smooth, so it’s hard to get a grip on with bare fingers. Had to get a rag to grip it.Second caveat: there is an inconsistency in the listing that says this bike pump goes up to 140 PSI, while the instructions on the back of the box say maximum pressure is 100 PSI. I cannot test maximum pressure as I don’t have anything to inflate that has a maximum rating of 60 PSI.The only thing I could really test is the Schrader valve tip. The pump works well with Schrader valves on regular bikes. I wish my large floor pump had the kind of screw-on Schrader tip that this pump has.

I got this pump as an addition to my mini-pump, which is much more compact, but takes forever to pump up my tire with just enough pressure when changing out flats. This pump has a screw on head, which might seem inconvenient, but the heads with the lever sometimes might loosen up when it is constantly moved around unless you hand is holding it in place the whole time. This unit is compact in size, so it will take a long time to pump up the tire. But with this design, you are pushing against the floor, as opposed to using the strength of both arms to push against each other, so your arms will less likely tire out before finish pumping. I was able to pump my 700x23 tire to 100 psi, with each stroke adding roughly 0.5 psi (starting roughly around 60 psi, which is when I started counting). The pressure readout seems to be pretty accurate, compared to my dedicated pressure gauge.The bracket allows you to mount the pump using the standard water bottle mount eyelets, alongside an existing water bottle cage, so you won't have to go thirsty if you opt to mount the pump. It has one thin rubber strap holding the pump, but I haven't had these things break on me yet. Once the pump is clipped on, it is a bit clunky, so I will likely relegate this pump to my backpack anytime I am wearing one.I haven't had to use it in real life situation or assessed it durability by having it repeatedly exposed to the elements, which I do with my year-round riding. But so far, it is a good upgrade from a compact hand pump, trading off a manageably bigger in size for much more usability.

The handle is so close to the tube I bang my knuckles on it when I press the plunger down. The gauge is difficult to see, though it does seem accurate. The worst thing, though, is the bracket holds the pump to the side so my leg hits it when I pedal. I gave it two stars for the cool schrader-presta conversion that doesn't require detaching small parts to reverse. I may move that to my next pump.

Like the title says. The pump itself is a nice little pump. It had no issues filling up my bike tires. I like the flexible tube and the screw-on mechanism that secures it. It makes it super easy to get in between the spokes.The gauge, however, is completely useless. It doesn't work at all and just seems to be constantly stuck at 20 PSI.I've tried multiple times, going over everything I'm doing, making sure it's not user error. I cannot find anything I'm doing wrong. The gauge I got just seems to be a dud.

I have a handful of bike pumps of a variety of sizes and have to say this one is pretty ideal for something to carry with you on the bike. I have some that are smaller, but it takes a million pumps to fill up a + tire, which sucks. This has a pretty good stroke volume, so I didn't feel like it took forever to do the job. Obviously a floor pump is faster, but I'm not taking that on the trail. The screw-on nature of it is nice as well, I prefer it to the flip-top types.
