A two speed transmission (100) and belt drive system utilizing the transmission (100). The two speed transmission (100) comprises a planetary gear train comprising an input pulley (10) connected to an input carrier (20), and a sun gear (18) and a ring gear (17). The input carrier (20) also comprises a plurality of planetary gears (15) disposed between the sun gear (18) and the ring gear (17). The sun gear (18) is engaged with an electromagnetic brake member (190). The ring gear (17) is engaged with an output pulley (30). A one-way clutch (22) is disposed between the input (20) carrier and the output shaft (31). The brake member (190) is engaged at engine idle and is disengaged at engine speeds above idle. When the brake member (190) is engaged the sun gear (18) does not rotate, thereby driving the ring gear (17) and output pulley (30) at a greater speed than the input pulley (10).
