Where can I get it, or Jiaozhou, Jiaonan, where there are aluminium profiles? You'd better leave me a call... And do you have any training places for Thai engraving software?.
There are three kindsThe driving current of motor and the phase speed regulation of multiphase motorUse mechanical transmission, use external transmission, internal transmissionThere are automatic transmission abroad, through the detection of the movement cycle of spokes, in the 5 battery energy, through the diameter of 2 cm small motor to change the mechanical transmission ratio.Process manufacturing process Aluminum Alloy bicycle rimYou don't lose money.Others do well, how can you grab the meal?The market is too small.Is extrusion aluminum section, to batch processing, to open the mold, China's poor performance of aluminum, can not do high-grade racing, big aircraft. The 500 thousand yuan is not enough for the first shipment.The profiles are cut off, then rolled in several rounds, protected by carbon dioxide gas.Drill spoke hole. You don't lose money.Have imported aluminum, import production lines, tens of millions of yuan bar, made in China is a special equipment, you can do it yourself, if commissioned by others to design and manufacture, absolutely compensate for death.
What is the most portable electric bicycle brand, type, price, what store sale?It is produced in Beijing, Beijing Shenzhou giant new energy technology Co., Ltd., the factory mainly produces power type lithium batteries, with one of the smallest skillful bicycles, super lightweight, aluminum alloy body,The price is 3000 yuan, and the battery part is 1500 yuan. The battery is in the middle of the bicycle cross bar, and it is inside the cross bar. You can run 15 kilometers at a time, about 10 amperes per hour, and 24 volts.

Design, scooters and electric vehicles structure, technology and engineering, the difficulty of safety is different, can not be confused together, here is their distinction;
What are the disadvantages of using electric bicycle?For chemical two power supply, the charging time is longer, the charge current is smaller, the battery charge discharge cycle is higher, popularly speaking, is the battery life long.What kind of bike is the most labor-saving and fast?Type 700 tires, 27 inch wheel diameter km racing is the best effort, but the strength of car tires will be low, embeds the groove their spokes pierced with two holes, this is a rule, every time just two, not too much; they cannot run on bumpy roads, not equipped with others.There is a price of 600 yuan / vehicle, bearing material difference, the normal price is 3000 yuan / vehicle, at least Taiwan bearings.With Japanese production generally suggest that smuggled in second-hand bicycles, is generally 300 yuan / vehicles to 500 yuan / vehicles, 24 inch, 26 inch, 1 inch and 3/8 section of ordinary tire can, very suitable for long-distance riding, such as send tickets, send pictures, send express salesman, home appliance
