FENNEC R200 Radar Rear Light
Know what is behind you.
FENNEC R200 pairs a rear light with a radar that tracks vehicles approaching from behind. On a compatible cycling computer, such as Garmin, Wahoo, Hammerhead, Coros, Bryton and iGPSPORT, they appear on your screen. Without one, the light sounds its own alert and intensifies its flashing pattern to catch the attention of the approaching driver.
Works with cycling computers that support ANT+ bike radar. No phone app, no Bluetooth.

What is in a FENNEC R200
An alert without a screen
No head unit? The light sounds its own warning.
A rear light that does its job
Up to 100 lumens, with a brake light.
Simple by design
ANT+ connection and USB-C charging. No phone app and no Bluetooth to manage.
How the radar warns you.
The radar tracks vehicles closing in at least 10 km/h faster than you. Drag the car, or tap a distance, and see what changes.

Maker's figures, not yet independently tested. It ignores parked cars, poles and riders going your speed or slower. Riders faster than you will still set it off.

Does FENNEC R200 work with my phone?
No. FENNEC R200 connects over ANT+ and has no Bluetooth or phone app. It shows radar data on cycling computers that support ANT+ bike radar, including Garmin, Wahoo, Hammerhead, Coros, Bryton and iGPSPORT. If you ride without one, the light still sounds its own alert when a vehicle approaches, and it intensifies its flashing pattern to catch the driver's attention.
Do I need a cycling computer?
No. Without one, the light sounds its own alert when a vehicle approaches and intensifies its flashing pattern. A computer that supports ANT+ bike radar adds the vehicles to your screen.
Will it go off on a group ride?
It is built to ignore riders going your speed or slower. A rider coming up faster will still set it off. Our group-ride results will be posted on this page.
How long does the battery last?
With the radar off, from about 8 hours on high steady to up to 100 hours in power-saving mode. Radar-on hours: [FROM THE DATA SHEET].
Will it fit my seat post?
The seat-post bracket in the box takes a Garmin-style quarter-turn mount. To put it under an ARAGO light saddle, add the saddle-rail bracket for $15.
Can I use it in Europe?
This version has flashing modes, which EU rules do not allow on the road. A version certified for Germany is planned for January 2027.
