GIYO Mini Bike Pump, Portable Compact Bicycle Pump with Pressure Gauge, Tire Repair Kit, Perfect for Presta & Schrader Frame Mount for Road, Mountain & BMX Cycling, Ball Pump with Needle 120 PSI

10 out of 10 was at a boxing event at the local agricultural center and a stranger in a escalade had a slow leak flat tire and I was like hey I got a tiny pump in the car it’s worth a shot. Was able to pump up his tire after about 10mins so that he could drive home. I was mind blown. I bought two more an had a extra for myself and gifted the other.

I travel with my bike a lot on airplane, and this has being a life saver for me, since you can't bring the CO2 with you and I always forget to buy some on the city I am visiting. This is a lightweight pump, fits tight on my road bike, doesn't rattle and does the job. I had more than 10 flat tires last year so I've been using it constantly. Worked so well that I decided to get another one for my other gravel bike. Great purchase for the bang!

The pump and the pressure gauge work and its super small and lightweight. The pressure gauge is not terribly accurate just from the type of gauge it is but if you fine with +/- 5 psi it shouldn't be too bad. Its better than having one the same size without any gauge. It's super easy easy to pump past 20 psi or so and you will get a bicep work out from the reps alone but it will get you to 35 psi on a bike tire in a few minutes.

I decided to buy a small pump after I recently fixed a flat and used C02 cartridges to reinflate my tire. With those, it was impossible to get the air pressure right. I found this pump and have been pleased with it. I tested it by deflating a tire and then pumping it back up. That only took a few minutes, and the gauge showed me when I had the pressure at the right level. After that test, I was sure I wanted to keep the pump, so I mounted it on my bike. That only took a minute. I removed one of my water bottle holders, slid the mounting bracket into place, and put the bottle holder over it. The pump snaps in, close to my bike frame where my leg isn't hitting it. I was glad I didn't have to get rid of one of my bottles, since I need two on longer rides. Now I'll be ready the next time I'm faced with a flat tire!

Nice compact size. Does have a decent psi gauge. Would probably take awhile to fill a large fat tire bike but it's better than nothing. Also has a patch kit, would be better if patch kit had some way to store it, but for now we put them in a ziplock bag

Pump functions fine but is definitely not accurate. Also the handle doesn’t stay in place while riding which doesn’t cause any problems other than I don’t like how it looks

I purchased this pump after losing my previous one. What I like about it is (a) it's small but (b) it still has a pressure gauge on it. Not as easy to inflate tires as with a floor pump, but then it's hard to carry a floor pump on a ride. The few times I've had to use this - primarily when others on a ride had a flat - it was more than adequate to the task. I'd recommend it to any serious (or even non-serious) bike rider.

It's lightweight and it fits on the bike with no problem. Once you get to around 80Ps.I it becomes unbelievably hard to pump. That being said it will do every bit of 110 psi.
