CHIGEE SR-1 Radar System

Ride with more confidence, knowing what's happening behind you. The CHIGEE SR-1 brings the advanced driver-assistance systems (ADAS) you know from premium cars to your motorcycle.

Unlike car systems that are retrofitted, the SR-1 has been developed from the ground up specifically for motorcycles. The SR-1 activates as soon as you ride faster than 10 km/h and continuously monitors the traffic around the rear of your motorcycle.

77GHz — more accurate than the standard
The SR-1 uses 77GHz high-frequency radar instead of the common 24GHz systems, providing millimeter accuracy in measuring distance and relative speed. The higher frequency also reduces interference from signs, lampposts, and other electronic signals along the road.

Four intelligent warning systems

• Blind Spot Detection (BSD) — Monitors blind spots on both sides of the motorcycle, ensuring you never miss a vehicle in your blind spot.
• Lane Change Assist (LCA) — Calculates the speed of approaching vehicles and warns the rider if a lane change is unsafe.
• Rear Collision Warning (RCW) — Tracks the time to collision and provides a warning at a one-second threshold.
• Active Overtake Assist — Warns riders if they return to the lane too early after overtaking.

Active safety system
Most blind spot systems only warn the rider. The SR-1 goes a step further: a built-in bright strobe light is integrated directly into the radar module. When a vehicle approaches dangerously fast from behind, the light automatically flashes — prompting the approaching driver to slow down before a collision threatens. This makes the SR-1 not just a passive sensor, but an active safety device.

Weatherproof & compact
The SR-1 comes in a compact housing of approximately 42mm and meets IP68/IP69 standards, making the system resistant to heavy rain, dense fog, dust, and total darkness.

Connect with your CHIGEE display
When paired with the CHIGEE AIO-5 or AIO-6 smart display, radar data is shown in real-time on the screen. The SR-1 can also be used independently without a display — the included warning lights provide core functionality on their own.
