1. bicycle mileage watch price

The price of cheap mountain bicycles may be one or two hundred yuan, but if you want to buy one, you can receive a Step frequency, speed, heartbeat sensor, and another GPS trajectory recording function.Can make people break the glasses.

2. The characteristics of the bicycle -specific code watch

The special code watch of a bicycle is actually a very practical accessory. The simplest code watch can display the speed and time in real time in real time. The additional additional functions may help you calculate the mileage and time of a single driving.

Simple entry -level code watch ranges from 100 yuan to 400 yuan. If you deliberately find a wired code watch, maybe you can get it within 200 yuan, but it is a bit ugly.

Third, the price is expensive.

To put it simply, the more expensive the slogan, the more functions, and the more functions may be so that you don't know how to use it.You can communicate with your mobile phone, you can communicate with a bunch of APPs, you can connect with a lot of sensors, and display the information of riding in real time. These are just "obvious" functions.Most of the sensors, such as stepping frequency, speed, power meter, and ANT and Bluetooth dual -frequency receiving, basically there is no signal of the sensor.The performance of this code watch is already the top level.

Fourth, is it necessary to buy road bicycle codes?

1. Powerful recording ability

If you plan to conduct efficient training in a scientific way, professional code tables must be indispensable.The professional code table can collect the message from the sensor, transform the physical energy into the actual data, and can also export these data to analyze it in other ways. This is the biggest difference between the expensive and cheap code table.The price of a code watch with a price of about 1,500 yuan to 2,000 yuan, or even the price exceeds 2,000 yuan, in addition to integrating peripheral sensors, the additional added value lies in the "record" ability of the device.

2. Not only records, but also analysis and operation

Some expensive code tables can not only display information such as stepping frequency, heart rate, power and other information in real time.At the moment of the record, it will be completely recorded by the code watch. This information is actually meaningful for data analysis.If you just use information such as speed, frequency, heartbeat and other information when riding a bike, in fact, you only use a small part of this code.

3. navigation function

The main function of the Bicycle code watch positioning system is to accurately locate the coordinates of the signal device. The Bicycle code watch with satellite positioning does not even need to rely on the speed sensor. You can calculate your movement speed by positioning the satellite alone.The function of satellite positioning can usually ensure the accuracy of the trajectory records, and these systems are also applied to navigation devices for vehicles.Because there is a satellite positioning, the possibility of adding navigation functions to the code watch is given. As long as the code watch is added to the map of the road, it can be navigated with a certain airpoint operation.Essence

1. The working principle of the Bicycle code watch

The principle of the bicycle sheet is that the sensor captures the information brought by the inductive magnet when the car ring rotates, transmits it to the gauge through the sensing line, and the host code table is calculated to calculate the speed, mileage and other information after this process.

Popularly speaking, there is a magnet -like thing on the front wheels. There is a sensor on the front fork. The wheels turn around, and the magnet passes through the sensor once.In the wheel parameters, the code watch has calculated the speed and the journey.To put it simply, the airflow formed during the cycling process to generate induction of the wind hole of the code watch, thereby measuring the speed.

2. What is the reason for the Bicycle code watch

The bicycle codes are not allowed

1. The code table generally has only two keys. The "SET key" in the back is the setting key.Hold down the "SET key" behind the code watch for more than 2 seconds, and enter the setting mode after the screen displays "Set Open".

2. The screen displays "SIZE 2155", where the wheel value is set.Press "Big Key", the screen display "Unit Kmh", that is, the display value is "km/h".

3. Press "Big Key", the screen shows "Dist 0", which is the total mileage.Press "Big Key", the screen displays "time 00:02", that is, time.

4. Press "Big Key", the screen display "Scan OFF", that is, the scroll display mode is turned off.

5. Then go back to the "Time" interface, press the "SET key", the numbers flickered, and set the numbers according to the "Big Key".

6. After the time is adjusted, press the "SET key" again, the screen display "Set OK", and the time settings are successful.

