Introduction

Harley Motorcycle has a history of one hundred years in the world since 1903. Over the past hundred years, this brand product has brought people not only a wild appearance and superb performance, but also a symbol of the spirit of freedom. With the continuous innovation of modern urban life technology, this kind of motorcycle in the traditional sense has gradually separated from the modern urban transportation system, and has been replaced by various electric vehicles. Whether it is a highly intelligent electric vehicle, a small and portable unicycle balance car, an intelligent electric scooter, etc., these new transportation tools not only have the characteristics of portability, lightness, intelligent control, etc., but most importantly, their electric endurance has made great contributions to environmental protection. However, only in these products can the spirit of freedom like Harley motorcycle be found, which is Ghost One, a Gauss De to Jane electric intelligent scooter. Next, let's have a close look at the cool experience of this locomotive with Xiao Bian.

Appearance display

On October 12, 2015, the Gaosid intelligent electric scooter quietly landed in JD crowdfunding, and in just 12 hours, it broke the target of 100000 yuan, which shows how much people like it. Fashionable and simple appearance, safe and comfortable driving experience, all show the spirit of freedom and unrestrained.

At the first sight of Ghost One, it is easy to think of Harley motorcycle, with its high handlebars, rough and wide tires and large-area pedals. Ghost One brings users an unprecedented retro experience with the design concept of keeping improving. It can also be said that this is a new product that integrates electric vehicles and scooters. It not only has a domineering appearance, but also has a stronger sense of balance brought by the ultra-low center of gravity and large tires to ensure users' riding safety.

The product concept of Ghost One intelligent electric scooter is "simple in shape, intelligent in mind". The whole locomotive body is indeed simplified in shape, even the battery can not be seen on the surface; There is also no rearview mirror, horn, keyhole and other designs on the handlebars. Apart from the brake device, the most prominent one is the integrated aluminum frame. In fact, the Gauss electric scooter has a lot of similarities with the German "Scrooser". Both of them use the simplest and most fashionable shape to bring users a cooler and more comfortable experience. In order to better understand Gauss Smart Electric Scooter, I summarize the relevant parameters as follows.

Detail display

The rear of the seat is marked with the trademark "GHOSTone", which is the only place where the whole locomotive has a LOGO. Gausder Technology Co., Ltd. is a domestic intelligent electric scooter, which is based on the product concept of "simplicity and intelligence" and is responsible for users. Although the company was founded late and the product itself is still in its infancy, I believe that Gosdel will improve this cool electric scooter better and better.

Whether it is any electric vehicle, the braking system with good performance is the key to ensure safe travel. Ghost one intelligent electric scooter adopts Yanhao Tektro professional power off brake system, which uses the mechanical disc brake principle to clamp the brake disc through the brake line control to produce braking effect. Because the scooter obtained by Xiao Bian is a standard version (the performance version uses hydraulic disc brakes), the mechanical disc brakes have a general experience effect. The car has a long braking distance in the process of fast travel, and it is hard to tighten the brakes. You can see the actual brake performance in the video display.

In order to make the packaging more convenient, the handlebar and the body bracket are separated when the car arrives, and they need to be installed and fixed with an L-shaped hexagon wrench. Because the control direction of the whole handlebar is realized through this small connection module, it is necessary to tighten two screws during the installation process to avoid any looseness, otherwise there will be potential safety hazards.

There is a cross shaped LED light in front of the frame. Because this Gauss electric scooter is still in the stage of crowdfunding and testing, the model obtained by Xiao Bian has no actual installed light source. However, the shape of the lampshade is still beautiful. I hope that high brightness lights can be installed later to facilitate users to ride at night.

The angle between the handlebar and the frame can be adjusted, so that users with different arm lengths can have a comfortable feeling of control. In addition to the brake line of the bright line, the front of the electric scooter is very simple, again highlighting the theme of simplicity. Some friends may ask why there are no rear view mirrors, speakers and other accessories? I think that this is the highlight of Ghost one itself, which simplifies the complexity.

