GIYOMini 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

Pumps it up, pressure gauge seems to be fairly accurate. Doesn't leak air. It's lightweight. Takes a while to pump up but it's tiny so that's to be expected. The way the lock mechanism works is opposite than I expected but it makes sense being it's a compact portable design.

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!

Good pump, easy to use. However, I did not realize how much elbow grease would be going into pumping my road bike tires up after being stored all winter. I’m pretty dang fit and my arms were getting a PUMP between 70-80psi. I gave up at 80, but luckily had a Ryobi pump with a Presta adapter that worked perfectly to get my tires between 100-130psi with an easy push of a button.Guessing this would be good for emergencies to pump tires enough to avoid further damage and get where I need to.The gauge works fairly well and the pump itself I have no complaints about. Will keep for emergencies, sports balls, etc.I have not yet used the patches, but nice little bonus.

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

Pequeño y poderoso

Good in a pinch or on the go, but not the best replacement for a traditional pump. There's so much resistance that my hands get tired pumping almost immediately. The gauge maybe works, maybe it doesn't... There doesn't seem to be any way to really tell. I felt the tires on my bike though and could tell they were inflating, but not sure if it was enough, too much, just right...

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.

Purchased a new one to handle new presta valve. It works but takes for ever to pump to 50 psi. Ok for bike bag and emergency only. Will need to buy a better / larger pump or set for air compressor. All small pumps might have this issue.
