Various embodiments provide for a bike-supported communication network that manages and facilitates communications between components of an electric bicycle and a wireless network. In some embodiments, the systems and methods provide a lock assembly for an electric bicycle, having a lock module that is configured to lock a rear wheel of the electric bicycle and a communication module that facilitates wireless communications between the electric bicycle and a communications network.

A bike includes a frame elongated in a longitudinal direction, a front fork rotatably engaged with a front wheel at a front end of the bike, a rear fork rotatably engaged with a rear wheel at a rear end of the bike, a handlebar supported for rotation at the front end of the frame for steering the bike, and a drive module configured to drive the rear wheel of the bike when operated selectively with power. The frame includes a down tube extending downward and rearward from the front end of the bike and a drive module enclosure formed at a second end of the down tube. The drive module enclosure defines a drive module receptacle that is open along the longitudinal direction of the bike. The drive module receptacle is sized to receive the drive module along the longitudinal direction of the bike.

A headset assembly system for a bicycle is provided having a handlebar stem (1), radially fastenable by tightening to a fork tube (2), rotatable by headset bearings (7) with respect to a head tube (3) wherein the headset bearings are fastened (7); a retaining flange (4), radially fastenable by tightening to the fork tube (2); a thrust ring (5), axially movable along the fork tube (2); such that the retaining flange (4) and the thrust ring (5) are configured to contact each other by a ramp (6) which relates a rotation with a movement relative to each other; the thrust ring (5) is arranged such that, when the thrust ring (5) is rotated around the fork tube (2) with the retaining flange (4) fastened to the fork tube (2), the thrust ring (5) moves with respect to the retaining flange (4) pushing the stem (1) against the headset bearings (7).

A stem includes a stem body, a column and a locking device. The stem body is provided with a perforation. The column is disposed at one end of the stem body and provided with a first aperture, the perforation is in communication with the first aperture. The locking device is disposed in the perforation and includes a clamping part, two sliding blocks and a first fixing member, the clamping part is located between the sliding blocks, and the first fixing member penetrates the clamping part and the sliding blocks. When the first fixing member moves toward the inside of the perforation, the first fixing member drives the sliding blocks to approach each other and squeeze the clamping part, such that the clamping part moves in a direction toward the first aperture. According to this, the assembly and disassembly procedures of the present invention are quite simple and easy to operate.

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.

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.
