Abstract
A component for a human-powered vehicle basically includes a transmission device, a shaft member and a speed increaser. The transmission device includes a plurality of transmission stages. The shaft member is spaced from an input rotational shaft of the human-powered vehicle and arranged on the shaft member. The speed increaser is configured to transmit a human driving force that is input to the input rotational shaft to the transmission device. The speed increaser includes at least one first planetary gear group. The at least one first planetary gear group is rotatable about a rotational center axis of the shaft member.

A component for a human-powered vehicle, the component comprising:
- a transmission device including a plurality of transmission stages;
- a shaft member spaced from an input rotational shaft of the human-powered vehicle, the transmission device being arranged on the shaft member;
- a speed increaser configured to transmit a human driving force that is input to the input rotational shaft to the transmission device;
- and
- an output rotor configured to output a driving force that is output from the transmission device,
- the speed increaser including at least one first planetary gear group,
- the at least one first planetary gear group being rotatable about a rotational center axis of the shaft member, and
- the output rotor being arranged coaxially with the shaft member.
