Apollo I Ultra Compact Mini Bike Pump with High Volume / High Pressure Switch

I paid full price for this item. I did NOT receive a discount in exchange for a review.I had a problem with the pump leaking at the locking lever, but was able to pull it apart with needle-nose pliers and remove a sliver of plastic flashing that was stuck on the O-ring in the back. Customer service was very helpful and receptive with return/exchange options...but, turns out, that fixed the problem.The pump itself works as intended. It is surprisingly light and small...but with the high volume setting, I was able to add air to a tubeless 26" mtb tire. I have not tried pumping a Presta valve with it yet, but it locks on to Schraeder fine.I wouldn't expect it to be able to re-seat a completely deflated tubeless tire...but, in a pinch, it should work just fine to add some air in an emergency. The head doesn't seem overly fragile and build quality is good. Operation is smooth. The switch on the bottom is a little looser than I would like, but serviceable. I suggest making sure all the plastic pieces are screwed hand-tight onto the aluminum barrel and maybe lubing up the rubber seals with silicone grease if you have some on hand.For me, this pump passes muster and will be stored with my tubeless tire plug/patch kits and extra Stan's juice in a triangle bike bag.

Does not inflate well, at all. Tough to attach to valve stem and doesn't seem to fully seal while inflating. I attempted to fill bicycle tires from 15 to 40 psi and took about 30 minutes to get one tire done. While inflating there was a hiss as if only some air was making it into the tire. High volume and high pressure settings yielded the same very slow results. Due to the extreme time, the pump also got extremely hot. The aluminum is very slick and difficult to maintain a good grip while pumping. I am returning the item and will try one with a small handle on the back end, has a short hose, and has better grip. It is very compact and light, which was nice, but would not serve as the only pump or if the tire has a quick leak while out.

Small and efficient. However, you need to push really hard to get the valve to open and fear I might damage my tube - a rubberized extension would have been better.I tried hard and getting more than 35-40PSI was difficult even in high pressure mode for a road bike needing 100PSI. So the high pressure mode is a mixed bag.I am not a muscle man or wrestler but nor are mist cyclists!However, that pressure is more than enough to get you started again till you find a larger pump.thinking of 3 stars but 4 does it more justice due to its small size.

This little gem works better than all the other Bike Pumps I detail with.It's small enough that it doesn't take up a lot space in the back pack when riding, and pumps up the tire in a reasonable time frame.

This pump is a great deal. The price is right, and it works reliably. I like the fact that there is a cap to keep road dust out of the head.

Compact, fits inside a small under-saddle pouch. Works well in a pinch.

Fits in an under-the-seat bag, how cool is that?

Did not stay on while trying to pump.
