Experience the world’s first alternative CVT innovations patented across the globe. Successfully developed and tested for low cost manufacturing, fuel efficiency and reduced emissions to minimise environmental impact.

Varibox Products


ROTORcvt is the flagship invention of Varibox with the first patent filed in 2005. This product is a pure mechanical two stage ratcheting CVT functioning on a positive mechanical engagement and totally divorced from dynamic friction. Read more


icvt by Varibox is suitable for any high torque and power application where variable speed is required. It is a purely mechanical incremental CVT in which the ratio is adjusted in increments (typically 64 ratios) without any power interruption. Read more


RADIALcvt is the latest invention by Varibox. RADIALcvt is a multi, parallel power path CVT with only one steel on steel friction drive interface in each path. Read more


Varibox currently has 3 protected CVT innovations that are patented across 13 countries globally. The ROTORcvt and icvt have been proven under load via tested prototypes and various simulations. The RADIALcvt has been in development since 2015 and provides a unique configuration in friction drive CVT technology

RADIALcvt-The Ultimate Commercial CVT

Current commercial CVT's in the passenger vehicle market face criticism for being laden with inherent deficiencies like hydraulic control losses, friction drive losses, high manufacturing costs, high contact stresses requiring special materials, as well as being heavy, which results in expensive and heavy CVT solutions which are not sufficiently viable in small vehicles below 50 kW. For this reason, Varibox CVT Technologies Pty (Ltd) developed the RADIALcvt, a multi-parallel power path type of CVT that consists of only one steel-on-steel lubricated friction drive interface in each power path.
