How to Connect the CHIGEE SR-1 to Your Phone (and What to Set Up First)

Your SR-1 arrives, you mount it, wire it, and ride off. Ten minutes later you're crawling through city traffic and the indicator keeps lighting up at every stoplight. It's easy to conclude the radar is "too chatty" — but what's really happening is that it's still running factory defaults. Two minutes in the CHIGEE GO app fixes that, and pairing takes less time than putting on your gloves.

This guide walks through the phone connection step by step, then gives a quick tour of the radar settings you'll find once you're in.

What you need before you start

• An SR-1 that's installed and powered on (it connects over Bluetooth 5.0, so your phone just needs Bluetooth enabled)
• The CHIGEE GO app, downloaded from the App Store or Google Play
• Your motorcycle parked — do the first setup standing still, not mid-ride

Connecting the SR-1: five taps

1. Open the CHIGEE GO app and tap My Devices.
2. Tap Add Device.
3. Select Bluetooth Accessory: SR-1.
4. Tap Connect.
5. Wait for the confirmation — once you see Connection successful, you're in.

That's the whole pairing process. From here, the app becomes your control panel: day-to-day radar settings and firmware updates all live in one place.

A quick tour of the radar settings

You don't need to touch most of these more than once. But each one exists because of a real riding situation, so it's worth knowing what they do before your next ride.

Radar on/off. In Settings, you can enable or disable the radar entirely — useful if you're loading the bike on a trailer or working near it in the garage and don't want alerts.

Left/Right Mirroring. If the indicator lights up on the opposite side of the approaching vehicle — say, a car closes in on your left but the right light comes on — turn this on to flip the sides. If your radar is installed correctly, this setting stays off; it's off by default.

Rear warning light. The SR-1's tail-facing light can be switched on or off depending on how you want the radar to communicate with traffic behind you.

Collision Warning. CHIGEE recommends keeping this on — it helps improve riding awareness when a vehicle closes in fast from behind. The radar never brakes or steers for you; it makes sure you look at the right moment. For how the alert layers work with and without a display, see how the SR-1 and a CHIGEE display build layered awareness.

Sensitivity. How early the radar flags what's behind you. Tune it to how you actually ride — a weekend canyon rider and a daily commuter in dense traffic will land on different settings, and both are right.

Activation Speed. This sets the speed below which the radar stays quiet. You pick from preset speed steps in the app, and the official recommendation is 10 km/h — it keeps the radar from firing off alerts while you're parked, filtering through a lot, or inching forward at a light. If your first rides felt noisy, this is usually the setting to check first.

Firmware updates live here too

Once connected, the app also handles firmware upgrades for the SR-1. Checking for an update right after your first pairing is a good habit — improvements to detection behavior ship this way, no cables or shop visits needed.

FAQ

Do I need a CHIGEE display to use the app with the SR-1?

No. The SR-1 pairs directly with your phone over Bluetooth through the CHIGEE GO app, which is where these settings and firmware updates are managed.

Why does the indicator light show the wrong side?

That's what Left/Right Mirroring is for — turn it on to flip the indicator sides. If the radar is installed correctly, you shouldn't need it.

What should I set the Activation Speed to?

CHIGEE's official recommendation is 10 km/h. It prevents frequent alerts at low speed or while parked.

How do I update the SR-1 firmware?

Connect through the CHIGEE GO app first; firmware upgrades are done from the app once the radar is paired.
