This is the bike pump to carry!
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.

Compact, Powerful, and Perfect for Roadside Inflation
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.

Excellent Backup Pump — Compact, Precise, and Surprisingly Powerful
The media could not be loaded. I really love this little pump! I use it as a backup inflation solution on my Canyon Speedmax triathlon bike with tubeless tires, and it fits perfectly in the bike’s frame-integrated toolbox—a major win for space-saving.The connection to a Presta valve is seamless: just push it on—no twisting, no fuss—and it forms a nice, tight seal. The electronic screen version is well worth the slight price increase, offering easy controls and accurate PSI readouts so you know exactly where your pressure is, with not much of an increase in size and weight. That peace of mind alone is a huge bonus.Yes, it’s pretty loud (especially indoors), but it fills quickly, especially up to the 60-65 PSI range I use for my tubeless tires. It can take a little longer getting up to 100 PSI for my clinchers, but for a pump this small, that's expected.I personally use this for emergency roadside inflation only. Day-to-day, I rely on the larger Cycplus "Electric Air Compressor Portable Bicycle Pump Car Tire Inflator" at home. But the beauty of this model is that I no longer need to carry CO2 cartridges or adapters. (Okay—full honesty: I still carry CO2 during Ironman races because I'm overly cautious. But that's me, this pump could be your only solution.)In short: compact, capable, and incredibly convenient. This little device makes bike prep and packout simpler and lighter—what more could you want?

Tiny but handy... AND LOUD
It's loud, but it works amazingly well. Definitely saves space over a traditional pump. Battery life when inflating from zero lasts for about 2 700cx28 tires (73psi). Topping off before a ride once at pressure is quick and easy. The built in gauge is fairly accurate. The short piece of inflation hose is handy for hands free operations. Recommend highly.

Works well, limited battery life, gets hot
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.

Get this pump and stop using CO2 cartridges!
I am an old(er) cyclist. During my 50+ years of cycling I have seen many new cycling products, claiming to be the best thing since sliced bread, come and go. I can safely say that these mini-inflator e-pumps are truly a game changer. No more need to carry CO2 cartridges. No more adding to the local landfill with spent cartridges. No more having to deal with CO2 inflators that are often finicky causing the loss of an entire cartridge. No more frozen fingers as CO2 cartridge release their gas. Let me cut to the chase. On a recent 60 miles ride I had three punctures. It is goathead season around here and the particular road that I was on gets its fair share of those little devils. I was able to fix and fully inflate all three punctures up to 75 psi. I still had one more bar showing on the digital display. I guess that if I had one more flat I would have to use my back-up pocket mini-pump. But that would have been OK. This pump is well made, it works fast, the noise level is minimal, especially out on the open road, the digital gauge is a plus and it fits just right in my saddle bag where two CO2 cartridgesand the inflator valve formerly resided. If you want a well-made pump that works well, backed by a company with good experience in the field, and all at a reasonable price, look no further, this is YOUR pump. You don’t need to go to another manufacturer, pay more for their fancy-named product and wait in line because the owner cannot figure how to sell his pumps in the USA. Get this pump, you will not regret it.
