Ravemen NT201 Bike Radar Tail Light — 80 Lumen Wide-Angle Rear Light with ANT+ Radar and Dynamic Brake

The Ravemen NT201 is a compact rear bike light with built‑in ANT+ radar that warns you of approaching vehicles up to 140 m away while delivering an 80‑lumen wide‑angle beam for strong daytime and nighttime visibility.

Designed for commuters and performance cyclists who want extra awareness without juggling apps, the NT201 pairs directly with compatible bike computers to relay visual and audible alerts. It also operates independently as a high‑visibility tail light with multiple modes, a dynamic brake lamp and smart motion sensing for practical day‑to‑day use.

How does the radar improve rear detection on busy roads?

The NT201’s radar continuously scans behind you and reports approaching vehicle distance and relative speed to ANT+‑enabled head units. This creates an earlier, objective cue that a vehicle is closing, helping you anticipate interactions in traffic.

• Effective detection range: up to 140 meters for vehicles traveling 10–160 km/h
• ANT+ pairing: integrates with supporting cycling computers for visual and audio alerts
• No smartphone app required: radar data delivered through compatible on‑bike displays

What visibility and lighting modes does the NT201 offer?

The light produces 80 lumens from a wide‑angle output designed to increase your conspicuity up to about 1.6 km in optimal conditions. Multiple modes let you balance brightness and runtime for daily commuting, group rides or long outings.

• Six modes: high, low, slow flash, warning flash, daytime warning, and pulse
• Longest runtime: up to 23 hours on slow flashing; brightest warning mode runs up to 16 hours
• Wide viewing angle to improve side and rear detection by other road users

How do the dynamic brake and motion sensors enhance safety?

The NT201 has a built‑in motion sensor that detects deceleration and instantly shifts to a brighter brake light, signaling following traffic more clearly. The same motion circuitry manages automatic sleep/wake to conserve battery and simplify use.

• Dynamic brake activation: automatically brightens when you slow down
• Auto sleep/wake: preserves charge when parked and wakes on movement
• Simplifies operation—fewer button presses during rides

What mounting and weather protection does it provide?

The NT201 includes a versatile mount designed for round and aero seat posts up to 45 mm wide and can also fit saddle rails with the appropriate adapter. Its IPX6 rating means the unit withstands heavy rain when the charging cover is securely closed.

• Mounting: compatible with round and aero seat posts up to 4.5 cm wide; saddle rail adaptable
• Durability: IPX6 water resistance for reliable performance in wet conditions
• Secure fastening design keeps the light stable on rough roads

Who is this for: The Ravemen NT201 suits riders who want a compact, standalone rear light that increases visibility and gives objective rear‑approach alerts via ANT+ integration. It’s ideal for daily commuters, club riders, and anyone using an ANT+‑capable bike computer who prefers simple, on‑device radar alerts without an extra smartphone app. Riders who need a weatherproof, long‑runtime tail light with dynamic braking signalling will find the NT201 a practical upgrade.
