8 other reviews for this part

The reviewer tests and discusses a radar rear light from Magene (referred to as 'Mine' or 'Mene' throughout the transcript). They state it is a slim, lightweight, and good-looking light that does not appear or feel cheap. The radar has a 140m range, which often detects cars well before the rider can hear them, making it an effective early warning system. It uses ANT+ for compatibility with most bike computers and was tested flawlessly with Hammerhead Karu and Wahoo Roam devices. It features a USB-C charging port, a Garmin-style quarter-turn mount, and seven light modes, including a braking mode that increases brightness and flash rate when slowing down. The reviewer found it to be very accurate with no false positives or negatives, performing as well as a Garmin Varia in their experience. They conclude it offers excellent quality and performance for half the price of a Garmin.

  • Good-looking and doesn't look or feel cheap
  • 140m radar range (same as Garmin Varia)
  • Often detects cars before the rider can hear them
  • Works as an effective early warning system
  • Uses ANT+ for broad bike computer compatibility
  • Works flawlessly with Hammerhead Karu and Wahoo Roam

Cons

  • Battery runtime could be better
