preface

This is the solution that many balance cars and somatosensory cars want to solve for users, but on this basis, users certainly hope that the product can bring a more pleasant riding experience and a happier way of playing. The four wheel body feeling car is a new generation product derived from the two wheel and one wheel balance car. Compared with two wheels and one wheel, the biggest advantage of four wheel body feeling car lies in two points: first, volume&weight, and second, balance and stability.

Friends who love cool games should have heard of WalkCar from Cocoa Motors in Japan. In China, it is similar to our product in this evaluation - Xiaoi portable car from Flywheel Weir. Of course, there is another product in China called small pocket parallel car, but that product has major defects in the design of turning, while Flywheel Weir has a long experience in electric vehicles, so there is a big gap in experience between the two products. To be fair, we will not put the two products together in this evaluation.

For Xiaoi, the most concerned issues before the experience:

1. Whether it is portable, and whether the volume and weight are satisfactory.

2. What is the balance controllability and comfort of riding.

With these two questions, let's take a video to see what kind of experience this Weir mini i will bring us.

Simple unpacking

One word unpacking, of course, first of all, thanks Love to play computer games This evaluation opportunity provided by the crowd test. From the official nominal value, the weight of Xiaoi is not high, and 5.5 kg is much lighter than single wheel and double wheel balance vehicles. The weight is almost the same as that of three ordinary notebooks. The maximum load is 120kg, which is enough for a fat man to play. The endurance is within 15km, which can meet the distance requirements of many times from home to the subway.

The accessories are as shown in the figure. The list is very clear. However, one thing you should pay attention to, from the logo logo of Icarbot shown above, which side do you think is in front of Icarbot and which side is behind him? During my nearly two weeks of experience, many friends around me have also experienced it, but to my surprise, these people were all wrong for the first time.

Yes, this is the first question that the author first communicated with engineers in the product evaluation group: Direction problem! The logo of Xiaoi can easily make Xiaobai users feel that the direction is wrong. In fact, the correct direction of Xiaoi should be to look at the black arrow. Unfortunately, the black arrow itself is integrated into the black pedal, so it is difficult for novices to notice this. Once you stand in the wrong direction, it is very dangerous and easy to fall down.

Product details

The two front wheels of Xiaoi are driving wheels, but the material is hard rubber wheels, so it is easy to "shock the feet" when riding on asphalt roads for a long time. If it is marble, the experience is good. The rear wheels are universal wheels, which are very flexible. Of course, you don't have to worry about whether the rear wheels will change direction randomly every minute? There is no need to worry, because only when the left and right speeds of the front wheels are inconsistent, they will turn. The rear wheels are only auxiliary, not the main reason for turning. The turning design of Xiaoi is very reasonable. If the center of gravity is left, it turns left, and vice versa. Of course, some users who have crowdfunded and used the product may think that the left and right turns are too sensitive. We will explain this in detail in the calibration link of the mobile phone app function later.

A small pocket is attached to the product, which I think is very humanistic, and this is a detail that many manufacturers have not paid attention to. Because the somatosensory car finally needs to step back and forth to ride, there must be shoe prints, dust, etc. on it every time after stepping on it, and it will be very dirty if it is directly put in your backpack (except for those who have a cleaning habit and always wipe it with a wet towel). Therefore, before putting it in your backpack, put Xiaoi in this clean bag, so as not to pollute your backpack.

As mentioned earlier, the weight of Xiaoi is only 5.5 kg, and there is no pressure when it is held by one hand. In addition, Xiaoi has a concave part on the power supply side, which allows us to clasp our four fingers at this part and lift it easily.

The battery installation is also relatively simple, but there is a small problem here. Two metal contacts are used for the connection between the battery and the host, but the contact and the slot can only be inserted with greater force. When the author first used and installed the battery, he was afraid that the contact would be damaged by the force, so he failed to install it correctly after three or four attempts. After asking the engineer of Flywheel Weir, we firmly inserted the power after confirming that there was no problem with it. We hope that the design of power supply installation will be easier in the future.

Before inserting the battery, first unscrew the small knob on the power supply. After inserting the battery, screw the small knob in from the housing to ensure that the battery is firmly stuck in the battery compartment and will not be connected falsely due to the vibration of riding.

Before use, ensure sufficient power. When charging, there is no light display on the small i, but it is displayed as a red light on the charger. After charging, the charger display light turns green. If it can be displayed on the small i indicator light, it would be better.

There is a power switch on the left side of the fuselage, which can be turned on by pressing it lightly once. When it is turned off, it needs to press it for 3 seconds to hear a drip before the power is cut off.

