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.

A lock system for securing a battery of a vehicle operable by muscle power and/or motor power, in particular an electric bicycle. The lock system includes: a deadbolt which is pivotable about a bolt axis, a lock cylinder which is configured to actuate the deadbolt, and a lifting element which is coupled to the lock cylinder, the lock cylinder being movable into a holding position and into a release position, the lock cylinder in the holding position preventing a removal of the battery in a removal direction, and in the release position allowing the removal of the battery. The lifting element is configured to move the battery in the removal direction when the deadbolt is moved from the holding position into the release position.

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.

A tiltable vehicle is configured to transform between an autonomous mode and a rideable mode by pivoting the handlebars and steering column of the vehicle about a pitch axis. In the autonomous mode, the steering column is folded back toward the chassis and a tiltable chassis of the vehicle is prevented from tilting. In the rideable mode, the steering column is unfolded and the chassis is free to tilt. In some examples, a tiltable vehicle includes features beneficial for vehicle-sharing, such as parking devices or a basket. These features may be included on any suitable vehicle and are not limited to use on transforming vehicles.

A motorcycle, or saddle type vehicle, is disclosed that may have at least one seat and at least two wheels, at least one hub electric motor. A large dry storage compartment may be positioned between the rider and steering mount. A rechargeable battery and battery management system may be located below the storage compartment in a battery housing, where the battery housing may be a structural component of the chassis. A rear electronics housing may be attached to and located behind the battery housing, and may contain major electrical components such as electric motor controller and contactors. Two structural members, or frame side rails, may form sides of the storage compartment and extend between the electronics housing and steering mount. The electronics housing may also connect to the battery housing such that the battery housing reinforces and strengthens the chassis, or structural frame.

An auto-balancing transportation device having a compact form. Left and right foot platform sections are coupled for fore-aft tilt angle movement relative to one another. Left and right wheels are provided under the respective foot platforms. With a rider's weight directed primarily downward onto the wheels and not onto the coupling structure, the coupling structure may have sufficient space to house the battery. In addition, more efficient and lighter weight supports and bearing arrangements may be used in the coupling structure. Various embodiments are disclosed.
