Review: Works Like It Should. Great Customer Service! - Easy to use, compact, and great customer service. MyAS2 PRO Tiny died after almost 1 year of occasional use with a persistent EE2 error. I reported it via email to the manufacturer using the OEM website late on a Monday night. I woke up Tuesday to troubleshooting instructions and a request for a video of what it was doing. I replied late Tuesday and woke up Wednesday with emails saying it wasn't repairable and confirming replacement under the OEM 2-yr warranty. The new one arrived Friday! Less than 90 hours from first report to replacement. Outstanding! After the replacement, I ordered a second one as a gift to a new cyclist. Oh, the gauge is accurate compared to a Silca gauge and the inflation speed is "plenty fast enough." The batteries recharge quick too.
Review: Compact Electric Bike Pump Works Great! - This Cycplus bike pump checks all the boxes: It's very compact and easy to carry ... It's extremely easy to use ... The battery life is excellent ... And it inflates bike tires to a set pressure very quickly! I'm very satisfied with the quality and the overall design of the pump ... Nice device for any bike rider!

### ⭐⭐⭐⭐⭐ Small, efficient, and works to seat tubeless tires
*by B***V on March 24, 2026*

I wasn't sure what to expect with this, as it seemed like a gimmicky thing that would never work as it was advertised. However, I loathe using mini pumps, and C02 pumps are a pain to carry and not always advised for certain setups. I've now had this thing for a bit and have used it to top off my tires, inflate new tubes, and also to seat tubeless tires on tubeless rims on four tires now, without issues. Overall, the size if this thing is surprisingly small, and it packs in any of my bike bags easily. It feels sturdy in the hand and like it could take a few drops on a hard floor. Installation for inflating tires with Presta valves can be a little tricky, as you've got to seat it down pretty hard on the valve to seal the opening. Also, do not try to seat your tubeless tires with the valve core removed. When I tried that, air just kept escaping. Putting the valve core back in allowed me to get the magic ping as I inflated the tires. No need for an air compressor! And I would say the complaints of the noise level on this thing are a bit exaggerated. Sure, it's not the most pleasant sound, but definitely better than an air compressor. I have not yet verified the accuracy of the built-in gauge, but it is super handy to have a gauge on-hand that is built into the pump. I will say that I was able to inflate two 2.3" 650b tires with tubes, then later seat those tires when converted to tubeless before I had to charge it again. For a ride where you might need to top off your tires, and worst case re-inflate after a patch or tube change, it should be more than adequate. My only complaint is the buttons and placement of the screen. As someone with CMC joint arthritis, pushing the buttons in or holding them down to pump tires is a painful and awkward affair. The screen can be hard to see depending on your vantage point, but I guess there is not really a better place to put it where it would work ambidextrously. Overall, this was a worthwhile purchase and I feel super happy it works to seat tubeless tires.
