A shock absorber comprising a generally tubular body defining a working chamber. A piston is slidable in the working chamber and separates a compression chamber from a rebound chamber of the working chamber. The working chamber contains damping fluid. The shock absorber comprises an electric generator fitted thereto. The generator comprises a turbine rotatably coupled to at least one magnet and coils adjacent the magnet. The shock absorber comprising a turbine flow path between the compression chamber and the rebound chamber, the turbine being supported for rotation in the turbine flow path driven to rotate by flow of damping fluid. Preferably the turbine flow path comprises a compression flow path and a rebound flow path and a turbine chamber, the compression flow path providing for flow of damping fluid from the compression chamber though the turbine chamber to the rebound chamber. One way valves are positioned in the compression and rebound flow paths so that flow only occurs in a respective flow path during compression and rebound of the piston. Movement of said damping fluid though either of said compression flow path or said rebound flow path causes the turbine to rotate in only one rotary direction to thereby generate an electric current in said at least one coil.
