Installation cycling on a bike. Nuances of proper tuning cycomputer Installation of cycling 26

In the previous article, we considered questions about and what to pay attention to.

Now consider how to install it correctly on the bike.

If you bought a GSM-cycle computer or use a smartphone with an appropriate program for these purposes, there is no special installation issues.

For a smartphone, it is generally easier to buy a special compartment on top for its installation or additional attachments for phones.

GSM-cycomputers included are special platforms for fastening on the steering or removal. If necessary, they can also be found on the Internet.

In extreme cases, put such a computer or smartphone simply in your pocket or bag - it will still count everything, just the results can be viewed only at the stop or after the trip.

The main installation issues concern only magnetic cycomputers.

They are two types: wired and wireless.

The main principle of operation of both types in counting the number of wheel turns. Then, knowing the length, the number of revolutions and time, the computer calculates all other parameters: the distance traveled, speed, time in the way, etc. etc. Some models consider and remember up to 50 different parameters.

How the wheel turnover is considered.

These are engaged in the kit: the germ, installed, for example, on the leg of the anterior plug, and a magnet that is secured on the spokes of the wheel.

What is the German and the principle of his work.

Gercon (hermetic contact) - This is an electromechanical device in which contacts, closing, are hidden in hermetic flask electric chain When exposed to a magnetic field.

When you turn on the computer and start a trip, the contacts of Hercon are open. At the time of the passage of the magnet, fixed on the needle, the contacts are closed past the motionless germe, and the computer considers one turnover of the wheel. The wheel was checked further - the magnet left the Herkeon. The magnetic field ceased to influence its contacts - the chain open.

Based on the understanding of this mechanics, there are basic requirements for the installation of a magnet and heroke.

Consider them in turn.

What should be the distance between magnet and armor

Depending on the sensitivity of the Hercon and the magnet power, the distance between them should be from 2 to a maximum, 8-10 mm. See the instructions more accurately to your cycle support. Usually put 3-5 mm at a distance.

The magnet should be located in the center of Herkeon if the instructions are not specified otherwise. If he passes past Herkeon above or below - the counter will be wrong.

Similarly, when turning the magnet around the knitting needles. If he "turns out" from Herrock, the testimony will become wrong.

After installation, thoroughly test the accuracy of counting the number of magnet over the magnet and wheel turns. Just twist the wheel manually and see if the computer considers correctly. Please note that the magnet does not rotate the Magnet with the rotation.

In what place to put a magnet on the needker: closer to the rim or to the axis?

Here logic is simple: if you put a magnet closer to the rim, then it will fly past the Herrock, while driving, much faster than if it was located closer to the axis of the wheel. The angular speed of the rim is significantly higher than the axis.

So, at high speeds, Herkeon may simply do not have time to work, and the computer will miss the turnover of the wheel - will begin to give incorrect readings.

Yes, and the distance from the magnet installed in this place the knitting needles to the legs of the fork with the reverence can be significantly larger than the required 5 mm.

Further. When fastening the magnet on the spice closer to the rim, the centrifugal force acting on it is sharply increasing when moving the centrifugal force and the likelihood of external influence of branches, grass, dirt, etc., which can move or deploy a magnet around the knitting needles in relation to the German, and this is again The same will affect the testimony.

Therefore, it is best to put a magnet at a distance of about 10-15 cm from the axis of the wheel. It is necessary to watch on a specific wheel and geometric sizes of the germeron and magnet.

Which wheel to put a germ and a magnet cycomputer.

You can put them as on the front, which makes most often and in the rear wheel.

What is the difference in the installation of a cycomputer on the front and rear wheel?

In fact, the difference is that more accurately considers a computer installed on the rear wheel. The front you tax, it jerks more when traveling around the city and rough terrain and therefore passes a little longer distance than the rear. Also, it is more than the back exposed to external influence on the magnet, as stated above.

The difference in testimony from the front and rear wheels during long trips can reach a few percent. So if you need accuracy and there is a difference: you drove 20 or 20.5 kilometers - put on the rear wheel.