There is a power control switch at the front end of the pedal, which is used to control the front and rear light sources of the electric scooter and the locomotive battery to power on, but it does not mean that like the electric car key, you can start the scooter by touching the switch; It also requires a smart Bluetooth key to realize the start and stop control of the vehicle, which will be explained in the disassembly section later. I think this switch should be disconnected from the simultaneous control function of front and rear lights and power supply. After all, there is no need to turn on the lights when riding in the daytime, which causes a certain waste of power.

The six LED tail lights on the rear mudguard remain on constantly during riding, and will flash continuously and rapidly when braking, which will prompt the pedestrians and vehicles behind, and the effect is more obvious at night, bringing sufficient guarantee for driving safety. The drawback is the integrated design of the lights and mudguards. If the mudguards are damaged for a long time, they need to be replaced together with the lights, which is expensive.

Ghost one The car seat is relatively wide, and the two aluminum alloy tubes used to support the bottom appear very stable; The seat is made by the double tangent sewing process. The uniform and neat surface of the sewing thread is clearly visible. The material is relatively soft. It's very comfortable to sit on it. From these details, we can see that the rough and bold appearance of the Gaosid intelligent electric scooter is also full of such delicacies, and sincerely praise it.

Such a fashionable electric scooter always attracts many curious and envious eyes when riding on the street; People usually ask a small question, where is the battery of the electric vehicle? In fact, it is hidden under the pedal. The pedal area is enough to place the feet, which is also the main embodiment of the product's integration of scooter style; The bottom of the pedal is only 100mm from the ground, and such a low chassis height makes standing riding a reality. The pedal is processed with bright surface baking paint process, and the tread pattern will be worn for a long time, which will affect the appearance. It is recommended to replace it with model material, and I believe the effect will be better.

The fenders of the front and rear tires are very bright through the UV UV curing painting process, but the practical performance is not very good. Careful friends can find that the rear fender has been hit and cracked during express transportation. Similarly, the fixing method is just a simple two-point connection of the frame, which is too close to the distance between the tires. When riding on bumpy roads, it often rubs with the running tires. It is recommended to replace the mudguard with more solid material, and improve its fixation mode without affecting the aesthetic degree to extend its service life.

The front end of the frame is the charging connector, the GPS positioning module and the connector positions of the front and rear light sources; This kind of hidden design is very good, but the GPS module is a bit rough when it is pasted only with glue, and it will fall off after several cycles; Also as a function of anti loss positioning, it is safer to place it in the locomotive pedal.

Ghost one The frame is surrounded by several short and continuous arc frame systems, and is made of high-strength 6061 aluminum alloy tubes, which can provide users with strong riding stability and support performance. Rather than saying that Gauss De's product is to remove as many structural parts of traditional electric vehicles as possible, presenting a subtractive beauty; Rather, it leaves room for DIY for users themselves. There is enough space on both the front handlebars and the rear frame to install various multifunctional accessories such as lights, sports cameras, bells, mobile phone holders, etc.

The front and rear axles of the locomotive are 222mm above the ground, and three fifths of the overall weight is below this height, bringing a lower center of gravity to the vehicle. It has good handling performance during driving, and can keep upright in static state with wide tires. However, the lack of consideration is that if the road surface has a certain gradient, the locomotive cannot be placed statically. It is recommended to add a hidden ladder, which can be used when parking on the slope.  

Detailed explanation of tires

Ghost one One of the highlights of the intelligent electric scooter is undoubtedly its cool and aggressive tires, which is also an important reason for Xiaobian to show it separately. So what is the original design intention and actual experience effect of this large tire? The tire specification given on the official website is 18 * 9.5-8, but the actual measurement shows that the maximum outer diameter contour of the tire is close to 20cm. This kind of multi terrain straight pattern tire can bring excellent trafficability to the vehicle by taking advantage of its wide and thick dimensions.

The official said that the flexibility of the tire can bring shock absorption effect to the vehicle, but Xiao Bian found that the shock absorption effect is ordinary after several days of riding tests; It feels very bumpy when driving on uneven roads. It is recommended to add a shock absorption system to give users a more comfortable riding experience. The installation and removal of tires are very convenient. Only the part connected with the support needs to be separated, which makes maintenance easier.

