TR70 Smart Radar Rear Light – Compatible with Garmin, Wahoo, Hammerhead, Sigma, Mio, etc.

Ride with more peace of mind on busy roads. The Coospo TR70 is a smart radar rear light that monitors up to 140 meters behind you and alerts you to approaching vehicles via your bike computer or phone. That means less shoulder-checking—while still staying fully aware of what’s coming from behind.

Pros & Cons

Pros

• Very long battery life up to 40 hours thanks to the 1500 mAh battery

• Radar detects traffic up to 140 m behind you with a wide 220° field of view

• 7 light modes, incl. group ride mode and smart warning flashes for approaching traffic

• IP67 water- and dustproof: built for Dutch rain rides and gravel adventures

• Works via the ANT+ radar protocol with Garmin, Wahoo, Bryton, iGPSPORT, and more — and with the CoospoRide app on your phone

• Compact and lightweight: only 64 g and easy to mount on the seatpost

Con

• To receive radar alerts you need a compatible bike computer, sports watch, or smartphone app; without that it “only” functions as a powerful rear light.

Product Description

If you regularly ride on fast country roads, provincial routes, or dark dikes, you know how tense it can feel when a car suddenly appears behind you. The Coospo TR70 Smart Radar gives you literal “eyes in the back of your head.” Its built-in millimeter-wave radar detects vehicles up to 140 meters behind you and sends alerts to your bike computer, sports watch, or the CoospoRide app. You can see and hear what’s happening behind you—before you can even sense it.

With up to 40 hours of battery life, you won’t need to recharge after every ride. Perfect for committed commuters, long weekend rides, and cycling holidays. Charging is easy via USB-C, and the TR70 is fully charged again in about 2 hours.

The TR70 combines radar with a bright rear light of up to 70 lumens, visible from up to 1.5 km (depending on mode and conditions). Choose from 7 light modes, including a dedicated group ride mode that won’t blind riders behind you—while still keeping you highly visible to traffic.

Thanks to its IP67 rating, you don’t have to worry about heavy rain, muddy sections, or winter road salt. Weighing only 64 grams with a compact housing (96 × 39 × 23 mm), it fits neatly under almost any saddle and mounts on both round and aero seatposts (rubber shims included).

The TR70 uses the standard ANT+ Radar protocol, making it compatible with many popular bike computers such as Garmin, Wahoo, Bryton, and iGPSPORT. No bike computer? Use Bluetooth with the CoospoRide app and see approaching vehicles directly on your smartphone screen.

In short: if you want more safety and awareness on the road—without jumping straight to the most expensive top-end options—the Coospo TR70 is a smart upgrade for your road bike, gravel bike, or commuter.
