Headlights and Tail Lights | Threshold Cycling

High-Performance Bike Lights, Smart Headlights & Garmin Varia Radar

Maximize your riding safety, daytime visibility, and nocturnal road awareness with professional cycling lights and vehicle radar systems from Threshold Cycling. Whether you are navigating fast dawn pacelines, descending unlit mountain canyons, or commuting through heavy urban traffic, modern cycling illumination requires more than raw lumens—it demands precision optical beam control, intelligent braking alerts, and active rear vehicle detection.

As an Official US Authorized Retailer for Garmin and Ravemen, we curate the cycling industry's most dependable illumination and safety hardware. Every system is engineered to solve specific cockpit and safety challenges:

  • Active Rearview Radar (Garmin Varia RTL515): Acts as a digital rearview mirror, utilizing built-in radar to track motor vehicles approaching from up to 140 meters (153 yards) behind you while alerting you via visual and audible cues on your cycling computer.
  • Automotive-Grade Anti-Glare Optics (Ravemen PR & CR Series): DuaLens and T-shaped optical cutoffs cast a broad, even carpet of light across the road surface while blocking upward scatter to prevent dazzling oncoming drivers, cyclists, and pedestrians.
  • Seamless Cockpit Integration (Ravemen FR Series): Ultra-compact daytime safety flashers engineered to sandwich flush between your GPS bike computer and out-front mount, keeping your handlebars 100% clean and aerodynamic.
  • Smart Deceleration Detection (Ravemen CL06 & TR500): Precision 3-axis internal accelerometers detect braking and instantly surge to maximum solid output, warning trailing traffic the moment you slow down.

Frequently Asked Questions

How does the Garmin Varia RTL515 Rearview Radar work, and which cycling computers does it pair with?

The Garmin Varia RTL515 is an active rearview radar and daylight safety tail light that acts as a digital rearview mirror for road and gravel cyclists:

  • 140-Meter Vehicle Detection: Built-in radar tracks approaching motor vehicles from up to 140 meters (153 yards) behind you, calculating both distance and closing speed.
  • Universal Head Unit Compatibility: Using dual ANT+ and Bluetooth BLE protocols, the Varia RTL515 pairs with Garmin Edge computers, Wahoo ELEMNT units, Hammerhead Karoo, Stages, and smartphones running the Garmin Varia app or compatible third-party apps.
  • Visual & Audio Alerts: Your head unit displays color-coded side columns (amber for approaching vehicle, red for high-speed approach, green for all clear) accompanied by audible warning chimes.
  • Daylight Visibility: The tail light is visible from up to 1 mile away in bright direct sunlight with 220° side visibility, offering up to 16 hours of battery life in Day Flash mode and an 8-hour Peloton mode that avoids dazzling pack riders.

What is anti-glare StVZO beam technology on Ravemen headlights, and why is it essential for road cyclists?

Traditional cycling headlights emit a round, cone-shaped beam that scatters light high into the eyes of oncoming motorists, cyclists, and pedestrians, causing blinding glare and hazardous conditions. Ravemen headlights solve this with automotive-grade optical engineering:

  • DuaLens & T-Shaped Optical Cutoff: Ravemen uses a precise horizontal cutoff line (modeled after strict German StVZO road safety regulations) that concentrates lumens downward and outward across the road surface while blocking upward light bleed.
  • Safer Riding in Traffic: You get superior illumination of asphalt cracks, potholes, and debris directly in your riding path without blinding oncoming traffic or endangering fellow group riders.
  • Dual-Beam Versatility (PR Series): For unpaved roads and technical singletrack, models like the PR1400 feature a secondary high beam that can be engaged via the wired thumb remote for maximum 1400-lumen trail illumination.

What is the difference between the Ravemen PR Series, CR Series, and FR Series headlights?

Ravemen designs specific headlight series tailored to different riding conditions and cockpit setups:

  • PR Series (e.g. PR1400): High-power dual-lens headlights designed for demanding road, gravel, and trail night rides. Features up to 1400 lumens, wired handlebar thumb remote for instant high-beam toggling, an LED runtime screen, and a USB power bank output to charge your GPS or phone on the go.
  • CR Series (e.g. CR1000, CR600, CR450): Streamlined, lightweight road and commuter headlights featuring T-shaped anti-glare cutoff beams, aluminum casing, wide side visibility windows, and USB-C rechargeable batteries with external power bank pass-through support.
  • FR Series (e.g. FR300, FR160): Ultra-compact daytime safety flashers engineered to sandwich directly between your out-front computer mount and your Garmin or Wahoo cycling computer. Keeps handlebars completely uncluttered while delivering high-intensity daylight warning flashes.

How does the smart auto-brake sensor work on Ravemen tail lights (CL06 & TR500)?

Ravemen smart tail lights incorporate precision 3-axis internal accelerometers to provide automated safety signaling without requiring any cables or manual input:

  • Instant Deceleration Detection: When you squeeze your brakes or slow down rapidly, the sensor instantly detects the momentum change and triggers a 2-second high-output solid burst (up to 500 lumens on the TR500) to immediately alert following drivers and cyclists.
  • Auto Sleep / Wake: When your bicycle is stationary for two minutes, the light automatically enters a low-power standby mode to preserve battery life, and instantly wakes up the moment you start rolling again.
  • Ambient Light Sensor (CL06): Automatically adjusts flashing brightness based on ambient light levels to ensure optimal visibility in bright daylight or dark tunnels.
