Hyundai IONIQ electric kick scooter showed in 2017 CES

Hyundai displayed a IONIQ autopilot electric vehicle in CES 2017, at the same time there is an IONIQ electric kick scooter, to help users solve the last mile of a trip.

IONIQ electric kick scooter is the best partner of electric vehicles, this electric kick scooter designed to work with the IONIQ electric vehicle, while not in usage it can be placed in the front door for charging. Of course, this also means that Hyundai may not sell this scooter separately , However this is just a concept product, more details have yet to be officially announced later.

IONIQ electric kick scooter with folding design, so it is very convenient for portable. In addition, it equipped a headlight and tail light,and the digital instrument panel can show the real time speed, power and mileage. 12 miles per hour speed is quite enough for the urban shuttle , after all, it is a good choice for commuters.

Interestingly, the user can directly adjust the scooter speed through the “thumb switch”, such as sliding up means acceleration, decline to slow down or by pressing the plate brake on the rear wheel.

Unfortunately, Hyundai has not released maximum driving mileage of this electric kick scooter, listing date and price are unclear too.

Why the unicycle balance scooter will not fall down?

For the Chinese consumers, the first time to know about the electric balance scooter may dates back to the 2008 Olympic Games. At that time, the guards in the Olympic gym were riding on the electric balance scooter provided by American balance scooter manufacturer-Segway Inc, as a means of patrolling. But the balance scooter was the new darling attached with “military” and “import” etc tags, so many people stop looking at this new gadget, and self balance scooters are always cast a layer of mystery. Today we would like to explore the scientific principles behind the balance scooter with everyone.

The working principle of the unicycle (single wheel) balance scooter

Unicycle balance scooter

Why unicycle balance scooter will not fall down ?

On one hand it is due to people can adjust their body gravity and the balance scooter moving direction , the change of moving direction of the scooter will balance the gravity of the rollover moment due to inertia .There is also an important point is that high speed rotating wheel has a large angular momentum which can resist the external torque, same like the top does not fall. In university physics, this phenomenon is called precession, and the autobiographical body rotates the direction of the external moment by 90 degree,while here the wheel turns the rollover torque into the “steering torque”.

motor improve the scooter balance

On this basis, the self balancing electric unicycle scooter improved to be driven by the motor, use the gyroscopes and circuit board for controlling to ensure the scooter will not fall.The body can be tilted forward to start,speed is controlled by the degree of body tilt, If you want to speed up just lean forward, slow down during backward. Overing the active control, to ensure the normal working of single wheel balance scooter,the acceleration sensor and angular velocity sensor (gyroscope) can’t be separated.

Accelerometer

The acceleration sensor can measure the acceleration caused by the gravitational force of the earth or the movement of the object,when measuring the acceleration value in one direction, we can compute the inclination of the scooter. For example, using acceleration signal in X axis, when the scooter is upright, acceleration will be fixed in X axis direction,and the output signal will be zero bias voltage signal. When the car is tilted, the acceleration of gravity g will form the acceleration component in the X axis direction, causing the output signal changes of the axis.But in the actual scooter running process, the acceleration signal produced by the motion of the balancing scooter itself will produce a large interference signal superimposed on the above mentioned measurement signal, so that the output signal can not accurately reflect the inclination of the true tilt angle. Therefore, the attitude information required for the upright control can not be completely obtained by acceleration sensor.

Angular speed sensor

Gyroscope can be used to measure the angular speed of the object. Balancing scooter installed with the gyroscope, you can measure the angular speed of the scooter, after integral processing on the angular speed signal,the scooter tilt can be obtained.

Core components of balance scooter

When it comes to balance,we have to talk about gyroscopes, the principle of gyroscopes is that the direction of the rotation axis of a rotating object will not change if do not affected by external forces.With this principle, something created to maintain direction was called gyroscope.It is also the principle when we riding a bike.

top

The quicker the wheels rotated the harder it can be fall down, because the axle has a level of power to maintain horizon. So once the unicycle balance scooter was running, it won’t fall down.