There are two red lights at the rear of the car, similar to the tail lights of cars, to ensure that people behind can clearly see us and prevent collisions at night.

Cycling experience

The driving force of Flywheel Weir is good. It can also move up and down freely on ordinary small ramps in the city. The scenes used by Xiaoi are usually home to the subway or riding in the park, so the maximum speed of 12km/h has met the normal demand.

The author is also a player of Xiaomi balance car and No. 9 unicycle, but compared with Xiaoi's body feeling car, the author likes Xiaoi most because of its safety design, which is also the advantage of the four-wheel body feeling car. Players who have played with the balance car know that when we step on the balance car, the balance car will start front and rear drive, So you need to adjust the front and rear balance immediately after stepping on the balance car; Xiaoi benefits from the stability of the four wheels. When you step on it, you don't need to adjust your balance immediately, but when you stand on your feet and hear the sound of "drip", Xiaoi will start the front and rear drive. In this way, the safety of cyclists can be greatly increased, and junior users can also ride more safely.

Xiaoi can not only ride directly, but also support client related settings, such as scanning the QR code download client in the manual or searching for icarbot.

The Bluetooth connection between the client and Xiaoi is very fast. The first connection may prompt you to upgrade the product. Everyone should follow the instructions on the App, press and hold the power button until an orange progress bar appears, and then release it. Otherwise, the upgrade will fail.

In the main interface of the app, we can see the current running speed, this driving distance, total mileage, current load, startup time, etc., but the measurement in the "current load" column is not very accurate. There are speed limits, atmosphere lights, equipment information, etc. in the system settings, which can be seen at a glance.

Here we mainly talk about "attitude sensor calibration". For some feverish users, they often like to look here and there, move here and try there. As a result, Xiaoi turns quickly and can't ride straight. As a result, they don't know how to deal with it.

Please note that once your small I has difficulty in straight travel (in fact, the steering is too sensitive), you can use the attitude sensor calibration to reset it. Here we must see the following paragraph clearly!!!

For beginners, it is recommended that you call a fat person with heavy weight to calibrate left and right when calibrating left and right, and you can calibrate yourself when calibrating front and back. After such calibration, when you ride, the left and right steering sensitivity is low, which can ensure that the left and right do not sway. Of course, if you want to turn, you need to shift the center of gravity more from left to right.

This calibration method is definitely the best method for novice cyclists to calibrate. I suggest you try it.

In the atmosphere light setting, in addition to the colorful light colors, there are four gorgeous color change modes, which can be changed at will to switch to the cool light mode you want.

Creative play

In Xiaoi's mobile app client, there is a function of mobile phone remote walking, which is like the picture above. This is a function that can't be matched by two wheeled and one wheeled balance cars. Most of the two wheeled and single wheeled vehicles do not have mobile phone remote control settings. Some brands, such as Xiaomi two wheeled balance car, can also use remote control, but it will tilt before and after walking. In addition, the platform area is small and can not load. The Flywheel Weir I can take a baby in his body feeling car. Even though Xiaobao is 4 years old, Xiaoi is very powerful. After a word of disagreement, he ran with the baby~~~, and the Iron Man behind him was dumbfounded. jpg~~~

Of course, for adults, we have more ways to play, such as For example For example, picking up garbage Awkward (if this is also a creative play). It is a fun little game to race with friends to cross obstacles and pick up garbage.

summary

Although Flywheel Weir's product design of portable body feeling car is not the first in the world, Flywheel Weir is the pioneer of four-wheel portable body feeling car in China. The biggest advantage of Xiaoi is that its volume and weight are much better than those of two wheeled and single wheeled balanced vehicles; The other is the natural and unique safety of the four wheels. When we stand on the pedal, we do not need to adjust the front and rear balance in a hurry like other balance cars, but drive forward and backward after hearing the sound of "I drip", which greatly increases the safety of beginners during practice. The function of remote control with mobile app client is full of power, and the speed per hour can also meet our normal needs.

The only unpleasant point in the overall experience is the driving wheel of small I. After all, the wheel diameter is too small to use pneumatic tires, so when there is a slightly uneven asphalt road surface, you will feel your feet numb. This is also a point that Xiaoi should pay attention to in the subsequent product upgrades. I hope Xiaoi can do better in terms of comfort.

The above is all the evaluation contents of Flywheel Weir's small cloud car portable sense car. Thank you for watching, and thanks again for the trial of Lei Feng.com. Love computer, start from bit by bit!
