Bicycle seatpost assembly

A bicycle seatpost system comprising:

• an electric actuator to change a state of a bicycle seatpost assembly between
• a lock state where a total length of the bicycle seatpost assembly is invariable, and
• an adjustable state where the total length of the bicycle seatpost assembly is variable;
• a remote controller configured to transmit
• a first control signal, and
• a second control signal different from the first control signal;
• and
• a seatpost controller configured to control the electric actuator to change the state of the bicycle seatpost assembly to the adjustable state based on one of the first control signal and the second control signal,
• the remote controller including a first operating part configured to receive a first user input,
• the remote controller being configured to generate the first control signal in response to the first user input in a case where the first operating part is operated by a first number of operation times within a predetermined period,
• the remote controller being configured to generate the second control signal in response to the first user input in a case where the first operating part is operated by a second number of operation times within the predetermined period,
• the second number of operation times being different from the first number of operation times, and
• the remote controller being configured to generate the first control signal having a signal length different from a signal length of the second control signal.
