Intelligent Lighting for Safer, Smarter Night Rides

A professional bike light should do more than just get bright.

The Enfitnix Navi800 Ultra Smart Bicycle Front Light combines powerful illumination, intelligent brightness control, dual-beam functionality, and a rider-focused design to deliver a safer and more comfortable cycling experience — from daily commuting to demanding night rides.

800 Lumens with Dual Beam Control

Featuring a powerful 800-lumen output, the Navi800 Ultra provides excellent visibility in dark environments.

Its high beam and low beam modes allow riders to adapt quickly to different riding conditions:

• High Beam Mode — provides extended visibility for open roads, trails, and low-light environments.
• Low Beam Mode — creates a controlled light pattern for urban riding while reducing glare toward oncoming traffic.

Whether you are riding through city streets or exploring unlit roads, the Navi800 Ultra gives you the right amount of light exactly when you need it.

Smart Adaptive Brightness with Light Sensor Control

The built-in ambient light sensor automatically detects surrounding brightness and adjusts the light output accordingly.

During daytime or well-lit areas, the light reduces brightness to save battery. When entering darker environments, it automatically increases output for better visibility.

Smart lighting means you can focus on riding — not adjusting your light.

Safety-Focused Design for Every Ride

Every detail of the Navi800 Ultra is designed with real-world cycling in mind.

A dedicated security tether hole allows riders to attach a safety strap, providing extra protection against accidental drops or unexpected mount failure.

Small detail. Big peace of mind.

Replaceable Battery System

Unlike traditional bike lights with built-in batteries, the Navi800 Ultra features a replaceable rechargeable battery design.

Benefits include:

✓ Extend the product lifespan
✓ Carry spare batteries for longer rides
✓ Replace the battery instead of replacing the entire light

Designed for cyclists who ride more and upgrade less.

Premium Aluminum Construction

Built with a durable aluminum alloy body, the Navi800 Ultra offers excellent heat dissipation while maintaining a compact and lightweight profile.

Its rugged construction and weather-resistant design make it reliable for commuting, road cycling, gravel riding, and outdoor adventures.
