Customers say
Customers find the pump works well with presta valves and appreciate its compact size and ease of use compared to hand pumps and CO2 cartridges. The pump inflates tires quickly, with one customer noting it inflates at 1 pound per second, and they consider it a great tool. The charge retention and pressure gauge features receive mixed feedback – while some say it recharges quickly and the gauge is spot on, others report it doesn't keep a charge and the gauge is unreliable. Customers consider the product expensive.

Awesome little gadget! It's much smaller than my excellent Cannondale mechanical mini pump and easily fits in my seat bag. It's also a touch lighter (116 g for the Cycplus pump vs 119 for my mechanical pump). The unexpectedly cool thing is how easy and quick it is to use. I unzip my seat bag, pull out the pump, press the button to turn it on, just press onto the valve, then double-press it to start inflating. I feel this is much quicker than undoing the strap of my mechanical pump and extending the short inflating hose. From memory, it takes 20 seconds to completely inflate my 700c x 32 tires to 60 psi. In fact, I had a slow leak in a tire recently and I could re-inflate it and get back on my bike while waiting for a red light to change. I probably inflated the tire from 25 to 50 psi. Of course, since it's battery-powered, the negatives are that a) you have to make sure it's charged and b) you can't pump tires forever with it. I've never had it run out of battery on my, but I did get the red low-battery indicator after 4 times pumping my 700 x 32 tires to about 50 psi. Compared to a CO2 inflator though (how many spare cartridges do you carry?), I think this one's a no-brainer.
A friend of mine was showing off his Cycplus pump, bragging as guys do about his new tool. Careful about bragging because later in the day we were fixing a flat on the trail, and he reminded us that he had the Cycplus pump. It worked great, taking a 29"x 2.3 MTB tire to typical pressure in about one minute. Having seen that, I ordered two of them as stocking stuffers. The pump is in a nice little box with an extension hose about 5" long for using on Schrader valves, and it has a ziplock bag for storage to keep water away. I'll be purchasing another of these for my personal pack soon.

The AS20 PRO Model works Great, I was able to inflate 2 tires from 20 psi to 80 one charge and had plenty of charge left over to do another one. I recommend this pump over the cheaper AS20 base model, as it works great. I love the additional pump nose too, which does not come with the base model AS20. This is a great little pump and much easier to use than a hand pump.
This pump is not a necessity, but if you are running TPU tubes, it's either a hand pump or this. CO2 and TPU don't go well together with cold and plastic you'll get a snap crackel pop! The unit is nice being able to set your pressure and inflated to what you need. No guessing, thumb guessing, or carrying a gauge. All in one! Small, light weight and fits in a jersey pocket just fine. Definitely play with it at home to get an understanding of how it works. Hands on vs out on the road when you are already chasing daylight, lol.
I was really looking forward to having this tool as it’s smaller and lighter than my current portable pump. However, it has been a constant let down. It works great at deflating my tires but not so much pumping them up. Takes a long time before it auto turns off and come to find out it’s just the battery (fully charged) that has died and not an indication of my tire being inflated. Was too expensive to not work. Had high hopes but I am now out $60 and back to my bulky pump.
Seems to be high quality. Yes, it's noisy, but that doesn't matter to me. It gets a little warm but not excessively hot. Inflates faster than I would expect. I have been charging it after each use, I haven't used the battery completely yet. There is no gauge or display, but I favor that for simplicity and durability.
This little pump is amazing. It is smaller and lighter than a hand pump or CO2 cartridge set up. It will inflate more than one tire on any of the bikes that I have and recharging it is quick. I have used it on my own tires on road bikes, mountain bikes, and even a fat tire bike. It won’t do much more than one fat tire, but that’s a lot of air. On a number of occassions, I have stopped to help other bikers with flats. All of these riders want to get one of these for themselves. The ease of converting from presta to Schroeder is another plus. I love it.
Die Minipumpe für mein Fahrrad hat mich auf ganzer Linie überzeugt! Ihr geringes Gewicht und der kompakte Formfaktor machen sie zu einem idealen Begleiter für unterwegs. Sie ist so leicht, dass man sie kaum bemerkt, und passt perfekt in die Trikottasche, ohne zu stören. Die Handhabung ist ebenfalls sehr einfach. Trotz der kleinen Größe ist die Pumpe erstaunlich leistungsstark und ermöglicht es, den Reifen schnell und mühelos aufzupumpen. Besonders gefallen hat mir, wie unkompliziert sie zu verstauen ist – kein lästiges Herumfummeln oder sperriges Gepäck, einfach in die Trikottasche schieben und los geht’s. Insgesamt eine top Minipumpe, die durch ihre leichte Bauweise, einfache Handhabung und praktische Größe besticht. Für jeden, der eine unauffällige und dennoch effektive Lösung für unterwegs sucht, ist diese Pumpe definitiv eine Empfehlung wert!
Incroyablement surpris par le résultat du gonflage il est peut-être un peu cher pour ce que c’est mais je vous le recommande si vous recherchez un bon petit gonfleur 👌
Highly reliable inflation with target pressures accurate to the PSI. I only use a pump now when my tires are fully deflated, otherwise this tool is better and quicker to top up the pressure before a ride. Charge it with usb-c in the car once in a while is enough to keep it going.
A quality make with a solid touch and feel experiance. super small sized pump that fits in every toolbox. It can fill up your bike tyres from zero to 6 bar quickly before it needs to be recharged. Fully charged you fill up three tyres and it is recharged in less than 30mins – very convenient.
