VeloChampion Mini Bike Pump with Frame Mount | Portable Compact Alloy Bicycle Pump with Frame Mount | Presta, Schrader & Dunlop Valves | for Road, Mountain, E-Bike

The pump is so easy to use. I've been using these pumps for 5 years. Seems fairly durable. It's plastic so I don't have to worry about corrosion or it getting exposed in the rain. I keep it in a little bag with my bicycle. It's easy to pump with it. I've had several flat tires, and this has come handy in those emergencies. I'm more concerned about the size & weight of this since it's always with my cycle. It's important to me that the size is small. With it's blowing capacity, I just pump around 50-100 times, and I have enough pressure in my tires to at least get myself home to pump further.

It's Small! It's light weight! It will give you a workout! So far I used it to fill some tires on my fixie it has the presta valves and it did the job. The pump is extremely small and doesn't put a lot of air into the tire with each pump but it does work! It's cheap and really small comes with a holder for the bike. Great to take on the go!

The pump is small and light, but a little flimsy.

great pump,but doesn't give much air so youll have to pump longer. definitely worth the money,but use mostly as a back up pump if you are lazy. or use it as a fan when youre hot hehe but in all seriousness it is a great pump,small as hell. you could fit this anywhere including your pocket,but if youre one of those skin jeans wearers then you wont be able to get it back out unless you pull your pants off or cut a hole in it. youre thinking "if its that small it cant pump much air.". maybe 6 minutes tops from flat. but most dont let their tires get flat before they pump it. the strap as far as ive experimented with it is ABSOLUTELY useless. doesnt fit around my bike frame,maybe around the handle bar tho. even so it probably would fall out. so just get some duct tape like we do to fix everything,and use it to fix the straps.

Excellent little pump! So light and small that you would think it can't do much, but it CAN. I have it attached to my road bike and it has saved me twice when I've been out many, many miles away from home. After fixing my flat, I pulled this little thing out and It easily pumped my tires back up to where they were pretty hard (probably around 90psi). Using it IS tricky because of its size--not much to hold on to to get strong pumping action. To solve that, I placed my wheel on its side on the ground, folded the old flat tube into a block and placed it between the head of the pump and the ground--problem solved; I could pump as hard as I wanted because the force was being applied against the ground. Used the presta side--I have not used the schrader side.

Light, rugged pump. Mounts very securely next to your water bottle, using the same 2 screws and therefore taking up no room. The clever Velcro strap ensures that it cannot depart your bike accidentally. Another reviewer stated that the pump slides open while mounted on the bike. This is user error. The little hole in the bottom half of the pump (visible in the main picture) lines up perfectly with a pin in the holder, making it impossible for it to slide open once mounted correctly. The directions do not mention this, but just a tiny bit of mechanical aptitude makes it obvious how it is intended to work. This also works very well on Schrader or Presta valves. As shipped, it fits the common Schrader valve. But if you unscrew the light gray piece at the valve end, you'll see two little black plastic pieces inside. BE CAREFUL NOT TO LOSE THEM, especially on the trail. By flipping both pieces around and screwing the light gray bit back in place, you will find that it is a perfect Presta valve pump. The directions do mention this, but they consist of a very small single piece of paper, and are easy to discard without noticing. I wouldn't try to inflate a tire completely with this pump, as it would take a long time. What it is intended for is to partially inflate the inner tube, allowing proper twist free alignment underneath the tire, before using another method (my choice is CO2) to completely inflate the tube to spec. I suppose you could (in a pinch, no pun intended) use just this pump to inflate the tire to 35 PSI or so from flat, but I'm just too lazy and impatient to even attempt that unless I have no choice.

I buy this from my brother. He needs it. I tried it first in my roommate bike and it’s worked great. I recommend it.

The pump is lightweight and easy to use. However, when pumping up my tires on a hybrid bike, the part that connects to the tire stem doesn't seem to hold under high pressure. The connector on from the pump to the stem screws into the pump and under what seems to be moderate pressure (50 psi according to my guage) the screw in connector gets pushed through the threads and air starts leaking out of the tire. I can't seem to get my tires above about 50-55 psi despite the claim that the product can pump up to 100 psi. It'd be good to keep on you when riding in case you need to get enough pressure to get from point A to point B but the one I received isn't serviceable as a permanent tool to maintain tire pressure.
