This product of 700bike Backstreet should be the second time to meet. The first time was at an e-commerce exhibition. A brief experience of red car was not satisfied. This time, I was honored to get this trial on ZEALER, so I had the opportunity to experience the Backstreet for the second time. The author is a mountain bike enthusiast, not a serious enthusiast. He has also struggled with four mountain bikes in a small way. He still has his own opinion on riding. This time, the 700bike Backstreet delivered goods during the National Day holiday, but the author who returned home only started unpacking him yesterday. It happened that we also met with rainy weather, so a wonderful experience began. Today, the author will tell us his experience through four parts.

Part I: Unpacking&Assembly;

When I was in my hometown, I received a phone call from the courier who said that the delivery arrived and asked my colleague to sign for it. I understood that the packaging should be split, but I got a big box by consulting my colleague over the phone. This was really unexpected. The express delivery staff of Shunfeng Express said that the express delivery fee would cost thousands of yuan. Fortunately, the author didn't pay for the express delivery fee.

The huge package, together with my mountain bike, should be the sample paper of the finished vehicle packaging. Unpacking the package, I saw the appearance of a whole vehicle in front of me.

The packaging was fairly good. Every part was well protected. There was also a small box with instructions on accessories and tools. Because of the packing, the cross and foot pedal will still be removed from the back street. You need to install it yourself.

Wellgo pedal is used in Backstreet. It happens that the current diy mountain bike of the author also uses this brand pedal. This brand has good cost performance and performance. Although the products of this brand are entry-level pedal, at least this brand has a good reputation in China.  

Installation part: First, we install the foot pedal. There are left and right labels on both ends of the foot pedal. Please take your seat according to the number. It is worth mentioning that the thread direction of the foot pedal is opposite to the normal thread direction. This is designed to better prevent the foot pedal from falling off and causing danger during riding. Screw in the throat by hand and tighten the foot pedal with the hexagonal socket.

Install the horizontal handle. The horizontal handle is commonly known as the tap. Loosen the vertical handle screw, put the horizontal handle in the middle, cover the cover, adjust the angle and position, and tighten the screw to complete the horizontal handle installation. It is important to note that the screws should not be used too hard to avoid the failure of the handlebar due to the slipping of the screws. From unpacking to the completion of the assembly of the above two parts, the product can basically be used normally.

In order to use the product better and more safely, we also need to adjust and sort out some special parts. First, the bowl set part. There are three operation hangtags in the 700bike back street, one of which is unclear. What we need is to fine tune the bowl set rather than install the whole set, so our operation should be as follows. Part ① does not need to be screwed, Loosen ② and fix the direction with the hexagonal socket, and then use the opening tool provided to tighten part ③ clockwise. Tighten ② when the direction is not loose.

The proper height of the seat is conducive to comfortable riding, so we need to adjust the length of the seat tube. Unscrew the bolts in the following figure to adjust the seat. It is recommended to put the seat tube in place at one time to avoid scratching the seat tube and affecting the appearance.

Then, check the tire pressure. The air nozzle in the back street is the French air nozzle; The French air nozzle is mostly used in road bikes, which has the advantages of small size and strong sealing. The disadvantage is that most of the US mouth gas cylinders are used in China, so the switch nozzle is needed to meet the traditional gas cylinder pumping.

This is the end of the first part. It is worth noting that you should read the manual before installing the new car to avoid misoperation. You can only go on the road after checking each component for potential safety hazards. Pay attention to regular maintenance of products.

Part II: Product details;

700bike Backstreet is a derivative urban product between off-road mountain bikes and road bikes. If you want to say that the most attractive place for me is the shape design with design inspiration. The uniform appearance design will suddenly make you feel that innovation can make you shine.

We don't want to repeat the part of the official display too much here. You can go to the 700bike official to enjoy the high-definition large picture without code. Here the author selects some special features to talk about.

Backstreet has made good use of the characteristics of bicycles and integrated intelligent elements into bicycles, The vertical embedded system includes GPS GSM、 The electronic components of the Bluetooth module allow you to easily Learn your cycling data, Panasonic Power Flower Drum Provide power support for interactive devices The front wheel low resistance Panasonic generating flower drum is equipped with 2600mA 18650 built-in large capacity battery, Provide sufficient power supply for on-board interactive equipment.