7. Press the "SET key" behind the code watch for more than 2 seconds. The screen displays "SET Close", exit the setting mode, and then press "Big Key" to switch to time and check the setting time.

The average speed of the bicycle codes is not allowed

The biggest reason for the inaccurate speed of the bicycle codes is the incorrect setting of the perimeter of the wheels. Generally, the newly -bought bicycle sheet wheels need to be set. You need to accurately measure the size of the car, and then the code watch parameters follow the car circle according to the car circle.Settings.

The highest speed of the Bicycle code watch is not allowed

There are many reasons for the highest speed of the Bicycle code watch, but the reason is basically the same, that is, the wheels of the wheels have vibrated when the magnets of the front wheels pass through the sensor (sanitary Tube) through the code watch, such as overwhelming over the wheel, such as overwriting too much.A pit, a sudden brake, etc., made the magnet shake near the sensor of the code watch, so that the code watch thought that in this shaking time, the front wheels had turned around, so that there would be a very high high.Speed and recorded, this is normal, don't care.

Common fault inspections and maintenance of bicycle code tables

1. Check whether the distance between the magnet and the induction switch meets the requirements. If the distance is too far away, it will affect the accuracy of the speed.

maintenance method: adjust the distance between the magnet and the induction switch to the right distance.

2. The contact point of the code watch and the circuit on the seat is dirty, causing poor contact.

maintenance method: Use fine sandpaper to polish.

3. Check whether the connection line of the induction switch to the code table has internal disconnection, resulting in intermittent interruption.Checking method: Dial the multimeter to the "RX1" file, and the red and black surface needles are connected to the two electrodes on the codes. At this time, the front wheels should be turned, and the pointer of the multimeter should be swinged left and right.

maintenance method: The induction switch is normal and the connection is normal; if you do not swing or dial the line gently, the intermittent time is open, there is a breakpoint of the connection, and the connection line needs to be replaced.

4. The above are normal. Please check whether the battery of the code watch should be updated?Using the universal DC voltage V10, the battery voltage for various tables may be different.

maintenance method: As long as the measured voltage is below 60%of the original battery voltage, the battery needs to be replaced.For example, the LR44 twist battery should be 1.5V. If the measured is & lt; 1.0V, the same type of battery needs to be reduced.

5. The code watch may enter the water, causing internal line failure.

maintenance method: Open the rear cover and put the code watch for about 30 minutes at 10-20 cm from the incandescent lamp, but pay attention not to be too close, due to the high temperature damage circuit.

6. If the LCD screen of the code watch is black.

maintenance method: It means that the code watch is damaged, then you need to change the new watch.

7. Because the magnetic body of the bicycle watch is installed on the barrier, it is often in a fast rotation state, and it is often easy to change or even fall off due to touch, collision, and rubbing.

maintenance method: If it is lost, it can be self -made.The method of repairing the bicycle code is as follows: Find a small magnet (such as a magnetic door touch and a small magnet in the Headset, with small size, strong magnetic force, light weight light), a small aluminum Skin, a bottle 502 502Powerful glue. First cut the small aluminum Skin with scissors to 15X20mm; Then fold it on the position of the bar that needs to be installed (form a U -shaped); Inject an appropriate amount of "502" glue in the middle of aluminum Skin and magnets, so that the magnets and aluminum Skin are firmly stuck (about a few minutes); Adjust this magnet up and down to the right position, and inject "502 ".After drying, adjust the position and position of the induction switch, that is, the sue is successful.

1. Wired or wireless on the riding code watch

Wired code table

The wired code watch is mainly used to transmit the sensor signal through the data cable. It is the most commonly used code watch type.

Advantages: The performance is relatively stable, the speed of the speed is more accurate, and it is not easy to be disturbed. As long as a small battery can work, the electricity consumption is very low, and the price is usually cheaper.With luminous effect.

