Electric bicycle to further improve the efficiency of energy use electric bikes

d microelectronics technology in three wheel electric tricycle in the process of product design, mold processing and production, constantly improve the production and improve the production process automation technology. Electric bicycle production enterprise and national institutes, colleges and universities cooperation, system upgrading of the technological content of products, the formation of technology and products with independent intellectual property rights, continue to stay ahead in the field of the techniques of electric bicycles in the world. Four national standards for electric bicycle is the most main: there must be a foot can realize human cycling; The highest design speed is not more than 20 km/h; The mass is not more than 40 kg; Motor output power is not more than 240 w.European standards committee on April 30, 2009 formally announced new electric auxiliary EPAC/EN15194 bicycle specification, content contains the relevant technical specifications and test procedures. Referred to in this European standard electric assist bicycle

EPAC, the highest output power 250 w, driving speed of 25 km to the power, the use of electric power system of 48 VDC batteries or device 230 v input power charger. Flyhorse electric folding bikes should be adjusted before use saddle and handlebar height, to ensure the comfort of riding, relieve fatigue. Saddle and handlebar height should vary from person to person, usually the height of the saddle for the rider to reliable landing on one foot for appropriate (the vehicle should be the basic upright), the height of the handlebars to rider forearm flat, shoulder and arm relaxed as appropriate. But the adjustment of the saddle and handlebar should first ensure tube and the insertion depth must be higher than the safety sign of the stand pipe line. Electric bicycles should check and adjust the brake before and after before use. Before the brake controlled by the right brake, the rear brake is controlled by the left brake. About brake before and after the adjustment to the brake handle their half of the trip to reliable braking is suitable; Brake skin excessive wear, to timely replacement.
