I absolutely LOVE my Kewlus bag. I get an amazing working, I'm dripping sweat after just 10 minutes punching it, and i have a blast! Outside of the set up being awesome, the customer service is Outstanding!

It's so refreshing to have a company that actually cares about their clientele. If you're looking for a great workout thats fun and helps improve you ability to hit a moving targer, INVEST IN THIS SYSTEM TODAY!! Thanks Kewlus team, y'all truly do rock!
Highly recommend grabbing yourself one of these ks3 cobra bags!
Pros: Very high quality material.
fast and responsive.
Easy and affordable to upgrade with its modular abilities.
Keeps up with other professionally used bags such as fierce. (Sorry if naming other brands is not ok).
Great for beginners as you can adjust the speed with a simple click until you catch on!
Cons:
The only real downside which is fixable and not a big deal is the squeak, because all the metal bars click together, if you hit it on edge it turns the bar slightly causing a squeak. (Easily fixed with a tiny bit of grease on the bars)
Recommend grabbing yourself the red bar with your order for later use as it’s not very expensive and will save you delivery fee later when you want more speed!
The owner Reedy is super helpful and has lots of helpful videos which makes me support this brand even more!
I had a problem with my adapter. I contacted Kewlus and they more than made things right. I cant believe customer service like this still exists.
Glad I purchased this bag after going back and forward trying to decide which to purchase on the internet (so many these days to choose from happy I chose Kewlus).
Why is this bag so great and how does it compare to others?
Kewlus bag is modular as stated but moving it into the corner out of the way is very convenient when you use the kewlus sand bags vs. a competitor cobra bag that uses a fillable base (for me it's easier to move some sand bags instead of a base of water filled or sand filled container where it's purpose is to not move).
The leather bag is very well made (smells great when you remove it from the shipping packaging) and it's built to last, no cracking after owning it for 6 months now, plus is it's replaceable! There are other bags in the same price range do not have a bladder and don't have replacement bags available. It's also a bit lighter in terms of weight so it doesn't fling around on the base that holds the bag unlike other cobra bags. I've noticed I haven't had to pump it as often as a result compared to a competitor cobra bag at the same price range.
Lastly, Kewlus' customer service is also five stars. Reedy was quick to respond to my questions and kind enough to send me a replacement part when I broke a piece (it could have been my fault but Reedy sent me a confirmation of a replacement piece right away via email with shipping info.)
Overall, I am very happy with my cobra bag and can't wait to see what else Reedy has in store for it.
Hi! I’ve practiced martial arts starting at age 7 and a boxing beginner. The O3 Kewlus Kit makes striking and punching a blast to train. It’s by far the most fun training gear I've ever used and so versatile that I can isolate practicing upper cuts, crosses, jabs and combos. I’ve been using it for kicks too and it’s holding up great. Being able to vary the reflex speed comes in handy on implementing new types of strikes gradually and keeps it fun!
I did some online research and almost purchased the Grodex Cobra Bag. I'm so glad I found the Kewlus Cobra Bag instead. I can't recommend the Kewlus Cobra Bag enough. The quality is top notch and very sturdy despite the modular design. I was expecting the product to be flimsy, but I couldn't be more wrong. I have practiced martial arts for over 10 years and can hit a bag with decent power. The Kewlus bag held up fantastic so far and rebounded quickly with the heavy duty spring. The Customer service at Kewlus is unparalleled! Reedy was very responsive to my inquiries even post sales. I won't hesitate to buy Kewlus products in the future for all the reasons mentioned. Awesome product! Thank you.
Absolutely brilliant system , my son loves it and the ease of setting up where you want to use, and to be able to pack up and put away. Top product , highly recommend to aspiring boxers, well done Reedy
Incredible product, if you follow all the steps on his website and YouTube demonstrations, you will succeed in making your DIY cobra bag. Thank you Reedy and team for sharing your love and creativity with the boxing community!
The Air-Free bag is a great add-on for developing a stronger punch. It's a little slower and heavier to hit. Feels more like hitting something solid and good for developing the hands and arms. Due to my work and schedule I use not only boxing gloves, sometimes MMA gloves and even my bare fists a few minutes here and there as I pass by the Reflex Cobra Bag. My home and work place are the same space.
Hey Reedy, Yes, so glad I sprung for the KS2 Spring and definitely the added KS2 Spring Caps.
Made a tremendous difference from when I started with just the 3/4 inch PVC pipe alone. That was NOT working for me. The solo PVC had Very little spring and continuous bounce for sure.
Will try to send pics of final
Product. Going to buy a Coupling to add 4 inches now and have really fast Cobra bag and one slower bag without changing height OR compromising the Spring longevity.
Did get whacked in face a few times, but that's the learning process.
