CYCPLUS AS2 Tiny Pump Bike Pump Portable Ultra-Mini 100PSI Electric Bicycle Pump Type-C Rechargeable Battery, No Pressure Display(Winner of The EUROBIKE Award 2023)

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.

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.

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 sucks. I could not get it to inflate beyond 22 psi even on one tire. Amazon should require an independent test certification before allowing the sale. Too many failures, and regardless of return policy, it’s a waste of our time.

I was busier than a pair of jumper cables at a redneck wedding when this thing showed up, so it sat in the box for a few days (maybe a week) before I finally got around to opening it. When I did, the thing wouldn’t turn on. I plugged it into a charger and within a couple minutes it stopped charging because, apparently, it was already pretty much full when it arrived. Still wouldn’t power up. So I cracked open the manual and figured out the secret handshake required to turn it on. Hopefully I remember that little ritual the next time I’m on the side of the road needing it. I had a bike hanging on the wall with a tire that had gone flat from a slow leak—because I’m too lazy to swap the tube after one of those half useless stick-on patches failed to seal. This pump aired it up quick. I just used my fingers on the tire to decide when to quit. The tire’s rated for 115 psi, and I’m pretty sure this thing would’ve happily blown it clean off the rim if I’d kept going, but I didn’t see any reason to test that theory. Once it was harder than algebra to a third grader, I called it good. It fits nicely in my saddle bag or a jersey pocket. As long as I remember to actually bring the thing with me, I’m pretty confident this pump, a spare tube, and one of those questionable stick-on patches will save me from having to make the call of shame and ask my wife to come pick me up.

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.

Small and powerful. Works great, especially when adding a pound or two between rides. Easy to carry.

Purchased because it was small and light, but it dies after filling up 1 tire, it’s really loud, and there is no display of pressure. Essentially an electric Co2 I guess. I ended up getting a different brand

Jak na początek wszystko działa dobrze.

Good instructions comes with it. Easy to use and very powerful. 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!

La pompa è perfettamente funzionale al suo scopo, gonfia, con una carica, minimo due pneumatici da MTB a 3 atm oppure tre da bici da corsa a 6 atm perfetta e minimamente ingombrante (sta nel palmo di una mano) ed è molto leggera anche da mettere in caso nella tasca dietro della maglia da biker, oppure nel contenitore attrezzi fatto a borraccia. Consigliata

Neat and easy to handle. NOICY!!!
