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

Quick review. I’ve been watching these auto pump devices, finally pulled the trigger. This is a great device and I’m really enjoying it. I road biker 7k a year for context.Comments:1. Weight. Weight is equal to my 2xco2 cylinders in the saddle bag plus adapter. Perfect!2. Number of inflations: remember that with a co2 cylinder you’ve got one chance…so ya gotta carry two. With this device, the range is 2 to 4 full inflations. Done! And if you’re just checking or topping off pressure, it’s a trivial reduction in battery.3. Size. Same size or less than 2 co2 cartridges plus adapter. Nice little plastic bag included is a nice touch to assure it’s dry for wet rides.4. TPU tubes!!: on the mnfr site, they state to use the attachment extender tube. I only ride tubolito tpu tubes (love them). No issue at all si ce you’re usually not doing a full inflation, and no heat appreciably generated. But carrying the extender tube is the simple solution for a total flat. Done!! Viva La tpu tubolitos!5. Pressure indicator screen. Done! This is the game changer as it removes all doubt if inflated pressure. Better, you can now use it to “top off” pressure on a ride on those days you forgot to check tire pressure before starting ride or after hitting a hole. Sweet! The unit shuts off automatically at the pre designated pressure. Check it out! I’m not using my floor pump anymore cause I just grab this from the saddle bag, top off pressures at exact number, and off I go (placing the unit back in the saddle bag). This is the game changer.One more, 6. Screen location. I saw one YouTube review where the dude criticized the unit due to the screen and exit pump hole being on opposite sides of unit. Yeesh! Dude, roll the valve to 6 o’clock on the wheel position, attach pump directly, and you’re looking directly at the pressure screen while it runs your pressure!! Awesome. Not sure why he didn’t think of that.Bottomline: use this one time on the road to inflate a flat quickly and accurately and you’re done. Great price point for the functions above and peace of mind. Love it!

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.

I purchased both the AS2 Pro and the AS2 Pro Max mainly to see their size differences and which I could incorporate into my small seat pack. I already knew the Pro Max would be larger, but how much was the question. Then after a bit more review research I decided that the Pro Max would be my best option overall as I could also use it with my motorcycle where the Pro was not recommended for that. So, I purchased a slightly larger seat pack and all is well in my world.These are really great units though, either way. And if your just biking the smaller, lower cost Pro will work just fine. Small, super easy to use and a great peace of mind to have on board.

I was almost on the verge of sending this item back as everytime I used it on a presta valve it wasn't working properly. No matter what angle or if I used the attached flexible nozzle. Finally right before I was about to box it up and send it back I tried it one last time and I realized that the nozzle on the end of the attachment was threaded. So I threaded it onto my presta valve and then it worked like a charm. No where does it say anywhere (that I can find) that the nozzle has to be screwed on. All my other bike pumps the nozzle just presses on. I hope by leaving this review it can help others. Unless of course I'm the only one who had this problem. It is small which I like and the USB C charging is great since it can work with my Phone battery back up.

Great little product. Does what it is supposed to do — and so far with no problems. Quick charging, I use it to maintain my tire pressures prior to my rides. Really easy: turn it on, set the desired pressure, place over valve and press on button to start pump. It turns off automatically when pressure is reached. My top-offs take 5 sec. Fits in my saddle bag with my multitool and tire repair kit. I often support other riders so also carry co2 (for now). I run tubeless 700x 45.

This little thing gets the job done well and has great functionality with a simple and clean UI. Plenty of battery life for multiple fills from empty on 29" MTB tires. Better than carrying a couple of CO2s. It seems well built and the included accessories are solid and useful. I have converted to Clik cores recently and I added a Clik chuck to this compressor. It's a super convenient combination for fast top offs.
