Motocross Racer Aidan Zingg Dead at 16 Following Mid-Race Accident
The motocross community is in mourning.
Aidan Zingg, a prodigy in the off-road motorcycle racing world, died following a mid-race accident while competing at the 2025 Mammoth Motocross event in Mammoth Lakes, Calif., June 28, according to multiple outlets. He was 16.
The Washington native "went down in a corner during a race" and was then "run over by multiple bikes and remained unconscious on the track for two laps before the race was red flagged," Dirtbikelover reported. However, the outlet noted that, despite speculation, "he wasn’t involved in a mid-air collision.”
E! News has reached out to local authorities for comment but has yet to hear back.
Aidan's older sister Alexandria Zingg honored her brother with handful of images and videos on social media alongside a heartfelt tribute.
"It’s been a day and I feel like it’s been a lifetime," the 18-year-old wrote on Instagram June 29. "My heart is completely broken. You used to joke that I was so old and that I’d die first, I would always joke that you were crazy and you’d be the first. Now I’m sitting here wishing with everything that I am that you were right so I’d never have to live a day without you."
"I have no idea what today, tomorrow, or the rest of my life looks like without you in it," Alexandria continued. "I had everything planned. God had a different plan. I’ll forever find myself longing for that last hug, that last I love you that I never got. You are a light. The vibrancy to every color in my world."
The horseback rider pledged to "work twice as hard, be twice as good, shine twice as bright" in the wake of her brother's passing.
"I can’t believe you get to meet Jesus before me," she finished. "Even now you’re still kicking my butt. I am so incredibly proud of you. You were so incredible that God only needed you here for 16 years to fulfill your purpose and He just couldn’t wait any longer to bring you home. I could write a thousand more things to you, but I’ll save them for my prayers. I love you so much it’s unreal. Fly high but don’t go too far. I love love love you bud."

Pillars of the motocross community paid tribute to Zingg after the tragedy, with journalist Donn Maeda calling him "one of those kids that made an impression on you from the moment you met him."
"I interviewed him for our race series years ago when he was on a 65," he wrote on Instagram June 29, "and when I asked him how long it’d be until he beat his dad, he smirked and said, 'Soon, I’m sure.'"

"After that, he always went out of his way to say hello," the SwapmotoLive.com founder said, "even recently when he grew into a fast big bike rider…you know; the age when teens get cocky and cool. Not Aidan."
The journalist reflected on the impact Zingg's death will have on those who loved him dearly.

"I’m in Illinois at the Mini Monsters at Lincoln Trail, and I have many memories of him at these races," he shared. "Motocross gives us all so much pleasure, but it can also take from us. I’ve been told that he suffered fatal injuries at Mammoth MX today. My heart goes out to the Zingg family. I can’t even fathom what they’re feeling. Rest easy, buddy."
Industry vet Kris Keefer also took a moment to honor the rising star.
"Heavy day at Mammoth Mountain MX," he wrote on X. "Please put your prayers and thoughts towards the Ziing family. Hug your loved ones and tell them you love them."
