Suspension system for a bicycle and damper device

A suspension system for an, at least partly muscle-powered, vehicle, the suspension system comprising:

• at least one damper device formed with a first damper chamber and at least one second damper chamber coupled with one another via at least one controllable damping valve;
• a sensor disposed to detect data about a current state;
• an electrical control device connected to said sensor and a memory device, said control device outputting a control signal controlling, and influencing a damping characteristic of, said damper device;
• said damping valve having at least one damping channel and a field generating device associated therewith for generating a field and controlling a field strength in said at least one damping channel of said damping valve;
• and
• a field-sensitive rheological medium in said damping channel for controlling the damping characteristic of said damper device in dependence on the data detected by said sensor.
