Navihood B2 Expression Radar Laser Taillight
Rear-view radar. Custom LED display. Laser safety line.
The Navihood B2 combines intelligent radar detection, a high-visibility taillight, and a rear safety laser into one sleek, lightweight unit. Designed for riders who want advanced situational awareness without adding bulk to their bike.
Rear Radar Awareness
The integrated millimeter-wave radar detects vehicles approaching from behind up to 150 meters away, with a 45° horizontal detection angle. It can track up to eight vehicles simultaneously, automatically assessing threat levels and triggering visual alerts.
- Real-time vehicle detection
- Color-coded risk indication
- Brake alert when sudden deceleration is detected
Compatible with Navihood bike computers and most major GPS cycling computers via ANT+. Audio and visual alerts keep you informed without distraction.
High-Visibility Expression Display
A 234-dot dual-color LED matrix (red & yellow) allows you to display custom animations, symbols, or scrolling messages. Personalize your ride through the Navihood App and share designs with other users worldwide.
- Custom animated expressions
- Scrolling text for group ride communication
- Turn-by-turn synchronization with supported Navihood computers
Integrated Laser Safety Line
A rear-facing laser projects a visible boundary line behind your bike to increase rider presence on the road. When a vehicle approaches at a potentially unsafe distance, the laser flashes rapidly to increase visibility.
