It mentions two supposed faults: use of a quick release mechanism on the front wheel in conjunction with disc brakes; that the 'electrical power failed to shut down'. There's potentially merit in the first one, but it seems like the front wheel didn't actually loosen or eject the hub, so it doesn't seem at fault for the wreck here. As a Rad Power bike owner myself, I don't buy the second claim either. The most likely cause here would be user error, with the girl operating the bike continuing to pedal on the downhill, causing the hub motor to engage up until the governor's 20mph limit. (She also could have been engaging the throttle, but if she was breaking, that would be VERY difficult for an 11-year-old's hands to do on a Rad Power. Keeping the throttle engaged while also braking is not exactly easy for a full-grown hand to do given the design. I don't see a kid doing it.)
