Bike Pump by Geared2U - Mini, Compact & Portable - for Road, Mountain Or BMX Bicycles - Presta & Schrader Valve Compatible - Premium CNC Aluminum - Extremely Lightweight

Th Geared2U mini bike pump is a such a great find. The pump is small and effective and perfect for bikes, balls, or stroller wheels that need to be pumped. The best feature about this pump is its size. It's about 7 inches long and maybe half inch wide. It comes in a good color (black/silver) and made out of aluminum so its nice and light. The bike pump has a good air flow push for a small size. According to the box the capacity for air is "7bar/100 psi). The pump comes with a bike attachment so that it clips to practically any part of your bike since its small in size and one added bonus feature is it comes with a air needle (which I liked) so you can use to pump air into your soccer,football, or basketball (or any other ball for that matter that needs a needle). Oh forgot to mention the mini bike pump is very light at 93g according to the box. If you need a simple, small, multi-purpose, or bike pump then I recommend you getting this one. Cheers.

Great pump. Scratch that, good pump. Compact, light, mounts to the frame. And Geared2U stands by their product. My mount snapped in half after I hit a bit of a pot hole in the road. The pump fell to the road. I was able to grab it, but the plastic mount was no good. I emailed Geared2U. All I wanted was a replacement mount. They sent out a whole new pump and mount...expedited shipping and free of charge!Very cool. Now I still need another mount and I'll put the other one on my wife's bike.So, why good, but not great? Well, I've fixed 4 flats with this pump. It does the job and gets me home, but after about 5 minutes of pumping, my tire is still only at about 65 psi. I ride 700 x 25 road tires. I am thankful to be able to limp home, but still I would like to be able to finish the ride. I imagine this will work great for mountain bike tires, just not for road tires that require 100 psi.

There are already plenty of positive reviews on this pump, but there a few things I would like to add. The first thing I would like to talk about is the quality; it really feels like a quality product. It is solid and doesn’t feel at all like it would fall apart.There are a few downfalls of this pump, though. The first downside to this pump; is the lack of air per pump. This is to be expected with a smaller pump, but it is still something to note. I had to inflate 2 bike tires from 20psi to 50psi, and it took me like 15 minutes and my arms were burning by the end. It takes quite a bit of force to pump the air once you’re closer to 40-50psi. Also the pump got so warm, I think you could have cooked eggs on it.The other note I would like to make is that the instructions are very confusing, the pictures don’t make sense with the included parts, and there is really no written directions to follow. I spent the first 20 minutes before I started pumping, just figuring out how to set it up to pump a bike tire. Turns out, it comes in the right setup to pump a tire; I just wasn’t ramming it down onto the valve hard enough. You should only have to change the setup if you plan to use the needle.I would like to add 1 more thing. Most bike pumps have a locking lever, but sometimes up is locked, sometimes down is locked. For this specific pump, the lever locks in the up position. So the lever should be down as you’re seating the pump onto the valve and then lift the lever up to lock it.I would buy this again, as it is so compact, convenient, and the highest quality small pump I have come across.

I'm not sure if I got a complete lemon, but am feeling burned by the positive reviews on this pump. Sure, it is cute and appeared decent until I actually tried to use it to pump up two Presta-valved bike tires. First, the directions on reversing the valve from Schrader to Presta are micro-printed and actually wrong - they show one piece being rotated when in reality there are two. Once converted, attaching it over the valve was extremely difficult. The lever appeared to make no difference in tightness on the valve - it leaked unless placed in just the right position. After pumping to the point my arms were exhausted, the tire was only about 1/3 inflated. At that point I tried to remove it and try pumping up a different tire - but no, the thing was stuck fast on the valve. I struggled with it and finally got it off, hitting the spokes in the process. I did try it on another tire, and got the same results - leaking, slow pumping, and stuck. I gave it to a friend to try and after they tried it they threw it in the trash for me.

This bike pump feels cheap but works well and fits just about anywhere you need it to. It should have come with adaptors for different stems but you can easily find the on line or at a local bike shop. The three stars is due to not knowing how it will hold up over time and an update will be posted if needed.
