Mini Bike Pump - Portable Micro Frame Pump with Pressure Gauge, 100PSI High Pressure Biking Mountain Bicycle Tire Pump Accessories Fits Presta & Schrader Valve

Small and easy to use

I purchased this pump to put on the bike I was using for a triathlon. Having never done this before, I wanted to make sure I had the equipment I needed, but also did not want to pay a lot for it. This pump worked well, and I was able to top off my tires to 100 lbs before my rides. Because of its size, it took more time than I thought it should have to bring the tires up to pressure. But worked perfect for what I needed it to.

Works as the description says and came with instructions and aired up my tires 24 times already

The plastic tip when inserting into Shrader valve broke rendering the pump completely useless on my second use. FYI: the gauge is also not accurate or can be visibly sen another useless "option" . Amazon needs to discontinue the sale off this for its integrity to its "Prime" or any other customer ...

I bought this several months ago but just had a chance to use it now. There were no instructions on how to use it other than what’s on the Amazon page, so it took awhile to figure it out. I have never had a bike that had a presta valve before and had to watch a YouTube video on how to put air in my tires. After I figured it out (you have to unscrew the top of the presta valve to allow air in) it was super simple to use this pump. So simple that I didn’t think air was going in my tires. After a few quick pumps, my tires were full again! I love this little gadget! It will come in handy for my daughter who will be going to college. It’s light and portable so she can have it with her wherever she goes. The only reason I didn’t give it a 5 is because it’s a little difficult to remove the top to change it the valve settings, otherwise it’s great! I’m glad I purchased it.

Wife loves it mounted directly to her bike easy to use high pressure and expensive enough

Perfect size for carrying on rides.

I love this pump. It's compact and works great. The reason I gave it four stars is that the spring inside the valve port became bent or "tweaked" after a few uses, which made it hard if not impossible for me to use it on a Presta valve.But I have other tubes with Schrader valves and Presta/Schrader valve adapters so it's not a big deal.
