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.

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.

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.

Works as advertised. I wanted a pump to top off shrader valve bike tires that could press on rather than screw on. That feature works for the tires I have. I have 2 bikes, one with tires topping out at 80 PSI (a hybrid type bike) and a beach cruiser with bigger volume tires topping out at 60 PSI. Topped off the 80 tires which both started at about 30 and then did a partial fill of one of the 60s (started about 30, pump battery died at about 45). Recharged and finished first 60 tire (started about 45) and then filled the second 60 tire (starting about 30). Can’t hear if any leakage of air since pump is so noisy, but it takes a couple minutes to fill. Shut off feature works when appropriate pressure reached. I could see the digital readout pretty well with the valve stem about 9 or 3 o’clock, which allowed me to use one hand to hold it in place while gripping the tire and without having to bend over further if valvestem at the bottom. Unit does get quite hot, but OK to handle with the included silicon sleeve. Not sure how it would do trying to fill a new tube from flat. I will likely use it as I intended for partial fills and as a backup on rides after using a CO2 cartridge to start. Four star rating for now since I would not trust it completely for a ride as my only way to pump up a replaced tube after a flat.

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!

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.

The media could not be loaded. 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.

The CYCPLUS Tiny Bicycle Pump with Gauge works admirably for restoring road pressure of around 60psi to my 2.5 inch e-bike tires following an off-road outing under reduced pressure of around 20-25 psi. I have learned that restoring pressure with my mini-pump is both more time consuming and labor intensive that I want to deal with following an arduous off-road ride. Enter the CYPLUS bicycle pump. Set the desired pressure, attach the pump to the valve and stand back. It will produce an audible "buzz" as it runs but will automatically turn off when the desired pressure is reached. I can probably get three inflations from it with these large-capacity tires under the scenario I described. It is tiny and convenient but in a perfect world, I'd like it to be slightly larger for greater battery capacity, admittedly, a selfish ask on my part. For most uses this little guy is perfect for a weight-conscious roadie, gravel, or mountain bike rider. After only a few uses the initial sticker shock of its cost will disappear and you'll wonder why you didn't get one sooner.