I personally think that the original intention of Gauss Electric Scooter to use wide tires has two points. One is the drafty effect of the locomotive appearance. After all, such a new locomotive can attract many people's attention when it runs on the street; The other is the stability. The wide tires and the ultra-low center of gravity are enough to ensure the safety of the vehicle when riding, without tipping. The corresponding disadvantage is the handlebar steering maneuverability. The handlebar part can rotate 360 degrees, but it is difficult to achieve turning at high speed; We need to use the side tilt of our body to move the position of the center of gravity, so it is easy to control a lot.

Ghost one The comparison of tires with Audi cars and vans shows that the width of Gauss Smart electric scooter tires is wider than the other two; The thickness is also roughly the same as that of Audi, which is why this locomotive is so stylish.

Cycling test

Because of its wide tires and heavy body weight, the Gaoside intelligent electric scooter is not very suitable for girls to ride, and it seems to be powerless in direction control; However, the cutest girl will instantly become a domineering woman when she rides this scooter.

Only when you sit on a car with a fat paper like Xiao Bian, you can feel comfortable. The width of the pedal, the height of the handlebar and the length of the seat are all very suitable.

In addition to the ordinary electric vehicle function, Ghost one can also slide like a scooter, and users can directly stand on it and ride; Because the ultra-low center of gravity does not need to worry about the possibility of toppling, which adds more fun to its play.

The steps beside the road are generally 10-20cm high, and the electric scooter can easily cross without scratching the floor. The power provided by the rear wheel motor is also very strong. You can go up to the steps by slightly twisting the accelerator.

Now let's test the braking distance of the electric scooter. Raise the speed of the scooter to the maximum on the lawn of the playground. When the front wheel drives to the white line, start to brake with a single car. After two tests, the braking distance of the front and rear disc brakes is about 3.2 meters when they are applied separately.

When the front and rear brake systems are used at the same time, the braking distance is about 2.2 meters; It is also recommended that you use the front and rear disc brake system at the same time during daily riding, which can not only brake the scooter more quickly, but also reduce the serious wear of a single disc.

Ride around the 400m rubber track and use the mobile phone stopwatch to count the time. The time of the cycle is 54.9 seconds. Through calculation, the average speed of electric scooter is 26.23km/h; Because the test place of the small editor is on the school playground, there are many runners and morning exercisers who should pay attention to safety while riding, and do not use the maximum speed throughout the whole journey. Therefore, the speed of the scooter is close to the official 30km/h.

Such a cool locomotive always attracts many curious questions from passers-by. The elderly on the whole playground also ask questions about the car, such as the location, speed, price, manufacturer, etc. of the battery. Of course, Xiaobian has been patiently answering questions. Many people want to buy a car from their own homes to use for daily travel.

Disassembly and reconstruction

The naps with strong hands-on ability always need to disassemble and study any high-tech products. This Ghost one intelligent electric scooter is no exception. Through disassembly, we can help you better understand the working principle and performance characteristics of this locomotive. First, use a screwdriver to unscrew 13 screws on the foot pedal, and a layer of aluminum plate can be seen covering it. This layer of aluminum plate can protect the lithium battery below in rainy days to prevent water from entering.

Dismantle the aluminum plate to see the lithium battery of the electric scooter. The 41mm battery thickness makes the battery compartment and frame perfectly integrated in the limited space of the locomotive. The output parameter of the battery is 48V, and the charging time is about 5 hours, which can provide 40-50km endurance power.

The multi piece brushless hub motor independently developed and designed by Gauss De can be easily disassembled with a wrench, which can easily meet the daily maintenance needs of tires and motors. The drawback is that the gap between the mudguard and the tire is too small, and the installation is not very convenient. The mudguard can only be replaced after the tire is removed. On bumpy roads, the mudguard often rubs against the tire, which needs to be improved by the manufacturer.

The tire display after removal, including the wheel hub and tire surface, is very good in workmanship and material, and it is also easy to install.

