The fire safety of the tandem mobility scooters

Always check the circuit bike docking point, to prevent contact with the contact point is not strong to cause ignition, fever; avoid the aging, wear and tear caused by a short circuit, train electric scooters accident. Electric cars in normal use, failure to choose a professional service organization or person, do not disassemble electrical protection devices to ensure the protection of electrical circuits and equipment in good condition is valid. Electric bicycle battery will run out of flammable gas when charging, so that the charge must not narrow, sealed environment, should be in the outdoors, or remove the battery charge alone. To select the appropriate charging circuit, line laying should be fixed installation, to install short-circuit and leakage protection device.
Electric vehicle charging must be away from flammable items, can not charge too long, long charging time, the charger overheating easily lead to fires, shall be charged in accordance with the instructions when charging time principle, more than 10 hours . When charging, the charger should be placed in a relatively easy to heat the place; if battery electric bicycle inferior quality or prolonged use, the charger is easy to very high temperatures, causing a fire, so can not sleep at night time charging lightly.

In the process of moving electric bike started climbing when the pedal walker should prevent starting current is too large, mechanical overload of work for a long time, causing the motor coils, wires, batteries and governor overheating damage and even lead to disaster . To try to avoid the rain, roads and water to prevent water motor, charging the short circuit fire.
In addition, the purchase of an folding electric bikescar, should be preferred lithium bottle. Its capacity, since less consumption, less pollution, followed by lead-acid batteries dry, seal it, and not leak electrolyte, we must prevent the pollution caused by electrolyte leakage, corrosion and damage. Buy electric car to see the product specification must operate in accordance with the instructions, but also to choose the electric car, charger, motor models, specifications matching battery

The maintaince of the electric powered tricycles

To pay attention to cleanliness, especially in winter after saline water but also to promptly clean, otherwise easily cause corrosion of metal parts, paint aging off. Second, we should pay attention to the maximum height adjustable. After the new Juji period of time, in accordance with the requirements of the specification, check the adjustment to deal with the whole car. Then tightening and lubrication is essential. Check for loose fasteners, transmission parts are flexible, pay attention to the oil slick after the chain lubrication oil wipe a little oil to the flywheel point. To properly inflated tires, otherwise it will affect the riding comfort and durability. Brakes are essential to ensure the security, but should always check, if they find a problem should be adjusted or repaired immediately.
1, electric Mountainbikes should be adjusted prior to use good saddle and handlebar height to ensure riding comfort and reduce fatigue. Saddle and handlebar height should vary, saddle height is generally able to ride with one leg for a suitable and reliable (basic vehicle should remain upright), the height of the handlebars to the rider flat arm, shoulder and arms relaxed as appropriate. But the saddle and handlebar adjustment should first ensure that through the tube and the riser insertion depth must be higher than the safety mark lines.

