The inGear integrates onto the existing shafts and bearings. In addition, inGear provides some speed reduction, reducing gear costs
In the below illustration the inGear variable sprocket is mounted to the differential spider where it is driven by a belt or chain via a solid sprocket attached to the motor speed reduction gear.
As an example, the inGear could provide 3 speeds with greater than 2:1 ratio range. In such a configuration, the inGear does not add bearings or shafts to the drive train design, and can be inexpensive and compact.
Some vehicles such as the Chevrolet Volt already employ a chain drive that the inGear could be operated with.