Although the design is very ingenious, in the actual experience, as a senior cyclist, the integration of appearance is obviously not enough, and the lack of internal comprehensive cooperation is not enough. It can be said that the Backstreet has a good intelligent foundation, but has made the worst interactive interface. Next, start the time of complaining.

The author is a senior cyclist and also an enthusiast of intelligent wearable products. What we need to see on the stopwatch is what information. I need to see the real-time data of cycling. What items are included? First, the current speed must include the time and mileage of a single ride. After a ride, I need to see what my average speed is, how long it takes, and how far I have traveled. Advanced functions include stepping frequency rate, temperature, heart rate, etc. The information displayed on the large display screen in the back street is monotonous and not very useful. The information displayed is only time, speed, mileage, signal, etc. There is no manual key, and manual scrolling is not supported. That is to say, this screen can only be viewed but not used. Speaking of which, let's say (tu) (cao) about the APP matching the Backstreet.

It is very interesting to be able to combine the bicycle with the mobile phone that is always around every day. 700bike Backstreet has achieved this very well, and a SIM and GPS module are integrated in the display component to realize the anti-theft alarm of the Backstreet advantage If he is only used as a burglar, he obviously makes a mountain out of a molehill. If you bought a bicycle of more than 2000, do you have the heart to put it out of your sight and only rely on the alarm device to ensure safety? Practical experience tells me that I can't do it. How many riders lost their cars right under their noses. The bloody lesson reminds the author that today's thieves and robbers are almost the same. And don't expect jc to help you locate and search. No more words, more words are tears. Go back to the Backstreet APP. First of all, the connection problem always prompts that there is no connection, but the data can be transmitted. Since there is no actual impact on the author, I don't care so much about him.

Let's talk about the functions of APP. At first glance, it seems to be an interface of an intelligent bracelet. It is similar to the content displayed on the dial. There is an additional statistical and calorie conversion data for viewing, as well as the anti-theft positioning function entrance of the artifact, which can "lock the car" with one key like the car (not really locking the car but just turning on the alarm system). It's very cool. There are also some interactive elements in it. You can share the little data you have with your friends and perform mileage PK with people you have never met before. Then there is no then...

When it comes to the APP, there are many complaints. If there is no way to display more information on the dial, it should at least have the basic data collection function of the bicycle code meter. The APP is still so simple, and the software engineering needs to be refueled. These are just algorithm problems in software. It should not be difficult to do them. Let's talk about the positioning function again. If it is just for anti-theft positioning, it is obviously a bit of a storm in a teacup. The indoor positioning accuracy depends on the gprs positioning error of the SIM card to be more than 50 meters, and there is basically no way to achieve accurate search. Imagine expanding the function, and using the GPS positioning function to draw the motion track of each path. When you return home, you can see where you have walked every day and share it with your friends. Use the location function to meet friends at a designated place. When we ride, we often have some friends who want to ride together halfway, and then can't figure out our position. If we can mark the position at this time, it will be very simple and convenient to find. If the next generation can be upgraded, the dial can display the map for navigation. In this way, we can solve the needs of our car friends. In short, what needs to be done on the first generation backstreet is the most basic function of an ordinary code meter. The next generation of products hope to use the positioning system to achieve more user-friendly and fun functions.

Other detailed introductions about the Backstreet are officially detailed in the high-definition no code large picture. Here, the author talks about the rare internal transmission system on bicycles. If you are a senior cyclist, you will know that the transmission system is currently most widely used by the two brands "SHIMANO in Japan" and "sram in the United States". The transmission kit of DIY is SHIMANO XT; Now I think we should use speed couplets. Well, don't go too far. The flower drum used in the back street should be the sram i-motin series automatic internal speed change flower drum. The two gears switch automatically according to the speed. It is especially suitable for lazy people and crowded urban roads.

The solution for chain dropping - eccentric central shaft, which can be adjusted without special tools to adjust the chain tension It also greatly reduces the possibility of chain dropping.

I still feel a lot of design features on the 700bike back street, such as the h-type rear upper fork, eccentric center axle, power generation flower drum, and stab resistant tires of the internal transmission kit. Anti slip pedals and so on are city bikes that have passed the entry-level label since they were born on the back street. What kind of bike can you buy for more than 2000 yuan? That must be entry-level!