There is a system and circuit control box in front of the pedal. The accessory of the red square in the figure is the scooter Bluetooth key mentioned by Xiao Bian. This key matches with the internal Bluetooth module of the control box one-on-one. Only when the key switch is activated, the scooter can be powered on for cycling.

Xiaobian found the power connector reserved for the front LED light of the frame in the wiring slot, and measured the voltage with a multimeter to 46.7V. In this way, you can buy some light source devices on the Internet and design your own DIY.

After removing the rear fender, the small braider found that the LED and other plate wiring welding points behind were not firm, and then used an electric soldering iron and a hot-melt gun to weld and fix them again to prevent the power cord connector from falling off during the riding process.

LED The actual effect after the light bar is re reinforced.

Because there is friction between the mudguard and the tire, Xiao Bian solved this problem through his own modification. Pull out the mudguard stuck behind the pedal and fix it on the pedal with hot melt adhesive to increase the gap between it and the tire.

A hard metal protective plate is installed at the bottom of the pedal, which can prevent the wear of the frame caused by the locomotive dragging the ground and play a protective role.

The standard power adapter makes a lot of noise when charging. I hope it can be improved. At the same time, it is suggested to add the function of indicating the amount of charging power. It is not convenient for users to use a full power indicator alone.

Outdoor travel

Find a sunny afternoon, ride Ghost one intelligent electric scooter, shuttle through the streets of the city, and enjoy the joy of the motorcycle.

Although the electric scooter weighs a lot, it is easy to push it. Even when the power is used up, it can be pushed home like a skateboard.

The actual riding record of the small edition shows that the whole journey is 12km, and the maximum speed is 28km/h; Of course, we took photos and walked around for a long time, so we can ignore the time part.

Riding a motorcycle to the food market, even the owner of the grocery store asked about the performance characteristics of this motorcycle curiously.

summary

Because the locomotive APP is still in the development and testing stage, there is no way to successfully register the account here. After consulting the manufacturer, we learned that the server will be opened later for users to download.

As for this evaluation post of Gauss Smart Electric Scooter, the editor has brought so many things to you. There may be some things in the article that are not detailed or comprehensive. Please comment and correct more. In general, this locomotive is popular among users because of its cool and stylish appearance design and powerful and practical functional features; As a new type of transportation, I believe there will be a good sales market space. However, during the evaluation process, Xiaobian also found several shortcomings of the product, which are summarized as follows. I hope the manufacturer can consider the suggestions of Xiaobian.

1、 The electric scooter lacks the indication sign of battery power, and the user is completely ignorant of the locomotive power, causing great inconvenience to travel; It is suggested to add a digital LED indicator screen on the handlebar to indicate the power condition at any time.

2、 The rear mudguard of the electric scooter needs to be thoroughly improved. One is that the material is too fragile; The other point is that the installation mode is recommended to become more simple and convenient, and can realize the adjustment of height and position.

3、 It is recommended to separate the rear LED light strip from the mudguard. Once the mudguard is damaged, it needs to be replaced together with the light strip, which is troublesome and costly; It is recommended to install it in the vehicle seat.

4、 When the locomotive runs on uneven roads, it has a strong sense of turbulence. It is not allowed to rely on tires for shock absorption alone. It is recommended to add an independent shock absorption system.

5、 Although the whole locomotive can remain stationary and upright on the flat road surface, it cannot stop on the slope road surface; It is suggested to add a hidden elevator function to solve the above problems.

6、 It is recommended that the switches of front and rear lights can be turned off separately in the daytime, without affecting the power on state of the electric vehicle, so as to reduce power consumption.

7、 It is hoped that the functions of mobile APP can be developed and improved as soon as possible for users to use.

8、 This set of products lacks a detailed instruction manual. Xiao Bian used it according to his own guess, and encountered many problems in the whole process.

9. The electric scooter lacks a locking anti-theft device. Although it has a GPS positioning module, it cannot lock the scooter; It is recommended to add a locking mechanism so that the user can lock the vehicle by himself to prevent the loss of the vehicle.