UL2272 approved 9 inch SUV hoverboard

Hoverboards happened to be an growing fixture around the roads just for more than a year, recording people’s imaginations and fulfilling the conjecture produced in “Back To The Future II”. Regrettably, hoverboards happen to be the topic of debate, as batteries have caught fire as well as explosion. We wish to introduce a UL2272 approved fire free 9 inch SUV hoverboard that can even ride on the sand beach to consumers.

This Sports utility vehicle hoverboard, with large format monster truck style wheels created for outside experience on snow, hard roads, riverbanks, and much more. The tires have deep lugs to supply traction and wick away dirt in the most difficult conditions.

This latest Sports utility vehicle hoverboard features 9 inch wheels, front led lights, rear turn signal lights and Bluetooth speaker. It utilizes mobile control application to supply users with the ultimate driving experience.

Other hoverboard brands offer similar hoverboards but none of them is UL2272 certified. The 9 inch Sports utility vehicle hoverboard may be the first 9 inch wheel hoverboard with UL certification. We feel this is really essential, because Sports utility vehicle hoverboarding is going to be much more challenging, therefore the hoverboards have to be much more robust to resist punishment that may happened with the truly amazing outdoors.

Self balance scooter history and its development in China

Self balancing scooter was born in early 2000s, the first brand name for self balancing scooter was created by Segway, it has been innovated by Dean Carmen Deka and also the large medical equipment maker Manley,they have been cooperated to introduce the computerized self balancing scooter. Today, they are the primary manufacture of electric balance scooters, well, but only in the United States.

Even though the electric self balancing scooter has a long histroy in production and design, Segway has recoginized as a brand name, for several reasons mainly because of its high cost, the development of Segway electric balance scooter isn’t smooth.However, after it spread into China, Chinese self balancing scooter has manufacturing them according to their cheaper labor cost, rich experience in manufacturer, thus they have made the self balancing scooter price a breakthrough.

Currently,they are many self balancing scooter brand appear in China market,include Koowheel, Ninebot,Chic,Freeman,CXM,Feating etc,their prices slightly different as their features not the same,they are occupy the main share of Chinese self balance scooter market.

Although foreign brands has got the advantages in technology and style, domestic brands is also good in design and production, without prejudice towards the scooter performance and safety, and reduced costs, china consumers are able to afford for these brands self balancing scooter.

Becoming the marketplace mechanism, with increased superior quality of self balance scooter,they would won more favor from China and around the world.In my opinion with China’s outstanding efforts, Chinese hoverboard manufacturer would have a brilliant future in the internation electric vehicle market.

Hoverseat:turn your hoverboard into a electric wheel chair in 1 minute

Hoverboard ( also being called smart balance scooter, smart balance wheel etc ) is now a popular gadget, with this kind of hoverboard people just change their body angle, the hoverboard will move forward or backward based on the tilt direction. As long as everything is working properly, the driver will not have the possibility to fall down.

But it can only be popular in the circle of young people, the elderly or people lack of balance sense may not easily dare to try. So some people do a simple modification to the smart electric balancing scooter with the installation of a hoverSeat, So that the original hoverboard which can only stand to drive, instantly turned to a electric wheel chair which provide a comfortable and secure ride experience Hoverseat for 6.5 inch , 8 inch and 10 inch hoverboard

The hoverSeat weighs only 5 Kg, made from aluminum alloy, consist of two parts: the bottom bracket and seat, it can be connected to the smart electric balance hoverboard with a lock,the entire assembly process takes less than 1 minute.

After installation is completed, using method is also very simple,with your two feet you can control the smart electric balance scooter in all directions for free movement, including backwards. Electric wheel chairs can travel in the plains, grass, gravel roads and sand.

In addition to being used as a vehicle, the electric wheel chair can be used to fetch goods, such as mobile refrigerators with wheels, luggage etc.

Balance scooter or electric kick scooter: which is more suitable for you ?

