A bicycle component for an at least partially human-powered bicycle has a shock absorber device. The shock absorber device includes a damper device which can be controlled by a control device. A detection device is provided with a sensor device for receiving a signal. The sensor device is arranged on at least one component of the bicycle which is pivoted in the case of a steering movement. The detection device is suitable for detecting, and is designed to detect, the difficulty in the terrain as a function of the acquired signal, and is configured to control the damper device as a function of the detected difficulty in the terrain, with the result that a damping property of the damper device can be adjusted by way of a signal of the detection device.

Bicycle component, bicycle and method

A chassis controller and method for controlling the damping of a human-powered two-wheeled vehicle having a controllable shock absorber and a control device and a memory device. A sensor device acquires measurement data sets relating to a relative movement of two connecting units of the shock absorber with respect to one another. A filter device pre-processes the measurement data sets. Multiple data sets are stored in the memory device. A data set, derived from a measurement data set acquired with the sensor device during the relative movement of the connecting units is stored and an analysis device analyzes a stored data set. A filter parameter set is determined based on the analysis, and a control data set is derived with the filter parameter set. The control device controls the shock absorber with the control data set.

Suspension control for a human-powered two-wheeled vehicle and method

A suspension control system and a method for controlling a damper device of a bicycle include a damper device and a spring device for sprung damping of a relative motion between a first and a second component of the bicycle. The suspension device has a spring unit exhibiting a spring characteristic, and the damper device exhibits a damping characteristic. The spring characteristic of the spring unit is changed under the control of an electrically operated actuator, which in turn is controlled via an electric control device.

Suspension control system for a bicycle, bicycle, and suspension control method

A chassis controller controls a shock absorber of a bicycle for spring-assisted damping of a relative movement between a first and a second connecting unit. A damper device and a spring device absorb shocks between the connecting units. A sensor device acquires measurement data relating to a relative movement of the connecting units. A control device controls the shock absorber. The sensor device has a scaling device connected to one of the connecting units and the sensor device extends over a measuring section in a direction of movement of the relative movement. The scaling device has a structure with magnetic properties that repeat periodically over the measuring section. The sensor device has a detector head which interacts with the scaling device, is connected to the other of the connecting units and determines a position of the shock absorber.

Chassis controller for a human-powered two-wheeled vehicle

A suspension fork for a bicycle includes at least one stanchion tube and at least one slider tube interacting therewith and a wheel receiving space adjacent thereto. The suspension fork includes a damper system with a damper chamber divided into a first chamber and a second chamber by a movable piston. The suspension fork further includes a damping device for the rebound stage and a damping device for the compression stage are provided. A shut-off valve is provided for selectively locking the rebound stage. The damper chamber comprises a connecting duct with a flow damper that connects the second chamber with the first chamber when the stanchion tube and the slider tube interacting therewith are compressed more than a predefined distance such that in the case of a forceful compression and with the shut-off valve of the rebound stage activated, slow decompression is allowed up to a damper position as defined by the predetermined distance.
