Abstract

There is provided a transmission device for chainless bicycle, which includes: a front driving unit, a transmission unit, and a back driving unit. The front driving unit includes a front housing base and a rotating member rotatably mounted in the front housing base. The transmission unit includes a jointing member driven by the rotating member of the front driving unit to rotate around the line axis of itself, and a back spiral gear mounted at the rear of the jointing member and pushed by the jointing member. The back driving unit includes a back housing base disposed at the rear of the front housing base, and a spiral gear mounted in the back housing base and engaged with the back spiral gear for being driven to rotate. The power of the front driving unit can be transferred to the back driving unit via the transmission unit. The above design is suitable for being mounted on bicycle frames of various sizes, thereby providing diversified applicability.
