Stepless speed change, convenient travel —— Yunma C1 Trial Experience Report

In 2015, the concept of "green travel, health and environmental protection" became popular, so it was also a year of smart bicycle explosion, followed by the emergence of many smart bicycle manufacturers in China, such as Cloud Manufacturing Technology, LeTV, Begin One, BiCi, Cookee, 700Bike, LIVALL and so on. In addition to the different types and materials of traditional bicycles, each brand has its own unique secret. In terms of GPS positioning, speed code meter, intelligent anti-theft, intelligent assistance and other functions, each product has its own unique functions and concepts different from those of other brands. This time, the author brings you the experience sharing of Cloud Horse C1 intelligent driving of Cloud Manufacturing Technology, thanks to the trial opportunity provided by Lei Feng.com, and thanks to the successful exchange brought by the magic right hand.

We have been waiting for the arrival of Yunma C1, and we are also wondering whether we need to call foreign aid for the installation of a pile of bicycle parts. After receiving Yunma C1, unpack it and find it, OK! I can do it alone. Use the complimentary tools to install and adjust the handlebars, pedals and seats, and assemble them easily in full accordance with the instructions.

During the assembly, a head mounted camera was used for recording, and it took 30 minutes to complete the installation under the interference of the baby at home from time to time. If you are interested, you can go and have a look (I feel dizzy when I look at it myself, and the head mounted camera shakes too much). //v.qq.com/page/i/x/q/i0180lkusxq.html

Yunma C1 is positioned as "the most knowledgeable motorcycle for young people", suitable for urban cycling. Therefore, the fashionable small wheel car is selected as the model, and the overall structure is very compact. Its own weight is 16kg, which is very light compared with ordinary electric bicycles. According to the official introduction, YunBike C1 uses YunBike autonomous motor (integrated with rear wheel), with a rated load of 120kg (always worried about small tires).

Yunma C1 adopts a modular design, which is broken down according to the work. It is the simplest unpowered state to drive Yunma C1 by pedaling. When choosing electric, step on C1, the battery will provide power, and the YunBike motor will start to help you reduce your workload. The battery also provides lights in front of and behind the car. So let's look at the details of Yunma C1 in order.

Powertrain:

Stepless power transmission device Talking is stepping. Distinguish between left and right and reverse tooth installation. Only use the free wrench to complete the installation. Anti slip teeth and reflective strips are available.

Next is the hybrid system. The YunBike autonomous motor used in Yunma C1 gives you a powerful boost when there is power, and will not cause resistance when there is no power. The complaint is whether this cargo causes C1 to be unable to use the disc brake, and the maximum speed can only be 25km/h.

According to the power transmission, the next is the driving gear. C1 adopts a transmission gear ratio of 46T: 16T. Without power assistance, this gear ratio will make you feel muscle tightness and thigh numbness when climbing. The chain is too bright, hesitating to add lubricating oil. There is no sound when turning, and the reverse sound is crisp. One word, cool!

Yunma C1 uses a high-capacity battery. When the battery is full, it can complete 22 charges of IPONE or 5 charges of IPAD, which is very convenient.

The only key of the whole car is used here. Use the key to exit the thimble to pull out the battery. If you lose your keys, you can only ride as a dynamic bicycle.

Braking system:

Wisdom in action is more about stopping, and safety is more than everything. Although Yunma C1 uses the traditional C brake, its safety is up to scratch. When you brake, the power system will automatically disconnect the power.

Yunma C1 rear brake still feels that the C-brake is not safe enough in the actual use process, and the braking distance will also be correspondingly extended in the long downhill. In an emergency, the C-brake is a little weak. Therefore, it is strongly recommended to consider disc brakes with higher safety performance.

Control system:

This is the control center of Yunma C1. Choosing a different mode can determine your assistance mode. It can not only check the current speed, driving distance and endurance. It can also control the level of power assistance when riding. Five power take-off modes can be selected according to different road conditions.

Yunma C1 power assistance can be selected from no power assistance to 100% power assistance by right hand switching. The switch of 30%, 50% and 70% is controlled by the+- button on the instrument panel. For the 100% pure electric mode, just keep your foot on when the speed is more than 5km/h, and use the dial on the right side of the instrument for pure electric cycling. At this time, your foot can not move. After releasing the dial or the brake is powered off, enter the power assisted mode.

There is also a USB charging port under the control system, so the phone is not afraid of losing power. After the function introduction, let's take a look at the details of Yunma C1.

The rubber handle is very soft and not afraid of slipping.

The included mobile phone clip is very convenient to use.

The cushion, height, front and rear can be adjusted.

The mounting hole of the mudguard and the installation position of the water cup are reserved, so that Yunma C1 can be fully armed later. Let you ride more conveniently.

In fact, many people say that the battery interface is difficult to install, but they think it is good. After all, it is soft and can be slightly bent.

Software APP:

The APP interface of Yunma intelligent driving mobile phone is very simple and easy to operate.

The gathering place of C1 users in the community can share the things and problems encountered during cycling. The intelligent driving segment is a popular recommendation and after-sales area, with special personnel to solve problems. You can invite Yunma users nearby to ride together. The whole APP classification is still very clear. You only need to be familiar with it.

The headlights can be turned on through the mobile phone APP. Unfortunately, they still need to be turned on manually now, waiting for the improvement of Cloud Maker.

The unique motor physical examination includes three items, and self check your car from time to time.

Cycling experience:

During the riding experience, different riding modes were selected.

In the no power mode: without power assistance, it is equivalent to an ordinary bicycle. The speed ratio of the big toothed belt and the small teeth makes it difficult to ride uphill. Because it is impossible to change the speed, I still feel tired going uphill.

30%, 50%, 70% power assisted mode: in the power assisted mode, when the speed exceeds 5km/h, you can obviously feel the power assisted, and when the power assisted speed reaches 70%, you can obviously feel the automatic advance, so you don't need to exert too much force to move forward easily, and keep the speed at 20km/h.

100% power assistance: needless to say, it can maintain a speed of 20km/h throughout the whole journey, saving effort.

Of course, there are still some problems when riding. The fixed speed ratio makes it difficult to ride uphill without assistance; The limited speed of electric vehicles is not suitable for long-distance cycling, but the positioning of Yunma C1 is urban cycling; The small tire improves the fashion sense and reduces the weight, but the shock absorption effect is slightly poor, especially if I need to pass the railway crossing to work, so I can't afford to be injured; Whether the mudguard and chain guard can become the standard configuration, after all, I dare not say that every day is sunny.

Summary and evaluation:

First of all, the fashion of Yunma attracts me from its appearance, and then it is more convenient and convenient. It easily shuttles between cities, leaving behind motorcycles and bicycles. Riding a windy Yunma attracts many eyeballs. Especially dazzling headlights and tail lights not only provide safety. There are also some minor problems in use. Here are some suggestions:

① The user manual is not detailed enough. In fact, all I need is a description of the control mode and the lights. Don't let me fool myself into saying how the headlights can't be turned off and how to get 100% power.

② Please make the mudguard and chain guard into standard configuration. As soon as the speed goes up, the road that the sprinkler passes will be covered with mud. It is heartbreaking, and there is mud behind the battery.

③ A variable speed version will make my normal riding more convenient, and the brakes will be more efficient and safe.
