Bicycle computer: how it works and how to choose the most suitable model

The fans of active rest did not have time to dream about installing a speedometer on their bike, as the rapid development of engineering thought once again decided to surprise them with their new invention. However, if we take into account that our time is called the age of information and mobility, then the bicycle computer ceases to seem something outlandish and unusual. Iron horse as a means of transportation and a tool for practicing a useful sport is increasingly appearing on the streets of the city, and the data reported by the cyclometer (this is another name for such a device) can be useful for both beginners and professional athletes.

How a bicycle computer works

The vast majority of modern models for obtaining information about movement use a magnetic counter, the main parts of which are two small magnets. One of them is attached to the front wheel of the bike, and the second - directly to the fork. Thanks to him, the bicycle computer receives information about the number of perfect complete revolutions of the wheel. In order for the device to correctly determine the distance and other parameters, the user pre-sets the diameter of the rim in the settings.

How to make the right choice

If you read about what is written on this topic on bike forums, then you can easily get confused. Some cyclists recommend a wireless bicycle computer, explaining this by the fact that it can easily be removed if you have to leave your transport on the street. Others emphasize durability and recommend purchasing proven models. In particular, very many positive reviews are left by those who use the Sigma bicycle computer. At the same time, I want the device to be as functional as possible. Experts advise to select the model individually, based on the way of riding and the tasks of the future owner. For example, those who prefer a mountain bike, it is recommended to buy a basic rugged bicycle computer, capable of determining the average and current speed, as well as the distance traveled.

In addition, there are devices specifically designed for this type of bike that can read data at low speed. Professional athletes who are preparing for a triathlon or road racing should choose a more advanced model with a built-in stopwatch, calorie counter, altimeter. Those who love long cycling, for sure, like devices with a GPS-navigator, and those who take care of their health - the heart rate sensor. In addition, there are models with a coding function that allow you to ride a group and not be afraid that your own bike computer will read the data of the fellow traveler. Installation of such a device usually does not cause any difficulties, since most of them are accompanied by a very detailed instruction, and the size of the rim is easy to find out by looking at the marking of the camera under the tire. In order to determine the size of the wheel itself, you need to add the thickness of the bicycle tire to it.
