PURPOSE: An electric bicycle equipped with a manual transmission is provided to sharply reduce a manufacturing process and parts and to improve work efficiency by simplifying the structure. CONSTITUTION: An electric bicycle equipped with a manual transmission comprises a driving shaft(61) transmitting the rotary power of a motor(60), a driving gear(62) connected with the driving shaft, an interlocking gear(63) with the driving gear, a first rotating shaft(66) supporting the interlocking gear and transmitting the rotary power of the interlocking gear, a clutch(70) connected with the first rotating shaft and having a friction plate(70a) jointed with the friction plates(64a,65a) of a first low-speed gear(64) and high-speed gear(65), a gear shifting lever, a second high-speed gear(69) interlocking with the first high-speed gear and transmitting the rotating power to a second rotating shaft(67), a second low-speed gear(68) interlocking with the first low-speed gear transmitting the rotating power to the second rotating shaft, the second rotating shaft supporting the second low and high-speed gears and transmitting the rotating power to a friction gear(90), and a friction gear having a free gear built-in operating a tire(5) with the rotating power of the second rotating shaft.
