FREE POWER FG1 is the world’s first bicycle gear system with silicone inside the gears.

The silicone inside the gear is compressed by the force from stepping on the pedals, and the counteracting force is turned into energy to support the rotation of the gears.
At the same time, the silicone absorbs stress on the joints, muscles, and bones of the feet, reducing stress on the whole body.
