At least one of the modules is replaceable and handleable in one piece. At least one of the modules includes at least one sub-assembly that is replaceable and handleable in one piece. In an embodiment the modular construction system is configured to use at least one family of sub-assemblies comprising at least two family members within at least one of the modules.

Abstract: A bicycle operating apparatus for wirelessly controlling at least one component of a bicycle includes a carrier element on a fastening device for fixing the bicycle operating apparatus to a handlebar of the bicycle, a housing attachable to the carrier element having an energy storage compartment for receiving an energy storage element and having an electronic circuit arrangement in the housing. At least one switch is connected to the electronic circuit arrangement on the housing. An operating component mounted on the carrier element to be pivotable about an operating axis preloaded into a neutral position which is able to be deflected out of the neutral position in a first direction of rotation about the operating axis in order to actuate the switch, and the operating axis extends obliquely with respect to the flat outer surface.

Abstract: A control device for a bicycle is arranged or can be arranged on the handlebar of the bicycle and serves to wirelessly drive at least one electronic, electrical, electromechanical or electrohydraulic component of the bicycle. The control device includes an operator control arrangement which has at least one manually operable operator control element and is designed to respond to operation of the operator control element and to output electrical signals which represent the operation. The control device also includes at least one electronic circuit arrangement comprising a radio communication circuit and a control circuit which is connected or can be connected to the operator control arrangement. The control device also may include at least one antenna which is connected or can be connected to the radio communication circuit or which is integrated into the said communication circuit.
