So What’s The Point of having one?
Take a look at these bicycle computers:
A bike computer uses magnets and sensors in the wheel and frame to track your wheel’s speed. In more complex versions, cadence tracking is available. The feature set of a bike computer is often less than that of a GPS device, but it is significantly less costly to buy one.
Each wheel revolution is recorded by tiny sensors attached to the wheels or forks. Cycle computers in Australia exist in various forms, from simple devices that offer a modest but valuable quantity of data to more complicated ones that are crucial training tools for expert riders. In the last several years, Garmin, Polar, and Wahoo have all increased in popularity as GPS bike computers.
Distance travelled, time spent riding, and speed are easily accessible in even the most basic bicycle computers (trip time). At the next level, you should be able to pick up a wireless sensor that doesn’t need a hefty connection between sensor and computer.
It’s totally up to you what features you want and how much you’re willing to spend on them. Casual and competitive cyclists who wish to keep track of their daily miles may do so with a central computer. When it comes to training, a good computer is necessary (along with a heart rate monitor, of course).
The great majority of cycle computers in Australia use magnetic sensors to collect and transmit data. A small magnet is often attached to a spoke on the front wheel, and a sensor is attached to one of the fork legs in most instances. Using the wheel’s rotational frequency, the computer calculates the distance travelled (depending on its diameter) and its speed. The computer must first be calibrated to match the wheel size of the rider (the instruction manual will explain how to do this).
Putting the magnet in an area where the sensor can see it will allow it to read it. In your computer’s instruction manual, you’ll find thorough instructions on how to set up your computer. A few years ago in Australia, it was common for budget computers to utilise cables to connect to sensors. At the same time, more modern versions used wireless transmissions, making installation more accessible, making the bike seem less crowded, and making it possible to use computers with suspension forks.
On the other hand, wireless computers have become more inexpensive, and many commuters find them worthwhile.
The most significant difference between bicycle computers is the level of functionality. If you have a primary computer, you’ll be able to see how long it’s been since your last ride, how fast you’re going, and how far you’ve gone in total (odometer). A second magnet-and-sensor set mounted to the pedal crank and chainstay records average speed, maximum speed, lap lengths, and other information in addition to monitoring cadence on high-end computers (to count the number of times the pedals are rotated).
For example, suppose a GPS training programme that incorporates features such as navigable maps and the ability to submit training and ride data to specific sites/apps or through social media is what you’re searching for. Another source may be more appropriate in that situation. Many riders are satisfied with a small, light, and inexpensive package with a broad range of functionality. Before acquiring any non-standard components, check the fork and handlebar mounts.
