A speedometer in bikes is a device used to measure and display the speed at which the bike is moving. It can be either mechanical or digital, and it is commonly found in motorcycles, bicycles, and electric bikes.

Here are the key components and types:

1. Mechanical Speedometer:

• Function: Works with a cable connected to the wheel hub or gearbox, which rotates as the wheel spins. This mechanical action is converted into a speed reading.
• How it Works:
  • The spinning wheel drives a flexible cable that turns gears inside the speedometer.
  • The rotation of the gears is proportional to the bike’s speed, which is displayed on a dial.

2. Digital Speedometer:

• Function: Uses electronic sensors, often magnetic or GPS-based, to detect the speed of the bike and display it on a digital screen.
• How it Works:
  • A sensor is placed near the wheel, detecting how fast it rotates.
  • This information is processed electronically and shown on an LCD or LED display.
  • Some modern digital speedometers use GPS to track speed without the need for physical sensors on the wheels.

3. Key Features:

• Odometer: Measures total distance traveled.
• Trip Meter: Records distance for individual trips.
• Average Speed: Some digital models calculate average speed.
• Max Speed: Certain models store the maximum speed reached.
• Backlight: Digital speedometers often have illuminated displays for night riding.

4. Installation & Calibration:

• Mechanical speedometers are more complex to install due to their reliance on physical connections to the wheel or gearbox.
• Digital speedometers are easier to install, often requiring a sensor on the wheel and a small screen mounted on the handlebars. Calibration may be needed to ensure accurate speed measurement based on wheel size.
