Bike Pump, [Smart Valve] [120 PSI] Diyife Bicycle Pump with Gauge, Mini Bike Frame Pump, Portable Bike Tire Pump with Mounting Bracket for Road Mountain Bike Automatically Fit Presta Schrader, Black

Great little pump, Just what I needed at the right price.

Does what it says, although takes a while to pump up tyres due to short pump tube, that's the price you pay for portability.

Item was exactly how described

I bought this pump as I misplaced my older Topeak pump. Considering the low price, I didn't expect much. However, I was pleasantly surprised to find it inflated my bike tyres really well. The handle feels a little lightweight, and it'd be nice if it clicked into the body of the pump to stop it moving, but it doesn't actually move while I'm cycling so I guess that's not really an issue.It attaches and detaches to Schraeder valves much easier than my Topeak pump, and the gauge proved really useful (and fairly accurate). With my previous pump it was a pain having to keep detaching it and using a digital tyre pressure gauge to check the pressure, but it's so easy having it built in with this new pump.Fitment was very easy too. The pump is held to the side of the bolt holes (as opposed to directly above) which means you can use the holes to fit another accessory too, such as a water bottle. Again, this is something my old pump didn't have.All in all, very pleased. Though I've only used it for a few tyre inflations so far.I've since found my "lost" Topeak pump, but I'll be sticking with this one for the foreseeable and keeping my old pump as a backup.

The pump is OK for the price..doesn't exactly what it needs too...and starts to bike quite compact

I'm glad I purchased this. It gets the job done. The accessories are a good addition as well.

Dosnt work with the presta valves on my mountain bike, had to use an adaptor. Then it took over 400 pumps to fully inflate the tyre.The pressure gauge is small and difficult to read.

A lot of other reviews say this pump is hard to figure out how to use but mine didn't come with any instructions so it was almost impossible for me to figure it out. After about an hour of trying I managed to get it to work on some presta tubes but couldn't get it to work at all with schrader valves. The pressure guage works if I hold my thumb over the hole and pump but didn't move at all while I was pumping up the presta valves and it took a very long time to inflate, not much air came out at all. Like all the other reviews said it's probably mostly user error but I've used universal pumps before and by far this is the most difficult to figure out I've ever seen and takes the longest to pump up. Nice idea and I really wanted it to work well but without the instructions I just can't get it to work properly. My tyres are inflated now though so it wasn't all bad.Edit: Gave the pump to my brother when I bought a new one, works with no issues at all on his bike. Still doesn't work on any of mine, sad times.
