GIYOSmall Bike tire Pump Schrader & Presta Valve for MTB 80 PSI Telescopic Barrel All Metal CNC Portable Mini Bike Pump Secure Valve Lock for Easy Pumping | Taiwan Made GM043

Love this pump, so small it fits in all my bicycle tool bags.

Before I really get into this, I need to say that, I had practiced on just a tube, no bike or tire weight,man or man did that little thing pump up a tube. I had opened this up from the box and was checking everything out and pieces fell off of it. I thought maybe it was just something for shipping to not prevent it from damage. So I tried for a few hours to get it to clamp on and it wouldn`t clamp on and I couldn`t get it to pump at all. I thought it was junk, so it went into non- food trash can, so it didn get dirty and threw it away.It drove me nuts, so I went and dragged it out if the trash and decided to look at the picture called instructions and the piece I thought was to keep it from bouncing around was actually a the piece that clamps the pump to the stem. So when I figured everything out and that little thing just kicked some flat tube butt, but as I said before, I have not tried it on the full bike and tires, weight. I do have a 60+ lb bike. I might have a different thought after trying to pump up the tire at a later date, with 2 -15 lb. dogs and a heavy basket and all the small extras I have on my bike, which might bring it close to 70 lbs. I had bought this one, for I had an old one,but I couldn`t find the screw in stem and as this one was in the mail, I did find everything for the old bike pump,but one bad thing about the old pump, you have to screw this onto the stem and after your at your full capacity, you have to unscrew it and you end up loosing some of the air. It`s zip tied to my bike for an emergency. I`m no way regretting getting this little one, I`ll just put it in a bike satchel, I won`t need the frame attachment. I love that it is so small and it will fit anywhere.

Great for extreme space saving, and metal madeHeavier than some of my plastic mini pumps that are 3 time its sizeDifficult to pump high psi tires

Hard to figure out the quality of a product in pictures. I was hesitant buying it at first but now seeing it and holding it in my hands I can say that the quality of this pump exceeds the expectations. This is a super compact 5 inch pocket pump excellent for the mountain biking folks anxious of carrying a CO2 inflator on the trails and in the meantime hate the bulkiness of an old trusty pump.

This manual pump couldn't be much smaller. It does a remarkable job with minimal effort.smooth as polished glass. Beautifully manufactured. Kudos to the engineers and the people who made this little "Gem".

I've had 2 of these for about 6 months. The first time I got a puncture and actually had to use it, it pulled into 2 pieces. Luckily I also had a couple co2 with me. The other one seems fine... poor quality control. I would've been stranded 30 miles from home with a flat had I solely relied on this pump.

This little pump is great for my rides where I like to let out the air a little on the single track, but then like to blow up my tires when I have to ride on the roads back home. It's compact and well built. The maximum pressure of 80 psi means I can't carry it on my road bike, but for my low pressure tubeless gravel, it's perfect.
