Description

Okay, this one is a little different than my usual videos, but definitely don't miss it! A Chinese cyclist encountered a problem with his Magene QED brakes that led to a crash on the downhill. Unfortunately, he ended up in the hospital. But what actually happened? I spoke to Mel, who explained everything in detail and told me the whole story. Sit back and get some popcorn, because this is worth it.

Magene QED Groupset

Created: March 29, 2026
3 other reviews for this part

The reviewer discusses a serious safety incident involving the Magene QED groupset where a cyclist crashed due to complete brake failure. The analysis reveals a design flaw in the QED brake system where, unlike Shimano, SRAM, or LTwo systems, the calipers fail to maintain contact with the rotor when brake pads are worn down, creating a dangerous gap that eliminates braking power. Magene initially blamed the user for improper installation and component choices, but independent mechanic testing confirmed the system's inherent flaw.

AI-Summary

Pros

  • Magene QED groupset is only sold through authorized channels in China, which the reviewer praises as controlled distribution
  • Magene responded quickly to the incident by sending technicians to inspect the bike and provided a wheelchair as a gesture

Cons

  • Critical design flaw in QED brake system where calipers fail to maintain contact with rotor when pads are worn down
  • Complete brake failure in both front and rear brakes led to a serious crash requiring surgery
  • Magene's initial response blamed the user rather than acknowledging the product flaw
  • The brake reservoir is insufficiently sized to allow pad contact at extreme wear limits
  • Magene has a history of high failure rates with some electronic components according to the reviewer
  • Poor after-sales attitude and culture from Magene based on reviewer's experience
  • The product was released without adequate extreme condition testing