If a good wireless cycle computer is installed, considering also cadence (the frequency of rotation of the pedals), then it both Hercom can be in one case. It is necessary to put it unambiguously on the pen of the rear wheel, so that it can react to the magnet installed on the connecting rod and allows you to consider cadence, and on the back of the rear wheel to calculate the speed.

If the gerons of cadence and speed are made in various housings, then Geron Caednes can be installed either on the bottom of the pen, or at the bottom of the seat pipe.

But at the same time, keep in mind that if you have a wired cycle computer, then the wire to therone will reach through the entire bike. Therefore, first check if it is enough long to reach the rear wheel. And the wireless, there should be enough range to communicate with the computer. Usually for normal manufacturers, this is not a problem, but some Chinese "noname" models work reliably only on the front wheel.

Reception of wireless sensors is described in the instructions.

Where to install a platform for fastening a cycomputer

Fasten it on the steering wheel or ending the steering wheel.

Consider the pros and cons of the fastening places of the platform of a cycomputer:

The main thing in this business is: the location of the cycomputer must be convenient for the biker itself. His it should be clearly visible all the readings and comfortably switch the modes buttons.. Moreover, taking into account what it is necessary to do during the trip. Those. Then, when the bike is trembling and shaking on our practically "ideal" roads.

How to lay the wire to therone

After you clearly decided where you wake a velocomputer on the steering wheel and on what wheel to place the reserves with a magnet, you might think about the wire laying.

The main task is to do everything aesthetic and reliably.

If the reserves are installed on the fork, then the wire is best to put the front brake brake cable with the transition to the foot of the fork.

By a fork, it can be allowed, whining around his leg or on its inside, strengthened the wire with a bicycle color, plastic fasteners or even transparent thin tape. The inner side of the leg is less susceptible to external influences than the outdoor and better protect the wire from the random cliff.

When moving a wire with a cable on the leg, the fork do not forget to leave a small supply to the steering turns. Check that at any turn it does not stretch.

Some bikers, the launch wire on the cable, also spin it around it. It is quite normal, but, in my opinion, is not very beautiful. It is better to still be fixed to the cable with a black tape or a thin transparent scotch. Swirling around the cable wire has " harmful habit"Sliding, spinning and getting up to the side.

The main thing when laying the wire is to check for anything clung to and not sharpening.

What is the best way to fix the gercon and a cycomputer platform: tie or rubber bands?

Elastic bands that come in a set for fastening the platform of a cycomputer to the handlebar or the removal and the Herrock to the foot of the fork, in my opinion, are not always reliable. Especially when traveling through the forest or grass. The hooked branch can disrupt her, which will lead to the loss of Herkeon.

Better, nevertheless, grab everything with reliable thin plastic screeds used for ligaments of wires, which have cut down repellent tips.

When a bike falling, the screed is definitely better to withstand various external influences.

In what order to install a bicycle bike computer

1. First of all, decide in which place the steering wheel will stand the platform with the computer itself.
2. Decide: what wheel the geron with a magnet will be installed on the front or rear.
3. Count, whether there will be enough wires. There are models in which the wire can be trimmed by fixing to the contacts on the platform. In the cheaper wire already soldered into the platform and has a clearly defined length. Usually, it is enough only for installation on the front wheel.
4. When everything became clear, start the installation from fastening the platform on the steering wheel. Just do not attach it right away. First, just fasten to keep, and at the end of the installation, tighten all the mounts completely. The fact is that after laying the wire, it may be necessary to move it a little to the right.
5. If your computer has no changeable lengths, send it as you want: winding the frames and pipes frame and forks or strengthening it to cables and pipes with tape, scotch tape or plastic tie. The main thing is that the wire does not hang out.

   Locking the wire, leave the stock on the steering wheel. At the end of the gasket, install the gercon and magnet on the knitting needles as described above and check that they do not touch each other.

   If the wires are left much, you can make a couple of extra revolutions of the cable tube or twist it into a small cove and fasten with scotch tape or tie on the inside of the fork.

1. If the wire can be trimmed, you first install a magnet with a germ, and then pull the wire to the fixed platform.

   If the wire after the gasket is still left and cut it sorry or it is impossible, then wrap it around the steering wheel and fasten it with a tape, scotch tape or tie.