Disadvantages: The installation of a wired code watch is relatively troublesome, and it affects the beauty of the overall car.

Wireless

The wireless code table is actually an external sensor and magnetic head, but it does not need to use the data cable to transmit the model and directly receive the wireless reception.

Advantages: The installation of the wireless code table is relatively simple and convenient, and it does not affect the overall beauty of the car. The sensitivity of the sensor is stronger, and the functional design is more diverse and intelligent.

Disadvantages: Although the high -quality wireless code watch is accurate, the price is relatively high. The general price of the wireless code watch with a general price of less than 100 yuan is inaccurate and the performance is unstable. It will often be disturbed during use.

Through the introduction of the advantages and disadvantages of the bicycle wired code watch and wireless code watch above, you can buy according to your favorite and purchasing focus.

Second, the main point of buying the bicycle gauge

What parts need for cycling code

1. Together: It looks like an electronic timer, with LCD display, keys, metal contacts, etc., is the most important part of the code watch

2. table seats, connecting and sensors: The table seats are usually placed in the car's handle or stand to the head to fix the header.There is a connection on the wired table seat, connecting the seat seat with the sensor installed on the front fork.The wireless code watch has no connection, and the sensor transmits data to the header by transmitting wireless signals.

3. Sensing magnet: The spokes installed on the front wheel, the position is maintained with the sensor installed on the front fork.Essence

4. Poor frequency (non -standard accessory): The mid -to -high -end watch has the function of calculating the frequency, that is, the frequency of the driver's pedal.Common stepping device includes connecting, sensors, and induction magnets. The connection is used to connect to the sensor that connects the table and the triangle installed in the back triangle of the frame (the rear triangle here isPipe), induction magnets are often installed at the crank, the position corresponds to the sensor, and the working principle is the same.

5. Synthetic lighting (non -standard accessories): Installed on the table to illuminate the watch at night.

What are the quality of the Bicycle code table?

1. Accuracy of calculation: Ride information as much as possible.

2. Qualification of workmanship: It will not produce poor contact contact, easy connection to break, and no display on the head.

3. A certain degree of Earthquake resistance: Don't make a strike at a bumps.Of course, the bumps with too strong strength will also overwhelmed many code watches that usually perform well.If you are often engaged in high -intensity off -road, it is recommended to choose a code watch designed for this, and this code table will be mentioned later.

4. A certain degree of waterproof: riding outside, it is inevitable to encounter the situation of rain ride.If the precision electronic products encounter internal water, it will cause the product to fail, and the product will be scrapped.For example, waterproof fabrics have a certain waterproof index, and the code watch should also have a certain waterproof function.However, in the case of heavy rain, no matter how good the code watch you use, it is recommended to take it down and put it in a waterproof bag.

How to buy the Bicycle code watch

1. Select the required display parameters

A Bicycle code watch should at least be able to accurately display three sets of parameters: speed, mileage and time.Single -block surfaces can be obtained through GPS and presented on the screen, and the wireless code table with Bluetooth connection can be installed, which can be more accurate through peripheral peripheral peripheral peripheral peripheral peripheral peripheral peripheral peripheral peripheral peripherals to measureValue.Select the functions required according to your own needs.

2. Choose the right brand price

The price of a bicycle gauge ranges from tens of yuan to thousands of yuan. The huge price difference makes many novices who have just entered the pit.Don't be too tangled with brand and complicated functions, the cost -effectiveness is the first place.If it is a road idiot, it is recommended to buy a code watch with navigation and map functions.

3. Choose your favorite operation method

bicycle code tables generally have two types: touch screen and keys. You can choose according to your own operating habits. Before buying, you can see if it is a full touch screen, double -key, three -key or four keys?The fewer keys, the simpler, but the response speed and the screen touch are not comparable to smartphones. On the contrary, although the button is effective, it is often too hard to press.The head drops it from the shelf.And once the codes go out at a high speed, I am afraid it will be worth it.
