How can I be a good Electric Bikes

Light , fast , flexible frame and so is one of the objectives pursued , in order to achieve this goal, each frame folding bicycle depends on the manufacturer's process . If the frame is designed according to the characteristics of the material strength and design , welding technology is mature . These have a direct impact on the appearance of the frame , the strength and elasticity. There are more important is painting, painting a good frame evenly and 3-4 layers of spray paint . Do not underestimate the paint, make the bike easy to maintain good paint , rust . If the frame does not meet the Electric Bikes above requirements to loading , then there may not be a straight line to produce a bike ride or difficult to turn , or will soon retire bike.

The frame is composed of what Folding electric bikes

Most iron frame , but the frame is divided into iron in the iron added to the other extreme frame chrome molybdenum Folding electric bikes steel, high strength steel , ordinary steel , etc. , after adding the other ingredients , for example can be made thinner pipe, makes the frame lighter overall . Recently, on the basis of the intensity is not reduced , there has been used a frame material other than iron , such as aluminum. Bicycle electric trike race to have carbon fiber material using titanium frame .

The importance of electric tricycle harness

Played a harness connected to the power brake and turn the role of the controller , it will cause a lot of problems of poor quality . As big line of fire , turn the brake failure, the car lost control and other serious problems. Why should lock wire bold ? Battery to lock and lock to the wire between the square of the controller is not enough, the wire will be hot , especially in the summer there will be lines melted skin , short Electric Bicycles circuit the fire . Since this section of the wire to form a longer resistance , not all of the current for the motor acting, a considerable part of the wire into a fever , so the car will appear boring and continued short trip mileage and so on. 9 , the relationship between electric tricycle brake , turn to the role and the harness can not brake controller choke off easily burn . Sometimes harness problems will make you suspect that the damage to the brake switch , such as switch between the connection to the controller , if the 5 volt line or Electric scooters signal line not General car does not go ; ground not General coaster ; brake lever to the controller harness between the signal line or the ground , such as disconnecting the brake failure. Brush motor damage type column : Brush masticate , copper head blown, copper head coke, copper head even burn , burn wire shorted shorted wire and shell , enameled blown, burned wires connected to the input , the input wire mill off .

Performance bike riding

Riding performance and structure about the size of a bicycle , the rider's body and the vehicle match each timber will be brisk ride , comfort and maneuverability . , And the vehicle body A, B, C3 -point contact , three points form a triangle whose sides and angles are important parameters of the bicycle. AB and AC 's length relationship to the rider can most effectively play physical . BC by the length and position of the rider and the vehicle may be customary , it determines the rider's cargo bike posture and comfort. Front and rear center distance L, fork and fork tilt angle θ T is also extending from the main parameters of a bicycle , according to the model selected . Generally , L, T and θ is greater value, the better the stability of the vehicle , from the straight running of the complex and strong , but the flexibility is poor; Conversely , L, a small value θ value T is large, the flexibility and stability of the vehicle of the hearing. L values ​​are based on the rider's body to select the material , generally 900 ~ 1200mm; θ value of 65 ° ~ 75 °; T value determined by the value of θ . Alice H of the fork is usually controlled at the center of the front wheel fork and the steering axis of the vertical position of the intersection J , J -point height from the womens mountain bikes ground is generally 15% to 60% of the radius R of the wheel . In addition, the manufacturing precision and wheel weight ( including tires ) also affects the riding performance.

Fault analysis of electric vehicles

( 1 ) insufficient tire pressure will increase tire friction and road surface , thereby reducing Continued mileage ; 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 point when stiff or tight spot , should be timely lubrication or adjustments. Lubrication general use butter , calcium or lithium grease ; Electric Bicycles adjustment , release fork lock master , rotating fork stop , when the handlebars turn the flexibility to meet the requirements , you can lock nut locking fork .
( 3 ) the flexibility of front and rear wheels turning bad , will increase the rotational friction, increase power consumption , thereby reducing Continued mileage . Therefore, once the fault should be timely lubrication and maintenance , lubrication general use butter , calcium or lithium grease ; If the shaft skin fails, you can replace the ball or shaft skin , if the electrical fault should go to a professional repair unit maintenance.
( 4 ) circuit inspection, turn on the power electric scooters switch , check the circuit is smooth, solid and reliable connectors are plugged , whether the fuse is working properly, especially connected with the output terminal of the battery cables are secure and reliable. Found fault should be immediately removed .
( 5 ) before the trip , check the battery charge , according to the judgment of the battery power is sufficient mileage to travel . If the power is not sufficient manpower should be supplemented by appropriate riding, avoid battery undervoltage work .
( 6 ) It should also be checked before traveling the working conditions of the motor. Starter motor and adjust its speed to observe and hear the motor running , if abnormal, should be timely maintenance.
( 7 ) should be checked electric lights, horn and other former bicycle use , especially at night travel. Headlights should be bright, light should generally fall in the range of 5-10 meters in front of the front ; horn should sound loud, not hoarse ; turning lights should be flashing normal , indicating normal steering , lights flicker frequency of 75-80 beats / min ; Meter display should be normal .
( 8 ) should be checked before traveling all the major fasteners are tightened , such as the horizontal tube , the riser, saddles, saddle tube , front, rear, bottom bracket , lock nut , pedal and other fasteners should not loose fasteners loose or fall off if there should be tightened or replaced promptly . The recommended torque fasteners generally: the horizontal pipe, the riser, saddles, saddle tube , front wheel , pedal to 18N.m, mother and rear wheels to lock axis 30N.m.

