speedometer for a bicycle
1. The common Speedometer for a bicycle meter is divided into wired code meter and GPS code meter.
2. Wired code watches are made in China because they are cheap and easy to use. They are widely used in all kinds of bicycles. After fixing the magnetic head and wired sensor conveniently and simply setting the parameters of time and rim circumference, the wired code meter can be used. Generally, the current speed, average speed and maximum speed can be recorded; Current time and riding time; There are many data such as this riding distance and cumulative riding distance. Basically, after a button battery is installed into the meter, you don't have to worry about the code meter. Therefore, the wired code watch is the most popular bicycle accessory in Europe.
3. There is also a wireless code table connected via Bluetooth. The function is the same as that of wired code meter, except that the sensor and meter are connected through Bluetooth technology. The advantage is that there is no need to wind and bind the fixed line; The disadvantages are high power consumption and high price. It's not expensive at all. The problem is that the power consumption is too high. The button battery of the Bluetooth sensor is replaced every three days. It's not easy to buy the battery. It's mainly troublesome. Therefore, few riders like to use Bluetooth wireless code meter.
4. Another common code table is GPS code table. The header is positioned by receiving signals from GPS satellites. After simply setting the time, you can use it. It is the simplest and most convenient code table to use. GPS code meter has more functions than ordinary wireless code meter. It can cooperate with special frequency sensor and heart rate band to become a tool for professional training and competition. If you cooperate with professional analysis software, you can also carry out professional training and data analysis according to the rider's state.
5.If you simply use the GPS code meter, the domestic code meter is very good. The price is not expensive. If you want to use the professional training function of GPS code meter, you can only buy imported goods. For example, Jiaming's GPS code meter is the most famous one. Of course, the price is more expensive. Generally, it's not cheap to be associated with the specialty.
The most practical function of the bicycle code meter is the total mileage. This shows how many kilometers your bicycle has ridden since the day when the code meter is installed. This can greatly facilitate riders to understand the status of their bicycle. For example, you can know how long it has not oiled the chain, how long it has not maintained the flower drum, etc.
