Indications

Readings that can be displayed on the cycle computer display.

Current speed. Displays the speed of movement at a given moment.

Average speed. Display of the average speed of movement for a certain period, usually from the beginning of the trip to the current moment. The computer calculates this speed using the formula "total distance divided by total time." Note that in such calculations, only the time in motion can be taken into account, without intermediate stops (except for the shortest ones).

Maximum speed. Displays the maximum speed reached for a certain period — for a trip, for a day, for all the time since the last reset, etc. The specific features of this function in different models may vary, they need to be specified separately.

Ratio current/average speed. The ratio of the speed of the trip at the moment to the average speed for the entire trip. This function allows you to evaluate the current pace of movement and compare it with the pace in the already passed section.

Current distance travelled. Displays the distance traveled since the start of the trip.

Daily distance travelled. Displays the distance traveled for the current day. The change of day of the model with this function i...s monitored by its own clock (see "Functions").

Total distance travelled. Displays the total distance traveled since the last reset of the cycling computer. In some models, it may be possible to reset this counter without a general reset.

Current travel time. Displays the time elapsed since the start of the current trip. Usually, the countdown starts from the moment the movement starts; during short stops, it can continue or be paused, these points should be clarified separately.

Total travel time. Displaying the total time spent in motion for a certain period — usually since the last reset of the bike computer settings (or resetting this counter separately, some devices have such an option). Usually, only the time in motion is taken into account, excluding intermediate stops, with the exception of the shortest ones, up to half a minute to a minute.

Touch screen

Touch screen — similar to those used in modern smartphones. Allows you to control the cycle computer by touching the image on the display.

Such control itself often turns out to be more convenient and visual than traditional buttons: you can display a variety of controls (lists, switches, sliders, etc.) on the screen, as well as explanations for them, which allows you to make the most of the device simple and intuitive. In addition, touch screens are extremely convenient for maps and navigation.

In general, it makes no sense to install touch screens in simple devices with basic capabilities, but they can be very useful for advanced models with extensive functionality. However, even among these models, touch displays are rare, due to a number of reasons. Firstly, for comfortable work, the screen must be quite large — however, even in the most advanced bike computers, its diagonal usually does not exceed 3.5", and in some it does not even reach 2.5". This is quite a bit for a touch screen. Secondly, it is almost impossible to work with the sensor by touch — unlike the buttons; and the probability of accidentally clicking “in the wrong place”, especially on the go, in this case is much higher. Thirdly, it is difficult to work with such devices in closed-type gloves (without cut off fingers): such gloves must have special inserts on the fingers, and the accuracy of pressing decreases noticeably — which can be critical, given the already mentioned small screen sizes.