Transmission What are the benefits?

General use of bicycles in the city, in fact, there are many slopes in the city. For example, you can sometimes feel the pedal electric trike suddenly sink, with your eyes can not determine the slope often more. At this point, the role of transmission can be fully reflected, if there is transmission, it can be replaced at this time as long as the lighter gear to ease the ride. Of course, the same can be used when the wind. Advantage lies in the Three wheel bikes transmission, which can help you in case of physical prowess, effectively reducing your physical exertion. For example, when the cold, physical exertion is not too large, so I chose lighter than the number of teeth will be very easy if you ride when riding. When the female body as well as the poor, tired student exam, older persons can flexibly use speed bike. Therefore, the benefits of shifting the car really is too much.

Lighting,Electric folding Bikes

Lamps, lighting and instrumentation section is to provide a combination of electric vehicle display unit status . Instruments generally provide battery voltage display , vehicle speed display , riding status display, lighting status display. Intelligent instrument also displays fault Folding electric bikes the vehicle 's electrical components .
Common structure
Most electric bikes are using a hub motor direct drive front or rear wheel rotation . These wheel motor according to different output speeds , respectively, and with different wheel diameter wheels to drive the vehicle traveling at speeds up to 20km / h. Although these electric car styling and installation location of the battery varies, but the drive and control the presence of Three wheel bikes principles . Such electric bikes are electric vehicles mainstream .
Specially constructed electric bicycle
A small amount of electric vehicles using non- motor -driven wheel . These electric vehicles using side-mount or cylindrical motors, mid-mounted motor, tire friction motor . Generally use this motor -driven electric vehicles, which will be lower vehicle weight , the motor efficiency is lower than the hub -style efficiency. In the case of the same battery energy , the use of these motor vehicles are generally shorter than the 5% -10 % - wheel vehicle continues the course .

Round threaded screw within the fixed in the rear right side

Within the flywheel, the flywheel threaded screw fixed in the rear right side, keep the same level with sprocket, and through the chain and sprocket connected to constitute a bicycle drive system. From the structure can be divided into two types: single-stage flywheel and multilevel flywheel. Single-stage flywheel is also known as single wheel flywheel, mainly composed of coat, flat and retaining core one thousand jins, one Three wheel bikes jins, spring, washer, silk in several steel ball and other parts. The working principle of the single stage flywheel: when stepping forward move pedal, chain drive the flywheel rotation forward, while the flywheel gear and contains one thousand jins, flywheel rotating force to the core by one thousand jin, core drives the rear axle and rear wheel rotation, bicycle went forward. When to stop when the foot pedal, chain and coat are not rotating, but the rear wheels under the effect of inertia still turns forward core and one thousand pounds, while the flywheel gear produces relative sliding, thus to Cargo bike the core into the cartridge slot, one thousand kg and one thousand jins compressing the spring. When one thousand jins slide to the top of the flywheel internal tooth addendum, one thousand jins spring is compressed at most, a little bit forward slip again, one thousand jins are one thousand jins spring play, on the tooth root of "clicking" sound. Core rotate faster, one thousand jins also quickly in the flywheel gear sliding, "clicking" sound. When reverse step move down coat reverse rotation, will speed up one thousand jins of sliding, the "clicking" sound more urgent. Multilevel flywheel is an important part of bicycle transmission level flywheel is on the basis of single-stage flywheel, add a few slices of the flywheel, and in combination with the sprocket center axis, composed of a variety of different transmission ratio, which changed the speed of the bicycle.

