Brilliant pump and doesn't take up much space in a carry bag

The compatibility with both Presta and Schrader valves is a game-changer—it switches seamlessly without the need for adapters, which means no more fumbling around trying to fit the pump to different valve types. The connection is secure and leak-free, making inflation quick and hassle-free.The high-pressure capability is impressive. It handles up to 160 PSI with ease, making it ideal for road bikes, mountain bikes, and even BMX bikes. The built-in pressure gauge is accurate and easy to read, so I can inflate my tyres to the exact pressure needed, saving time and ensuring a smooth ride.At just 7.8 inches long and weighing 4.2 ounces, this pump is incredibly lightweight and portable. It mounts securely to my bike frame using the included bracket and Velcro strap, so I always have it handy during rides. Despite its compact size, it delivers powerful performance, inflating tyres efficiently without requiring excessive effort.The durable construction really stands out. The CNC-machined aluminum body with an anodized finish is not only corrosion-resistant but also has a premium feel. The anti-slip texture ensures a firm grip, and the dustproof cover keeps the valve clean and ready for use, even in rugged conditions.The added ball pump needle is a thoughtful bonus. It makes the pump versatile enough to inflate sports balls, which is great for multi-purpose use. Whether I’m on the trail or helping out with a soccer ball at the park, this pump covers all the bases.If there’s one minor drawback, it’s that the small size means it takes a bit longer to fully inflate larger tyres. However, for a portable pump, the convenience and performance outweigh this small trade-off.

I added this Mini Bike Pump to my second mountain bike. It seems to be great quality and functions nicely. It's small enough to not be in the way but does the work when stuck on the side of a trial. The pressure gauge seems to work well when airing up a tire. Overall, I'm very happy with this pump by Julai.

This is a really nicely made pump, that while not the absolute smallest or lightest, will do the job perfectly.The pump is made from aluminium and feels very sturdy. It locks closed to stop it popping open if you mount it to your bike. There is an enclosed mount which allows to fit it alongside a regular bottle cage.A rubber cap protects the valve, which itself is pulled out of the top of pump on a short flexible hose. This hose also has an inline pressure gauge, so you can see exactly how much air you've put into a tyre.When fully extended, the pump extends out from 20cm to 34cm meaning that each stroke gets more air into the tyre than some smaller pumps.The valve works with Presta and Schraeder, although note that for the former you need to unscrew the very end of the valve to get it to work.Ideally I think I prefer "clip on" valves because they run less risk of inadvertently unscrewing a valve core than with the "screw on" design this pump has. But I've not experienced that issue with this pump so far.

The feel , weight and quality of this pump seems okay . However for a non branded pump this is quite expensive . I have a Lezyn pump that cost less and is of tried and tested quality . Not sure that the pump is all it appears to be , I also do not like the textured feel of the pump in my hand .

I guess long gone are the days when you had a big tire pump sitting in the garage. My son just got into biking, and we dusted off my old mountain bike. Wanted him to have something since there is old rubber on the ground. I like the quality feel and the tiny size.My rating method:1 star - Avoid2 stars - Doesn't meet expectations on quality or materials3 stars - Meets expectations, but does not stand out, maybe costly compared to others4 stars - Exceeds expectations, something stands out, good value, recommended.5 stars - Awesome - blew it out of the park on quality, value - Highly recommended.

WHAT I LIKED:- Even though the pump is metal it is not slippy, it has little grip bumps- I like the built in gauge, that's a nice feature- Enjoy that you don't need to throw it in a pack as it installs under your water bottle cage keeping it out of the way but easy to accessWHAT I DIDN'T LIKE:- Not sure why it needed to be so heavy, I guess its to make it more durable, but for an emergency pump it could be much lighter-I could not get a good seal on any of my Presta valve bikes, worked on my daughter Schrader valve fine

pros Metal and well made. A simple unit that can easily be placed inside almost any bike accessory bag or use the include mount to attach to the frame. Textured grip surface on both sections of the pump. The sections seem to have a lock to keep them from flopping around.Cons The rubber end cap on my unit comes open if you look at it. The smallest touch will open it.Overall a good pump a a great replacement for the PLASTIC one I have now.

