The present invention relates to a bicycle with bicycle alarm. The bicycle includes a control unit for functional interaction with at least one subsystem of the bicycle. The control unit includes processing means, such as including a processing unit, for processing the at least one status signal, and output means for outputting at least one output signal. The bicycle further includes the at least one subsystem being arranged for providing at least one alarm status signal relating to the bicycle alarm as the at least one status signal, and the processing means are arranged for processing of the alarm status signal relating to the bicycle alarm and providing at least an alarm output signal as the at least one output signal. The alarm output signal is a signal for providing an alarm signal for an audible alarm, an alarm signal for a visible alarm and/or an alarm signal for distribution via a network connection, such as a network connection for short-range, a network connection for a local range, or a network connection via a cellular or mobile network.

A bicycle frame is discussed having a battery fully contained within a down tube of the bicycle frame. The battery may be inserted into or removed from the down tube via a through opening through a bottom bracket housing of the bicycle frame. Weakness in the bottom bracket housing due to the through opening may be compensated for, fully or partially, by utilizing a bottom bracket bearing assembly that has a structural component, or structural component assembly, that extends completely through the bottom bracket housing and removably couples to the bottom bracket housing.

An electric bicycle and a battery lift mechanism and a battery carrying device thereof are disclosed. The battery lift mechanism includes a bracket, a carrier for carrying a battery, an upward-force device coupling with the carrier, and a locking device selectively in an unlocked state or a locked state. The carrier is movable relative to the bracket along an up-down path; the upward-force device is capable of applying an upward force to the carrier. When the locking device is in the locked state, the locking device interferes with the battery to limit the relative movement between the battery and the bracket. When the locking device is in the unlocked state, the interference between the locking device and the battery is removed, so that the upward-force device drives the carrier carrying the battery to move upward relative to the bracket.

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.

A step-through type vehicle includes: a frame assembly; at least one front wheel and at least one rear wheel connected to the frame assembly and rotated by a power unit; and a plurality of portions comprising one or more flexible portions, and one or more fixed portions. The fixed portions include a front structure, a rear structure, and a top structure disposed between the front structure and the rear structure. The flexible portions include at least one retractable member. The top structure and the retractable member include a plurality of solar panels. The retractable member is detachably attached with the top structure, and is retracted upwardly towards the top structure, and stretched downwardly from the top structure towards the front wheel and the rear wheel. The retractable member is foldably stowed inside at least one box like compartment, which is at least one part of the rear structure.
