Fans of outdoor activities have not had 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 century of information and mobility, then the bicycle computer ceases to seem something outlandish and unusual. The iron horse, as a means of transportation and a tool for practicing the most 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 to both a novice and a professional athlete.
How does a bicycle computer work?
The vast majority of modern models use a magnetic counter to obtain information about movement, the main parts of which are two small magnets. One of them is mounted on the front wheel of the bike, and the second - directly on the fork. Thanks to him, information about the number of complete full revolutions of the wheel is received in the bicycle computer. In order for the device to correctly determine the distance and other indicators, the user pre-sets the rim diameter in the settings.
How to make the right choice
If you read what they write about this topic on bicycle forums, you can easily get confused. Some cyclists recommend a wireless bicycle computer, explaining that it can be easily removed if you have to leave your transport on the street. Others focus on durability and recommend purchasing proven models. In particular, a lot of 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 choosing a model individually, based on the riding method and tasks of the future owner. For example, for those who prefer a mountain bike, it is recommended to buy a basic robust bicycle computer that can determine 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 trips will surely like devices with a GPS-navigator, and those who care about their health will like a heart rate sensor. In addition, there are models with an encoding function that allow you to ride in a group and not be afraid that your own bike computer will read the data of a fellow traveler. Installing such a device usually does not cause any difficulties, since most of them are accompanied by very detailed instructions, and the size of the rim is easy to figure out by looking at the marking of the camera under the tire. In order to determine the size of the wheel itself, the thickness of the bicycle tire must be added to it .
