- 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)

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!

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.

I bought the pump a year ago and it worked great, very small, easy to use, very fast inflation. Once, I even inflated three tires during a bike ride (more powerfull than advertised). Unfortunately, its battery died last month. I contacted customer support, sent a video, and received a new pump version 2025 in just three days. I'm very happy with both the product and the service!

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.

Works surprisingly well! I have not pumped tires from full flat yet to see how much actual battery life it has, but very impressed with quality! Rather expensive, but it replaced a much larger pump in my trunk bag and gives me much more carry space. Nice to have in my bag when I’m 20 miles from home!

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

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.

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.