2, before the use of electric bicycles should be checked and adjusted the front and rear brakes. The front brake controlled by the right gate, the gate by the left rear brake control. When the front and rear brake adjustments to the brake lever reach about half of the trip that is suitable for reliable braking; excessive wear of brake shoes should be replaced.
3, the first electric bike role should check the tightness of the chain. Chain too tight when riding pedal effort, too loose is easy to vibrate, collision other components. 1-2mm chain sag is more appropriate, can not properly tighten the pedals when riding in general. When the chain adjustment, loosen the rear wheel nut, through uniform spin precession around the tone chain screw, adjust the chain tightness, retighten good rear wheel nut.
4, electric bikes should be checked before the chain lubrication. Feel and observe the links of the chain axis of rotation is flexible, the link is severely corroded. If rust or rotation is not flexible, the right amount of lubricant should raise serious chain should be replaced.
5, before electric bike riding, you should check the tire pressure, steering handlebars flexibility, front and rear wheel rotation flexibility, circuit, battery power, the motor working conditions and lighting, speakers, fasteners and other requirements are met.
(1) insufficient tire pressure will increase tire friction and road surface, thus shortening continues the course; handlebar rotation flexibility will enable to reduce the impact of riding comfort and safety. Should be less pressure to replenish pressure, tire pressure should be in accordance with the provisions of the "electric bicycle manual" in the recommended tire pressure or surface pressure.
(2) handlebar rotation is not flexible, catching, when stiff points or tight spots, should be lubricated or adjustments. Lubrication general use butter, calcium-based or lithium-based grease; adjust, release fork lock nut, rotate the fork block, when the handlebar rotation flexibility to meet the requirements, you can lock the fork lock nut.
(3) the flexibility of front and rear wheels to rotate well, will increase the rotational friction, increased power consumption, thereby reducing the continued line mileage. Therefore, in case of failure should be lubricated and maintenance, lubrication is generally used butter, calcium-based or lithium-based grease; shaft skin if it is a fault, you can replace the ball or shaft skin, if the electrical fault should go to a professional maintenance unit maintenance.
(4) circuit inspection, turn on the power switch, check the circuit is smooth, solid and reliable connector is plugged in, whether the fuse is working properly, especially in connection with the output terminal of the battery cables are secure. Find fault should be immediately removed.
6. Do not use  adult electric tricycles zero start (ie standing start), especially in the weight-bearing and uphill should be prohibited. When starting, you should use human riding, when it reaches a certain speed and then converted to electric driving, or direct use of electricity to help move traffic. This is because the start-up, the motor must overcome the static friction force, when current is high, close to or even reach atropisomers current, so that the battery high currents, accelerated battery damage.
7, try to use human-assisted electric bike ride or power-assisted approach, especially uphill, load, haul or bumpy roads not usually have to help human riding. Thus, to avoid large current discharge the battery for a long time, damage to the battery, will help improve a charge to continue the mileage and prolong battery life.
8, electric bikes suited to rocky or too steep (generally & le; 8 & deg;) road. In case of such a road, the driver should slow or get off the implementation. In this kind of road travel, motors, controllers, batteries and other poor working conditions, will reduce the life and easily damaged.
9, the electric bicycle travel should avoid frequent braking and starting, the front brake or both should return to the governor, in
Electric Bicycle
Support of regional roads as much as possible the use of human riding. Thus, a large current to avoid damage to the battery when starting.
10, the standard load of 75 kg bike, should try to avoid overload. If overloading driving, you should use human riding, to help move the way human.
11, cold weather use of electric bicycles, should be human-assisted or electric assisted travel; and it should also pay attention to battery power and voltage indication, when cold weather in general, should be appropriate to reduce the depth of discharge of the battery, undervoltage condition must not travel. This is because, when the weather is cold battery charge capacity, discharge capacity were decreased.
12, the electric bike is not afraid of rain and snow. However, when the water level height can not exceed involving electric wheel chocks under the edge to prevent water damage to the motor. After rain and snow riding, you should wipe clean as soon as possible; if electrical parts flooding should be dried with a hair dryer. Avoid iron corrosion and leakage circuit, short circuit fault.
13, rain and snow riding, driving speed should be reduced, increasing the braking distance brakes attention to prevent skidding and turn around so as to avoid endangering persons.
14, electric bicycles should avoid prolonged sun exposure, should be stored in a cool place. Sunlight will accelerate the aging of the paint, plastic, rubber parts and electronic components, reducing its service life and reliability.
15, when the battery is charged with supporting or charger models specified by the manufacturer, can not be mixed; charging, the battery and charger should be located in the shade, safe place, away from flammable items, to avoid the heat, humidity and water washout prohibit the use of items covered by prohibiting contact with infants and young children. Charge should first make sure the grid voltage and frequency meet the requirements of the charger, then the battery and charger output connection, the charger is connected to the input of the grid; after charging is completed, disconnect the grid connection and then disconnect the charger and battery connection. Lead-acid batteries normally takes 6-8 hours.

The maintaince of the electric powered bicycles

Battery electric cars as transportation means of transport has been popular, it was discovered that every winter a large number of electric vehicle battery capacity has shrunk over the summer, or it becomes difficult to charge, and even fail to start. In fact, this is because many consumers ignoring the winter for battery maintenance. Reporters visited the capital of several  electric recumbent trike repair shop for electric car battery maintenance to understand.
Saihan an electric car repair shop maintenance staff, told reporters that the battery optimum working temperature of 15 degrees Celsius to 40 degrees Celsius. Outside this temperature range, it will affect the normal operation of the battery, the battery life will be shortened. A normal lead-acid battery can ensure that vehicles travel the farthest distance of 50 km, due to thermal expansion and contraction principle, the ambient temperature at -10 degrees Celsius, the battery power is not one hundred percent release, winter mileage than full power once the summer full power to reduce a lot of mileage. So for battery maintenance is very important.
First of all aspects of the charge after every home, regardless of the length of time, should be charged, to keep the battery at full power use state, if not the occasional little effect on the battery is fully charged, but often do not fully charged, the battery will produce a "memory" of the impact it continues the course, but also loss of battery life. First insert the battery charging plug, plug the power plug. Charging is completed, first pull the power plug, and then pull the battery plug.

