The present invention relates to a transmission for a chainless bicycle, including a drive assembly in which multiple drive bevel gears with different sizes are arranged in concentric circles and which operates in conjunction with pedals, and a driven assembly which includes multiple driven bevel gears engaged with the drive bevel gears, respectively, and a driven shaft connected to a rear wheel. Especially, the transmission of the chainless bicycle includes a needle bearing housing which is configured to be meshed with or separated from the inner circumference of a hollow portion of a selected driven bevel gear according to whether a sliding member is coupled to the needle bearing housing forcibly coupled to rolling units prepared in multiple rounding grooves formed at one side of the driven shaft, thereby enabling drive force by the drive bevel gear to be delivered to a specific driven bevel gear for changing gears. Moreover, the needle baring housing forcibly coupled to upper portions of the rolling units receives, instead of the rolling units, a determination about whether to interfere by connection or release of the sliding member, thereby facilitating the connection or release of the rolling units and the sliding member.
