We change the transmission. You transform the system

Varionova develops next-generation, AI-ready transmission systems, that can deeply change the mechanical systems they become part of. Our flagship RatioZero technology is the world's first commercially viable gear-based CVT, a real breakthrough delivering the efficiency of traditional gears with smooth, stepless control. Around, it we are developing a host of innovative, step- and stepless transmissions.

The Technology Advantage

Traditional transmissions force you to choose: high efficiency with fixed gears, or smooth ratio variation with significant friction losses. We've eliminated that compromise with the first commercially viable gear-based CVT—combining continuous control with mechanical efficiency. A game changer that opens to countless new possibilities.

Continuous variation

Proprietary "split rotation" principle enables stepless ratio control through gears -- an absolute world first.

Energy efficient

Gear-based design delivers minimal friction losses, reducing heat generation and extending component life.

High torque

Scalable load transfer mechanism handles any torque requirement, from precision robotics to heavy-duty industrial applications.

Effortless control

Independent shifting mechanism enables smooth ratio changes under full load, with simple control systems.

Applications

Our technology adapts to diverse mechanical challenges across industries

E-bike hub transmission
E-bike Hub Drive

A never-before-seen transmission combining the efficiency of a cassette with the smoothness of a CVT, creating an entirely new pedaling experience--and energy-optimal.

EV
Integrated EV transmission

An efficient, compact CVT-type transmission enabling continuous ratio optimization of EV powertrains, to keep them operating at peak efficiency for maximum performance and range.

Power Take Off
Simple yet Efficient Power Take Off

The RatioZero allows to reverse the current approach to PTO: the engine can run at a fixed (optimal) ratio, and the highly-efficient CVT ensures to match the implement with high-efficiency, mechanical power transfer.

Electrohydraulics
Electrohydraulics Cost-reduction Enabler

Both conventional and electrified machines use this kind of sub-system, often with variable axle piston pumps. The RatioZero allows to shift to a constant speed motor and fixed displacement pump, saving space and costs.