I didn’t know that bike pumps could be this nice and cool, like “secret agent” cool! This is definitely a quality, well-made do it all bike pump that conceals a pump, gauge, and flexible nozzle all in one tool! I love that this stealthy sits offset from a bike water bottle holder making it convenient and easy to get to, but also out-of-the-way! Definitely would recommend this as an essential piece of gear that is very understated and unassuming! Pulling this thing out, though would be super cool and definitely wow some friends! Highly recommend!

This is a well-made mini pump that seems targeted for use on high pressure road tires. It features a small diameter barrel, and a pressure gauge up to 160 psi.The aluminum design is solid in your hand. The top and bottom separate and connect with a twist of the two pieces. It doesn't lock when twisted - you have to feel the right position - which is easy. I really like the annular rings cut into the outside surfaces which provides good grip. I didn't notice any increase in temperature even when I took my tires up to nearly 100 psi.A small air hose is stored on one end of the pump body. The other end has the air vent. The hose features a screw on type connector/chuck that is adaptable to Schrader or Presta. For Presta the connection is quick and securely. And I didn't lose too much air taking it off. I prefer the screw on connector and hose over a one piece quick connect. Its more secure and leaks less. Also, the seal inside is simpler and last longer. But my favorite feature is being able to leave the pump hanging while I take a break from pumping. Threading on the chuck is more fiddley but not so bad.Below the air chuck is a short section of rubber hose which provides length and some flexibility. Following the rubber hose is the clear, rigid pressure gauge which connects the air hose to the pump body. The pressure gauge uses a calibrated spring to determine. The markings on the gauge are printed in black and are very small - bring your glasses. Luckily the O-ring inside the vial is orange. 90 to 100 psi is about the center point of the vial, so I just keep an eye on the orange ring.As you would expect with a mini pump it takes a lot of pumps to reach a high pressure. For me to increase the pressure from about 30 psi to 70 psi took about 220 pumps. An exercise in itself. This would be worse with a tire larger than the 28mm tubeless tires I use.Finally, I checked the accuracy of the little built-in gauge. I truthfully didn't have high expectations. What I hoped to see was consistency. In my test, the built-in gauge seemed to measure a little high. I needed to pump up to 100 psi to get a real 80 psi. Keep in mind the scaling on the gauge is small. The physical distance between 100 and 110 psi is about 1/16th of an inch. And the Orange O-ring used to seal the vial can get slightly stuck. In one test it seemed to jump from 90 psi to 100 psi. Note: I only saw this once.So, the pump is very well made. It's fairly light while feeling very solid - there is no flex when squeezing the sides. The texturing on the outside of the barrel provides a good grip. And the air hose works very well, the threading is very smooth, and it provides an airtight, secure attachment. I would say the absolute accuracy of the air gauge is not up to a separate handheld checker. But when fixing a flat on the side of the road it provides a better gauge than your thumb. For the quality provided, the price is very reasonable. Yes, it takes a lot of pumping, but this is a mini pump that is optimized for size and weight. Hopefully it doesn't get much use.

I've always wanted to add a portable pump to my cycling gear but was concerned about the weight it would add to the bike. This pump solves both problems. It's more powerful than I thought it would be for its small size, and adds hardly any weight to the bike. The mounting bracket that was included was easy to install and keeps the pump handy but out of the way. Fortunately, I have not had to use it on the trail yet, but I did use it to inflate my tires before I rode, and it works great. Very pleased with this purchase.

Very well engineered but also fiddly to use; has a unique method of differentiating between the two valve types, so need to work out how to set it up before having to mend a flat at the roadside! Really, quite unnecessarily complicated, but interesting engineering. The rather brief instructions mention a pressure gauge, but it does not appear to actually have one?
