Type

The type determines, first of all, the method of communication with the remote wheel speed sensor. Recall that most bike computers are equipped with such a sensor, it is mounted on a fork, and a special magnet is attached to the wheel; when the wheel rotates, the device detects the passage of the magnet past the sensor and determines the revolutions by their frequency. The connection options are:

Wired. The advantages of a wired connection are low cost, reliable connection, and the fact that the speed sensor does not require its own battery. And the battery of the computer itself with such a connection “lives” longer than with a wireless one. On the other hand, such devices are somewhat less convenient to install than wireless ones, and in case of an unsuccessful fall or collision, there is a risk of breaking the wire.

Wireless. Such a connection allows you to do without unnecessary wires, which greatly simplifies the installation of the bike computer. At the same time, it costs more than a wired one, and two batteries are used in such a system — in the computer itself and in the speed sensor, and you will have to monitor both. Also, if there are many other wireless cycling computers nearby, the connection may fail.

Cadence

Cadence display functions provided in this cycle computer. Note that these functions require the installation of a separate sensor, which is not always included in the package.

Cadence is called the frequency of pedaling (pedaling). This information can be useful, in particular, for choosing the optimal gear and for evaluating the overall effectiveness of the training. The cadence should not be too low (this increases the load and wears out the knee joints) nor too high (this leads to rapid fatigue). Its optimal values may be different, depending on specific conditions; information about this can be found in special sources.

In addition to displaying the current cadence, cycling computers may have a function to display the average cadence (usually for a trip) and the maximum cadence (for a particular period, depending on the model). This data can be used for a variety of purposes, mainly for professional athletes and keen enthusiasts.

Number of lines

The number of lines on the screen of the bike computer.

In this case, only lines intended for displaying basic data are meant — values of speed, time, etc.; strings for service characters are not taken into account. Thus, the number of lines is the number of parameters that can be simultaneously displayed on the bike computer display: for example, on a two-line screen, you can see the current speed and ride time. And in some models, there may be two parameters per line. The lines themselves in most bike computers are two, less often — three or four, it makes no sense to use more.

Functions

Slot for memory cards. Slot for removable memory cards, most often in microSD size (specific supported varieties may be different, they should be specified separately). Such maps not only expand the built-in memory of the bike computer, but can also be used to exchange data with other devices: for example, using such a carrier, you can upload GPS trip tracks to a laptop or download navigation maps from the same laptop. This feature is found mainly in advanced models.

Impact protection. The presence in the device of enhanced protection against shocks and concussions; in some models, increased resistance to vibrations is also claimed. It is worth noting here that any bike computer is made with the expectation of shaking and jolts that inevitably occur when riding a bike. Therefore, shock protection usually means increased durability, allowing you to endure not only standard road shaking, but also extreme use like downhill or cyclocross. At the same time, it would not hurt to clarify the specific degree of such protection separately.

Water protection. The presence in the device of enhanced protection against moisture. The specific level of moisture resistance in different models may vary, it should be clarified before buying. However, this feature usually means at least the ability to endure being in the rain without consequences, and often more adv...anced capabilities, up to short-term immersion in water. So for those who intend to ride regardless of the weather, it is highly desirable to choose waterproof bike computers.

Connecting to a smartphone. The ability to connect the cycle computer to a smartphone — usually via Bluetooth (see "Sensors"). Theoretically, it is possible to connect with other gadgets, but the smartphone, unlike them, can be used on the go (mounted on the steering wheel or just kept with you). Connecting to a smartphone can include many different functions, their set should be specified separately. One of the most popular options is “live broadcast” of data from a bike computer to a fitness application on a smartphone, or even to special social Internet services for training.

Connecting to a PC. The ability to connect the bike computer to a PC or laptop. The classic way to use this feature is to download the data collected by the bike computer to a PC for further processing. Note that the connection itself can be carried out in different ways: some models use a simple USB cable (usually included in the kit), others use a wireless adapter that must be purchased separately.

Mount on the hand. The ability to mount the bike computer on the user's hand. This feature is found exclusively in wireless models (see "Type"); usually, a special strap is used for this, purchased separately. For some users, this mount is more convenient, and in extreme driving it can be even more reliable than a standard handlebar mount.

Calculation of calories. The function of calculating the calories expended by the user. Note that devices with this feature do not measure actual energy consumption — they calculate the number of calories burned based on speed, distance, altitude difference, heart rate, etc. The result is approximate, but perfect accuracy is not required in this case.

Building a route. A feature that is found exclusively in models with a GPS module (see "Sensors"). Usually, it involves connecting to a PC and building a route on the map in a special application, after which this data is loaded into the bike computer — and the user can follow the route, receiving hints about directions from the device screen. And after the trip, you can upload the actual route with the results of the race. Some models with this feature even have integration with “social” sports services that allow you to share routes and compete with other users.

Automatic start-stop. Function of automatic start and stop of measurements. Models with this function turn on at the start of movement, when the speed sensor gives the first signal, and turn off (stop recording parameters) some time after stopping. This saves the user from having to turn on/off the cycle computer manually.

— Clock. The presence in the cycle computer of its own clock. This means not just a time counter that allows you to record the time of the trip, but a full-fledged watch that displays the current time of day. In addition to general convenience (the ability to find out what time it is at any time), this function has more specific applications: for example, the clock tracks the change of day when counting the daily distance traveled (see "Indications").

Timer and stopwatch. Opportunity of work of the bicycle computer in the mode of the timer and a stop watch; usually both of these possibilities are provided, so they are combined in this case. These functions differ from travel time readings (see "Indications") in that the countdown can be started and stopped at the user's command — usually by pressing a button. A stopwatch can be useful, in particular, for measuring the total travel time, taking into account all stops; timer — for counting a specific training time.

Battery level. An indicator showing the current battery level. It can have a different appearance and specifics of use: for example, in some models, the charge indicator is displayed on the screen at the user's command, in others it is displayed constantly, usually in the upper part. The indicator readings are quite approximate, but it still makes it much easier to monitor the state of the battery and reduces the risk of running out of charge at the most inopportune moment.

— Non- volatile memory. The presence of non-volatile memory in the cycle computer. Various information, especially measurement data, is stored in such a memory even during power outages — for example, when removing the battery or discharging the battery to zero.

Fuel economy statistics. "Ecological" function, designed mainly for those who are worried about the preservation of the environment. Allows you to estimate how much fuel the user saved by riding a certain distance on a bicycle instead of using a car. However, environmental awareness is not limited to: data on fuel economy can be a powerful motivation from a financial point of view.
