A wind turbine comprising: a shaft (2); a plurality of blade arrangements (8), each of which is rotatable around the shaft and has a blade (7), said blade arrangements and blades forming a blade rotor which is rotatable around the shaft; at least first and second bearing arrangements (6) spaced axially along the shaft, said blade rotor being connected to said first and second bearing arrangements; and a direct drive generator comprising a stator (10), which is rotationally fixed to the shaft, and a generator rotor (9) having a rim; wherein the first and second bearing arrangements each transmit radial forces from the blade rotor to the shaft, and at least one of the first and second bearing arrangements transmits bending moments to the shaft, each of the blade arrangements being connected to a point at or adjacent the rim of the generator rotor so as to transmit torque generated by the blade arrangement directly thereto, and wherein the generator rotor (9) is within the blade rotor.