In order to meet people’s short distance travel needs, more and more types of transportation vehicle appear in people’s lives, such as electric motorcycles, folding electric bicycle, electric kick scooter, self balancing scooter and other new products, and in these means of transportation vehicle , electric kick scooters and self balancing scooter has become the hottest products, but consumers are often stuck in the purchase between the two scooters, do not know to choose electric kick scooters or self balancing scooter, today we would like to Talk about topic of which one to choose among electric kick scooters and self balancing scooters.

Product principle and price comparison:

Electric kick scooter is designed base on the traditional kick scooters, in the human labor powered scooter basis,they just add the batteries, motors, lights, dashboards, computer chips and other components, while the wheels, brakes, scooter frame and other systems has been upgraded too, from which the electric kick scooters generated. Generally it used more in daily life travel, especially welcome by the office workers. At present, the price of electric kick scooters from 150$ to 1000$ range, they are very popular with young groups in bigs cities among developed countries such as Europe and the United Sates.

Self balancing scooter, also well known as electric balance scooter, hoverboard, segway scooter etc, with single wheel and two wheels types. self balancing scooter is a new vehicle appeared in recent years, with battery powered motor, computer chip plus sensor to help control , it can use the scooter’s gyroscope and acceleration sensor to real-time monitoring of body posture changes, and make adjustments to achieve “dynamic” stability, it is used as a modern means of transport, leisure and entertainment. In addition to daily transport, in some exhibitions are often play their roles in the means of transport. The current price generally range from 100$ to 500$.

Performance comparison:

1. Portability

Electric kick scooter consist of the scooter frame, wheels, battery, brake systems, lighting systems, instrument panels and other components, a 36V 8A lithium battery powered light electric kick scooter net weight only about 12 kg, folding length is generally not more than 1.2 meters, with a height of not more than 50 cm, can be portable and also can be placed in the trunk.

Self balancing scooter consist of the tyres, pedals, motors, battery, brakes and other electronic components, a 72v 2A Lithium battery power unicycle balance scooter weighs about 15 kg, its dimension similar to a small car tires.

Overall, the self balancing scooter is slightly heavier in weight, although the balance scooter requires manual handling if power off, but the installation of carrying rod to the self balancing scooter is a better solution to this problem.

2. Climbing Ability

Self balancing scooter wheel size can reach more than 12 inches, able to adapt to many types of road conditions.

Electric kick scooter tire size generally does not exceed 10 inches, dealing with the general urban road is still relatively easy, but when situation encountered poor road conditions they are more difficult.

3. Security

Electric kick scooters and self balancing scooter both belongs to non motor vehicles without any additional safety devices,only allowed to drive in slow speed in the non-motorized road in theory,strictly use in accordance with the design speed will create a safer and more convenient travel experience.

Function Comparison:

Loading capacity

Self balancing scooter and electric kick scooter loading capacity difference is not very large, but as the electric kick scooter pedal is more spacious, is able to carry two people some times, so the carrying capacity, the electric kick scooter is relatively more advantage.

2. Endurance

Electric kick scooters designed considering the frequency of short-range usage higher, along with the highest speed and difference for driving, electric kick scooter driving mileage is usually better than the self balancing scooter with the same capacity battery, the longer driving mileage is, the electric kick scooter Or balanced scooter will increase the corresponding weight, at this point, the two are more consistent.

3. Driving difficulty

Electric kick scooters are driven in a manner similar to electric bikes, and they are superior to electric bikes in terms of station ability and are easier to handle.Self balancing scooter itself does not have control devices, only rely on the computer’s self balancing function and the driver’s intention . Although the self balancing scooter driving method more fashionable, and it is easy to learn, but if you want very precise control still needs some time to practice.

