Not difficult at all. I have used it on my adult bike and also my sons, goes on as it should without any hassle and comes off easily too, no struggle.

How easy and smooth it is to put on and remove the air valve is an indicator of the quality of the air pump. It should not be an issue if the valve is made properly. This is why I spent a little more money and purchased the Serfas TCPG Bicycle Floor Pump. The experience I have had with cheaper bicycle pumps is similar to yours. The Serfas pump works very well and smoothly and easily goes on and comes off the air valve. I've had no problems with it and highly recommend it.

Putting on the first time took a few tries...it takes a bit more force than most others I've used and seems backwards to me for some reason. I think that I'm used to using my DC powered pump which has a lever that you push down (from vertical inline w/valve to 90 deg. perpendicular w/valve) - this one starts in the down pos. and is flipped upward to inline position to engage. However, once it's on it stays put during pumping w/no issues and the back pressure is enough that just flipping the lever is enough to pop it right off. It does take a fair bit of effort though to get it on there and fully engaged. Hope that helps.

The opening is of a reasonable size so it's easy to get started. You do need to push firmly to get it deep enough to lock well but it's not excessive. Same goes for removal; you'll need a firm tug but it's not so much that you'll bang your hand on somehing when it disengages.

I haven't really had any problems on the presta valves. It seems about right to easily use on a standard valve. Some wiggle room, but not so much so that it won't grip and seal for filling.

Same thing with me but I put a little air in it- put it inside the tires-put them on the rims and then pumped them up to correct pressure and they worked great. Try it- I didn't think they were the right size but they have been on 2 months with no problems.

As the others have said, it's a bite valve that has to be squeezed (quite vigorously) at the bottom to inflate or let the air out. I'm sure there's a more difficult valve out there... I just don't know where it is!

you need to use a air mattress pump not a bicycle pump. The valves are the same as on most air mattresses.

I don't know the answer to your question. I will tell you that this product would not come off when I needed to place air in the tire. I had to spend over $100 per tire to have all the valves replaced.

In the center of the valve where you inflate the tube, there should be a little pin. If you use a sturdy piece of plastic, or a tool used for removing tire from bikes to change out bike tubes, you can empty the air from the tube quite easily. Just make sure to hold the valve steady so that you don't cause any damage to the tube.

You need to squeeze the valve while you blow into it. It is a bit hard to do at first, but does loosen up after you use it a bit. Hope that helps!

Hi! I love these and they're easy to use! Hold the bottle part down with one hand firmly over the neck of he bottle, and pull the vacuum part up several times until the a great deal of the air has been sucked out of the bottle. It'll get harder and harder to pump with each pull. To remove, just pull the entire thing off. Hope this helps!

That's a good question. Normally the orange lock on the back is supoused to keep engaged the pump to the bike but I was not able to do it. The only solution that I found was to hold it with one hand against the wheel and pump air with the other.

Yes you can, I have same tube on my bike. And it is more trouble then it is worth, tires are hard to fill up. I hear people say all the time, fill it up at the gas station, buy a bike pump. I've tried, and I already have a pump. Neither work, I have to take it to walmart cause they have HIGH COMPRESSION air, or a bike shop. The first time I filled it up with air was easy, now it's a headache

yes the small one has a smaller air chamber and takes a significant amount of pumping and effort to get the tire to the proper psi. the size is perfect for carrying as a just in case pump. I would not use this as my primary pump unless your tires are very good at holding air. the size of the pump is amazingly small and very light just the perfect pump to carry in a backpack or attach to a bike. Just don't expect it to be easy or fast when pumping up your tire is all.

Hello. You simply completely remove the bottle cap, place the pump onto the bottle, then screw it on. I hope this helps.

For me it is easier to pump the tire with an angled valve as the spokes on the wheel has a tendency to get in the way if it is a regular straight version. It really depends on your pump, but the angled valve gives you some flexibility. Hope that helps.

Me neither....until now, it is a large valve about an inch in diameter(not like a car/bike tube valve). search amazon for an airhead pump. I would have gotten from amazon but it would not have arrived in time. I got one from Dicks, it was about the same price as amazon.

My mom blew it up originally because we couldn't find our air pump. It didn't take her long. I also use a bike pump when necessary.

You need to find the correct air connection to fit your air compressor line, there are several different types. No you can not use a bicycle pump, the make a manual version of this product if you do not have an air compressor. I really like mine.

I had no problem putting air to the tires by using a regular hand pump. Perhaps you might want to check the pump? Make sure the pump head is inserted fully to the tire's valve
