CYCPLUS 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 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!

Bought this to take on a touring trip. For the hotels that didn't allow bikes we had to deflate the tires to put the bikes in bags. Holy hell did this little pump save us from sore arms. One charge easily inflated 4 road tires. I was running 28c at 70 psi my buddy 30c at 55 front 60 psi rear.I will never ride without this little pump, the gauge works great, it's tiny and weighs less than my Silca gravelero. It always finished charging in the time it took us to repack our bags and never ran out of juice

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 ride with a friend that uses one of these. After loading the truck for a ride last month, I wanted to try and slim down my kit. This things works very well. We ride tubeless 32's at 60psi, 30 - 45 seconds from less than 20 to target pressure. It is a little noisy and gets warm, but it is the size of 2 tic tac boxes. Pretty amazing

Small and powerful, great for carrying in my pack. Much easier to use and carry than a micro pump. Has been a lifesaver on many mtb rides

This is a nice, handheld air pump for bicycle and small inflatables. I'm able to get 4 fat tires (20"x3") inflated quickly on a single charge. It pumps up the tires rather quickly and stops at the designated pressure setting.

Nice little pump. I ride tubeless, and the valve stems give many hand pumps fits with leakage or pulling the valve core out while trying to detach the hose. If you put the stem at the bottom, and press firmly, this fills the tire to the set pressure without leakage. I can get 2 fills. Several comments about "not waterproof", but you need a route for air to get in and out of the pump, and you can't really make either waterproof. The rest of the unit is well sealed.

This is a great little unit. The only thing I didn't get from the reviews and promos is that it screws on to the presta valve -- it won't work if you just push on it. That makes it a little easier to deal with (see the screen, etc), but I have had problems with other pumps that unscrew the valve core when disconnecting the pump. It has NOT happened with this so far, but if it does, I will come back and report.The other thing is that it cannot "read" the pressure when not pumping (maybe for a schraeder valve it could), so it isn't really a replacement for a passive gauge.
