SR-1 Millimeter-wave Radar System
SR-1 Millimeter-wave Radar System
Look Ahead, Radar Protects Your Safety
The SR-1 is an automotive-grade 77GHz millimeter-wave radar specifically designed for motorcycles, featuring 4 proactive early warning modes. It can detect objects up to 70 meters away. Whether it's a rainy day, foggy conditions, or a dark environment, it continuously monitors your rear, allowing you to ride with peace of mind, focus on the road ahead, and increase your confidence while riding.
Developed on real roads, not just in a lab.
The SR-1 millimeter-wave radar system began with a test ride project in 2025 with a simple goal: to create a radar system truly suitable for motorcycles.
For us, it was never just about detection, but more importantly, the system's performance in real-world riding conditions — whether alerts were issued at the right time, clear and easy to understand without being distracting, and whether riders could continuously rely on the system every kilometer.
For this reason, from 2025 to April 2026, Qiji's R&D and testing team repeatedly tested the SR-1 on real roads, including riding motorcycles in various regions around the world. The experience from these rides helped us continuously refine the alert logic, making early warnings more natural, balanced, and consistent with real traffic situations. With OTA update support, SR-1 can continue to evolve.
At the same time, the light bar assembly and radar module underwent multiple redesigns, making them more compact, refined, and suitable for motorcycle installation.
SR-1 is therefore the result of this process — born from real-world riding, repeatedly tested and refined, to provide riders with a more natural form of radar perception.
SR-1 Radar Buying Guide: Motorcycle Compatibility and Alerting
The SR-1 millimeter-wave radar system enhances a rider's rearward situational awareness by detecting approaching vehicles from behind and providing clear visual alerts.
This guide introduces the SR-1's operating principles, compatible motorcycles, components included in the standard kit, compatible CHIGEE displays, and important considerations before installation.
Things to Know Before Buying
The SR-1 can be used in two modes:
-
Independent Mode: Use the SR-1 with the external indicator lights included in the kit. No CHIGEE display is required.
-
Display Integrated Mode: Connect the SR-1 to a compatible CHIGEE display to show radar graphics on the screen, receive audio alerts, and access radar settings.
Motorcycle Compatibility
The SR-1 is designed to be compatible with most motorcycles utilizing a standard 12V electrical system.
It can be installed on a wide range of motorcycle types, including:
-
Off-road bikes
-
Sportbikes
-
Cruisers
-
Touring bikes
-
Naked bikes
