The use of bike sharing in the past two years has indeed made life much more convenient, but in the rush hours, the chances of being able to scan bike sharing near subway entrances and bus stops are still poor. It takes 20 minutes to walk from the subway exit to the company's downstairs. Today, at 8:30 in the morning in Shenzhen, the sun is scorching. When I walked to the company, I was sweating. I spent half an hour of makeup in the morning. As for me, who just came from the society, there is no condition to consider my private car. As a result, a courtesy car like Big Fish Smart Drive is what I have always been thinking about.  

It is said that men decide whether they want to contact a woman by their appearance, and whether they want to stay with her by their quality. Women are also members of the Appearance Association. A good appearance is a necessary prerequisite to guide me to choose this thing.

The Dayu D1 adopts aluminum alloy body and frosted baking paint. The overall body is compact and simple. The size of the car is 1050 * 500 * 960mm, and the overall weight is only 12kg. At a glance, the most obvious is the battery box in the middle of the car. The battery box is like a capital Chinese symbol "," and more like a dolphin jumping into the water. The battery box is placed in the middle of the car body, which greatly saves space. The dolphin shape also makes the whole car more elegant. The inspiration of the designer also comes from the dolphin, which symbolizes the free and free shuttle of the dolphin in the water.  

The battery of Dayu is a 36V 10ah lithium battery of Chaowei, with a range of up to 50km, which can fully meet the daily travel needs. And the battery supports fast charging, which can be fully charged in about 6 hours. There is a handle on the top of the battery box, which is convenient for getting in and out of subway, elevator and other places where it is inconvenient to ride. Because of its light weight, girls can also easily lift it with one hand.  

The design of the front part is very simple and refined. The handlebars are made of rubber, which makes them feel more comfortable. The handle surface has anti slip lines, which is convenient to control. A slack adjuster is arranged in the middle of the head, and the tilt angle of the whole handlebar can be adjusted by loosening it. There is a red horn button on the left handle, and the toggle switch of the power supply.

The right handle is the accelerator, and there is a green cruise button beside it. When driving at a certain speed, press this button to make the intelligent vehicle drive at a constant speed. When you press the key again or press the brake, the cruise function will be cancelled. There is a display screen above the cruise button to display the power. The only regret is that the head cannot be adjusted.  

Below the front of the car is the automatic induction lighting. When the light is dim, the headlights will sense the ambient light and turn on the headlights automatically. Of course, it can also be set to be manually turned on in the app. Manual opening is operated in the app, which is slightly troublesome. A small disadvantage is that the lights can't rotate with the front of the car, and it is inconvenient when turning.  

At the same time, there is also an intelligent brake LED light at the rear of the car. When braking, it will light up highly to warn the rear of coming cars.  

The Dayu D1 is equipped with 12 inch shock absorption tires, which are slightly smaller than ordinary electric bicycle tires. However, Big Fish uses rear wheel drive, which has sufficient power. The shock absorbing tires can perfectly adapt to various gravel roads, steep slopes, speed bumps, etc. During the actual test, I felt very stable without any discomfort of turbulence. The front and rear tires are equipped with highly sensitive dual disc brakes, which have stable and sensitive braking effect and high safety coefficient. In addition, the front and rear wheels are equipped with mudguards, so you don't have to worry about throwing mud on the muddy road!  

The split weight seat fits the buttocks more closely, effectively relieving the discomfort of the buttocks caused by a long ride. Of course, it is recommended that the height of the seat be adjustable, so that more people can use it.  

Big Fish's foot pedal is quite different from other traditional electric vehicles. Big Fish uses a hexagonal aluminum alloy foot pedal in the center to free his feet and make them more relaxed and casual.  

The speed of Dayu D1 can reach 20km/h. After the new car travels 10km, the speed can reach 30km/h. The maximum climbing angle can be 25 degrees.  

As an intelligent travel device, it must be able to do more intelligent management. On the main interface of the Big Fish app, the current battery power, mileage, speed, electric vehicle temperature, etc. of the car can be directly displayed. The three buttons below the main page are "Settings", "Positioning" and "Track". The app also has functions such as electronic fence, riding track, self inspection, etc.  

The Big Fish makes me think of two favorite functions. One is the GPS positioning function, which can check the location of the car anytime and anywhere; The other is the triple anti-theft function. Through the app, the car can be locked with one key, the motor can be locked completely, and there is an electronic fence. When the car exceeds the protection range, it will automatically send a location reminder, and then through GPS positioning, the location and movement track of the car can be accurately located. It is very effective to prevent the car from being stolen.  

Most importantly, the price of such a light, compact and intelligent car, less than 2000 yuan, is quite affordable. It is very practical to shuttle between the flow of people to work and the daily short distance travel, but as a first generation smart car with impressive appearance, it does not make the whole city uncomfortable, such as the non detachable battery, the inability to adjust the seat height, etc., but it is believed that with the product optimization, it will get better and better.
