Abstract: A data management device for a two-wheeled vehicle, in particular an e-bike, pedelec, or the like, for the management and/or the diagnosis of operating data of the two-wheeled vehicle. The device includes a first communication interface for wireless communication with wireless two-wheeled vehicle devices of the two-wheeled vehicle, a second communication interface designed for communication with at least one two-wheeled vehicle system device, a third communication interface for the in particular authenticated and/or encrypted communication with a diagnostic device for the at least partial provision, modification, deletion, and/or retrieval of operating data of the two-wheeled vehicle, and a data management component for the management of operating data of wireless two-wheeled vehicle devices. The data management component being connected to the third communication interface and being designed to receive, to modify, to delete, and/or to provide operating data.

Abstract: A method for replacing a drive unit of a vehicle, in particular of an electric bicycle, includes (i) capturing identification features of a first drive unit of a vehicle by way of a first service device, wherein the identification features uniquely represent the first drive unit, (ii) transmitting the identification features from the first service device to a second service device, (iii) generating configuration data by way of the second service device on the basis of the identification characteristics, (iv) transmitting the configuration data from the second service device to the first service device, (v) providing a second drive unit at the first service device, and (vi) configuring the second drive unit by way of the first service device using the configuration data.

Abstract: A universal chuck is presented which has the ability to either transmit a tensile or pulling force to the end of a piercing rod or transmit a rotational moment or force to a drill bit on a piercing machine for piercing a tap hole of a shaft furnace. The universal chuck of this invention comprises a rotary body mounted on the drive spindle of a working member slidably mounted on a piercing machine. A suitable support structure integral with the working member forms a guide cage around the rotary body. Structure for transmitting the tensile or pulling force to the end of a piercing rod and a rotational moment or force to a drill bit along with structure for adequately controlling operating and cooling fluids to a drill bit are arranged about a front cavity in the rotary body.
