How Does a Wireless Bicycle Speedometer Work?
Similar to Wi-Fi computer technology, wireless bicycle speedometers collect and transmit data from different sensors to the main bicycle unit. Wireless bicycle speedometers offer more than current traveling speed to cyclists, reports online cycling publication Bike Cycling Reviews.

Wireless Speed Sensors
-
Inexpensive wireless speedometers utilize a magnet attached to a bicycle wheel spoke. As this magnet passes a wireless sensor it transmits the current speed traveled to the main unit. This unit typically offers current and max speed as well as collecting odometer readings. Most inexpensive bicycle speedometers include 12- or 24-hour clock settings as well. Wireless bicycle speedometers generally require setup processes to input wheel and tire sizes. Without proper wheel and tire data, cyclists cannot record accurate speed and distance readings with the wireless bicycle speedometer.
Wireless Cadence Sensors
-
Mid-level wireless bicycle speedometers utilize additional magnets and wireless sensors to record cadence for cyclists as well. Cadence refers to the revolutions per minute rate at which cyclists spin pedals. Learning proper cadence results in greater distance traveled using less energy, an important lesson for amateur racers and cycling enthusiasts alike. Most cyclists spin comfortably between 60 to 80 rpm; therefore, a cyclist's cadence likely falls between 60 and 80. Wireless cadence bicycle speedometers help train cyclists to use the proper cadence, according to online independent cycling review site Wireless Bicycle Computers.

Wireless Heart Rate Sensors
-
High dollar wireless bicycle computers often utilize wireless heart rate monitors in addition to wireless speed and cadence sensors. Cyclists typically wear a plastic and nylon strap around the chest with battery powered heart sensors built in. The heart rate strap transmits a wireless signal to the main unit and displays information for the cyclist to utilize. Whether attempting to reach peak performance output during standing sprints or ensuring heart rate does not rise too high when exercising after a heart bypass surgery, many cyclists find heart rate monitors of drastic importance during cycling.
