A fuel tank assembly for a motorcycle. The fuel tank assembly includes a fuel tank defining a fuel containment volume. The fuel tank has an upper wall. A fuel cap is operable to selectively open and close the fuel containment volume. A motorcycle accessory is attachable to the fuel tank via a connection structure including first and second connection portions that are complementary and inter-engageable together to positively define a fully-secured state. The first connection portion is secured to an exterior surface of the upper wall of the fuel tank, and the second connection portion is secured to the motorcycle accessory. The connection structure defines a finite position and rotational orientation of the motorcycle accessory upon relative rotation of the motorcycle accessory with respect to the fuel tank to the fully secured state.

A network-enabled bicycle comprising a bicycle frame and an electronic device mounted to said bicycle frame is provide. The electronic device of network-enabled bicycle is configured to communicating with other network-enabled bicycles and/or a server via a wireless network access point. In general, a set of network-enabled bicycles are equipped with respective electronic devices which are programmed for allowing the bicycles in the set of bicycles to exchange data directly or indirectly with each other and/or exchange data directly or indirectly with the server via one or more of the wireless network access points connected to the server through a data network. In accordance with one specific example of implementation, the network-enabled bicycle connects to the wireless network access point over an open Wi-Fi connection.

A mounting assembly for releasably securing a radio handset microphone to a motorcycle handlebar is provided. The mounting assembly includes a bracket element to extend partially around a motorcycle handlebar and a rigid plate extending from the bracket element. The bracket element is adapted to be joined to the motorcycle handlebar such that the bracket element partially surrounds the motorcycle handlebar. The rigid plate includes a mounting surface for mounting a radio handset microphone thereto. The mounting surface generally extends over the handlebar and is easily accessible to the motorcycle occupant. The mounting assembly may be combined with a carrier and a handset adapter to provide a mounting system with a secure landing zone that firmly holds the radio handset microphone in place.

A fluid containment system that comprises a fluid container with a top, with an orifice and a wall extending from the bottom, a junction cap that can be mechanically attached to the extended wall, a tube leading from the junction cap, and a mouth piece attached distal to the junction on the tube suitable for an end user to draw fluid from the fluid container.

An optical sensor disposition structure of a saddle riding vehicle includes an optical sensor, left and right handle bar grips installed on both side portions of a handle bar pipe, and a switch case installed between the left and right handle bar grips and supported by the handle bar pipe, and the optical sensor is installed on the switch case.

Disclosed is a smartpack device detachably attached to chassis of a bike. The bike includes peripheral electrical devices. The smartpack device includes a housing, a separating assembly, a locking unit, plurality of indication units, a battery unit, a door, a computer and a battery unit to power the peripheral electrical devices of the bike, computer and plurality of indication units. The plurality of indication units is configured on the housing to emit light to indicate status of each peripheral electric device of the bike. The door connected to the housing to allow access to the battery. The computer is configured on the housing includes a memory unit to store plurality of modules, a touch display unit to display processed plurality of modules and to receive touch commands from a user to access the plurality of modules and the processing unit to process the plurality of modules and is coupled to the memory unit. The plurality of modules includes a navigation module to display navigation route information on the touch display unit, and a control module controls at least one of plurality of indication units to indicate status of the electrical peripheral devices on receiving commands through touch display unit.

A dynamic training system provides elevated load and energy demand on a rider of a moving bicycle out on the road or track. Resistance to movement of the bicycle is provided by a resistance unit which may include an eddy current brake. A processor may generate a control signal that adjusts the resistance to replicate the effort of riding a predetermined course or training protocol. Multiple riders at different times or locations can compete on a common virtual course. A stronger rider can be restrained by a heavier imposed load to keep pace together with a weaker rider, without compromising total power expenditure to keep the riders together.

A shock-absorbing front fork assembly of a motorcycle includes a front fork, a pressure buffering cylinder and a control valve disposed between the front fork and the pressure buffering cylinder and electrically connected with a brake system to control the communication between the front fork and the pressure buffering cylinder according to the operation of the brake system. When the brake system is not actuated, the control valve is open to make the front fork communicate with the pressure buffering cylinder, thereby making the spring supporting force relatively smaller. When the brake system is actuated, the control valve is close to make the front fork not communicate with the pressure buffering cylinder, thereby making the spring supporting force relatively larger. Therefore, the spring supporting force is adjusted by the brake operation, that raises the riding comfort and safety.