2. After the completion of the work, check how correctly the Hercon considers the rotation of the wheel. To do this, simply cool the wheel and see how the computer works.

Another nuance - read the instructions for the purchased computer - there are often writing a lot of useful information.

Well, it seems that everything is connected with the installation.

Judging by search queries, the number of people willing to learn how set the cycle computer Pretty great. Therefore, I decided to write comprehensive instructions for installation Velikomputer On the bike.

Install a cycle computer It is not difficult and this task is even a stupid gopnik. Even the tool is usually not required. To begin with, we will define the place of installing the computer. The first thing in the eye is thrown away - it stands in the middle, as if it was created in order for a computer wearing it. But this, I must say, not the most successful idea. Have a standard cycle bunch of different additional features Which also want to observe, but for this you need to switch the modes, and press the button on the cycle component that stands in the middle of the steering wheel is completely uncomfortable, especially in a busty area. Therefore, Krepim Velikomp is directly close to the infrace (handle). He got into exactly the trigger tongue. It does not interfere and you can make the buttons not releasing the steering wheel.
Immediately decides wire protection problem - It is stupidly primed by the tape from the brake cable coming from the fun to the front wheel.

Sensor installation
The sensor of a cycomputer is installed on the foot of the fork from any convenient side. I put on with the right. W. VETTA RT33. Mounting by means of mounting homutics, which in my opinion is very cool. Because These clamps are almost impossible to break, they are easily replaced. The sensor is tightly attracted to the plug tube from the inside. Tightening you need from all my might, because If it crashes from shaking, the computer will stop working. Since the knitting needles are not parallel with the fork, then the sensor mount will be somewhere in the area of \u200b\u200bthe axis, the optimal place for a couple of centimeters on the crossing of the spokes so that the magnet stood straight opposite the sensor and rested himself with his body into crossed knitting needles - then it will not shift the centrifugal force.

Installing a magnet
The magnet is attached to the needles than closer to the sensor, the better. I have the distance from the magnet to the sensor of about 2mm. Tighten the magnet should be firmly, but not excessively. Because There, the thread is cut into the knitting groove, then from a strong tighten it can break or get tension, and then jump from the blow in an unknown direction. I so after tightening the groove gave the silicone sealant. If the screw turns out, the magnet is definitely not lost. The correct installation is checked simply - it is enough to raise the wheel and rotate. After a pair of wheel turns, the computer should show speed. Did not show - catch further.

Fastening wire
The reliability of the velocomputer work depends on the proper installation of the wire. To begin with, you can grab the wire with the screed from the inside of the plug in the interval of twenty centimeters. Why with the inner? Yes, everything is simple, if it is with an external one, then all sorts of branches and other obstacles can easily break the wire. On top of the wire you can stick the scotch band so that it is tightly to make the wire to the fork, then it will not move at all.

In the area of \u200b\u200bthe crown, the wire is securely primed up with a braking cable for which it comes to a velocomp. With this attachment, to damage the wire, it is necessary to try hard, since it is protected from below, and on top of a powerful brake cable shirt.

Configuring cycomputeter

It would seem that there is to configure? No, there is a couple of moments. In any cycle computer must be wheel Size Setup. In the worst case, you can choose one of the standard sizes of rim and tires, in the ideal case, the cycle complex will offer to enter the wheel circumference length in millimeters. The cycle-computer believes the rotation of the wheel, multiplying them on the length of the circumference of the tire, so it is necessary to enter it, and not the circle on which the magnet rotates. Typically, the table length table relative to the wheel and tires is written in the instructions for a cycomputer. If not, the circumference can be taken by a tape measure or a tailor centimeter. Just in case I bring this table Here. Also, any normal cycle computer offers to introduce an initial kilometer. If this is a new computer, then leave zeros there, and if you only changed the battery or already hit a few hundred kilometers, then you can drive the rolled out there.
Still in some cycling technical kilomera. For example in my VETTA RT33. It is denoted by a wrench. If you drive there, for example, 100 kilometers, a wrench will light up every 100 kilometers. Recalling, for example, what to lubricate the chain or carry out the maintenance of the fork.

