An china electric motorcycle is provided such that even if a power drive unit is mounted to swing arm, it is difficult for a load to be applied to wiring connected to the power drive unit. In an electric motorcycle in which a PDU and a running-purpose power-generating motor are attached to a swing arm turning around a pivot shaft, and electricity from batteries is supplied via a contactor box to the PDU, from which the electricity is supplied to a power-generating motor, torsional portions extending generally parallel to the pivot shaft are provided at a portion of output lines connecting the contactor box with the PDU so as to allow torsion to absorb swinging movement of the swing arm.

The utility model discloses an electric motorcycle with a gasoline electric power generator, which is composed of a motorcycle frame, wheels, a handle, a direct current motor, etc., wherein, the outer rotor of the direct current motor is arranged on a wheel hub, and a gasoline engine is used for driving a generator to supply electricity to the motor through a rectifier, or the electricity can be supplied to the motor by an accumulator through a pressure regulating (controlling) device, and thereby, the wheels are driven to run. When the gasoline engine is used for generating the electricity for the run, the utility model can be used for a high speed run in a long distance, the load carrying capacity can be improved, and meanwhile, the accumulator can be charged; when the accumulator is used for supplying the electricity for the run, the utility model can be used for the municipal run in a short distance, and the noise and waste gas pollution can be avoided.

The landscape of Tibetan grassland has experienced great changes in recent years.Some of them are visible, for example, fenced pastures, brick buildings, paved roads, vehicle tracks,electric wires, telephone towers, and so on.Some of them are invisible, for instance, nomads' attitude toward pastoralism and husbandry under the backdrop of market economy.The aim of this paper is to analyze the influences of technology on sociocultural changes in Tibetan nomadic area through two individual cases.In addition, the writer hopes to discuss some issues relate to technological studies in anthropological field.

The demands on internal combustion engines for low emissions and fuel consumption are increasing year by year. On the other hand, engines to be used in motorcycles need to provide high output and quick response to meet user desire. In order to realize low fuel consumption while keeping high performance, it is necessary to properly understand cyclic variations during combustion as well as the influence of the injection system on fuel control during transient periods.

In order to suppress the generation of greenhouse gases associated with the use of automobiles, hybrid cars and electric vehicles have been released and spreading in the world. About motorcycle, scooter type electric motorcycles have been sold. It is particularly widespread in China. However, in a motorcycle battery installation space is small, the range is short compared with electric vehicles, improvement of power saving and battery is important. The requirement for china electric motorcycle is the high efficiency motor operated in variable speeds. A permanent magnet motor can be operated at the rated power with high efficiency but efficiency is low at a high speed. In this paper, we present new techniques to improve the efficiency and propose the motor specification for electric motorcycles.

Research on travel behavior of the urban low-income citizens in China is minimal. The main objective of this study is to examine the travel characteristics and trip chain characteristics of China's urban low-income. Using the travel data collected in the city of (a prefecture-level city in east China), Two-Step Clustering Analysis is conducted to identify low-income people from the dataset. It is found that urban low-income people have lower mobility than the non-low-income. China electric motorcycle with gasoline electric power generator.They tend to make fewer trips and of shorter distance. However, average trip duration of the low-income is longer than that of the non-low-income. Results show that the low-income individual makes most of their trips for subsistence activities, such as going to work or school. In addition, large proportions of all trips made by the low-income are undertaken by walking, china electric motorcycle, and bicycle. The number of trip chain of low-income people is generally small, and the length of said trip chain is short. Finally policy implications are recommended in the context of providing transportation equity service to improve.

In recent years, with many cities limiting motorcycle-related regulations in China, Electric bicycles due to the inexpensive, easy to maneuver, energy saving and environmental protection, are used by people of all ages. Now, electric bicycles have become one of the main means of transport, back of electric bicycles as "child seat" to carry child travel commonplace, traffic accidents are also frequent. Through the widespread use of electric bicycle child seat from the safety and comfort of both analysis concluded: these structures a variety of seat provides safety and security for their children is very limited. Next child safety seat structure, strength, and to do in-depth research, quality standards and quality control methods.

Living in law, and law has a life. To live with "an eye of law" is the professional way of getting harmony with life and law. No Motorcycle and Electric Vehicles(NMEV) is temporary measure which bases on administrative usefulness in order to get instant effects. Italso cannot conform to specification of administrative rule of law and satisfy modern legaladministration. it cannot accord with idea of modern administrative rule of law and has nothingin common with the modern legal developmental orientation. It is difficult to see things as inscientific and reasonable administrative law, and it is different from the thinking model of modern service administration. Moreover, it cannot achieve theoretical breakthrough in the traditional foundation. It can only indulge traditional thinking model without theoreticalinnovation and development of modern rule of law and administrative rule of law.

Electromagnetic compatibility is an important environment index and safety index.The related authorities are studying and establishing the standard for anti-interference performance of motor vehicles.According to the test results,the anti-interference performance of Chinese motorcycles is very poor.The players in motorcycle industry should pay attention to the electromagnetic compatibility, aiming to improve the environment and safety performance of motorcycles made in China.

During an important period of the global advocation of environmental protection and low-carbon energy-saving, bicycles or electric motorcycles have been increasingly ridden.
