What to Compare Before Buying
- Bike computer: Check that your exact computer model supports the TR70’s ANT+ connection. The description names COOSPO, Garmin, Wahoo, Bryton, iGPSPORT and Magene, but does not identify compatible models.
- Seatpost shape: Check whether your seatpost is round, D-shaped or aero, the shapes listed for the mount.
- Runtime: Treat 40 hours as the stated maximum, and consider whether the available lighting modes suit your intended use.
Compatibility, Size and Fit
The radar can connect to a compatible bike computer over ANT+. Bluetooth connection is described for the CoospoRide app, including setup, firmware updates and customisation. The mount is specified for three seatpost shapes; the broader claim that it fits 99% of bikes is not used here. Confirm fit for your bike and the compatibility of your particular computer before choosing.
Important Limitations
The stated detection distance is up to 140 m, not a guarantee of detection in every situation. The light is described as flashing when vehicles approach and activating a high-beam alert when sudden braking is detected. Its stated 220° visibility and IP67 rating are product specifications, not a substitute for checking whether the light meets your needs and use conditions.
Before You Decide
Confirm your seatpost shape, ANT+ computer compatibility if needed, and preferred connection method. Also consider the seven available modes and the stated maximum runtime when deciding whether this configuration suits your requirements.
