It may be provided that a shared wear parameter for multiple wear parts or in each case separate wear parameters for individual wear parts is/are generated, determined, or formed. Typical components on a two-wheeler, in particular on a bicycle, that may be subject to wear include the brake pads, the brake disks, a sprocket, a chainring, a chain, or a tire. In addition, brake fluid in a hydraulic brake may also be subject to wear, it being possible for the brake fluid to absorb either air, water, or dirt, thus impairing the responsiveness of the pressure transfer. ## Claims ### Claim 1 A method for generating a wear parameter that represents wear of at least one wear part at a two-wheeler, the method comprising the following steps: detecting at least one weight force parameter; and detecting at least one use parameter of the two-wheeler; detecting at least one intensity parameter of a use of the two-wheeler; and determining at least one wear parameter for at least one wear part as a function of the at least one weight force parameter and the at least one use parameter and the at least one intensity parameter. ### Claim 2 (depends on 1) The method as recited in claim 1, wherein the two-wheeler is an electric bicycle. ### Claim 3 (depends on 1) The method as recited in claim 1, wherein at least one operating parameter of the two-wheeler is detected, a parameter that represents: (i) a temporal profile of a speed and/or acceleration at which the two-wheeler travels, and/or (ii) a delivered drive torque or a generated drive power of a drive unit of the two-wheeler, and/or (iii) a pedaling torque generated by a rider of the two-wheeler, is detected as an operating parameter, the at least one intensity parameter being determined as a function of at least one average value, and/or a variance, and/or a summation, and/or a weighting of at least one of multiple operating parameters, and wherein the operating parameter and/or the intensity parameter since a predefined point in time, is detected or determined. ### Claim 4 (depends on 1) The method as recited in claim 1, further comprising: comparing the wear parameter to a first threshold value; and generating a piece of wear information when the wear parameter reaches or exceeds the first threshold value. ### Claim 5 (depends on 1) The method as recited in claim 1, wherein a parameter that represents a weight of at least the two-wheeler, and/or a weight of a rider of the two-wheeler, and/or a weight of a trailer of the two-wheeler and/or a weight force at a trailer hitch of the trailer at the two-wheeler, and/or a load on the two-wheeler, is detected as a weight parameter. ### Claim 6 (depends on 1) The method as recited in claim 1, wherein at least one parameter that represents: kilometers traveled by the two-wheeler, and/or a use time of the two-wheeler, and/or a number of braking operations, and/or an intensity of the braking operations as a function of the brake pressure generated at the brake, is detected as the use parameter, the use parameter being detected since a predefined point in time. ### Claim 7 (depends on 1) The method as recited in claim 1, wherein the wear parameter is determined as a function of a weighting of the at least one weight force parameter, the at least one use parameter, and the at least one intensity parameter. ### Claim 8 A device, comprising: an evaluation unit configured to generate a wear parameter that represents a wear of at least one wear part at a two-wheeler, the evaluation unit configured to detect at least one weight force parameter; detect at least one use parameter of the two-wheeler; detect at least one intensity parameter of a use of the two-wheeler; and determine at least one wear parameter for at least one wear part as a function of the at least one weight force parameter and the at least one use parameter and the at least one intensity parameter. ### Claim 9 (depends on 8) The device as recited in claim 8, wherein the two-wheeler is an electric bicycle. ### Claim 10 (depends on 8) The device as recited in claim 8, wherein the evaluation unit is further configured to: compare the wear parameter to a first threshold value; and generate a piece of wear information when the wear parameter reaches or exceeds the first threshold value. ### Claim 11 (depends on 8) The device as recited in claim 8, wherein the evaluation unit is further configured to: controls a component of the two-wheeler as a function of the wear parameter to reduce a further increase of the wear parameter, the evaluation unit being configured to control the component to reduce the further increase when a second threshold value is reached or exceeded. ### Claim 12 (depends on 8) The device as recited in claim 8, wherein the evaluation unit is further configured to: send a piece of information via a wireless link to a central database as a function of the wear parameter. ### Claim 13 (depends on 12) The device as recited in claim 12, wherein the piece of information is an exceedance of the wear parameter of a first threshold value. ### Claim 14 A two-wheeler, comprising: a weight sensor configured to detect at least one weight force; a vehicle dynamics sensor configured to detect a use parameter and/or operating parameter of the two-wheeler; and an evaluation unit configured to: detect the at least one weight force parameter using the weight sensor, detect the use parameter of the two-wheeler, detect at least one intensity parameter of a use of the two-wheeler, and determine at least one wear parameter for at least one wear part as a function of the at least one weight force parameter and the use parameter and the at least one intensity parameter. ### Claim 15 (depends on 14) The two-wheeler as recited in claim 14, wherein the two-wheeler is an electric bicycle.
