For bicycles _f . which are driven by an auxiliary motor _f a sprocket is placed on the freewheel of the wheel. So far, a special item has been made for this Eweok with which the sprocket is firmly connected. This means - increased by HersteüLungskosten -Me special production and increased Aufvmnd of storage, it is to be able, therefore, desirable _v Install the sprocket for the servo motor drive on a normal freewheel hub.
