  • Patent number: 10858059
    Abstract: A unitary system for an electric-assist bicycle generates signals indicative of power input to a drive system of the bicycle when a rider pedals the bicycle, considering torque applied by the rider, as well as the cadence or speed of the rider's pedaling. Direction of pedaling is also measured using the system. The system utilizes fixed, hard-wired, contactless electronics, namely first and second inductance coils that are non-equally-spaced circumferentially around a first axis, and which generate a first electrical signal indicative of torque based on lateral movement of a conductive or otherwise magnetically permeable rotatable member relative to the coils, and which generate second and third electrical signals indicative of pedaling cadence and direction based on eccentric relative rotational movement of the conductive or otherwise magnetically permeable rotatable member relative to the first and second inductance coils.

  • Patent number: 10745072
    Abstract: The invention relates to a bicycle, with a bicycle seat assembly rotatably connected to the bicycle. Rotation movement of the bicycle seat assembly is possible, seen in the driving direction, to the left and to the right side and is independent of the steering movement of the bicycle. The axis of rotation of the bicycle seat assembly is arranged in front of the axis of the bottom bracket, seen in the driving direction, and the seating surface of the bicycle seat is arranged behind the axis of the bottom bracket, seen in the driving direction. The rotatable bicycle seat assembly enables an upright riding position by dodging the cyclist's leg pedaling downwards through a rotational movement. At the same time it supports the hip side of the other leg. The driver is supported by the bicycle seat even in the upright riding position.
