BV Mini Bike Pump Portable Frame Pump, Shock Pump for Bike Shock, Air Ball Pump Inflator with Ball Pump Needles, Mini Pump Fits Presta & Schrader- Smart Valve

Product works very well, size is great to carry in backpack, very quite when using and holds the air pressure fantastic. Makes a slight sound but overall great product.

absolutely amazing bike pump on the go, especially for road bike or fixed gear. whether you want to screw it to ur bike with easy access or carry it with you in your bag it’s very lightweight and small to fit almost any carry. The ability to use it for schrader and presta valve is also very helpful and the pump doesn’t take too much pumps to fill an empty tire or tube’s air. Just 6-7 strong pumps and almost all road bike or fixed gear tires should be full.

What can I say? It’s an inexpensive portable bike pump. The rubber component is fragile, so be careful with that. I broke mine day one. Still works just fine, just the small piece that attaches it to the pump snapped.All in all, I’m satisfied with it. Definitely comes in handy when on the road.

I used it to pump up 1 FAT bike tire from 0psi. I was quite suprised at how well it worked on low pressure FAT tires, since this is obviously a high pressure pump for road bike tires. It took about 400 strokes to fill a 20"X4" FAT tire to 14psi.(desired psi) It took no effort to push the pump strokes. This is a good compromise for a FAT tire pump. A true FAT tire pump would be much larger diameter....but that ain't gonna fit in the saddle is it?. I carry it with confidence that it is a good solution for emergency FAT tire repair.

So far so good. Does the job!

Does not work on presta valves, Schrader only. Other than that, it’s a pretty good pump, although a bit hard to read the pressure.

This is a really good little hand pump to have in your backpack or strapped to your bike.Pros:- Easy to get the hang of it- Pumps a surprisingly good volume of air pretty quickly- Pretty solid build quality for the price- Compact, looks cool and is a lifesaver for the moments when you're on the road and need something fast and ergonomicCons:- Can be a little confusing to figure out at first due to no instructions being shipped (at least with mine)- Can sometimes be awkward and difficult to use if the bike isn't perfectly stable- Build quality definitely feels like the usable life is only going to be around 50-70 full tires- I have to baby it a little bit to keep it from overheating and melting the cylinder sealsOverall, totally happy with it considering what I paid. It's a great thing to have around and does its job well, just be easy with it and it will perform longer and better. It's all plastic and it's not exactly what I'd call robust, but it's definitely not a piece of junk.4.7.24 - UpdateHad this thing and have used it to fill well over 100 full tires, the logos have almost worn off the handle by now and it still feels just as sturdy as the day I got it. This pump was well designed and well made, I recommend it highly.2.14.25 - UpdateI still have this thing, and it still works. The folding handle snapped off so I screwed a piece of wood onto it, and the thing still is going strong. I use it to fill up my tires at least once or twice a week. Whoever designed this definitely chose the right materials for the internals.

Compact, convenient to use, has great pressure and for the price the quality is great. We keep it in the bottle of our BOB stroller and my husband is an avid mt. biker and has one on his bike as well, so the size and design of it is very multi-functional. Always comes in handy!
