FIELD: transport engineering: bicycles.
SUBSTANCE: invention relates to electric drives of bicycle speed change control devices. Connecting member 150 is installed for rotation by electric motor and it provides articulated coupling of member 108, 130 with base member 44 or movable member 158. parts 150A, 150B of connecting member 150 pass through opposite holes in case 56 of electric motor, being arranged in opposite holes 116, 154 in coupling member 108, 130. drive member 204 can be installed for rotation together with connecting member 150, being connected with rotation energy accumulator 218 of connecting member 150. Clutch can be installed in line of transmission of force between motor and connecting member 150. motor can be arranged in coupling member 94, 108, 130 for rotating connecting member 150 through worm wheel or bevel gear. Sprocket rotation check sensor can be secured to base member 44. mechanism to determine position of movable member 158 relative to base member 44 can be connected through connecting member 150.
EFFECT: compact design, resistance to contamination.
