  • Patent number: 10919599
    Abstract: An electric drive for a bicycle is disclosed. The drive includes an electric motor including an drive shaft, a driven shaft connected in a rotationally fixed manner to a driving gear for coupling to a wheel drive, and a transmission structured and arranged to drivingly connect the drive shaft to the driven shaft. The transmission includes a driven wheel, which is connected in a rotationally fixed manner to the driven shaft in a rotational drive direction, and at least two output gears. The at least two output gears includes a first output gear and a second output gear that each engage with the driven gear offset to one another in a circumferential direction to drive the driven wheel.

  • Patent number: 10843770
    Abstract: An electric drive for a bicycle includes an electric motor having a drive shaft, a driven shaft connected in a rotationally fixed manner to a driving gear for coupling to a wheel drive of the bicycle. The electric drive includes a transmission, which drivingly connects the drive shaft to the driven shaft. The transmission has a driven wheel, which is connected in a rotationally fixed manner to the driven shaft in a rotational drive direction, and at least two output gears, the at least two output gears including a first output gear and a second output gear, which in each case engage with the driven gear offset to one another in the circumferential direction in order to drive the driven wheel; and wherein the transmission has a power distribution, which divides a drive power of the electric motor to the output gears.
