A retaining system for retaining and releasing an element, in particular an electrical energy store. The retaining system includes a mounting that is configured to accommodate and fix the element, the mounting being configured to removably accommodate the element in the mounting, and an intermediate element that is situated between the element and the mounting and configured to allow a damped motion, in particular for gentle accommodation, of the element in the mounting. The mounting includes a locking bar that is configured to be accommodated in a receptacle in a locking position, or the mounting includes a receptacle that is configured to accommodate a locking bar in a locking position.

A rechargeable battery pack (20) for an electric or hybrid vehicle (1), comprising: at least one electric connection member (23) to a powertrain unit (5) of the electric or hybrid vehicle (1); a plurality of mutually electrically connected cells (30); at least one first circuit block (40) integrated in the rechargeable battery pack (20) and comprising a radio communication interface (45).

Various personal mobility vehicles, such as scooters, are disclosed. The scooter can include at least one battery and motor for powering at least one driven wheel. The vehicle can include a gear assembly to convert a torque produced by the motor to a different torque to a driven shaft to power the at least one driven wheel. The battery can be removable.

A bicycle with removable battery for supplying power to electric components, comprising a frame composed of an upper tube connected with a front oblique tube and with a rear vertical tube, which in turn are connected in a lower region so as to form a seat for a bottom bracket and with which a pair of horizontal rear chainstays and a pair of oblique rear chainstays are coupled. The front oblique tube has an axial seat for a removable battery and for accommodating connection and/or electric power supply cables. The axial seat has an axis that passes above the bottom bracket and a lower end that is open and located at the interspace between the pair of horizontal rear chainstays.
