FREE POWER（フリーパワー）

The world’s one and only bike crankset which took 10 years to develop.
3 cycle mechanism
The silicone is compressed by stepping on the pedals.
The elastic silicone will compress the force as energy while reducing the impact on the feet when you’re stepping.
While maintaining the counteracting force, you’ll reach a “dead zone” a point where the force is interrupted when the pedals are at an up-down position.
The counteracting force from the silicone stored at the dead zone is then converted into gear propulsion and moves forward as it’s being pushed out.
About 200 years since the birth of bicycles
Despite various improvements and evolutions, dead zones remain to be unsolved
FREE POWER is the world’s first revolutionary gear system that has solved this dead zone problem
With the counteracting force from the silicone, an more efficient and smoother rotation is achieved
※ Tested with normal city bikes
Crank input range based

The counteracting force from the silicone eliminates dead zones for a smoother pedaling
The silicone acts as a buffer to absorb the impact on the knees and muscles