Possible malfunctions
If a bicycle computer suddenly stopped working, first of all it is necessary to check the velocomputer itself. To do this, it is necessary to rhythmically torture with any metal subject contact plates on its case - there should be some kind of speed.

If the Velikomp itself is working, then checked wire and sensor. For this, an ordinary tester is taken, put on a transvel and connects to the outputs on the panel. After that, a powerful magnet is brought to the sensor. If everything is fine, then the tester will be scored. If not, then you need to look for a wire break. Most likely it will be where it often snars, it is usually in the area of \u200b\u200bthe plug shock absorber. Pierced wire is easy to call if you stick through the insulation thin needles and nick it on slices. There is another way to find a break, but it is more rude and risky. When I broke around the wire, I just took it in the ends (in no case can you take for the sensor and the panel!) And strongly, but carefully pulled. Where there was an open wire, the wire broke out in half :). The torn wire must be cleaned and twisted the vein with a vein, it is advisable to even suck, and then draw them apart from each other and then it's tighten together.

If the computer is working and the sensor with the whole wire, then perhaps bad contact with the computer with the panel. You need to wipe the contacts with a rough eraser, and then rinse with acetone or alcohol.

The second fault type is when bicycle computer begins to lie - overestimate or underestimate speed. Most likely the position of the sensor and the magnet has begun. If the magnet is slightly distinguished from the sensor, then flying by the sensor it calls not one clear and confident triggering, but a frequent rattling that a computer can interpret as very much speed (I once issued a speed of 98 km / h When I barely rolled) or to work One time, which causes a strong understatement of real speed.

Once I had a strange glitch at all. When I rolled away near myself, the speed was shown correctly, but it was worth it to take a bike and go, how a cycleman stopped showing speed at all. Sensor transk showed that it is working. The wire also called. The problem was trivial - the wire was admired inside, but not to the end. And when I sat on a bike, the plug was admitted, the cables were a bit bent and contact in the wire, which was accumulated to the cable, broke.

That seems to be everything. If you have any questions - Velkov in comments.

The cycle computer is very useful, if you ride at least a little further than in the store for bread / to the river to the beach / around the sandbox. Available features differ depending on specific model, but basic set Tracking characteristics can be considered as follows:

• current speed;
• average speed;
• maximum speed;
• current time;
• travel time;
• common traveled path (odometer);
• traveled path of the current trip (since the last reset);
• clock.

Calories, thermometer, pulsometer, Cadence meter, can also be calculated.

If you see during the trip all these parameters, you can control the load not only in sensations, but also by accurate values. Again, it is interesting at the end of the way to find out how many km passed, and on some forum it boasts the maximum speed.

As a rule, the cycle computer is supplied with installation and configuration instructions. But people tend to lose this instruction, and then search on the Internet, how to set up a bicycle computer, what to enter the length of the rim and other similar questions. Therefore, briefly answer such questions.

Installation of cycomputer

The counter is regardless of whether it is wired or wireless, as a rule consists of three parts: the sensor on the front fork, the magnet on the wheel spice, cycle-computer on the steering wheel. Installation sites - arbitrarily, on its own choice. The only thing is that when the wheel rotates the magnet passed close (up to 5 mm) from the sensor. For everything else - common sense to help you! Obviously, it is not good when the wire is chatting (if a wired cycle computer) is naturally attach it to the brake cable and, if necessary, to a fork (tape, tape, wire, mounting ties). The sensor itself to the fork and the computer to the steering wheel is usually attached by tie or special fastening.

Configuring cycomputeter

The main setting is to properly maintain the length of the wheel circle in millimeters. Based on the meter and will calculate the speed and traveled path. You can independently measure this value or see the size marking on the tire and set the value in accordance with the setting table in the wheel size cycle computer (shown on the right).

The values \u200b\u200bare indicative and, if you compare the instructions from different manufacturers, you can see that the wheel may differ for the same size. In fact, the path passed by the wheel depends also on the type of road surface, the tire pressure, the cyclist weight. In addition, any bicycle computer has some error. A few millimeters error in this value does not play.

If you really want to achieve accuracy - configure in accordance with the table, pass on the highway with kilometer pillars several tens of kilometers, compare with the meter reading, based on the difference obtained (if it), make a correction to setting the length of the wheel circle.

