To realize a unit sales system of an electromotive power assisted bicycle that provides a broad range of flexibility in conformity with requirements of a user, a server computer-for distributing an electromotive power assisted bicycle according to the present invention comprises a control section-for providing a general control and management of the computer, a hard disk-for storing a set of a variety of information for providing the electromotive power assisted bicycle, and a modem-enabling the connection to a variety of different terminals via a communication network. The hard disk-stores bicycle information, electromotive power assisting information, user information, physical strength/health information, a variety of different control programs to be downloaded, information about a supplier to which an order is issued, and information about an assembly station and so on. The server computer-, in response to an order from the user via the communication network-, creates design information for assembling an electromotive power assisting kit-with an ordinary bicycle unit having a traveling function basically provided by a pedal effort, and sends it to the suppliers and the assembler so that a tailored electromotive power assisted bicycle-can be delivered to a user.

An aqueous ink composition for ball-point pen is provided which includes an aqueous ink mixture containing at least a coloring agent, a dispersant, a water-soluble organic solvent and water, and a compound of the general formula (1): ##STR1## wherein R1 and R2 represent OH and/or HO(CH.sub.2 CH.sub.2 O)n and/or ##STR2## where Y is CmH2m+1 (m is an integer of not larger than 4); and X represents an alkali metal salt, amine salt or alkanolamine salt. The aqueous ink composition is excellent in lubricity, wear resistance of ball seat, writing touch and long-term stability, and is less liable to feather on paper.