4. Speed
Electric kick scooters acceleration and braking devices can be manually controlled, more direct control, so a reasonable speed can be higher, but for safety reasons, the electric kick scooter speed 25km/H is more appropriate, exceed this speed is prone to dangerous situations.
Self balancing scooter although theoretically can achieve a wider speed, but based on security considerations, manufacturers will usually control its speed within 20km/h range(mostly are within 12-15km/h).
Summary:Electric kick scooters and self balancing scooters as two different types of portable means of transport, positioning in the function is also very similar, which is the main reason we bring here for comparison. Second, in actual use, these two products in the portability, endurance are not obvious,self balancing scooter is more dominant than electric kick in climbing ability, and electric kick scooters in loading capacity and driving speed are superior to the self balancing scooter. Consumers should choose according to their actual usage, if it used as a city travel tool, the two don’t have too much difference, whether it is electric kick scooter or self balancing scooter can be a choice, if you want to use as a short distance means of transport , electric kick Scooter is more convenient, while more functional and practical.

Smart balance hoverboard:you can riding it at home

Want to ride, but bad weather makes it not convenient to go out, or don’t have so many time, or a guest is about to visit you at home, and so on.Should you just hold on the impulse to have a ride? In fact, as long as there is a balance hoverboard, you can achieve the dream of riding indoor.

The reason to be able to ride indoor, because the smart balance hoverboard ( same as smart balance scooter or smart balance wheel ) is very small, whether it is single wheel hoverobard or two wheels hoverboard,completely no problem riding in a limited interior space. At the same time, it is powered by electric energy, there will not be any emissions; the high quality motors will not have lound noise in riding, will not affect other’s life or work indoor.

Smart balance hoverboard riding method is also unique, it can completely hands free, relying on the body gravity to control, when your body gravity in front, it will move forward,moving backward with the same theory. Such a body shift is minor, skilled riding make this like a general manipulation of the idea with hands free. Taking into account the difficulty of learning, some balance scooter manufacturers also introduced multi functional balanced scooter which can riding in both standing and sitting posture, so learning to ride can be easier.

Although the smart balance hoverboard is driven by electricity, do not means riding it is no fitness effect. According to related survey, standing ride a balance scooter, straight for 30 minutes, the average calorie consumption is about 285 carol , while S shape driving around the pile 30 minutes the average calorie consumption is about 900 carols, which means it is entirely possible to maintain body figure riding a hoverboard. At the same time, riding a balanced hoverboard, can also help to relax shoulders and spine, which is ideal for office workers.

Want to experience at home or in the office can also enjoy the fun of riding it? So let the smart balance car to achieve it for you.

How to maintain electric bicycles ?

First pay attention to clean, clean the water especially the winter salt water (many cities in the winter spray salt spray to avoid freezing after the snow ) in time, or it may easily lead to corrosion of metal parts, film aging and take off. Second,pay attention to the maximum adjustable height. After riding new electric bicycle for some time, user should check and adjust the whole electric bicycle in accordance with requirements of user manual,fastening and lubrication is essential. Check whether the fasteners are loose, transmission parts are flexible, please notice that after drip the lubrication oil to the
chain you should wipe the oil slick, flywheel drip only a little lubrication oil is ok. Tires inflated with appropriate air, otherwise it will affect the riding comfort and bicycle life. Brake is the basic guarantee forsafety, should be checked at any time, as long as problems are found should be adjusted or repaired immediately.