Failures in work

At some point, the cycle-computer can begin to climb. For example, the speed is in a flat place to jump to 98 km / h, or fall to zero if accelerated more than 30 km / h. An essential part of such problems is solved by replacing the battery in a cycle computer and / or sensor (in the case of wireless). It is also helpful to make sure that the distance between the magnet on the spin and the sensor on the fork did not increase (due to shaking, dirt, snow, driving in thick grass, etc.). If it is not in batteries, wire or distance to a magnet, then the problem is probably in the board of a cycomputer - independent repair is not subject to if you are not a virtuoso of the soldering iron.

Instructions

In conclusion, several instructions in Russian from different cycompeters ( pDF format, you can download free):

• Ventura X (models 244550 and 244552)

UPD 2015.

Since the initial publication has become very popular "Nainics" and 27.5 ", so I add another sign on setting up a cycomputer. In addition, in case the size of your wheel is not in the plate, and with mathematics, you categorically do not yet be friends, two are given in the picture Methods to find out the length of the wheel circumference, which and must be entered as a tuning of a cycomputer:

sign from the Sigma instruction with typos

The most attentive can notice some difference from the table published earlier. What to say, two centimeters are an accuracy of 1%. Regardless of what captured The value is ideal true real The distance passed in one turn of the wheel will be different (affects the pressure in the tire, the density of the soil, ...). Therefore, the tuning of a cycomputer is always approximate and 1% of the role does not play.

UPD 2016.

The table taken in 2015 from the instructions for the SIGMA cycle service contained, as it turned out, is unabled to a lot of typos (minimum two). Therefore I had to make a sign without these errors with b aboutby the number of already calculated sizes (according to):

If your size is not in the table, here are two simple way determine what value to enter into a cycle computer:

If you already have a bike computer and you went here only in order to learn how to enter ", then you have enough plates above. If you also choose a cycle computer, then read under the spoiler.

Several Chinese cycling computer

I depict the price tags from Baryg in offline stores. It is clear that everyone wants to eat, but sell a penny Chinese device several times more expensive than buying - it is no longer to eat, but "eat". Moreover, it often turns out that cheap cycomputers are not brought at all, but they offer only expensive. I have nothing against Sigma, Cateye products and other famous brands - do great! Their top models for those who are seriously engaged in sports are really good: In addition to basic functions, there are independent timers, stopwalls, a separate pulsometer, an altimeter, a cadence sensor, ... But most amateurs, not to mention the city katapole, all this without need, but in Younger models are significant overpaid for the brand. Therefore, if you really need only data on speed, path and time, I recommend paying attention to the following models of cycomports in the DX.COM.COM.

- A simple "workhorse", knows everything you need, it costs it, unpretentious to the conditions, is easily controlled by a pair of buttons. It feeds on one battery AG13 for a year or two. Communication with the sensor on the wire. In addition to mandatory functions has a thermometer. Instructions for setting, screed for fastening, battery - everything, of course, included.

The last small, but very important question about how to configure it.

In principle, there is nothing particularly difficult in the setting.

As for the issues of setting time and other parameters, we will not particularly stop. To do this, it is enough to read the instructions and properly press the buttons on the computer itself.

The most important thing is necessary correctly enter the length of the circle of the wheel of the bike. And here on this issue will stop more.

In the instructions for any decent cycle supporter there is a table with dimensions.

They also walk through the Internet enough. And you can take values \u200b\u200bfrom there.

At the same time, the most important thing - carefully look at the real size of the tire on your bike. For example, not just 26 wheels, namely 26 x 1.5 or 26 x 1.95. These are different sizes. They differ not only width, but also height and, therefore, its outer diameter.

For example, a tire 26 x 1.5 (40-559) has the length of the circumference of 2010 mm, and in 26 x 1.95 (50-559) the length of the circle is 2050 mm. Those. The difference is 4 cm for one turnover of the wheel.

If you have different tires on the front and rear wheel, and the speed counter stands in the back, then watch the rear tire marking.

There are several more points associated with the accuracy of the tables of the wheel circumference:

Firstly. It happens that the size of your tire is simply not in the attached table.

