The primary differences between the Garmin Speed Sensor 1 and Speed Sensor 2 lie in their connectivity options and design for installation, with Speed Sensor 2 being an updated, more versatile version.
The Speed Sensor 2 offers enhanced features such as dual connectivity and a streamlined, magnet-free design, simplifying setup and improving compatibility.
Key Differences: Garmin Speed Sensor 1 vs. 2
To provide a clear comparison, here's a table outlining the distinct features of each model:
| Feature | Garmin Speed Sensor 1 (Original) | Garmin Speed Sensor 2 (Updated) |
|---|---|---|
| Connectivity | Primarily relied on ANT+ wireless protocol. | Features ANT+ and adds Bluetooth Low Energy (BLE) connectivity. |
| Design | Often required a separate magnet attached to the wheel spoke. | Magnet-free single unit that attaches directly to the wheel hub. |
| Installation | Required careful alignment between the sensor and the wheel magnet. | Simple installation; just hooks onto the wheel hub. |
| User Experience | More involved setup with magnet alignment. | Easier, quicker, and more flexible setup. |
Detailed Enhancements of Speed Sensor 2
Garmin's Speed Sensor 2 represents a significant evolution from its predecessor, focusing on user convenience and broader compatibility.
Connectivity Enhancements
One of the most notable upgrades in the Speed Sensor 2 is its dual-band connectivity. While the original Speed Sensor 1 was primarily limited to ANT+ for communicating with Garmin devices, the Speed Sensor 2 adds Bluetooth Smart (BLE). This addition drastically expands its compatibility, allowing it to connect seamlessly with a wider range of devices, including:
- Garmin GPS cycling computers (e.g., Edge series)
- Smartphones running cycling apps (e.g., Zwift, Strava)
- Third-party bike computers
- Fitness watches that support Bluetooth sensors
This dual-protocol support makes it easier to use the sensor across various platforms without being restricted to ANT+-only ecosystems.
Simplified Design and Installation
The design of the Speed Sensor 2 is a testament to user-friendly engineering. Unlike the original, which typically required a separate magnet to be attached to a wheel spoke and precise alignment with the sensor unit mounted on the fork, the Speed Sensor 2 is a single, integrated unit.
- Magnet-Free Operation: It directly attaches to the wheel hub, eliminating the need for any magnets. This not only cleans up the bike's aesthetic but also removes a potential point of failure or misalignment.
- Effortless Attachment: Installation is incredibly straightforward. Users simply hook the compact unit onto the wheel hub, and it's ready to go. This "just hook it on and go" approach makes it ideal for quick setup, whether you're swapping wheels or moving the sensor between bikes.
Overall User Experience
These design and connectivity improvements culminate in a significantly enhanced user experience for the Speed Sensor 2. The hassle of magnet alignment is gone, and the broadened compatibility means cyclists can more easily integrate speed data into their preferred training apps and devices. This makes the Speed Sensor 2 a more versatile and convenient tool for accurately tracking cycling speed and distance, whether for outdoor rides or indoor training.
