Bicycle speedometers: what are they, how to choose and install?

Cycling is actively developing, and the popularity of bicycles is growing so rapidly that the thought creeps in: cars are about to fade into the background. A huge number of useful gadgets are created for cyclists, among which the speedometer is in the first place.

A bicycle speedometer is a measuring device that determines your travel speed and distance traveled. This information is useful for many cyclists, especially athletes.

The bicycle meter provides a person the ability to improve the physical abilities of your body, evenly increase the load on the muscles and bring the main indicators to perfection.

The bicycle market offers a huge selection of speedometers. Despite the great variety of these devices, all models are divided into three large groups.

Mechanical instrument is becoming less popular, but still it still finds its consumer. Typically, these models are installed on road-type bicycles. For mountain sports, mechanics is contraindicated, since it quickly fails due to dirt and sand that gets on the device. These speedometers consist of only three parts:

• frame;
• cable;
• drive wheel.

Pointer speedometer it is important to install correctly so that there is close contact between the tire and the wheel. The mechanic has a number of disadvantages that lead to a decrease in its popularity:

• impossibility of functioning with deformed wheels;
• inability to save information for its further analysis;
• in case of incorrect installation, constant braking is observed;
• vulnerability to pollution;
• the need for periodic lubrication.

Positive aspects are also typical for such devices:

• high reliability;
• affordable cost;
• autonomous operation, which does not require the use of third-party power supplies.

Electronic speedometer is the choice of many cyclists. Its design is more complex than that of mechanical models, it consists of the following parts:

• the main unit is mounted on the steering gear;
• connections;
• the cadence sensor is fixed to the connecting rod;
• high-speed is located on the frame;
• the wheel sensor is attached to the fork.

Electronic speedometers differ in the number of functions, which is a determining factor in the formation of value. The basic set of functions includes the definition of the following indicators:

• current time;
• the duration of the trip;
• mileage;
• speed (current, average, maximum possible);
• pressure.

Electronic models are becoming more affordable than many cyclists are using. They are easy to install and easy to use, so they are great for novice users. Disadvantages are also present here:

• limited number of functions;
• high degree of wire wear;
• reliable fixation is required for stable operation;
• the need for periodic replacement of power supplies.

The wireless cycling computer is the state-of-the-art used by avowed cyclists.... A radio channel is used to transmit a signal - this is the main feature of such devices. Batteries or built-in rechargeable batteries can be used as batteries, but such models are much more expensive.

Such devices have a wide range of advantages:

• determination of three indicators of speed;
• built-in clock, stopwatch;
• high level of moisture protection;
• synchronization with a computer;
• altimeter and cadence;
• backlight;
• determination of the pulse;
• calculation of the lap time;
• high strength, reliability and durability;
• accuracy;
• saving information about previous workouts;
• no need for lubrication.

Wireless cycling computers are not ideal, they also have disadvantages:

• the need to replace batteries;
• the presence of GPS is typical only for expensive models;
• electromagnetic interference (ignition coil, telephone, power lines) can interfere with the normal operation of the measuring device;
• high cost compared to other types of devices.

You cannot buy the first speedometer that comes across, which you liked by its appearance or attractive price.

Our rules will help you make the right choice, which you will not have to regret in the future.

1. You need to think carefully about the set of desired features. There is no point in overpaying for options that are not useful. At the same time, it is convenient when everything you need is in one device.
2. Sporty driving, high-speed driving, driving in difficult conditions - all this requires the choice of an advanced model with excellent reliability and wide functionality.
3. Bicycle speedometers must have a sturdy housing that is highly resistant to moisture.
4. The backlight must be present in models that will be used at night.
5. The external interface should be user-friendly. This indicator is chosen in accordance with the personal preferences of each.

Almost every speedometer has its own installation rules, but in general, all practical guides are similar.

The most difficult thing is to install a bicycle computer, therefore we took this process as a basis - using it as an example, we will consider the main stages of such work.

You need to start with the installation of the mounting platform. It looks like a panel with two contacts. This part is fastened with a lock. Different locations can be selected for the installation of the mounting plate:

• the edge of the grip is usually chosen by avid gadget fans; with this arrangement, the user receives a lot of advantages;
• the center of the handlebar is the most common choice for most cyclists;
• bicycle handlebar stem is more suitable for large devices.

To fix the mounting pad, bundles are used, which must be strongly tightened and reinforced with substrates.

Mounting the magnet and sensor requires the location of these parts at a distance of at least 8 cm from the wheel axis. This work requires caution. To fix the sensor, harnesses are also used, and the reed switch must be placed perpendicular to the axis of the magnet. The magnet itself is attached to the spoke, near the reed switch (the distance cannot be more than 2 mm). The magnet must also be tightened.

Wire location - complex process that takes the most time. You can use one of two methods here:

• if you place the wire along the brake cable, then ordinary electrical tape is used to fix it;
• when laying the cable over the steering column, it is necessary to use harnesses, and in the area of ​​the frame, make a lap.

Many manufacturers are engaged in the production of speedometers for bicycles. Which company to choose and which model to choose are eternal questions for cyclists. Our review will help you understand the existing range.

• Among all manufacturers that produce bicycle speedometers, the first place is occupied by the company Sigma. No one will undertake to argue with this. The assortment is divided into several categories, which are designed for different levels of the user, his requirements and financial capabilities. These gadgets are created in Germany, which already determines their high quality. The cost is appropriate, but these devices will serve trouble-free for many years.

• Company Garmin is not inferior to the previous manufacturer, offering cyclists high-quality and multifunctional devices. Such devices are produced in America, they are expensive, but they serve almost forever. The assortment is so rich that it will not be difficult to choose a suitable model for a bicycle with alloy wheels.

• Ciclo Is another worthy manufacturer located in Germany. Despite the high quality, excellent reliability and wide functionality, the company offers many affordable models. Ciclo bike speedometers are becoming the choice of many users at different levels.

• Although one should be wary of Chinese manufacturers, there are worthy brands here too. For example, products from the company LIXADA has established itself on the positive side. A wide range of devices are presented for every taste and financial capabilities. For 900 rubles, you can pick up a decent speedometer with backlight, calorie counter, high moisture protection and other useful functions.