Secondly. With the same size written on the tire, the circumference is different. This is because different manufacturers Differently take into account the width and, accordingly, the height of the tire. It also depends on the type of coated and the tread pattern - i.e. In the slick and weak tires, the height of rubber is different, hawk width can be the same.

Thirdly. Compare these few tables from the Internet:

Not in all of them, for the same size of the tires, the values \u200b\u200bof the circumference are coincided.

For example, size 23-622 (700x23c) has a circumference length: 2096 and 2133.

Fourth. Well, the Chinese, there are Chinese. How they write instructions, from where the tables take the table only on their conscience and your faith in their honesty and decency.

Therefore, as refers to the data from these tables is the personal matter of everyone. How important it is the accuracy of the instrument readings.

It is because of all these nuances, to measure the length of the circle of the wheel it is your bike, Personally, I recommend using the second way from the article.

For especially lazy, we bring it short here:

For accurate measurement of the length of the circle of the wheel of your bicycle, you need a second person. It will help. The owner punches the desired wheel (front or rear, and best of all) until the usual pressure on which it most often rides and sits on a bike. If the pressure in the wheel is lower or higher, then the size of the circumference length will differ.

When sitting cyclist, measurements will be more accurate, as the tire compression is taken into account during the real trip. Your assistant will put labels on the asphalt.

Next, act according to the following algorithm:

1. In the place of contact with the wheel with an expensive chalk, we draw a thin line on the side of the tire and the road. They naturally have to coincide. It can also be done directly opposite nipple on the wheel - as a natural label.
2. Sitting on a bike, we drive on it in a straight line so that the wheel made one full turn.
3. Where the line on the wheel touched the earth again, we put the second label.
4. We measure the distance between two tags - this is the length of the wheel circumference.
5. To increase the accuracy of calculations, you can make 2-3 measurements and take a medium or drive not one, but three wheel turnover and divide the resulting distance by 3.

Enter the value (in millimeters) to the computer. Usually it is always entered first when setting. Then put on the instructions all other parameters and can go.

In conclusion, I would like to say: do not complex about the accuracy of the calculation of the computer undergoing distance.

The accuracy of the calculation of the cycomputer depends on:

• type Tires - These are slurry or winter toothy with high spikes
• type of road surface - on the asphalt is always more accurate than the soft soil,
• real pressure in the tire during the trip,
• air temperature
• the weight of the cyclist and the cargo transported by them,
• the accuracy of the triggering of Hercon, etc.

Now it needs to somehow install and set up ... He began to dig on the Internet, requests like "how to install a bicycle computer" and "how to set up a bike computer" led to merry manuals. I decided to collect some instructions from them. Although the kit has a completely normal instruction on quite understandable English.

The people write that any gopnik will be able to establish and many brains do not need:

To begin with, we will define the place of installing the computer. The first thing in the eye is thrown away - it stands in the middle, as if it was created in order for a computer wearing it. But this, I must say, not the most successful idea. A pile of different additional functions that also want to observe, but for this you need to switch the modes, and press the button on the cycle component that stands in the middle of the steering wheel is completely uncomfortable, especially in a busty area. Therefore, Krepim Velikomp is directly close to the infrace (handle). He got into exactly the trigger tongue. It does not interfere and you can make the buttons not releasing the steering wheel.
Immediately the problem of protecting the wire is solved - it is stupidly primed by a tape from the brake cable coming from the infections to the front wheel.

I also thought to put it on, but see not a very good idea ...

By the way, for a general case there is such a video:

Pretty understandable. Since my cycle computer is popular among Valvelators, I found and transfer the instructions for him, quite kind of normal.

Installing and configuring a cycomputer on the E-Trail electrobic.

2. Determination of the size of the wheel and setting its value on the display of a cycomputer:

Before starting the cyclist, it is necessary to reset its previous parameters. To reset the testimony of a cycomputer, it is necessary to remove a flat battery from the socket for a short time, located under the cap from the back from the display and paste it back into the socket.

