A bicycle is disclosed having a control system with a user interface and an active suspension system. A user interface of a programmer allows a user to define stimulation therapy by interacting with one or more representations of the lead that delivers the therapy. The system classifier is used to assess current mood state, predicted instability, andor a change in future mood state, in particular for subjects with bipolar disorder. The slider and the mounting element move along the guide rail. The method includes measuring at least one inductive ratio for the cable, determining an inductive gap from the at least one inductive ratio, measuring a parallel impedance of the cable, and determining a resistance of the cable based on the inductive gap and the parallel impedance. The outer tube is designed to resist an outer pressure at least higher than 100 bar.
