How do bike computer speedometers work

Bike computer speedometers measure the speed of a bicycle by using a variety of sensors. The most common type of sensor is a magnet that is attached to the spokes of the wheel. As the wheel turns, the magnet passes by a sensor that is mounted on the bike frame. The sensor detects the changes in the magnetic field caused by the passing magnet and uses this information to calculate the speed of the wheel.

Other types of sensors that can be used in bike computer speedometers include:

Hall effect sensors: These sensors detect the presence of a magnetic field and can be used to measure the speed of a wheel without the need for a magnet.
Optical sensors: These sensors use a light beam to measure the speed of a wheel. The light beam is reflected off of the spokes of the wheel and the time it takes for the light to return to the sensor is used to calculate the speed of the wheel.
GPS sensors: These sensors use the Global Positioning System (GPS) to measure the speed of a bicycle. GPS sensors are more accurate than other types of sensors, but they can also be more expensive.

Bike computer speedometers can be used to measure the speed of a bicycle in a variety of units, including miles per hour (mph), kilometers per hour (km/h), and feet per minute (fpm). Some bike computer speedometers also have other features, such as odometers, trip computers, and heart rate monitors.
