An adsorption refrigeration device includes a first chamber with an adsorber/desorber material and a second chamber with an evaporator/condenser device. The first and second chambers are in fluid connection via a pipeline. The fluid connection between the chambers is blocked in a first functional position and opened in a second functional position via a valve device that is arranged in the pipeline. The valve device has a valve element with a variable diameter. The valve element has two functional positions. In the first functional position, the valve element has a first diameter by which it fills an internal cross section of the pipeline with tight contact with an inner wall of the pipeline. In the second functional position, the valve element has a second diameter that is smaller than the first diameter such that a gap is opened between the inner wall of the pipeline and the valve element.

A method for detecting wear on at least one component of an electric bicycle includes: monitoring the operating condition of the at least one component with the aid of at least one sensor; detecting the stress on the component over the duration of operation; and displaying the need for service on a display unit as soon as a long-term load threshold defined for this component is reached, to inform the cyclist promptly of the need for service.
