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

A suspension control system for an at least partially muscle-powered two-wheeled vehicle, the suspension control system comprising:

• at least one damper device and at least one spring device for sprung damping a relative motion between a first component and a second component of the vehicle;
• said at least one damper device having a damping characteristic;
• said at least one spring device having at least one spring unit with a variable spring characteristic;
• at least one electrically operated actuator configured to vary the spring characteristic of said spring unit;
• and
• an electric control device for controlling said actuator;
• said damper device containing magnetorheological fluid and including at least one magnetorheological damping valve, said damping valve has a damping characteristic that is adjustable by said electric control device, and wherein the damping characteristic of said damping valve and the spring characteristic of said spring unit are adjustable by way of said electric control device;
• and
• a memory device configured to define, together with said control device, at least one characteristic damper curve being a function of a damping force over a relative speed between the first and second components;
• at least one sensor device connected to said control device and configured for periodically obtaining a current characteristic value of a current relative speed between the first and second components;
• and
• said control device being configured to derive, from the current characteristic value and the characteristic damper curve stored in said memory device, a pertaining current setting for said controllable damping valve and to set said damping valve accordingly to adjust a current damping force ensuing from the characteristic damper curve based on the current characteristic value thus obtained.