The "2060" figures will appear on the display screen, the first right figure will flash. The specified numbers map the circumference of the bicycle tire. For the correct follow-up measurements of the motion parameters of the electric bike, it is necessary to set the circumference of the wheel of your electric bike. You can do this in the following basic ways:

- choose from the table;

Tire size	Length Districted.
700C x 38mm.	2180
700C x 35mm.	2168
700C x 32mm.	2155
700C x 30mm.	2145
700C x 28mm.	2136
700C x 25mm.	2124
700C x 23mm.	2105
700C x 20mm.	2074
700C Chamber	2130
26 "x 1.75"	2035
26 "x 1.25"	1953
24 "X 1.9"	1916
650c x 23mm.	1990
16 "x 2.0"	1253
16 "x 1.5"	1206
650c x 20mm.	1945
16 "x 1.95"	1257
27 "x 1-1 / 4"	2161
27 "x 1-1 / 8"	2155
26 "x 2.3"	2135
26 "x 2.25"	2115
26 "x 2.1"	2095
26 "x 2.0"	2074
26 "X 1.9"	2055
26 "x 1.5"	1985
26 "x 1.0"	1913
20 "x 1-1 / 4"	1618

- directly measure the length of the wheel circumference;

The wheel size table and the circumference length is approximate as indicated above.

To select the length of the circle using the table, it is necessary to find on the wheel of the wheel of its diameter, for example "26x1.25". In the table we find opposite this diameter corresponding to it the length of the circle - 1953mm and introduce it into a cycle-computer. To enter numbers, press the right button sequentially and set the desired value of the right digit in the circumference length (in our case "3"). Then briefly press the left button. At the same time, the second number of the right to flash is blinking. Similarly, the right button is set to the second digit (in our case, "5") and exhibit the two remaining digits "9" and "1".

The second more accurate method for measuring the length of the wheel circumference:

We apply a white shallow thin, but fat transverse line on the tire (tires must be pre-pumped to normal operating pressure). Next, it is necessary to sit on the electric bicycle and slowly drive through a direct distance of more than one turnover of the wheel, so that the first and second track from the shallow on the tire will be printed on the asphalt or other solid surface (it is better to carry out this operation with an assistant adhering to you when moving). Next, you need to measure the distance between the two risks in mm on the asphalt and enter the numbers in the cycle computer indicated above.

4. Installing parts of a cycomputer to the electric bike.

Installation of parts of a cycomputer on an electric bike is not difficult, it is necessary to show only accuracy and patience.

First of all, it is necessary to pre-consolidate the reinforcement sensor (magnet) as a cylindrical column on the outer spoke of the front wheel. The sensor is fastened with the screw on it, so that you can move the sensor with a small breath force when choosing the desired position.

At the same time, the end of the sensor, with the magnetic part, should be addressed to the reading device, which is to be fixed on the fork.

A reader (motionless) device of a cycomputer is set to the inside of the pillar (pen) of the front plug of the electric bike using velcro and additional mounting with two plastic homutics.

If there is a disk brake on the front wheel, the reader is better installed on the rack, opposite from the brake disc.

When choosing a place of attachment of the reader, it is necessary to proceed from the fact that the distance between the sensor end and the reader when the wheel rotates should be in the range of 0.2-0.3 cm (the end of the sensor should move opposite the central part of the reader).

Having settled the distance in the range of 0.2 - 0.3 mm, then you need to finally fix the sensor on the spoke and the reader on the fork. At the same time, with the final tightening of fastening plastic clamps on the reader and fastening screw on the sensor, the distance between the reader and the sensor should increase to 0.5-1.0 mm. This will be the right working distance between the sensor and the reader for the Sundding cycomputer.

The display of the cycle computer is better to set closer to the steering center. The display fastener is mounted using velcro and is additionally fastened with two plastic homutics.

<>Before fastening the display fastener on the steering wheel, it is advisable to pre-pave the wire from the reader to the display of a cycomputer so that with any steering rotations, this wire remains free and without tension. Next, the wire from the reader is additionally fastened with flexible plastic homutics in the right places.

Fix the display of the cycle computer on the fastener.

Congratulations!

Operation on the installation of a cycompeteer on the electric bike is completed.

If before that you installed everything correctly, then the cycle computer will begin to issue an indication when the front wheel is rotated.

Here is such a teaching instruction for installing a trottery sunding.