The design method of bicycle

The world's first truly practical bicycle appeared in the early 19th century. In 1817, the germans DE les in Paris, France invented with the wooden two rounds of the bike. Bicycle came quickly Three wheel bikes the europeans preferred means of transportation. In the 19th century some europeans also conceive some ideal bicycle. Bicycle in the early stages of invention, people think that the greater the faster the speed of the wheel, two men riding a high wheel for almost one bike. In the invention of the bicycle phase, some people didn't take the bike before and after the two wheels electric trike into place, but the two wheels made placed around, the appearance of this kind of bicycle is similar to a wheelchair. This is early europeans design a tricycle. Tricycle balance better, easier for people to learn to ride a tricycle. As the bicycle technology improvement in the future, tricycle evolved into a kind of freight transport. It is also a tricycle, but designers put two momentum wheel in the front, a training wheels on the rear. When people is riding the bicycle in front can also do a passenger. This kind of bicycle with modern can bring people in the back of the bike design concept is just the opposite.

The old bike

Choose more old-fashioned 28 inches aggravating the bicycle. If a new car, before you set off must be running in 200 to 300 kilometers, to fully adjusted to hit the road again. So old, want to pass a comprehensive overhaul, especially for car seat for processing. Saddle shoulds not be too hard or too small, it is better to add a 3 to 5 cm thick sponge cushion. Notice must stay cushion surface drying and Cargo bike have fold and stitch seams, riding side for a long time not torn skin or long prickly heat. Saddle shoulds not be too high or too low to personal ride comfort is advisable. Handlebar should basically equals the seat height, height difference Three wheel bikes 3 to 5 cm as well. Should also be installed hanging bags before and after the bicycle frame. Backpack long distance cycling very tired and sick. Best should also install a kettle in the bicycle girder frame, so that may at any time convenient to take water in cycling. In addition, some bare agent was injected in the tyres, once a punctured tire, just pull out into objects, broken down hole air, can be automatically broken hole plug, pledged to continue riding. Before you leave, you must master to adjust and repair of bicycle, including; Tire repair, replacement, spoke, replacement brake block, rear axle in before the repair, adjust, repair the flywheel, etc.

The service life of the electric tricycle

1, the electric bicycle before use should adjust the height of the saddle and handlebar, 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 Cargo bike 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.
2, electric bicycle before use should check and adjust the brake before and after. Before the brake controlled by the right brake, the rear brake is controlled by the left brake. About brake Folding electric bikes 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.
3, electric bicycle before shall check the firmness of the chain. Chain too tight pedal bike in arduous, too loose is easy to vibrate, brush touch other parts. Chain of sag is suitable for 1 to 2 mm, usually don't have to pedal cycling can tighten appropriately. Chain adjustment, loosen the rear nut first, through the uniform precession spin out around the chain screw, adjust the chain firmness, retighten good rear wheel nut.
4, electric bicycle before use should check the lubrication condition of the chain. Handle and observe whether chain chain axis rotation is flexible, link corrosion is serious. If corrosion or rotation is not flexible, should include a moderate amount of lubricating oil, serious should replace the chain.
Before 5, electric bicycle riding, should check the tire pressure, handlebar front and rear wheels steering flexibility, rotational flexibility, circuit, battery power, motor working condition and lights, horn, fasteners, such as whether meet the requirements.

The electric tricycle maintenance measures

1, the first summer thunderstorm, ahead of prevention, cover poncho or in a shelter place, once out of the rain, try not to get wet battery and motor and other key parts; Because the electric car battery is the most afraid of water. Mild water just ventilated dry; If serious, you need to maintenance station.
2, recharge electric tricycle, try to Three wheel bikes easy to leak and heat dissipation, has reached the ideal charging effect; Feng jie vehicle industry warns customer, battery run in high temperature season, the main problems existed charge, increased temperature increases the activity of active material, fully violent reaction, the positive oxygen evolution potential and negative hydrogen evolution potential decline. So when charging reaction speed, charging current, charging need charging voltage is low. To prevent excessive charging voltage, should try to reduce the temperature of the battery, ensure good heat dissipation. Sun exposure makes the temperature in the electric trike has risen sharply, to bring the battery temperature rise, cause when charging the battery internal pressure increases with the increase water loss, which affects the service life of the battery.
3, should try to avoid the electric tricycle strong sunlight for a long time, lest make the inside of the controller components, caused by operating failure, there was an accident;
4, rainy days drive electric tricycle on the water surface, the water depth is less than the electric wheel center under normal driving, such as road water depth more than electric wheel center, will probably make the electric wheel water seepage and breakdowns, feng jie bike remind everybody must remember. Electric vehicles into the water is the most easily broken motor and controller, the citizens to pay special attention to water depth, in the case of no more than half electric wheel can run normally. Electric experts remind: encountered heavy rain, it is best not to ride electric vehicles.
5, summer should also avoid slamming on the brakes. Accelerates, especially start, should slowly turn the turn, sometimes can pause, to speed up the time to continue to accelerate. In the process of driving the car, should not be frequent starting, braking, in case of need to brake, can let go ahead to turn to, try to let the car drive by inertia.
