Xiaomi No.9 and rider Smart-Pi, the defending battle in the field of balance car, which is more powerful?
CHIC and Ninebot are two major balance car brands in China. The former relies on the Computer Aided Product Innovation Design Engineering Center of the Ministry of Education, the School of International Design of Zhejiang University and the Key Laboratory of Service Robots of Zhejiang Province. Many balance car companies at home and abroad are authorized by CHIC, while Ninebot of Nainbo completed its transformation by acquiring investment institutions such as Segway and Xiaomi in the United States.
Nainbo Ninebot is a member of Xiaomi ecological chain. Xiaomi No.9' s balance car is actually Nanbo No.9, replacing CHIC rider's Smart-Pi with Netease's domestic H 1 balance car. These two electric balance cars are the latest models of the two major balance car brands. Let's compare these two balance cars to see which one has better quality and performance.
First, the appearance of the product From the appearance of the product, the rider Smart-Pi is more light and flexible. Although it has the function of walking instead of walking, it is more like a high-end toy in the shape of a teenager's fox pet, while Xiaomi No.9 balance car has a more business sense, looks like a middle-aged business person with a strong fist. In terms of design, compared with Xiaomi 9' s conservative big black hub design, the cracking of Ryder Smart-Pi's eclectic hub is more avant-garde and dynamic.
Compared with Xiaomi No.9' s big "sexy off-the-shoulder", the rider's Smart-Pi semi-circular streamlined fender design is more humanized and should be more antifouling when driving on muddy roads. In terms of automobile tires, the rider Smart-Pi uses solid tires, and Xiaomi No.9 uses pneumatic tires. The former can prevent unsafe puncture during driving, but at the same time, its seismic performance is not as good as that of the big wheel pneumatic tire of Xiaomi No.9 balance car.
Second, the product material In terms of product material, Xiaomi No.9 frame is made of magnesium alloy, while the rider Smart-Pi body is designed with integrated aluminum alloy. So which is better, magnesium alloy or aluminum alloy?
1, tensile strength
The tensile strength of magnesium alloy is not as good as that of aluminum alloy, so the magnesium alloy with the same effect is either large in size or low in strength, so aluminum alloy has more advantages.
2. Fatigue strength
The durability of magnesium alloy is worse than that of aluminum alloy, which is also the fatal disadvantage of magnesium alloy. The more times you ride, the lower the strength will be, and even the service life of the frame will not exceed 2-3 years, so professional riders rarely use magnesium alloy frames.
3, metal oxidation
According to the periodic table of elements, we know that magnesium alloys are more prone to oxidative corrosion than aluminum alloys.
4. Manufacturing cost
Because magnesium alloy is an active metal, it requires high manufacturing equipment and environment, which leads to high manufacturing cost and lower cost performance than aluminum alloy frame.
5. Specific gravity density
Magnesium alloy is lighter than aluminum alloy in the same volume, which is the advantage of magnesium alloy.
To sum up, aluminum alloy material has more advantages than magnesium alloy material, so the material of Ryder Smart-Pi is better.
Third, portability As a travel tool, we often need to put the electric balance car in the trunk of the car when we go out, or carry it by subway bus. Therefore, the portability of the balance car is a problem that we must consider, which requires considering the size and weight of the balance car purchased.
The length, width and height of rider Smart-Pi are 583*203* 179, and Xiaomi No.9 is 548*260*595. The total storage space occupied by Xiaomi 9 may be more than four times that of Ryder Smart-Pi. In addition, the net weight of rider Smart-Pi is only 10kg, while that of Xiaomi No.9 is 12.8kg, which is about 28% heavier than that of rider Smart-Pi.
Therefore, from the perspective of portability, the rider Smart-Pi has obvious advantages.
Fourth, is there a joystick? The biggest difference between Xiaomi No.9 balance car and rider Smart-Pi is that Xiaomi No.9 belongs to a balance car with poles, and the rider Smart series is the world's first balance car without poles. Generally speaking, the balance car with poles we are talking about is usually aimed at walking poles. Smart Elf, E Pioneer and Yuhu series all belong to electric balance cars with poles.
However, the control lever of Xiaomi No.9 balance car is located between the legs, and it is easy to hit the crotch when the road surface is uneven or improperly controlled, resulting in secondary injury to the body after falling. Long-term leg friction is easy to cause soreness and redness. In addition, the dual operation of gravity+leg control lever is easy to cause limited action execution, and the flexibility of "center of gravity control+pressure sensing" is not good compared with the rider Smart-Pi. However, the Smart-Pi with toy attributes also has the problem that the riding scene is too sensitive.
Verb (abbreviation of verb) Configuration parameters In terms of machine parts configuration, both Xiaomi No.9 and Ryder Smart-Pi adopt synchronous brushless motors and 1860 lithium batteries, and the motor power of Ryder and Xiaomi is double 600 watts and double 700 watts respectively. Compared with Xiaomi 9, the electromechanical power of rider Smart-pi is slightly lower, which makes the driving speed of rider Smart-Pi lower than Xiaomi 9 to some extent.
The maximum cruising range of the rider's Smart-Pi is 20Km, that of Xiaomi 9 is 22km, and the rider's Smart-Pi is slightly lower than Xiaomi 9. In terms of driving speed, the rider's Smart-Pi is 10km/h, while Xiaomi No.9 can reach 16km/h, which is obviously higher than the former. In terms of load, rider 100kg, millet 85kg and rider 15kg. In addition, compared with Xiaomi's charging time of 4 hours, the charging time of rider Smart-Pi is 3-4 hours.
Sixth, the riding experience The author experienced these two balance cars respectively. From the product appearance and riding posture, the fashion and coolness of the two balance cars are comparable. The big wheel hub and hollow tires of Xiaomi No.9 balance car make it superior to the rider Smart-Pi in terms of impact resistance and pothole prevention when riding. The rider Smart-Pi is more flexible when riding, but the leg operation of Xiaomi No.9 balance car is inconvenient. ?
In terms of display, rider Smart-Pi has built-in many cool lighting effects, such as running water lights, flashing lights, double flashing lights, starry sky flashing, red and yellow warning lights, and Xiaomi No.9 LED light group is more practical, with front lights and taillights. Relatively speaking, when driving at night, the rider's Smart-Pi display effect is better, the entertainment attribute is stronger, and the lighting effect of Xiaomi No.9 is better.
Seven. To sum up, we can know that Xiaomi 9 is aimed at the travel scene, and the rider Smart-Pi has strengthened the entertainment function on the basis of the travel function. Both have their advantages and disadvantages. The rider's Smart-Pi is superior to Xiaomi No.9 balance car in terms of materials, portability and entertainment display, and Xiaomi No.9 is superior to the rider's Smart-Pi in terms of transportation. You can choose to buy according to your own needs.
