How to choose a wireless bike computer?

The bike computer is gaining great popularity not only among bike lovers, but also among professionals. How does this device work and what is it like?

A bicycle computer, regardless of model, is equipped with a Hall sensor, which detects magnetic radiation. A magnet is fixed on one of the front spokes, a reed switch is opposite it, which closes the contact each time a magnet passes by it. The signals are transmitted to a computer and displayed on the screen in the form of numbers. Some bike computer models can additionally calculate the cadence per minute (cadence). To do this, install another magnet on the connecting rod, and a sensor sensitive to magnetic radiation - on the back feather.

There is a wireless bike computer that works wirelessly, and the signals from the sensor are transmitted over the air. The basis of all calculations is the number of wheel revolutions per minute. All data is calculated based on this value. The main measurement parameter is the current speed. These data let the rider know how fast he is riding. The bicycle computer also shows the maximum speed with which the cyclist moved during the trip, the average speed (the ratio of the total distance to the time of movement). Besides, in some models you can set the desired speed - if this indicator decreases, the bike computer will notify you.

What else does the bike computer show:

• total mileage;
• distance traveled in a certain time;
• the number and distance of segments of the path;
• time;
• stopwatch;
• the time that the bike was in motion;
• countdown;
• cadence (current and middle frequency);
• heart rate (on some models);
• ride height.

In addition, for ease of use, they are installed:

• ambient temperature sensors;
• backlight;
• remote buttons that can be installed in any place convenient for you;
• synchronization with PC;
• the ability to change the size of information displayed on the screen;
• sound signals.

There are two options for a bike computer - wired and wireless. For a wired signal, it comes through the wires connecting the sensor and the computer itself, while the wireless one uses a radio channel. Each species has its own advantages and disadvantages.

Among the advantages of a wired bike computer are:

• low cost;
• no batteries required for operation.

Minuses:

• installation on a special stand is necessary;
• wires can be damaged during extreme driving (for example, in the forest).

Wireless models have the following advantages:

• works even if removed from the stand;
• lack of wires.

Minuses:

• high price;
• additional batteries are needed (for long trips you will need a spare set of batteries);
• incorrect operation within the city due to strong radio interference (in this case, a wired bike computer is better).

Any bicycle computer has general requirements that should be oriented to purchase:

• convenient screen (readings should be clearly visible while driving);
• waterproof (this will allow you to ride even in rain or fog);
• shock and vibration resistance;
• reliable fastenings.

Standard equipment includes:

• special panel for fixing;
• a magnet on the spoke;
• reed switch;
• wire (if the model is wired);
• auxiliary clamps for fastening;
• instruction, warranty;
• sometimes spare batteries;
• cadence (some models).

The standard option allows you to find out the distance traveled during a bike ride, average ride speed, minimum and maximum speeds.

More professional models come with a heart rate monitor, cadence sensor, stopwatch, built-in thermometer, carbon dioxide sensor, etc.

Bicycle computers are divided into 3 groups:

• simple - suitable for ordinary motorists and beginners;
• advanced - for athletes;
• advanced - professional.

Simple devices show basic functions:

• speed (currently, maximum, for the entire ride period);
• travel time;
• distance traveled;
• total mileage (from the start of installation);
• clock.

This option is suitable for most cyclists. Among the budget models, the Ventura X of Chinese manufacture can be distinguished. The accuracy of indicators does not exceed 1%, shockproof housing, waterproof, the screen is well read. The set of functions is minimal, all results after changing the batteries are reset, the odometer is designed for a distance of up to 999 km. This model is more suitable for those who need a bike computer more for reference. Those who want to know their sporting successes need to pay attention to more advanced models.

Models of cycle computers from the advanced series have additional features.

• Calculation of the average speed on a certain section of the path. This indicator is useful for comparing speed in training or when calculating hiking time.
• Some models are equipped with a counter remaining kilometers. This feature will be needed by sports cycling enthusiasts, especially in “wild” places.
• After changing the batteries, all settings and data are saved.
• It can work on two bicycles, there is a memory function for each of them (suitable for those who have 2 different models of cycling).

A popular model from this category can be called Sigma 1609 STS. The device, in addition to the above functions, has:

• display backlight for convenient use at night;
• battery level indicator;
• heart rate monitor;
• it is possible to synchronize with a PC for analysis of indicators;
• second bike recognizer;
• automatic recognition of the beginning and end of the path;
• thermometer;
• cadence control function.

This model is suitable for athletes.

Advanced bike computers can calculate, if not everything, then a lot. Different derivatives are added to the standard indicators, such as:

• number of calories burned (when entering body weight);
• kilometers that you need to drive to burn the required number of calories, etc.

The most popular bike computer is the Sigma ROX 10.0. The model is expensive (more than 10 thousand rubles), but it is almost a personal sports doctor, weather station and navigator at the same time. In addition to the above functions, this bike computer will help you plan and analyze your workout, evaluate energy and more.

Before buying, you need to decide on the following questions:

• what data do you need while riding a bicycle;
• what budget do you expect;
• what additional features you might find useful.

The choice of model also depends on what type of cyclists you belong to.

• Lover - you use a bicycle for outdoor activities or prefer this type of transport to move around the city. 3 characteristics are needed - speed, time and distance.
• Advanced - Spend all your free time on a bicycle, prefer cycling, sporting events, etc. The indicators of total mileage, maximum height, maximum and average speed are important.
• Athlete - constant training. You need an analysis of workouts, heart rate, cadence, calorie count and more.

Next, you need to choose the type of bike computer - wired or wireless. The wireless option should be preferred if your bike rides often take place outside the city, where there is a high risk of damage to the wire, there is radio interference.
