Bike Seatpost Taillight Bracket – Radar Taillight Mount

Mount Your Taillight. Ride Safer Every Time.

A missing or unstable taillight mount is a safety risk you shouldn't ignore. This bike seatpost taillight bracket is precision-designed to hold your radar taillight securely in place — shockproof, slip-resistant, and built to last ride after ride.

Compact, lightweight, and compatible with the most popular round seatpost sizes. No wobble. No compromise.

Why This Taillight Bracket Stands Out

• Durable ABS Construction — Impact-resistant ABS material delivers long service life even under daily riding conditions and varied weather.
• Shockproof & Anti-Slip Design — Stable, vibration-dampening fit keeps your taillight locked in position on rough roads, cobblestones, and trail descents.
• Wide Seatpost Compatibility — Includes multiple gaskets to fit round seatpost diameters of 27.2mm, 30.8mm, and 31.6mm.
• Dual Mounting Orientation — Base buckle supports both vertical and horizontal taillight mounting to suit your setup preference.
• Universal Radar Taillight Fit — Compatible with a wide range of popular radar taillight models including RVR315, RTL500, RTL510, RTL515, TL300, and iGPS SR30.
• Ultralight & Compact — Weighing virtually nothing at approx. 47.3 × 44.6 × 39.6mm, it adds zero bulk to your setup.

Built for Every Cyclist Who Rides with a Light

Road Cyclists & Commuters

Keep your radar taillight bracket locked and level on your seatpost so your light stays visible and your radar stays accurate at speed.

Night Riders & All-Weather Cyclists

Shockproof construction means your taillight won't vibrate loose or shift position mid-ride when you need it most.

Multi-Bike Setups

The included gasket variety makes it easy to swap between different bikes with different seatpost diameters — one bracket, multiple rides.
