What Bluetooth bike radars is Cadence compatible with?
Cadence is compatible with several Bluetooth radars, including:
- Garmin Varia (Bluetooth models RCT715/RCT716, RTL515/RTL516, RVR315, etc)
- Bryton Gardia
- Giant Recon+
- Magicshine SEEME
- CYCPLUS L7
- Magene L508
- Lezyne Rear Drive
I’d love to add support for all the new bike radars coming to market, but it’s unfortunately not possible yet. There’s currently no standard Bluetooth profile for radars, each company seems to be doing it differently, so support has to be added manually.
The Trek CarBack, Wahoo Trackr, iGPSPORT SR30, and other radars that are not listed as compatible above only work with their own apps and don’t broadcast radar data over Bluetooth for other smartphone apps to use.
If you’d like these radars to work with smartphone apps, please encourage the manufacturers to add support.
Please see below for the latest updates.
Feb 15, 2026:
The Garmin Varia RearVue 820 is compatible with Cadence but only provides standard radar data: no lane or vehicle size data is currently available. Also, it’s not currently sending car speed/threat levels, so Cadence can’t detect car speed like it does with other radars. Hopefully Garmin adds that data back, but if not, it’ll require an update to Cadence to calculate speed from distances.
