The present invention relates to a bicycle propelling device capable of transferring power to a bicycle wheel by using the gripping force of both hands. The present propelling device uses the gripping force, and thus overcomes the problem of prior art hand and foot bicycles in which balance is easily lost during driving because the prior art hand and foot bicycles require the use of the arms. The propelling device can be used together with a pedaling operation when greater power is required while the user is riding the bicycle as usual, thereby improving the running efficiency of the bicycle. Furthermore, the propelling device is formed by combining simple devices including a string and a freewheel, and thus a bicycle can maintain the original structure thereof as it is, so that it does not cause any disadvantage or difference when the user rides the bicycle by stepping on pedals in a conventional manner.