1.saddle and handlebar height of electric bicycles should be adjusted before use to ensure the riding comfort and reduce fatigue.
2.the front and rear brake of electric bike should be checked and adjusted before use.Front and rear brake adjustment subject to half press the brakes can do reliable braking, excessive wear brake pad should be replaced.
3.tightness of the electric bicycle chain should be checked before driving,appropriate chain sag is 1-2mm, generally you can adjusting the chain to slightly tight if no pedal riding .
4.the chain lubrication conditions should be checked before riding.If the corrosion or rotation is not flexible, right amount of lubrication oil should be added,chain should be replaced if with serious problem.
5.you should check the tire pressure, steering handle flexibility, front and rear wheel rotation flexibility, circuit, battery power, motor working conditions and lighting, speakers, fasteners etc before riding a electric bicycle,to see if they meet driving requirements.
6.try not to use zero start for electric bicycle(riding the electric bicycle without any pedal working), zero start should be banned especially in heavy load and uphills. For start up, you should first use the human ride, when it reaches a certain speed then converted to electric driving mode, or direct use electric assistant driving mode.
7. electric bicycles are not suited to rough road or sharp slope. In case of such a road, should driving slowly or get off the electric bicycle.
8. electric bicycles should be avoided frequent braking and start when driving, before or during the brake the speed control(throttle) should be turned back.
9. the standard electric bicycle load is 75 kg, user should try to avoid overloading. If overloading, should adopt the human ride or human assisted riding mode.
10.using the electric bicycles in cold weather,human assisted driving should be adopted; and user should also pay attention to battery power and voltage indication, should appropriate reduce the discharge depth, should not driving under low battery pressure.
11.electric bicycles can be driven in rain and snow weather. However, when crossing the water, the water level should not exceed the electric wheel hub bearing lower edge to prevent damage to the motor caused by water. Rain and snow days after riding, water should be wiped clean as soon as possible; if the electrical parts soaked with water, it should be dried with a hair dryer. So as to avoid corrosion of iron and circuit leakage and other failures.
12.riding in rainny and snow weather, the driving speed should be reduced appropriately,during brake should pay attention to increase the braking distance, to prevent skidding so as not to endanger personal safety.
13. electric bicycles should avoid prolonged exposure to sunlight, should be stored in the shade.
14. the battery should used supported charger or the manufacturer specified models; during charging, the battery and charger should be placed in a cool place, well placed, should stay away from inflammable and explosive materials;avoid heat, moisture and water;prohibited to be covered by itemscovered, prohibition of infant and child contact. Before charging user should first confirm if the grid voltage and frequency in line with the requirements of the charger, and then connect the battery with charger output port, the charger input port connect with power grid; after charging is completed, first disconnect the grid connection and then disconnect charger and battery connection. Lead acid battery charging normally takes 6-8 hours.
15.user should stop usage of the battery if low battery voltage, and charging as soon as possible, prohibit the battery in deep discharge and over discharge conditions,better the battery is always in abundance state. We recommend charging at least once a day.
16. battery should be stored in the cold, moderate air humidity place, the battery should be kept upright; before long time storage should fully charged and should regularly add electricity, then general charge once a month. Lead acid battery storage for a long time, you can add a few drops of distilled water to offset the evaporation of water to reduce the curing of the plate.
17. for initially use of electric bicycles,user should carefully read user manual to understand the performance of electric bicycles. Do not lend to people who do not know how to operate electric bikes.
18. mental patients, alcoholics and other inappropriate should be disabled to ride electric bikes; user with heart disease, epilepsy, and color blindness etc. should be careful when riding.
19. electric bicycles belongs to non-motorized vehicle, riding should comply with traffic rules, in the non-motorized lanes or local driving lanes.
20. electric bicycles should be stored in a place with cool, ventilated, dry, away from corrosive liquids and gases conditions; storage with vehicle upright and enough tire pressure; bicycle frame should not be loaded with heavy objects; and the battery should be stored separately.

Road policy for hoverboards in different countries

National Bicycle and Electric Bicycle Inspection Center experts said that the hoverboard ( same as balance scooter in this article)can be divided into two kinds per its usage: entertainment and transportation, currently some countries allow the balance scooter to travel on the road under below conditions:

Netherlands:

Cardiopulmonary disease patients can use the balance scooter as a medical auxiliary equipment, other balancing scooters are not allowed to use in public roads.

United Kingdom:

Balanced scooters are motorized scooters, only can be ride in private sector after permission .

Sweden:

Recoginzed as motrised vehicles but can not pass the basic specifications certification of electric vehicle, prohibit on the road.

Germany:

In some areas,hoverboard regarded as the electric wheelchair type of balancing scooter, allowed to travel in the bike lane or sidewalk.

Japan:

If you want to drive the hoverboard on the road, the hoverboard must be equipped with brakes and headlights, brake lights, direction lights and other auxiliary equipment, the owner also need to pay tax ,register a number and have a driving license.
