StepTwin ® Bike: Each leg has a separate drive.
All your power directing into the downward stroke. This is termed the "drive phase". You can end the drive phase with any leg at any time. You can relax any leg at any time.


The pedals lift automatically, there is a servo to lift them.

Besides, you can adjust the lifting force for each pedal separately.



Legs move exclusively vertically
StepTwin® Bike, perfect for training your leg, hip, seat, and upper body muscles. You can choose any cadence for each leg. Your muscular system can contract and relax at any rhythm. In other words, as the right leg pushes down, the left leg can push down too.

We analyzed many bicycle drives




Svea Bicycle
The Sveavelocipede was Brothers Birger and Fredrik Ljungström's first patent dating from 1894. Alfred Nobel had tested the bike and then invested in marketing and manufacturing.

Levocyclette Terrot
This model was the first bicycle to have ten separate gears that were changed by way of a meshed gear twist grip mechanism. This costly bike was produced between 1905 and 1924.

Alenax / Transbar Power BicycleThe Transbar idea was conceived by Marn T. Seol, a Korean inventor. He sold his idea to Byung D. Yim, a Korean entrepreneur, who brought it to the United States in the early '80s.

And many other bicycle drives

Rear hub
We have developed a Unique Hub for the rear wheel of a StepTwin® Bike. This hub allows you to rotate the wheel of the bike through the use of two completely independent chain StepTwin® Drives.

StepTwin® Prototypes
We have created more than 10 variants of the bike stepper drive.

Manufacturing of frame parts.

The final prototype of the StepTwin® Bike frame.

Riders and engineers
Walking and cycling are gaining popularity to maintain good physical fitness and promote health. This trigged our imagination to create a product that would combine both walking and biking. We created the challenge to develop two independent drives for a bicycle. After 10 prototype iterations, we have finally produced a StepTwin® Bike we’re proud of.

And we love it!
