Portland Design WorksThe Ninja Pump & CO2 Inflator

Easy to control a CO2 cartridge release and great for that purpose. As a pump, it took near 400 strokes to limp home on a 25mm at 90psi so treat it as your CO2 emergency backup. Small enough to fit in a seat bag or in a jersey pocket. Like most PDW stuff, it's nicely made. Be aware the presta adapter extends with a reverse thread.

Chef Alton Brown is famously known for his dislike of single-function kitchen devices. The same guidance applies to our biking rescue kits! While a multipurpose device often comes with limitations vs. its single use cousins, the space and weight savings on our steeds is a welcome compromise. This pump is lightweight, compact and eliminates the need for a separate CO2 valve as it’s built right into the pump. Some valves do not come with an on/off function- so as soon as the CO2 cartridge is punctured it empties itself. Not so with this little guy. If you have CO2 left, you can close it off and thrown the pump in your pocket in case you need a little boost down the trail. NOTE: obviously it’s more bulky if you do that and when you remove the cartridge it will release all its air.

Some critics here ding this mini-pump for how many strokes it takes to inflate your tire. Well of course, that's the drawback to a MINI pump! I use this primarily as a CO2 inflator. The hand-pump I find useful mostly for partially inflating my punctured tube to find where the leak is, and for testing my patching job to ensure it's leakproof. But to really inflate the tire once it's mounted back on the wheel, that's where the CO2 cartridge is necessary. I would highly recommend planning to use it in this manner, not as a pure hand-pump inflator.Note I use Schrader valves, not Presta. I have had no trouble using this with Schrader valves, and cannot comment on the criticisms here of using this pump with with Presta. But if you also use Schrader valves with it, I doubt you will have issues.Meanwhie, it's a tiny pump, and the included mount tucks it behind and to the side of a water bottle cage where it's barely noticeable, but easily accessible when you need it.I do wish they included a CO2 cartridge sleeve to insulate your fingers from a freezing-cold CO2 cartridge. Most CO2 inflators come with one, and I know PDW makes a nice leather one, so it seems an inexcusible oversight not to include one with this device.I have not experienced the valve lock-up some have described using this as a CO2 inflator. It might be related to the cartridge brand. I exclusively use Pro Bike Tools' 25g cartridges with this and have had no difficulty after about a dozen uses between two of these pumps on two bikes.

or be screwed. i had to use a wrench to get the presta valve open. it somehow fused shut again and it was impossible to open with my bare hands. I have had to use this pump on the road twice recently and it works fine for an emergency only if you can get the valve open. Luckily i had a blowout near a Tuffy, and they separated the valve for a second time...

I pumped up 2 near-dead flat tires in less than 5 minutes with this thing. Secures to the tire well and pumps with ease. Just be sure to brace one finger on the opposite end and not try to grab it at all. I got a little overzealous and pinched the ever-living @&$# out of my finger; a valuable lesson learned. Definitely a buy, though.

I had to use pliers to get the presta valve extension out but not that big a deal. I used it once and like it. Then the second time I needed it the valve was totally frozen. Lost 2 CO2's and never got it to work again. Of course it's now 2 weeks past it's return window. This thing is junk.

I have the tendency to over analyze certain parts that I am looking for and a portable pump for my bike was no exception. There are a ton of pumps out there to choose from ranging from cheap-o plastic junk to really nice and expensive ones. Then there are the CO2 inflators which are usually small and simple, but require you to carry CO2 cartridges and if you run out of those, you’re stuck. I like to plan for the worst and hope for the best, so I would rather spend more time on the side of the road pumping a flat tire instead of relying solely on a one shot deal. With this pump from PDW, you can get the best of both worlds, which appealed to me, so I gave it a shot.It weighs 72 grams and the construction of it is very nice and the pump does not feel flimsy at all, even while pumping, there is no flex. With a deflated road bike tire, it took me 1:37 to get the tire firm enough to the touch to be able to ride home safely. I tried counting the pumps, but got lost after 158 or so pumps. What can I say, I’m not good at counting fast, my bad. If I had to guess, it would easily be over 200 pumps, but they go quick. If you plan on using this as your only pump for any bike, get the taste out of your mouth right now. It is way too impractical and moves very little air and high pressures are not easy to do. After 1:37, I checked with my Birzman gauge and was surprised to see I was only at 65 psi… Guess my “sidewall squeeze test” isn’t very accurate, haha. In my opinion, this pump’s only purpose is to get your bike rideable again so you can get home. The CO2 inflation is super easy and went just as planned, so no issues at all with that. Pumping it up to 100 psi took forever and what do you know, I lost count again, apparently me no count good. When you get to the higher pressures, it gets pretty hard to pump.My biggest gripe about the pump was how hard the Presta attachment was to get loose the first time. Seriously man, I’m not some weak little human being that can’t open pickle jars and stuff, I’m the one that opens them for those kind of people. I thought I was going to break the pump in half and throw it across the road, I was so mad. I had to use some pliers to get it loose the first time, which no one carries on their bike when they’re riding, so you would be screwed if you didn’t do it before you need it. For this, I knocked a star off. Other than that, it is a great pump and will get you home if you need a pump. It came with a small mount that goes under a bottle cage, but I don’t use it and instead put it in my SpeedSleev Saddle bag. Anyways, I hope this review helps someone and if you do get it, make sure you pull the Presta valve attachment out before you actually need it, for real.

I have used co2 inflators in the past, but always carried a hand pump just in case i needed a back up. I thought this combo pump/inflator was an elegant solution.At first i only used the hand pump and the performance did not blow me away or anything. It's a lot of effort to get up to a decent psi, but this is for emergencies and for that it would do the job. The trouble started when i ran over a construction staple on my way to work and opted to use the co2 inflator for the first time. I could not get the valve to open no matter how hard i tried, had to pump by hand and was late for work. Even when i got home i still could not open the valve, not even with vice grips which pretty much mangled the nob anyways. Unfortunately this all happened on the last eligible day for a return and i don't have a way to print the return label and mail it out by tomorrow. I wouldn't recommend this pump and as this is my first pdw product, i will probably steer clear in the future.

This is well-made and looks good. As a CO2 pump, this works very well. As an emergency pump, it's okay, but it's too small to be anything other than a 'get you home' pump. The bracket holds the pump very securely. One downside is that the openings for the CO2 cartridge and valve aren't covered, so they're liable to getting water and muck in them.

I tested the CO2 cart and it worked great. I will carry 2 carts. I would not want to pump 80 psi by hand. Storage under my water bottle cage works well. Could not store it under the holder for my FoldyLock.
