Simple bike tachos guide
Now the most important questions about the bicycle speedometer are clarified.
Why should I buy a bike speedometer?
The bike speedometer shows you after a bike ride your kilometres ridden. So you know what you have achieved! You can see values like your geared kilometers, your average speed and the ride time. Total kilometers the bike speedometer also shows you.
So you have the overview and can be proud of how much you have cycled in the year. With the displayed information, you can also better manage your forces.
Inexpensive bike computer: These functions it has
- Daily kilometres / Total kilometres
- Travel time
Bike speedometer with cable or wireless: The differences
A cheap simple bike computer often transmits the signal via cable. Many manufacturers offer their models each as Bicycle speedometer with cable and as Wireless bicycle speedometer.
The following features, advantages and disadvantages are offered by the technologies in the bike computer.
Bike speedometer with cable – advantages and disadvantages
Less power consumption and you only need one battery (with the wireless bike computer the receiver needs an extra battery)
✅ Reliable data transmission without interruptions
✅ A bike speedometer with cable is cheaper than a wireless bike speedometer
✅ Battery life usually significantly longer than one year
The bike speedometer mounting with cable takes a little longer, because the cable must be laid additionally. The cable is led from the top of the bicycle speedometer down to the sensor on the fork.
You can mount the speedometer or the speedometer mount on the handlebar or on the stem.
Bike speedometer wireless – advantages and disadvantages
Very simple and quick assembly
✅ Tidy look on the bike without cables
✅ Reliable and wireless data transmission between bike speedometer and transmitter
✅ Very long battery life: Usually well over a year
❌ slightly more expensive than bicycle tachos with cable
❌ Two batteries required: 1x in the bike speedometer and 1x in the transmitter
Mounting a bicycle speedometer correctly
A bicycle speedometer is quickly mounted on the bicycle. The mounting differs slightly from model to model and for the bike speedometer with cable, the cable must also be laid from the bracket on the handlebars to the sensor on the bike fork.
In general, assembly takes less than 10 minutes and is usually possible without tools. This is how you get your odometer on your bike ready to go:
Fixing the bike tachometer bracket: The bracket can be attached either to the handlebar or to the stem. The bracket is attached to the bike with either cable ties or rubber O-rings. Sometimes an adhesive pad is included as a mounting aid. The mounting of the bracket also works wonderfully without this tool.
Laying the cable from the bike speedometer to the sensor (only for bike speedometers with cable): For bike speedometers with cable, the data is transferred between the bracket and the magnetic sensor via the cable. This cable must now be laid. Either you run the cable over the stem, to the frame and then to the bike fork. Alternatively, you wind the cable spirally and evenly on the brake cable down to the fork. This solution provides a tidy appearance. In addition, you always have enough cable available even at maximum handlebar angle. With the first mentioned solution (stem, frame, fork) you have to take care of the correct length of the wheel speedo cable yourself.
Fix the magnetic sensor to the fork: The sensor is located at the end of the cable and is also supplied with power via it. With the wireless bike speedometer, the battery for power supply is in the sensor. Of course there is no cable with the radio bike speedometer. The sensor is attached to the bicycle fork with rubber O-rings or cable ties. Pay attention to the correct alignment of the sensor: between sensor and spoke magnet may usually be a maximum of 5 mm distance. Therefore, the sensor should be directed towards the front wheel spokes.
Attaching the magnet to the spoke: The magnet is usually located in a plastic sleeve. This cover is simply clipped to a bicycle spoke and holds there securely. In order for the signal to be read, the spoke magnet and sensor should be at the same height.

Correctly adjust the bicycle speedometer
After successful assembly, your bicycle speedometer is as good as ready for use. The data transmission between sensor and wheel speedometer is usually already set up at the factory.
Now the wheel circumference still has to be adjusted correctly. This is the only way to ensure the correct calculation of speed, distance and other bike data.
Many wheel tachos already have presets for the common wheel sizes. However, these presets are quite inaccurate. Better you set your bike speedometer correctly yourself.
There are three ways to do this:
Calculate wheel circumference correctly with formula ( U = 2 * pi * r )
✅ Measure wheel circumference directly
✅ set the bike computer correctly with table
All three methods are shown in detail and easy to follow in the Correctly Set Up Bike Computer article.
Bike speedometer or rather bike speedometer app?
There are now many good cycling apps. I also sometimes use my smartphone as a bike computer. The large touchscreen is a lot of fun to use and there are some excellent bike navigation apps. In comparison, however, there are some disadvantages with a smartphone:
❌ The battery life is much shorter and you have to make sure that it is charged when you start the ride
❌ Operation with the touchscreen display is more cumbersome
❌ The display can not be read in the sun
❌ The touchscreen cannot be operated at all in the rain or the smartphone even breaks down
Still want to use your smartphone as a bike speedometer? Then these articles are useful for you:
