Bicycle computers: device and functions, rules for selection and installation

On-board computers for bicycles are by no means a surprise given the speed of technology. Their main task is to make the control of a “smart” bike as simple as possible and at the same time safe. The original version of the devices measured only speed and mileage, but today the number of technology capabilities has significantly increased, which allows it to be used in various fields with the highest possible efficiency.

Today, an on-board bicycle computer is used not only by athletes, but also by those who prefer to travel by such transport both in city limits and on rough terrain. Everything runs on small batteries that need to be changed several times a year, depending on the model. The computer itself and all its components are attached to the bicycle, and a magnet attached to the spokes of the front or rear wheel transmits the necessary information.

Depending on the model the magnet and the sensor are connected with each other by a wire or by means of a wireless radio signal.

If we talk about practical benefits, then a bicycle computer allows you to record such results as:

• current and average speed;
• set speed;
• distance for a certain period of time or all the way.

All this information is very useful for athletes and travelers.Some models also contain cardiac functions that indicate the average and maximum heart rate or the difference between the values ​​\ u200b \ u200bfrom the specified range.

A bicycle computer is a specialized device that consists of several parts. The principle of its operation is quite simple, all information is transmitted using a small magnet and a high-precision digital signal. In fact, several basic types of on-board computers can be distinguished.

In this case, the kit includes a magnet and a fixing device that measures the results. They are connected to each other with a special wire. The main advantage is the ability to save battery consumption; it needs to be changed no more than twice a year.

This option differs from the previous one in that the wires are completely absent, and information is transmitted using a wireless radio signal. But such a model can work intermittently in urban conditions, where it is necessary to take into account the appearance of extraneous interference in the radio phone. In addition, the energy consumption of such models is much higher, and the batteries will have to be changed more often. There are also very compact models that are carried out in the form of a wristwatch and is very convenient for athletes, so as not to be distracted from the road on the way and measure the results.

In addition to the basic functions, the kit may include a number of additional options at the request of the user. This, as a rule, affects the price, if it does, then insignificantly. The number of the main functionality varies from 5 to 25, and the additional one provides a more comfortable ride in any conditions.

Models with a GPS navigator are ideal for travelers to navigate unfamiliar terrain... Outwardly, they are slightly different from the usual Google Maps, but users figure out the features pretty quickly. The technology itself is interactive and convenient, and the pointer to the target will quickly determine the best route for the trip. In addition, navigation can help you find your lost bike if needed.

Computers with a cadence sensor allow you to load the entire area, down to the location of houses, trees and main streets. But it is worth considering that to do this, you need to connect it to a laptop or tablet computer, you can also use a special application on your smartphone.

It will be useful for athletes to track their own condition models with a heart rate monitor, which can be found literally for any level of finance. Wireless devices quietly take direction finding using bluetooth or radio signal, of course, such models are more in demand for travelers and people leading an active lifestyle.

Sunding SD-563b - a well-known model of a bicycle computer, the kit includes a bracket for mounting on the handlebars, a set of several ties, a magnetic sensor and a magnet. There are more than 20 declared functions of this device, and there are several unique features.

• Liquid crystal display with automatic backlighting. All information is displayed in several lines.
• The weight of the sensor is compact - no more than 30 grams.
• Dimensions do not exceed 57x40x18 mm.
• Rugged, waterproof housing.
• Battery charge indicator.
• Even an inexperienced user can understand the installation and operation of the device, and as for the functions, they contain everything that a cyclist may need: a speedometer for measuring speed, the ability to measure the total mileage since the device was started, the ability to record the highest speed and total time,spent on the way, the function of counting down the travel time and fixing the speed of movement in all its sections.

The Garmin bike computer also has many features. For example, the fact that for work it is recommended to create an account in a special application. With Connect software, it will be possible to record the results of training statistics. Also, thanks to this, you can create universal training programs with a USB flash drive included, a usb input with connecting additional devices. Certain changes have taken place in the design of the menu, there are more pages and it would be easier to switch to the necessary settings.

Cyclotech - a bicycle computer with a protective case and a fairly simple mounting option. The functionality of this device is as follows:

• travel time;
• total mileage during use;
• maximum and current speed;
• energy saving mode.

