Why Choose iGPSPORT SR mini

This is the gold standard in rear-end safety technology: intelligent radar detection that actually alerts you to threats before you can see them. The dual system—radar detection + high-visibility light—creates comprehensive protection. The integration with your bike computer means all information flows through one screen, eliminating the need for multiple devices or complicated setup.

At just 50g, the weight penalty is virtually nonexistent. The 160-meter detection range gives you precious seconds to react to approaching traffic. The intelligent turn detection with 45° angle coverage solves one of cycling's most dangerous scenarios—approaching traffic around blind curves.

This isn't just a light or a radar—it's an intelligent rear-end security system.

How It Works

Real-Time Threat Detection:
The radar constantly scans behind your bike within 160 meters. When vehicles approach, the system analyzes their speed and predicted trajectory. Vehicles that could collide with you within 3 seconds trigger high-risk alerts.

Visual & Audio Alerts:
Threat data displays on your bike computer screen with orange (medium risk) or red (high risk) indicators. Audio alerts accompany all alerts, so you receive information across multiple senses.

Automatic Brake Light:
When you decelerate, the taillight instantly flashes at maximum brightness—warning trailing vehicles and teammates of your changed speed.

Automatic Light Management:
In daylight, switch to radar-only mode and disable the light to save battery. The system automatically activates the light when ambient light drops (entering a tunnel, evening ride).

Radar Detection Explained

How Radar Identifies Threats:
The SR mini uses advanced radar to detect vehicle speed and distance. A truck approaching at 60 km/h from 200 meters away is a lower threat (time to collision is longer). The same truck at 100 meters is a higher threat. At 3 seconds collision distance, it becomes a high-risk alert.

Why 160 Meters?
At typical highway speeds (100 km/h), 160 meters provides roughly 5+ seconds warning before a potential collision—enough time to move position or take evasive action.
