China is a big bicycle country, and the number of bicycles per capita has reached 370 million by 2013. In the face of such a market prospect, as well as the low technology access threshold and the subversion and innovation of "Internet thinking" on this traditional product compared with electric vehicles, smart bicycles have attracted domestic brand leaders and hardware entrepreneurs.

In fact, when bicycles are deeply branded with "intelligence", we should not think deeply about what is "intelligence". Then the author will use the evaluation experience of Cloud Horse C1 intelligent bicycle of Cloud Manufacturing Technology to discuss whether we need an intelligent bicycle to enter our life?

Whether it meets the standard of a traditional bicycle!

Yunma C1 is positioned as a city bike. According to the founder of Yunzao, the name of Yunma C1 is from city, classic, colors, cloud However, as a smart bike, whether it is an urban e-bike or a bicycle, its essence is still a bicycle. The product cannot discard its essence because of its intelligence. Therefore, the first consideration for Yunma C1 is that it is the standard for traditional bicycles.

Yunma C1 takes a light route as a whole. The pure black tires and dark all aluminum alloy frame, together with the orange battery box at the rear of the car, are steady and energetic on the whole. In terms of face value, it is definitely ranked well among bicycles. Although appearance is important, features other than appearance such as function, performance and safety are more important for a vehicle.

The body structure of Yunma C1 adopts a non-standard "dead flying" shape. The hollow all metal aluminum alloy triangle frame can not only ensure the stability of the body structure but also control the body weight. In addition, the 20 inch small wheel design contributes to the portability of the body, which is conducive to going up and down stairs in urban life.

On the whole, the features of Yunma C1, such as its high appearance, its classic shape and small wheel design, have won many highlights for the product. Next, the author will experience it in modules.

It is also a faucet with the smell of dead flying. It is made of aluminum alloy and looks very impressive. The two handles are covered with silica gel to increase friction and alleviate discomfort caused by sweating.

The bell is a relatively common bell, small in size but crisp and powerful in sound, which basically meets the daily use; The brake handle is also made of metal, which will not be corroded and aged due to long-term use. However, from the actual experience, the braking force is too hard, and it requires a certain grip strength to achieve the braking effect. From the overall strength, it is not a problem for an adult, but if it is dealing with a rough downhill road, it may have a greater sense of fatigue.

A plastic mobile phone bracket was also presented with the car on the handle. It was learned from the packaging that this mobile phone bracket was not customized by Cloud Manufacturing Technology, but a finished product directly bought from the market (the brand could not be disclosed). However, from more than 10 days of cycling, the stability of the mobile phone bracket was poor, Large screen phones like the iPhone Plus series may fall down on slightly bumpy roads.

According to the official website, Yunma C1 uses CNC pole handle. It is believed that many people are not very familiar with the ranking of CNC. In fact, CNC is a computer numerical control machine tool The control system can logically process the program with control code or other symbolic instructions, decode it through the computer, so that the machine tool can perform the specified action, and process the blank into semi-finished finished parts through cutting tools, which is, in human words, cut as a whole. Despite the official beautification, it is unavoidable that the faucet cannot adjust its height. Due to design reasons, C1 cannot adjust the height of the faucet at will.

In fact, for a car leader, the introduction is almost enough, but Yunma does have a bonus item that cannot be ignored, that is, "simple central control". To achieve this effect, it is not possible. In fact, it only needs a cable take-up device, which can be achieved by combining two brake wires and a "wire". It does not seem to be a big deal, However, such micro innovation has improved the aesthetic feeling and practicability of our products.

The front and rear wheels of Yunma C1 adopt the V brake design. In fact, for a lightweight bicycle in a major city, it is reasonable to adopt the V brake. Because the weight of V brake is much lighter than that of disc brake. We will not say whether the V brake and disc brake are good or bad for the moment, because both have advantages. The V brake of C1 adopts an adjustment button that is very easy to adjust the brake sensitivity, which is convenient for users to adjust in time and increases the practicability of a single car.

Speaking of tires, since C1's compact body cannot be equipped with large tires, and men's and women's small wheels are 20 inches in size, the tire model is not clear. The whole tire is characterized by small size. Since the body is not equipped with a shock absorption system, the small tires have a particularly strong vibration on the potholed road, and a long ride will increase fatigue and even pain. Although it is oriented to urban cycling, However, there are still some defects in the basic pothole handling route in C1.

In addition to the battery box of Suohuang, there is a red spoke on the tire spokes to increase the vitality of the bicycle. The wheel hub is made of aluminum alloy. What is unexpected is that C1 uses French valve. The author failed to find the corresponding adapter when he went to pump air for the first time. It is also difficult to buy a cylinder with a French valve adapter in the supermarket, As a product with high pumping frequency, this design undoubtedly greatly reduces the convenience.

Yunma C1 uses leather material on the seat, and has designed corresponding grooves according to the sitting posture of the human body to alleviate riding fatigue. The seat height can be adjusted by loosening the screws at the bottom of the seat. Since the head cannot adjust the height, the overall body has some limitations in adapting to the height of the ride.

In terms of details, C1 is equipped with all metal pedals, which increases the anti-skid design and ensures the safety. At the same time, a brace is added to the rear wheel for parking. If you think that's all? In fact, C1 adopts a modular design at the gear disc. For those users who have certain requirements for riding, they can replace the gear disc by themselves later.

