Bryton Smart Cadence & Speed Sensor Compatible with Smartphone

In this review the Bryton Smart Cadence Sensor is presented as a compact, magnetless cadence and speed sensor aimed at cyclists who want a simple wireless way to monitor pedaling performance. The single biggest reason to buy is its dual ANT+/BLE connectivity, which lets riders pair the sensor to both popular bike computers and smartphone training apps without fiddly magnets or excessive setup. It installs quickly on a crank arm and is easy to move between bikes, making it practical for commuters, club riders, and anyone tracking cadence without complicated hardware.

Key Features

• Dual ANT+/BLE: Connects wirelessly to most GPS bike computers and smartphone training apps for flexible data capture during rides.
• Magnetless cadence sensing: Measures pedaling cadence without a magnet on the crank, simplifying installation and reducing setup errors.
• Easy installation: Installs in seconds on the crank arm and includes additional holes for cable ties to fit a wide range of crank sizes.
• Replaceable battery: Uses a CR2032 coin battery that can be swapped without replacing the entire unit, reducing long term cost.
• Moveable between bikes: Lightweight and compact design lets riders transfer the sensor quickly between road, gravel, or commuter bikes.

Who It's For

The Bryton sensor is ideal for cyclists who already use a compatible bike computer or a smartphone training app and want a hassle-free cadence readout. It suits club riders, training cyclists, and everyday commuters who value quick setup and cross-device pairing via ANT+/BLE.

Cyclists who need integrated power measurement, head-unit-only proprietary ecosystems, or sensors with built-in GPS should look elsewhere, since this device focuses on cadence and speed pairing with external systems rather than replacing a full bike computer.
