Incident Details
  • Incident Description: I have been riding Ninebot One E+ to work everyday on it, also as a main mode of transportation, for the past 3.5 years in the San Francisco Bay Area, and even take it to nearby beaches such as Half Moon Bay, Monterey or Big Sur when it's sunny here in Northern California. Within a few minutes after the device started making a few popping noise when the power was off, it suddenly exploded and burnt in a vicious fire. I was extremely lucky and no one was hurt. This could have been much, much worse. I could have lost my right leg, I could have died or the entire apartment could have burnt down causing even more casualties. .This is when I realized the sound--and potentially the smell too--was coming from my beloved 3 year long friend. My instinct now as sharp as blade, I knew I needed to do so something. ~11:45AM - I started hearing popping noise. Initially believed to be coming from outside, only to discover nothing outside the front door. ~11:50AM - Noticed repetitiveness in the noise, occurring every 30 seconds to a minute. ~11:55AM - Started smelling something acrid. Starting to be concerned. ~12:00PM - Found the source of the sound (and potentially the smell) 12:01PM - (film shot, of the device making noise) ~12:02PM - Being super safe, I went to the power strip and turned it off ~12:02PM - Then unplugged the cord from the power strip, ~12:03PM - Then unplugged the cord from the unit. ~12:03PM - I raised the handle bar and tried to grab it from the end of the handle bar as usual, but I didn't. Instead, I grabbed the center of the handle and supported with my left hand under the foot pedal so I don't accidentally agitate the unit too much and trigger it to explode. (VERY RISKY) ~12:03PM - I took it outside and leaned it against the immediate exterior wall I was able to get access to. ~12:09PM - I heard a loud explosion with a small fire when I turned. Immediately, one or two more louder and bigger explosions occurred and followed by much bigger fire, creating fizzing sound and burning everything the battery was wrapped in violently. This lasted for a minute. 12:10PM - When the fire was weakening, the property manager luckily was outside and who saw this happening ran towards me to aid and grabbed the fire extinguisher. I knew I had to document this. (photo available)
