CYCPLUS AS2 PRO Tiny Bicycle Pump with Gauge, Max 120 PSI Electric Mini Pump, Auto Stop, with Presta and Schrader Valve for E-Bike, MTB, and Road Bike (2025 Updated Version)

The CYCPLUS tiny electric pump is a surprisingly capable tool in a very compact form. I’ve used it for my road bike (high-pressure presta tires), and it handled without issue. It reaches the advertised PSI (up to 150) and shuts off automatically at the set pressure, which is a big plus. Battery life is solid, I’ve gotten multiple inflations on a single charge. Build quality is excellent, and it fits easily in a jersey pocket or saddle bag. It’s a great emergency pump for cyclists who want an alternative to CO2 cartridges or manual pumps. The digital gauge is reasonably accurate, and it charges via USB-C, which is convenient. Highly recommended for anyone looking for a reliable, portable inflation solution on the go.

This little pump is amazing and doesn't take up much space in my bike bag. It pumps up quickly and precisely - which i love! Pick the amount of pressure and it pumps until it hits the target. I run tubeless on my road bike and it does great! I use it to pump up other riders tube/tires which requires more pressure - but no problem! This is a great little pump and worth every dollar!

I’ve been using this pump regularly for months. I use it every day to top up my tubeless 700x19 presta tires before riding as seen in the video. It’s small and carries nicely in my jersey pocket, is relatively light, and well made. There’s more than enough battery to inflate the tires a couple of times. It charges quickly so I top up the tires, put it back on the charger, finish getting ready to ride (5-10 minutes), and then put the fully charged pump in my jersey pocket. I also use it to top up my motorcycle tires. It can add ~3 psi in about 2 minutes into a 195/55-17. I don’t rely on it to reinflate that tire; I carry a 12V pump that runs off the motorcycle battery for that. While it can get hot when running for a minute or so, the included form fitting cover buffers the heat and stays on the unit all the time.

These pumps are all the rage now, and this is a great affordable and high performing option. I've been using this for nearly a year, and it's been rock-solid. The buttons could be bigger, but that's not enough of a factor to take a star off, especially considering the pricepoint compared to other options. I use mine to maintain pressure in spare wheelsets so the sealant doesn't dry out. I use it exclusively on presta valves (no experience with cchrader). It inflates quickly, the auto-stop is a nice feature, and it charges quickly. I do recommend the version with the digital pressure screen.

Only a couple uses so far. Works as advertised. Definitely small enough to replace the manual hand pump and works well for pre ride top offs. Only drawback is the noise. But it's a fair trade off given the convenience.

This device works really well. It’s small, it’s light, it has an digital inflation gauge that you set to your desired PSI, you inflate your bike tires, and the electronic pump automatically shuts down when the PSI is reached. Perfect. I used to carry 3 C02 cartridges and an inflation device for flats while on rides. The new pump is more compact and lighter than my previous C02 stuff. Ordering was easy, delivery came quickly. The device and accessories were packed in a small but protective box. Great all around purchase.

OK I love this thing. I have used this for a week long trip as my sole inflator on two bikes daily. I have stopped on the side of the road and helped 3 people with flats. Love that you simply put the PSI in and press button and stops automatically. Gets hot if charging from no PSI. Liked it so much I bought a large model cycplus for daily use in the garage and got rid of a larger compressor

Awesome little pump! Small, very accurate, and powerful, it’s simple to set your exact desired tire inflation, and top them off quickly and efficiently. Size makes it easy to carry in a bike pack, forget about carrying CO2 cartridges. Works great with both tubeless and tube bike tires. Great battery life.

Digital display valuable to optimise pressure for ground conditions your riding on, easy to use light weight to keep with you battery power good. Value for money i have 2 cycles with different valves easy to adapt between the 2 making it functionaly.

+ Bra batteri. Tillräckligt snabb. Bra display och lätt att ställa in önskat tryck. - Aningen stor. Inte vattentät. Aningen dyr.

Great little pump. Fast but compact. Loud as heck though, but that's typical for all micro pumps. Already used it for multiple punctures and to top up my tires between rides.

ottimo, piccolo e compatto, pratico, bellissimo. solo un po rumoroso quando si usa.

Klein, Leicht, Leistungsstark, gut verarbeitet. Passt perfekt in die Tasche meines Rennradjerseys, reicht für zwei Rennradreifen aufzupumpen problemlos, schafft ordentlich Druck (selbst Drücke den heutzutage kaum noch jemand auf dem Rennrad fährt), kommt auch mit MTB-Reifen klar, gibt nix zu meckern. Und wenn man sie im Angebot bekommt auch ein echtes Schnäppchen, ggü. den klobigen und minderwertigen Alternativen, die auf den ersten Blick preiswerter erscheinen, aber nur billig sind.
