The Prime (KS3) Freestanding Kewlus Kit is ideal for taking it with you on trips because it includes a set of Platform Paddles for a quick and easy assembly. It can be set up for both adults and children, providing excellent boxing reflex training for all.
Kit Suitability
This kit is best suited for those who would like to get started training with a cobra bag with maximum setup ease and without the need to make a DIY base. It's also ideal for travel as the kit comes apart and fits into a small box (19 x 7 x 7 inches). For more advanced performance I recommend the O3 Kit (or the KS3 Core Kit with a DIY base).
Performance Note: To get the best performance from the cobra bag, please fill the sandbags to the very top and ideally with wet sand (use a garbage bag as a liner inside each bag). To enhance the performance consider adding a second set of sandbags (optional) - this will add extra rigidity to the mast. You can also slide an Olympic Sleeve (optional) onto the mast and one or two of your own Olympic weight plates. If you need absolute maximum performance and extra height, consider making a DIY base or purchase the O₃ Kit which comes with the OctaBase - a very rigid base similar to a DIY base.
ATTENTION: It is critical to assemble the target ball and the Paddles correctly. Please ensure you read the instructions fully before use. Failure to assemble correctly may void your warranty.
What's Included:
- The Prime (KS3) Spring: Third generation spring made from the unique formulation of metals for the ultimate performance and longevity. No other spring comes even close.
- Genuine Leather Prime Target Ball: Genuine leather target ball designed for ultimate performance and durability. It's the perfect balance between speed and power.
- Target Ball Adapter: Extendable length for increased reach, designed and engineered to allow flexibility at the rim for cupping the ball while maintaining top section rigidity and rebound speed. The Adapter and Kewlus targets have been designed in unison to fit perfectly together for optimum performance.
- 2 x Click Bars: Lightweight, rust-free aluminium bars which can be used in both the bottom section (below the spring) for overall height adjustment and top section (above the spring) for adjusting the range of movement of the bag.
- Alloy Mast: Made for the general use from lightweight alloy that will not rust.
- Base Connector: Versatile base connector made from composite fibre for the ultimate strength and rigidity is unlike most of the common water filled based where rigidity is lost due to the non-fibre plastic that is used.
- Pair of Sandbags: Designed for stability when filled with sand, especially if using wet sand (make sure to use a garbage bag as a liner).
- Platform Paddles: Super strong using composite fibre materials, they are ideal for travel as they fully come apart, allowing the whole kit to be packed into a very small box.
Height Range:
4'8" to 5'7" (143 cm to 171 cm). Convertible to a shorter form for children or alternative mounting.
Optional Add-Ons:
- Additional Pair of Kewlus Sandbags (V2): For extra weight and stability.
- Olympic Weight Plate Sleeve: Allows the use of one or two Olympic weight plates for added stability.
- Red Bar: Increases the speed of the cobra bag.
- Cobra Bag Replacement Bladder: Backup replacement bladder for future use.

I did an extensive research before pulling the plug. This one is superior in every aspect. Very well built. Sturdy and stable ( with the sand and couple 45 plates ) unshakable. Incredibly easy to put together.
Now, the thing we use it for, the lunch and the bounce, it’s amazing. Great feedback and bounce.
I know as a consumer we feel safe knowing things that can be returned are safer but with this you wouldn’t want to return it even if that was an option.
Let me wrap it’s up by the customer service, you are not going to get a better service. Fast communication with care and genuine customer support.
I’ll buy it over and over if I have to.
Worth the investment.
Don’t hesitate to pull the plug. Everything about it is top notch.
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! I had a leak in one of the bladders so I reached out to customer service, and a replacement was sent out that day, no questions asked. When you have an amazing product, and amazing customer service, you're bound to build a huge business, and I will always support this company due to the way they have treated me. 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!
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.
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
