Cosari VeloPulse Pro

Features

It Reads Your Braking, Not the Road

A filtered 6-axis accelerometer tracks forward deceleration and ignores vertical vibration from chipseal and potholes. When you actually slow down, it surges to 120 lumens of solid red for three seconds.

It Fits the Bike You Already Have

Clamp it under standard 7mm saddle rails for a clean, tucked look, or strap it to a round or D-shaped aero seatpost. Both mounts use the same quarter-turn lock, so the light moves between them in seconds.

It Keeps Water Out for Good

Unscrew the knurled tail cap to reach the USB-C port and battery gauge. A silicone O-ring seals the threads, so rear-wheel spray has no gap to work through.

• 220° Wide-Angle Visibility

  The faceted optical dome spreads light 220 degrees, so cross traffic at side streets and roundabouts sees you too, not just the car directly behind.

• 45 Hours Between Charges

  A 500mAh cell runs up to 45 hours in eco-pulse mode, and the 4-LED gauge removes the guesswork before long rides.

• Paceline-Friendly Modes

  Switch to the gentle breathing pulse on group rides and save the full strobe for solo miles on busy roads.

• Active Brake Boost

  Touch your levers and the lens jumps to a solid 120-lumen red for three seconds, so drivers know you're slowing before they close the gap.

• Auto Sleep & Wake

  Roll the bike and it turns on. Park it and it sleeps 120 seconds later. You'll forget where the power button is.

• Sealed Aluminum Body

  Machined 6061 aluminum with an IPX6 threaded O-ring seal over the USB-C port. No rubber flap for tire spray to get past.

How to use it

1. 1

   Clip the Mount On

   Clamp the bracket under your saddle rails, or wrap the silicone strap around your seatpost. It takes about 30 seconds.

2. 2

   Quarter-Turn to Lock

   Push the light into the mount and twist 90 degrees until it clicks flush. No wobble, no droop.

3. 3

   Roll Out and Ride

   Move the bike and the light wakes up on its own. Brake and it flares red. Park it and it goes back to sleep.
