FAQ

What is the height range of the Kewlus Cobra Bag?

The full kit that includes the PRO Spring has a height range of 4'5 (134 cm) - 5'4 (163 cm). It's designed to be used by kids and adults up to about 6 feet in height. If you're much taller than that, you can make a custom base to suit your height by following these DIY instructions.

How does the Kewlus Cobra Bag compare to other cobra bags on the market?

The Kewlus Cobra Bag is a completely modular system that is unlike any other cobra bag. Everything simply clicks together and components can be swapped on-the-fly. The bag itself, for example can be used as a training aid just like a focus mitt and you'll be able to swap to different sized bags as you train.

My plan is to release different variations of some of the components, such as different size bags, different springs, as well as add-ons such as a spar bar add-on at a later stage. It's the beginning of a complete boxing and MMA modular training system.

Can I use my old cobra bag and simply replace the spring and/or top section?

Yes it may be possible, however you'll need to consider some key things. Firstly, the Kewlus Pro Spring is specifically designed and rated for either the Kewlus top section kit or the DIY version, so your old cobra bag top section may simply be too heavy to be effective. Secondly, I myself and many others have tried this and it doesn't quite work. However I don't wish to discourage you from trying, so give it a go and if it works, let us know!
