How to choose and buy bike

With increasing selection of different models of bikes the majority of buyers are unable to choose the right two-wheeled friend.

You need to know the following parameters:

  1. Its growth;
  2. Your weight.

Then you must decide on the style of riding, and depending on this type of bike.

Selection depending on growth. To accurately measure your growth, you have to do it barefoot. Your real growth needs to know in order not to make a mistake in choosing the right size bike.

Picking up the bike, you need to look at dimensional grid of a particular firm. These tables are compiled by the manufacturers themselves.

When buying on the Internet will be useful for design method selection of available sizes. In order to choose the right bike, you will need to measure the height from the groin to the floor, and this value multiply by 0.66 to 0.57 percent for roadies or mountain bike type. Received - this is the length. To convert to inches you need to divide by 2.54.

Choice depending on weight. If you weigh less than 80 kg is not advisable to buy a bike with a long seatpost.

If you weigh more than 80 kg, you should not buy a big fast bike the seat tube because it will be difficult to cope with such a bike, you will tire quickly, and high speeds on this bike to develop you will not succeed. It is preferable to hire mountain or city bike. On these models you will ride in a more upright position, and back will become less tense.

Selection of bike depending on riding style and terrain. For the city: city, cruiser, folding bike.

Advice 2: 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.
