10 reasons to buy

  • Reviewers say the Zecto Drive Alert is a good value, compared to other accelerometer-driven lights.
  • This light turns solid during deceleration and provides a standout flash pattern while stopped.
  • Users and testers note the Zecto’s band stretches easily around larger, round seatposts.
  • Owners like that this Zecto can be attached to a bag, using the included clip.
  • During the night, ‘Flash 1’ mode is “clearly visible” from 350m.
  • ‘Daytime’ flash mode puts out 80 lumens. A tester says it’s visible from 350m.
  • The Zecto Drive Alert has 5 modes: 3 flashing and 2 steady.

7 reasons not to buy

  • A number of owners were not impressed by this light’s battery life.
  • Sometimes, ‘stop’ mode activates when riders are only slowing down.
  • Nighttime flash modes are only 20 lumens, or 5 lumens in ‘Economy’ mode.
  • A tester finds this light’s USB cover to be fiddly.
  • An expert says the Zecto Drive Alert doesn’t fit well around aero seatposts.
  • One tester says ‘Flash 2’ mode isn’t amply visible for nighttime riding.
  • A few owners found that their Zecto Alert failed to charge after a few rides.

Bottom line

Using accelerometers, the Zecto Drive Alert changes modes and increases brightness upon slowing, to act as a brake light. Reviewers say they don’t know how drivers interpret this light’s alert sequences, but do agree that they act effectively as attention-grabbers. At times, the light ‘brakes’ when owners are simply slowing down. In ‘Daytime’ mode, the 80-lumen glow gives great visibility. Some users express concerns over battery life. In response, Lezyne have recently modified the design to increase it by 30%.

Lezyne Zecto Alert Drive Rear

When you stop it switches to a flash sequence which is more noticeable than the 80-lumen Daytime setting. It comes at an extra cost over the standard Zecto Drive, and I’d say it’s worth it. It doesn’t work with aero designs.
