The present utility model discloses a two wheel electric motorized cycle frame incorporating a case-free battery, including a frame main body with a battery containment framework disposed on the frame main body. The battery is contained by the battery containment framework. At least one side of the framework is removable to facilitate replacing the battery, and partition boards are inserted in the framework to separate out a protective cavity for electrical connections. According to the present utility model, the battery is placed in the battery containment framework, so that a battery case is omitted. The battery is safely fixed in the framework, and one side of the framework is removable to facilitate replacing the battery. Furthermore, the partition boards are disposed in the framework to separate out the protective cavity for electrical connections of battery cables, thereby solving the problem that the battery cables are exposed to the outside and cannot be effectively accommodated due to replacement of an enclosed battery case with an open framework.

Embodiments disclosed herein include an electric assist bicycle adapted for a both personal and public use, and subcomponents of the bicycle. The electric assist bicycle can include a hollow frame with one or more cables routed within the hollow frame. The hollow frame can be configured with an internal battery compartment. The electric assist bicycle can further include a modular electronic locking system.

A vehicle has a driver module and a propulsion module selectively connected to the driver module. The modules are separable from each other as independent units. The driver module has a driver module frame, at least one front wheel operatively connected to the driver module frame, at least one front suspension assembly operatively connecting the at least one front wheel to the driver module frame, and a seat connected to the frame. The propulsion module has a propulsion module frame, at least one rear wheel operatively connected to the propulsion module frame, at least one rear suspension assembly operatively connecting the at least one rear wheel to the propulsion module frame, a motor operatively connected to the at least one rear wheel, and an energy storage device operatively connected to the motor.

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.

An ATV is shown having a radiator that is coupled to the frame forward of and a hood is rotatably coupled to the frame and having an open position providing access to the radiator and a closed position enclosing the radiator.

The present invention relates to a bicycle with connector function and at least a number of subsystems. The bicycle includes a tube assembly including a frame with mutually fixed tube elements and movable tube elements, such as a steering pin and a handlebar, at least a first bicycle cassette, for holding at least a first of the number of subsystems, such as a bicycle control unit, of the bicycle for providing a respective function to the bicycle. The first bicycle cassette is arrangeable in at least a first tube element of the tube assembly, and includes a first cassette contact, including a number of contact poles, that is connectable with the at least first of the number of subsystems internal in the first bicycle cassette. A bicycle also includes a connector for connecting with the first cassette contact of the first bicycle cassette. The bicycle connector includes a first connector contact, including a number of contact poles, for connecting with the first cassette contact, and at least one output contact for connecting with a respective subsystem. The bicycle connector is arrangeable in the respective first tube element of the tube assembly.