Second, start the electric trike bicycles, avoid large current discharge, reduction manned exercise, when climbing or help implement the best human riding, otherwise a great damage to the battery. If a vehicle is parked in the open air or cold storage when not in use for several weeks, remove the battery and store in a warmer room, to prevent freezing damage to the battery. And when the temperature is too low to try to shorten the duration of use of electric vehicles, and should be promptly charged. If you do not plan to use in the winter car batteries, rechargeable batteries should not have been put to use during the coming year, and every one should be charged once a month to battery power, to ensure that the lead-acid battery storage capacity, while avoiding the acid spill damage battery. Maintenance staff, said maintenance charge the battery to remember to wash, more power.
Six months after use, it is best to do a battery maintenance service points, appropriate complementary battery electrolyte, the electrolyte adjusting the proportion of good and check deposit of electricity to keep the battery electrolyte specific gravity, if necessary, to increase the number of charges. Also, clean the battery terminals and apply special grease to protect is also important when it ensures effective and reliable electric car start, prolong battery life

Foreign standards of the folding tandem bicycle

As the global voice for sustainable development continues, green energy has become the theme of the times. Low-carbon, low travel tools become the darling of the new era of people around the world. Should the occasion, the rapid development of folding tandem bicycle vehicles, and soon swept the globe. To facilitate the management of the regions and countries of the folding electric trikes car has a different management and import standards, China as the most technologically advanced and largest regional exports, a comprehensive understanding of the various areas of electric vehicles defined standard is very important, in this writer for Solo part of the majority of manufacturers such as: electric cars standard parts of the United States, Japan and Taiwan.
First, the United States
The National Highway Traffic Safety Administration regulations, will be classified as low-speed electric bicycles consumer products, electric bicycles belonging to the Consumer Product Safety Commission (CPSC) jurisdiction. The US Consumer Product Safety Commission (CPSC) provides low-speed electric bicycle or tricycle manufactured for commercial use must be stepped pedal assembly, electric motor output not exceeding 750 W, speed most 20 miles (32 kilometers) per hour, and vehicle weight not exceeding 50 kg, compared to other countries, the United States to regulate and restrict electric bicycles can be said to be the most relaxed, but states are not the same for the definition and specification of electric bicycles.
Second, Japan
Japan's electric bicycle use and management adopted a strictly limited. Japan only allows "smart electric assisted bicycle" on the road, and "smart power-assisted bicycle" requirements established very strict rules,
Third, the EU
Electric bicycles in the EU are generally divided into two categories: namely, electric assisted bicycles and electric bicycles. The so-called do not need a driver's license can legally hit the road bike refers to the power-assisted bicycle, which limit the maximum power of 250 watts, the maximum speed of 25 km.
folding electric trikes Bicycle
European Standards Committee on April 30, 2009 officially announced the new electric assisted bicycle specification EPAC / EN15194, the content contains the relevant technical specifications and test procedures. The European standards within the meaning of the electric-assisted bicycle EPAC, its maximum continuous output power of 250 watts, traveling up to 25 kilometers per hour shall automatically power down, the use of the power system or device for 48VDC battery charger 230V input skill.

EPAC standard set out in E-bike's engine system, security specifications and test mode charging system circuit. New EPAC standard CEN standards are more complex than previously, the main contents of the tests have three major projects: EMC, safety and mechanical properties, which are compatible with the electromagnetic EMC standards through the most difficult. EMC standard is designed to allow the use of driving an electric vehicle drivers to get security, and to ensure that electronic components riding vehicles, not because the electromagnetic pulse generated by cell phones interfere with, in addition, a formal definition of electric bicycles for EPAC (Electrically Pedal Assisted Cycle.
The EU in January 2009 EN15194 test standard that would apply to the EU 30 countries: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland , Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, United Kingdom. Regulations Full name: EN15194: 2009 Cycles Electrically power assisted cycles-EPAC motor-assisted bicycle.
Fourth, Canada
Since 2001, Canada's federal security law requires a defined power-assisted bicycle (PABs) standards. It is defined as 500 watts powered two-wheeled or three-wheeled electric motor bike, and there is no electricity supply but also by the feet when stepping forward. In addition, under the regulatory safety requirements must be met up to 32 km, and the manufacturer must indicate told it was obvious at the bike in the body, but each province in Canada to require electric cars are not the same, are summarized below the relevant requirements of the provinces.
Fifth, Australia
The Australian Government's Vehicle Management Standards Act, all vehicles traveling on the road in the market before all must comply with Australian Design Rules (ADRs). Vehicles they cover include bicycle and electric assisted bicycle.
Six, India
In India, all electric vehicles must be certified by ARAI, the output power is less than 250W, and less than 25 kilometers per hour electric car easier to pass, while the larger horsepower electric cars need to pass legislation CMVR complete specification of the testing process, very time-consuming and expensive, and therefore the market for electric vehicles in India delay on track.
Seven, New Zealand
Motor vehicle output power less than 300W is classified as electric bicycles, bicycles must comply with the same specifications.
Eight Hong Kong
As Hong Kong is the implementation of "one country two systems", Hong Kong has a separate so the traffic laws, electric bicycle is considered a motorcycle in Hong Kong, with the same car must be vetted and approved by the Transportation Department to imports.

Chinese standard of electric bicycle

electric recumbent trike main four national standards: there must be a foot to achieve human riding; maximum design speed of not more than 20km / h; vehicle quality is not more than 40kg; motor output power less than 240w;
