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

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!

Its a little small but perfect for my 8yr old grandson

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.

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've used this on both shrader and presta valves locked on well and no need to change out the end. Super nice to have the pressure gauge on the pump and it seemed to be accurate. Used it to pump up my ebike 26/4 tire. Took awhile but it would work in an emergency. Mounting was easy on bottle cage holes. Handle has a hole to lock it into mount. I would advise mounting it handle down