Thanks for ALL your videos that helped tremendously with the build. And of course a "shout out" to "cssquaredboxing" videos for all his videos and input where he always mentions Kewlus. Com
Incredibly well made, very sturdy and amazing customer service.
The KS3 spring is just so incredible fast and has a really great rebound while still not missing out on reach, so it's perfect to work on my Philly shell.
The fact that the whole bag is modular makes it even better. I'm pretty tall, so I might replace the lower click mast with a galvanised pipe to use the shortest/fastest setting of the bag.
It's just a quality product and you can't anything better for this price, plus the customer service by Reedy is top notch.
Love it. The KS3 spring makes the bag faster, easier to adjust height and overall more fun to hit.
I love this bag. It really trains my eye hand coordination. I also think the quality is very high as well. I definitely recommend.
Overall, Spring reflex action is good but DIY build can be improved. Some of this could be be me but want to share issues I ran into during build.
1) Finding a 3/4 & 1 Inch metal pipe that fit between each other is tough. I tried HD, Lowes, Menards, etc and didn't have success. I spent 3-4 hours using hammer and sanding tools/brushes to make things bit more manageable.
2) Butterfly clamps are good but need something more sturdier. Jabs are great but if you plan to mix Jab with uppercuts you might send the pvc pipe flying upwards. I have to hold back power on uppercuts to overcome this issue. My thinking is that better or more clamps are required to overcome this issue.
3) I have no vibration or sound when I use the bag which is great. If you pay close attention to the build it should be mostly sturdy.
4) I did not build circular base and choose rectangular shape so I could put two 55 lbs plates (total 110 lbs) on the base. I attached flange to a rectangular shape pressure treated wooden board (approx 1.5 inch thick and 10 inch by 40 inch). I am realizing circular base would be better. I will rethink this later.
5) Note, with amount of time spent to get the metal pipes to fit in one another and $'s spent (Metal Pipes, pvc pipe, flange, pvc connector, butterfly clamps, bag, spring, duct tape, funnel, screws, and wooden board), I would highly recommend just buying the whole kit vs spring. Now, if you have some of these things at home already, then you may find it beneficial to buy spring and build. This was not the case for me.
Lastly, let me just point out that the bag is so much fun. I have gotten smacked in my face a few times but still enjoy very much. Thank you
I have taught martial arts/fitness classes for 40 years and have the ringside cobra bag andI am an equipment junkiie that has purchased lots of training equipment through the years. I found the ringside bag so slow but the Kewlus bag is far above my expectations. Thank you for listening tp buyers and creating a wonderful training tool. My wife uses it as well.
The Red Bar definitely gives more speed and changes the training. It's also easy and fast with a simple swap out. I like to switch things up and change the feel and response regularly. The Air-Free bag is also excellent for that. Although not as fast as the pump up bag it definitely has a harder, more solid feel providing greater resistance to the punch.
This is the only modular Cobra bag. VERY quick and easy to set up, extremely fast spring and quality parts. I love this product, and the service and communication from Kewlus is exceptional. I highly recommend this product! I've tried several other cobra bags, this has been the best of the bunch.
This is the best unit I’ve used I’ve tried 4 different brands until finally finding the one that I’m happy with I run a boxing gym about 40 fighters hit this daily and it is very durable and these guys have great customer support I’ll update a video soon of us hitting it
Thank you Kenny for your review!
Most used piece of equipment in my home gym everyone who sees it wants to use it . Quality made to take any punch Iv'e seen so far . This is a must have for someone getting into cadio workouts make exercising fun .
I was looking around for a cobra bag that would not break the bank and the kewlus kit is probably the best option. From the youtube videos that I have watched of other cobra bags, it seems there are none that even come close. I have been enjoying it and so far have no complaints.
My Fierce cobra bag failed. Seam split. Could not get replacement from Fierce. Sold out. No availability date. No response from customer service. Found perfect substitute with Kewlus cobra bag. Perfect fit. Better quality. Extra bladder included. Will never buy Fierce brand again. Big mistake buying Fierce in first place.
I ordered the Kewlus Cobra Bag Spring (KS3) as soon as it came out. Upgraded from the KS2 and man is it a huge upgrade! Since then I have put hundreds of rounds on the cobra bag and it has held up perfect! one thing I did notice was the stability of the mast click bar a little wobbly. Luckily I followed Reedy's YouTube video and built a second deck. I put some Olympic weights on top of my sand bags then I wrapped some duct tape around the click mast to lock it into the Olympic weights and it is a huge improvement to the stability! The second deck was all it needed it works perfect! If yall wanna know how its done look at Reedy's YouTube page he posts a lot of updates on there and upgrades for the cobra bag kit! Hopefully this review helps!
5 stars!