Part III: Cycling performance test;

A good bicycle should be comfortable to ride, easy to climb, stable and not stiff when crossing the ridge, and the frame should have a certain shock absorption capacity. Another important thing is to have a high "appearance". If you want to ride out like a vegetable cart, you can't keep your face up. Fortunately, your appearance is good in the back street.

Because there are many mountain bikes to ride, there are few city bikes to ride. There is no shock absorption of mountain bike's recoil front fork in the overall riding. The hand is slightly numb in bumpy road sections, the seat cushion is relatively comfortable, and the frame size of 178 L size is just right; The author tried to speed up to 40 yards, saying that it was difficult to achieve, and the frequency of pedaling around 35 yards was already very fast. It's a bit unbearable at 40 yards. In order to test some basic characteristics of the 700 bike back street, the author has done four tests: braking distance, climbing ability, water release and rejection ability, and the ability to pass the sill and eliminate earthquakes.

From the video, we can see some conclusions. If you are lazy and unwilling to watch it, then the author will simply make a summary of the four parts of the test. First, the brake system. The V brake is used in the back street. The braking distance of 30 is around a car body, which is slightly inferior to the disc brake. The advantage is that it is lighter and easier to maintain. The braking effect is very good. Although the internal speed change flower drum of the hill climbing speed coupler is only supported by the second gear on the hill climbing, it is more selective than the bicycle that cannot change the gear. 70 ° breaking can be easily carried out with a little help of a certain impact force. The ability to prevent water splashing is very important to the author. In order to attract passers-by's attention, generally, some high-grade bicycles will not be equipped with mudguards. It is inevitable to encounter rainy wetlands. Then a good drain tube is particularly important. The performance of the backstreet in the time experience was very good. It happened that the author came back from the vacation and encountered light rain. The road was wet, and the speed was kept at about 25 yards. There was no trace of water splashing behind the unit. The fourth part is the ability to pass the ridge. The official said that the h-type rear upper fork has a certain shock absorption ability. In fact, I can't feel it personally, but the overall performance is very comfortable, and it has a certain rebound ability if you pass the ridge.

Part IV: Summary; Product experience&car purchase suggestions;

The National Day was originally a good opportunity for cycling, but I went back to my hometown for some personal reasons, so that the 700bike back street was not opened for a long time. Fortunately, I am a true cycling enthusiast. With six years of cycling and DIY experience, I obviously have some advantages in cycling experience, For Backstreet, this is defined as a derivative product between mountain bikes and road bikes - city bikes. Still have their own personality.

First of all, the first impression of 700bike on the packaging and assembly is that it is considerate. The operation guidance of the small tag provides technical support for junior users. So that Xiaobai can also get started quickly. But then again, although he has good technical support in the factory, can the after-sales service in the future be solved well? This is also a big pain point for online e-commerce companies, but fortunately, the maintenance cost of the whole vehicle is not too high through visual inspection, so it is just the process of replacing the tire casing and oiling.

These days, I have been riding to and from work on the back street. The overall feeling is that the hard fork is still numb. The handle of the leather handle cover is still very good. If I want to use the secondary gear change for racing, it's OK. I feel a little tired even after I reach 35 yards. The reason for tiredness is that the pedal frequency is too fast and the energy consumption is too fast. The project of code meter detection is relatively weak, and there is still a lot of room for optimization in the later software. We also hope that engineers will pay more attention to it. At least the function to be achieved is a code meter. The next generation of products hope to add the manual adjustment mode to monitor different parameters. On the whole, the 700bike back street has the characteristics of a city and is suitable for traveling on congested urban roads. Unique shape design can attract many eyes. It can be said that it has a relatively good pedigree, and the software is improved. The price of 2499 is completely worthy of this price. As for the car selection, the author suggests that if you are a true cross-country enthusiast, then choose a mountain bike with good safety performance; If you have the ultimate pursuit of speed, a lightweight road bike is your best choice; If you just want to have a companion who belongs to your own minor life and is a transportation tool for urban life, the 700bike Backstreet is your best choice. Elegant, with strong urban atmosphere and a little bit of intelligent life.

Finally, let me remind you that this article does not elaborate too much on the parameters and advantages of the Backstreet. The reason is very simple. I just want to use a senior cyclist to give some personal comments on the 700 bike Backstreet. I hope it will be helpful for your shopping. Finally, I will send you some pictures and rewards. Hope you like them. More support!
