The SpeedForce from SpeedX fits a cycling computer and headlight inside the handlebar stem, offering a sleek, self-contained package.
Meant to replace the existing bike stem, the SpeedForce communicates with the system’s included pedal and wheel sensors using ANT+ wireless protocol, while its Bluetooth connectivity allows the user to access their smartphone for more functions. Information (such as navigation cues and message alerts) is displayed on the SpeedForce’s 1.6-inch color screen, and collected data is stored on the device’s onboard memory.
