We understand that a small weight saving can make getting in and out of the car that little bit easier, so imagine what a massive weight saving can do for you! The Sub4 glides effortlessly due to the lightweight and rigid frame, but don’t think we've compromised on quality.  The Sub4 boasts all the same reliability features as the TIGA, and with the frame being very similar in design and materials, you can be sure the Sub4 isn’t just super light, but it’s super strong too!
