Abstract: A bicycle battery assembly comprises a bicycle frame tube, such as a down tube. A battery is adapted to be inserted through a battery opening in the longitudinal direction of the bicycle frame tube. For allowing for a simple fixing of the battery to the bicycle frame tube, in particular by means of screws, an installation aid is connected to the battery and/or the bicycle frame tube, in particular in the area of the battery opening. The installation aid allows for an easy installation since in particular screw holes in the bicycle frame tube are flush with threaded bore holes in the battery.

Abstract: The present disclosure is related to a field of e-bikes that discloses a bicycle frame tube, which may be a down tube of a bicycle frame. The down tube includes at the bottom-bracket-side end a battery opening facing in the longitudinal direction of the down tube such that a battery can be inserted into the opening from below. Further, the battery may be switched on and off by a switch provided at the battery. The bicycle frame tube may include a switch opening such that a mechanical switch with an operating element may be arranged in the switch opening to mechanically actuate the on/off switch of the battery. Furthermore, a charging plug as well as a charging condition indicator may be provided at the lower end of the battery or the battery housing of the battery.

Abstract: A bicycle frame tube which is in particular a down tube of a bicycle frame comprises a battery opening for inserting or removing a battery. Inside the bicycle frame tube a holding element for holding the battery is arranged. The holding element is at least partially elastically deformable, wherein the holding element in particular comprises two abutment elements which are elastically deformable.

Abstract: A battery unit for a bicycle having an electric motor, including a battery case having an upper side, a lower side and two sidewall several energy cells arranged in the battery case, and a battery management system electrically connected to the energy cells, where the battery management system is arranged on one of the two sides.

Abstract: A steering system for bicycle handlebars includes a steer tube pivotably supported in a head tube of a bicycle frame via two bearing elements. A first stop element is connected to the steer tube to limit the steering lock. A second stop element is connected to the bicycle frame, in particular the head tube. The first stop element is arranged inside the head tube between the two bearing elements.

Abstract: A bicycle frame sealing means includes a frame-side sealing element adapted to be sealingly connected with a saddle tube of a bicycle frame. A saddle post-side sealing element is adapted to be sealingly connected with a saddle post. Both sealing elements are interconnected by means of a flexible connecting elements, so that relative movements can occur between the two sealing elements or between the saddle tube and the saddle post, while a good tightness is still ensured.

Abstract: A bicycle frame element includes a frame tube which is a top tube, a down tube or a saddle tube of a bicycle frame. The frame tube includes a recess for storage of bicycle accessories such as tools, a bicycle pump, a rain coat or the like. The recess has at least one holding element extending across it. In the area of the recess, the frame tube is formed as a profile closed in a circumferential direction so that the recess has merely a slight influence on a stiffness of the frame tube.

Abstract: An e-bike frame includes a top tube, a downtube and a seat tube. Further, a bottom bracket is arranged in a housing which may be a bottom bracket receptacle element. An electric motor is also provided in the housing. A battery is connected with the downtube. A channel element is arranged laterally beside the battery. The same serves to receive wires, shift cables, brake cables and/or hydraulic lines.

Abstract: A rear hub for mountain bikes includes a hub body and a sprocket carrier rotatably provided on a hub axle. The hub body is coupled with the sprocket carrier via a freewheel mechanism. By providing a decoupling mechanism, it is possible to decouple the sprocket carrier from the hub body.

Abstract: A vehicle frame, in particular a mountain bike frame or a trekking bicycle frame, comprises main frame element. A rear frame is pivotably connected with the main frame element. A damping element is provided between the rear frame and the main frame element. A first connection point of the damper element is connected with the rear frame and a second connection point of the damping element is connected with the main frame element. For the purpose of changing the frame characteristics, a displacing element is provided for the displacement of the first connection point. The locking of the displacing element is done with the help of an actuator element.

Abstract: A bicycle fork with an integrated brake unit, in particular for racing bicycles and time-trial machines, comprises a fork crown connecting two fork legs with each other. A bottom bearing seat is connected with the fork crown. A brake unit is arranged below the fork crown, wherein an activation element, such as a Bowden cable or the like, for activating or actuating the brake unit is passed through the bottom bearing seat.

Abstract: A double bridge bicycle fork with integrated brake unit, suited especially for racing bicycles and time-trial machines, comprises two fork legs connected by a fork crown. Further, a bottom bearing seat is connected with the fork crown. A steer tube is provided in front of the rotational axis of the fork, seen in the direction of travel, said axis being defined by the bottom bearing seat and the upper bearing seat. The steer tube is connected with the stem by means of screws. This makes it possible not to provide a rigid head tube between the two bearing seats, but to arrange a sleeve in the embodiment illustrated that has an opening for passing actuation elements therethrough, such as switching or brake cables.

Abstract: A bicycle fork, particularly a bicycle fork for a racing bicycle, comprises two fork legs connected to each other by a fork bridge. On the respective dropout ends of the fork legs, recesses are provided for receiving a front-wheel axis. For allowing the front-wheel axis to be arranged in different positions in the longitudinal direction of the frame and, thereby, to be able to change the trail, a positioning element is arranged within the recesses. The positioning element can be turned by 180° and thus be inserted into the recess or be exchanged in different positions. Effected thereby is a change the position of an opening which serves for receiving a front-wheel axis.