The Cateye is a rugged and reliable computer that can operate in multiple modes. Providing high functionality and fine tuning, the user can use the computer with maximum performance. Installation and fastening is simple and intuitive, this computer is suitable for all types of bicycles.

On Stern bicycles you can move not only within the city, but also over rough terrain. And the bike computer installed on the model will help to effectively record the distance traveled, speed and other features of the path. Clear digital metrics encourage you to keep going and help you create an individual training program for each user.

Lezyne is a bike computer programmed with a number of interactive functions, thanks to which it can work on several protocols at the same time. Thanks to the simultaneous synchronization, the user receives all available information not only about speed or power, but also about heart rate. The computer perfectly tracks the electronic transmission and records all the results in real time.

If the user needs an accurate calculation of the average speed, distance traveled and travel time, then Stels is the ideal choice.... The bike computer is equipped with all the necessary functions and is affordable for literally everyone. The dimensions of the device are quite compact, and it can be used in combination with any bicycle model. At the same time, setup and installation are intuitively clear even for novice cyclists, and, if necessary, the instructions will answer all the questions posed.

The general setup is to determine the circumference of the bicycle wheel, usually in millimeters. It is on this stage that the accuracy of calculating the speed and distance traveled depends, therefore it is very important to set the required values ​​in the system. Usually all numbers are given roughly, and it all depends on the manufacturer's instructions. The distance traveled is also influenced by the condition of the road surface, tire pressure and the weight of the cyclist.

To purchase a suitable on-board computer for your bike, you need to pay attention not only to the design or brand, but also to several important nuances:

• what information the user will need on the trip;
• what amount is acceptable in the selection process;
• what additional functions or options will be required during use.

For those who are more active in sports, and use a bicycle not only for walking, much more information is needed. For example, the minimum and maximum speed of the bike, the time it takes to pass a certain section, or the acceleration time from the start point to the end point of the journey. In this case, you will need more professional on-board computers that can satisfy the given requests.

Installing an on-board computer on a bicycle, regardless of the brand, begins with attaching the device. In general, there are three main locations:

• center of the steering wheel;
• bracket;
• grips around the edges.

Most often installed exactly in the center, since in this case the computer is protected by a frame and does not touch the cyclist while driving. It is worth noting that for the accuracy of the measurements, when installing a highly sensitive device, you can install it even on alloy wheels. The device is fixed using special harnesses, which must be tightened as tightly as possible. They are provided by the manufacturer in a set, as well as a rubber backing for the work monitor, to avoid slipping during use.

Setting up the computer begins only after installing all the components, after the monitor, a magnet and a sensor are attached to the bike. In this case, the sensor is turned towards the magnet so that the signal is received with the required accuracy. And the magnet itself is installed on the needles. All this should be located at a right angle, after which the position of the device can be fixed completely. The wheel on which the sensor and the magnet will be installed does not matter for the measurement accuracy. But most often all components are installed in the front.

After the installation has been completed, you need to configure the device. To do this, just reset the basic parameters to the "default" level and restart the computer. After that, you can safely start using.

If you want your gadget to serve you for a long time and without interruptions, it is very important to pay attention to the technical condition... At least periodically inspect your transport for reliable fastening, safety of the main components and parts, as well as correctly established indicators. Pay attention to the fastening of the magnet on the wheel, the condition of the brakes and steering wheel. The surface of the brakes must be clean and, in the case of an automatic brake, the reaction must be visible immediately after the pressure is applied.

The position of the steering wheel also plays a significant role, it should be perpendicular to the front wheel. If necessary, the height is adjusted, but always taking into account the limiter. It is also worth making sure that there is sufficient lubrication. There is almost no need to monitor the operation of the computer itself; it is enough to reset the parameters to the "default" state several times a year and make sure that the necessary drivers are updated on time.

Adjusting the brakes ensures that they are applied accurately and on time. And this is what affects their service life. If a wired computer is installed on the bike, you will also have to monitor the condition of the wires.

Magnetic bike computers with sensor - one of the cheapest and most compact options... But the owner definitely needs to monitor the state of the reed switch, where all the small parts are located that ensure the operation of the mechanism and interaction with the magnetic field as a whole due to a closed electrical circuit. This choice is understandable even if you need to purchase something with a minimum of energy consumption. Particular attention must be paid to enclosures against dust and moisture.
