Navihood Rear Radar and Laser Light

Description

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.

Long Battery Life

Powered by a 1500mAh battery and optimized low-consumption LED + radar system, the B2 delivers up to 17 hours of runtime with radar, laser, and expression display active.
