You will need
  • the idea of picking a bike, the skills of selection and Assembly of equipment
Instruction
1
First of all, you need to develop a drawing of the manufactured bike. It is better to use ready-made drawings that Amateurs and craftsmen hang out on the Internet. If you have design skills, you can create a drawing yourself.
It is very responsible on the bikee, manufactured by calculated wrong drawing, skating would be impossible. In addition, if you incorrectly calculated the load on some joints will have excessive load. This will lead to the accumulation of metal fatigue fracture or fractures at the joints of parts. Or, to put it simply, the bike will fall apart at the most inopportune time for you.
2
Keep in mind that you can make at home wheel and chain mechanism with the driving and driven gears is not possible, so all these details you will in any case have to buy.
After you took possession of your drawing, carefully it carefully. For the frame you will need a metal tube of different diameter. Get the right material and start to implement each element separately. Check the workpieces for defects and cracks.
Manufactured elements are connected in a single whole with the help of spot welding.
3
For the manufacture of plugs you will need a press to install the small size and gas welding. You can use the forge and tools designed for forging metal.
When the frame and fork are almost ready, you will need to drill holes for the leading "stars" in frame and mounts wheels in the frame and fork. The holes must be strictly perpendicular to the longitudinal axis of the frame and located parallel to each other.
4
Then you need to make the steering wheel go, leather saddle with seatpost, pedals. Fasten all parts to the frame, hang the chain mechanism, wheels, a braking device. You can now start testing.
If the technique adequately kept on the road, it does not lead to the side, the pedals rotate fine without any additional effort, the Bicycle again to disassemble and prepare for painting.
If riding discomfort or detected any problems during the tests, you need to find and eliminate possible causes. Repeat this procedure until until the bike will not be well established and properly operating as a single mechanism.
5
But why hold yourself to such difficulty, when it is easier to buy ready-made parts and assemble this bikewhat you want?
You can build the best easy option. Buy titanium, or if budget does not allow, aluminum frame. And hang it components, according to their own perceptions of price and quality.
Rims for wheels, spokes, tires, tires, Cams, steering stem, steering column, steering wheel, hard or soft plug, brake pads, brake cables, brake handles and the like less important details – all this can be bought separately and are not dependent on each other.
Than comfortable like this "designer": at any time do not suit you or the defective parts can be replaced with a new one, bought at the local bikeMr. the store or ordered over the Internet.

You can determine the size based on different distances of the frame. It may be the distance from the top tube to the centre of the carriage, the distance from the middle of the carriage to the end of the pipe under the saddle, and also this can be the length of the seat tube. Since most manufacturers indicate the approximate dimensions you should first focus on personal experience, having tasted the convenience of the bikeand myself.

Advice 4: How to choose the Internet speed

With the advent of technology in communications, the transmission speed has reached a new level. Fiber optic cables capable of providing insane data transfer speeds. Often it turns out that high speed is not justified and worth the extra money. It is important not to fall for marketing providers and decide what exactly you need.
How to choose the Internet speed

In order to take into account all the nuances when choosing a fare on the Internet, you need to know a few facts about network operating principles that will help you to use the services more efficiently.

Megabit and megabyte are two different things. 1 Mbps is approximately 8 times more than 1 MB/sec. It turns out that having the Internet speed 8 Mbit/sec, we obtain a real rate of about 1 Mbyte/sec. Music track is of size 5 MB download (fully or see) for 5 seconds. Thus, knowing their needs in the network, one can calculate the time that will execute a particular task at the current rate.

The final speed of the Internet is determined not only by your ISP. On its performance the most important influence factors, such as network equipment, the speed of the remote server, the wireless signal, speed of the target device and so on. If your provider proudly announces 50 megabits per second, while watching movies online you just don't get that speed, because the computer with the movie somewhere. Server downloaded distribution of this film to several thousands, and even tens of thousands of users.

This is comparable to a wide pipe through which flows a small stream: the source (server) more are not able to give, and all the extra space empty. A similar situation occurs if you are with the tablet through 2 walls and a layer of furniture from the router - speed Wi-Fi channel will fall, and no matter how fast Internet to your house has not been received, to the device he will be there at lower speeds.

An important indicator of the quality of communication - ping. In fact, ping is the speed of data access on the Internet, i.e. how fast is the query. If at high speed the ping is large, it will not grow: the queries will be slow. Particularly negative high ping affects normal web surfing, where each click is a request, as well as on online games where the ping depends on the synchronicity of what is happening in real time.

One of the most frequent and demanding user tasks - online video. If the music's not so important, because the size compositions is small, then with the video you should always pay attention to the capacity in which you watch it. The higher the quality the slower buffering (primary testing) of a film or video. For example, the quality of 480p requires almost twice lower speed compared to 1080, although many reputable sites automatically set the video quality, so the problem was not so significant.

Torrents - the best speed test. Here, as servers are the computers of the users, and upload speed information on your computer is aggregated for all servers. As a result the overall rate of return can be very large, capable of loading any Internet channel.

Considering all these factors, it is possible to make the following recommendations.

  • about 5 Mbit/sec is more than enough to surf the web while listening to music, and the Internet channel can share multiple devices with such tasks
  • 10 Mbps can ensure the smooth FullHD video playback on 2 devices, and the third quite comfortably browse page
  • 20 Mbps this speed that will allow you to watch a FullHD movie with concurrent torrent download and channel you can still safely hang the phone with the tablet and comfortable to watch Youtube. For correspondence and web surfing speed are unnecessary.
  • 40 Mbit. Such speed of the older routers just don't support it. Needless to say, 40 Mbps will be enough for all. To recommend it only to users with special tasks, e.g. FTP-server or work with files in the cloud systems. You should not take such a speed, if you're just listening to music, texting, the Internet and sometimes watch a movie. It will be an overpayment.
  • 60 Mbit/s and above. Yes, at present, some providers offer these numbers and really need them very rarely. It happens that the provider promises the night even 100 Mbit/sec and above, but to support this speed need an expensive powerful router and "Gigabit" cables. Almost all mobile devices will not be able to open up at that speed, and the computer will need either an expensive motherboard with a 1000mb network card or Gigabit network card.

Given the average requirements of the Internet users in modern conditions of Internet speed of 15-20 Mbps is sufficient for almost all tasks. Often, large numbers enter users into believing, as if promising that "everything will be fast." But providers know that used to be only a quarter of those 60 Mbps, so in fact You put 15-20 Mbps at a price of 60. Most often the difference is felt only when running torrent clients, but for most users this is hardly worth the overpayment.
