The Kewlus Modular Cobra Bag is the world's first modular cobra bag capable of customisationsadd-ons, upgrades and DIY integrations. The KS2 Kewlus Modular Core Kit is ideal for those who want to try out cobra bag training at minimal cost and are able to either bolt it down to the floor (like a deck) or make a DIY baseboard by simply gluing together two or more MDF or chipwood boards. The KS2 Spring can always be upgraded to the KS3 at a later stage as you progress and want more speed and power.

ATTENTION: It is critical to assemble the ball and adapter correctly. Please ensure you read the instructions fully before use. Failure to assemble correctly may void your warranty.

What's Included in the KS2 Kewlus Core Kit

The KS2 Cobra Bag Core Kit includes the following from the top:

  • Max Speed SF Cobra Bag Ball, designed for speed and a clean look. Being lightweight, it makes this ball the ideal companion to the KS2 Spring;
  • Kewlus Cobra Ball Adapter (V2), designed to be used with most speed balls but is the perfect match for the Kewlus Cobra Ball. One unique feature that's not found on other cobra bags is it allows the user to extend the length of the top section, thus increasing the reach of the cobra bag. In the KS2 Kit it is mounted onto the Red Bar.
  • Red Bar - designed to make up the top part of the cobra bag, its light weight allows for faster movement of the bag. It goes into the top of the KS2 Spring.
  • Kewlus Spring End Covers (set of 2) - these are rubber covers designed to screw onto the ends of the KS2 Spring. They are designed to allow the Red Bar and the Click Bar to click into the Spring.
  • KS2 Spring - 2nd generation Kewlus spring that fits onto the Click Bar and is also compatible with 3/4 inch pipes for DIY setups. The Red Bar and the Max Speed ball make up the ideal combination for the top section of the cobra bag when using this spring. 
  • Click Bar - made from light, yet strong aluminium which will not rust, it is designed to click into the Mast to make up the bottom section of the KS2 cobra bag.
  • Kewlus Mast - designed to click into the Base Connector for quick and easy removal and storage of the cobra bag. Made out of aluminium it will never rust. The bottom Click Bar slips into this mast and clicks in place at the desired height, giving you height adjustment suitable for both kids as young as 8 and adults as tall as 6 foot.
  • Kewlus Base Connector - super strong, minimalistic base made from composite fibre. It comes with a stainless steel clamp for the collar to lock the mast in place for the ultimate rigidity - please ensure the steel clamp is tight around the collar before using the cobra bag - see picture.
  • Please note that the Core kit does not come with a base. To make a base, please refer to https://kewlus.com/blogs/diy/how-to-make-baseboard-cobra-bag

Height Range

The height range of the cobra bag is roughly 4'1 (124 cm) - 5'11 (150 cm) from the floor to the top of the ball. Ideally you want the top of the ball to be at about chin level when you're standing fully upright in front of it.

This range can be extended for taller people by making a taller base - simply glue together more boards to make up the height. Check out the Advanced Setup page and video to see how I made one using 8 MDF boards: https://kewlus.com/blogs/diy/advanced-cobra-bag-setup

What a great bag!

Reedy has created a very impressive, yet simple cobra bag (at a decent price). I ordered the PVC pipe kit and found it to be incredibly fast! I'm really enjoying it so far. Leather bag itself feels great and all the parts seem well made. Everything just clicks in, like Reedy says it does. Love it so much I ordered the spring to be able to switch between the spring and the PVC bag(s). Great product(s).
At one point, I had to email Reedy with a question and he quickly responded. Customer service, also five stars!

Good but made adjustments

Overall I’m extremely satisfied with the quality of construction. Everything is built to withstand a beating EXCEPT the tiny screws that hold the multi base to the wood board. A hard punch ripped the tiny screws out of the wood. My solution was to drill the holes of the multi base to be wider, and install bolts through the board and multi base to ensure it will never come loose again. And with this, it’s actually able to be uninstalled from the wood board for even tighter storage/transport if desired.
Otherwise it feels amazing and I’m definitely getting my warm ups in before kickboxing classes.

Thank you for the review and the feedback! Awesome - you did the right thing to use larger screws/bolts. The screws that I included are really meant for the Platform Paddles which plug into the Multi Base and only require minimum tightening. If using with a custom baseboard then I totally recommend getting thicker and possibly longer screws (or even bolts) to match the thickness of your baseboard and base combined.

Mostly good with some hiccups

I've owned the KEWLUS cobra bag for about 6 months now. It's actually a great product for the price. I would say other comparable products will run you about $100-200 more.

The Good:
+ The various levels of height adjustment are great
+ All the parts fit together nicely and nothing feels loose
+ The spring action is on point and strong!

Then Bad:
- The one plastic part (the bag adapter) has broken all the way around the cone, within about 6 months. It's not a huge cost to replace, but is an annoyance to refit. For reference, I'm 5' 8", weigh 126 lbs, and I'm not slugging the cobra bag. I use it mostly for coordinating defense-to-offense drills for improving my philly shell. I don't know if I got a faulty piece or if it's just not made to last, but I expected it to last at least a year given my stature and approach to training with it.

- Unless you have a painted cement floor, the suction base probably won't work for you. I have a very flat and clean "Driftwood laminate floor" and it will not stick for anything. I've tried wetting it, weighting it, heating it, nothing works. I ended up bolting it into a large spare cutting board and weighing that down, which works perfectly.

Overall it's a great product and still worth buying for the quality vs. cost compared to other bags. If you're a DIYer this is your go-to cobra bag. Though I'd definitely recommend purchasing an extra adapter with the original order to avoid paying shipping on your very probable second adapter in the future.

Hi Mason, thank you for the review and the detailed feedback. I'm sorry about the Ball Adapter breaking on you. As a result of feedback like yours, I am releasing an upgrade for this part at the end of this month. The new Adapter will be a lot stronger and should not break.

Hits about the same as the fierce reflex bag Liked most everything about the bag except 2 things first is I wish u could make the bottom part talller without making the bag slower but making the top taller 2nd is the bag itself not sure if I didn’t tie it up properly but it almost feel like the bladder is going to come off I think this an issue on my part though beside that the bag works amazing good quality spring suction cups also work good some things that make them better are water or vitamins n e oil

I would have given 5 stars but they sent wrong size punch bag. I can always buy a different bag to swap out. But based on the price. You can’t beet it. These Kewlus bag with do more than your higher end expensive ones that don’t have the same ajustable pole. Even though these kinda drills and practices aren’t supposed to be hard. I’m a little afraid to punch it with 75% power but you can always change the pipes if your inclined on construction work. I ordered the suction cups as platform because I have gloss painted floors. I was having trouble a little bit at first with suction cups but if you clean area good and use vitamin E oil on button on suction cups or even vegetable spray, olive oil, they will lock down hard. Definitely worth getting. If you truly use your boxing equipment daily, weekly then I would say buy it.