In general, Yunma C1 is well behaved in terms of bicycles, meeting the requirements of a traditional bicycle, but on the mudguard. There is still room for improvement on some problems such as the shock absorption system.

How effective is it?

In addition to being a traditional bicycle, the main function of Yunma C1 is electric bicycle. As an electric bicycle, we have to mention energy, power and control system.

The energy system is mainly the battery box of Suohuang behind the bench. C1 uses Samsung's 5.1AH 18650mAH lithium battery. The official endurance in the pure power assisted mode is more than 25 kilometers. From the experience, it is still competent on a gentle road of 20 kilometers.

Cloud Manufacturing Technology uses different colors to decorate the car body by hanging the battery under the back of the seat, and incorporates the taillight behind the battery box. The taillight has four different modes. It is precisely because the rear of the battery is suspended behind the seat that this design brings a lot of inconvenience to the installation of the rear seat.

The battery box can be unlocked and unloaded by the key. The 42V 2.0A specification is used for charging. It takes 3 hours to fully charge the battery box. In fact, there is also a USB interface hidden on the back of the battery. The output standard is 5V 1.0A, which can charge mobile devices.

YunMa adopts its own self-developed YunBike motor. The whole motor is designed at the rear wheel of the bicycle. Officially, it is described as being able to achieve 5-gear power assisted regulation. The author believes that it is more appropriate to divide it into three gears: traditional bicycles (no power assisted), power assisted vehicles (25% power assisted, 50% power assisted, 75% power assisted), and electric vehicles (100% power assisted).

It can be seen from the note on the motor that the specification of Yunma C1 motor is 36V 180W. According to the official introduction, the bicycle is equipped with a 3-axis acceleration sensor and an axis gyroscope, which can automatically increase power assistance when climbing. The author found that this function is very convenient to use in actual experience. It is a pity that the motor is not equipped with a power recovery system.

Like all electric vehicles, the entire central control system of a single vehicle is concentrated on the tap. The tap part is integrated with a code meter display, a power assisted adjustment button and a pure power assisted switch. The display of the code meter integrates information such as the speed of a single vehicle, total mileage, and power. The whole code meter is waterproof and suitable for rainy days. On the right side of the display are two adjustment buttons, which are used to adjust the boost mode (25%, 50%, 75%).

There is a pure power assist switch on the lower right side of the stopwatch. It is officially announced that the next time you press the switch when the speed is greater than 4.2km/h, the pure power assist mode can be started. However, after the actual measurement, it is found that the pure power assist mode needs to meet two conditions: the speed is greater than 4.2km/h and the pedal turns. In short, even if your speed is faster, the pure power assist mode cannot be started when you do not step on the pedal, The pure power assisted mode can only be started when the pure power assisted switch and pedal rotation are met at the same time. On the gentle road, because the pure power switch cannot be locked and must be pressed for a long time, the long journey is very tiring, and this starting mode is too expensive for beginners to learn.

During the actual measurement, the maximum speed can reach 26.4km/h under the no-load state of pure power assistance.

Under the code meter, there is also a USB interface hidden in the body, which is also the 5V 1.0A output standard, and its function is also to charge mobile devices.

In terms of safety, C1 adopts its own power-off brake technology. No matter what power assist mode, the motor will be powered off in an emergency when the brake is pressed. In my opinion, this is the most intelligent embodiment of the whole bike, which can really solve problems.

As an electric bicycle, Yunma C1 is also equipped with a lighting system. As long as it is turned on, the daily running light of the bicycle will light up, and the off switch will not be provided for the time being. The headlights of Yunma C1 are composed of four LED lights and a circle of daytime running lights.

In the night state, four headlamps are turned on, which have a wide range of illumination and large brightness, fully meeting the use of night riding. The whole lamp system also adopts the waterproof design.

Smart APP that takes the hindmost step

Every "team" has a pig teammate. If the bicycle product is good, the "Smart Train" APP is the pig teammate. In the smart train, cloud technology integrates the official community, where users can see, post, write reviews, and even see the location of nearby C1 riders, not to mention whether there are users actually posting on the mobile end Write a review. I can see what the nearby car riders can do? Therefore, many functions of the intelligent driving APP are merged.

The author also found two points worth learning from other manufacturers in the APP. As an intelligent product, security accounts for a large proportion. Cloud Manufacturing Technology launched a "lending" system in the APP. Other users do not need to scan the two-dimensional code on the car body, but can complete the binding through the digital password of the key shared by the car owner, but the ownership belongs to the car owner.

Another point is the single car health detection function, which can simply detect the health status of Yunma C1 in the intelligent driving APP, and increase the safety before travel.

As an APP for intelligent bicycles, what I hope to see is the navigation system and anti-theft system, rather than the functions of the PC end directly transferred to the APP.

Purchase suggestions

For a bicycle, its function is nothing more than exercise and walking. As an electric bicycle, the exercise function has been removed in the sense of gross weight, and the only use is walking.

From the perspective of transportation, Yunma C1 has reached its standard as an "Internet bike", but the purpose of intelligence is to make people's lives more convenient, rather than more complex and more expensive. It seems that cloud manufacturing technology does not charge exorbitant prices like LeEco and other manufacturers, which meets the standard as an intelligent bike.

Therefore, if you are an urban person and need a bicycle as a short distance transportation tool, Yunma C1 is still a good choice. The price of 1999 can also be accepted by many consumers. However, if you want to exercise or take long-distance transportation, mountain transportation and other needs, Yunma C1 is difficult to meet.
