Jeff Young, a Remuera property valuer, witnessed the crash and told the Herald today that it appeared the scooter's front wheel may have locked up.
Young was driving along Westhaven Drive toward the Harbour Bridge when he saw the Lime scooter rider in the left-hand road lane about 30 to 50 metres in front of him and travelling about 15km/h to 20km/h.
He said the man, who was not wearing a helmet, appeared to get into trouble and veered to the right.
Young said the rider could have been looking around "even looking to hear or see me, thinking 'I'm on the road probably not doing the right thing'."
"In the process he was thrown over. It was like the rear wheel came up and threw him off which probably told me his front wheel must have locked up in some way, which meant the handlebars could have been locked to one side," he said.
Young said the man went over the handlebars and landed on his back, striking his head on the ground about a metre over the centre line in the right hand lane on the road.
"He didn't move at all from that point," said Young, who stopped and was joined by three or four people on the Westhaven boardwalk.
"We could see he was breathing, but there was no movement whatsoever," said Young, saying there was no blood which suggested his injuries were internal.
Young said a woman called the emergency services and they were told not to touch him.
"What we wanted to do was something for him, but they said don't. So for 15 minutes to be standing around directing traffic while this poor guy was just lying there was pretty hard. We did put a jacket on him," he said.
An ambulance arrived 15 to 20 minutes after the accident and the rider was put in a neck brace, placed on a stretcher and put in the ambulance, Young said.
The experience upset Young, who said he thought at the time it was good the man was breathing, but with no movement for 20 minutes knew he might not survive.
Auckland Council bosses temporarily suspended Lime scooters' licence in February amid safety concerns.
The decisions followed a number of recent incidents, some of which have resulted in injuries, caused by the wheels on e-scooters unexpectedly locking.
Witness: Make helmets compulsory for e-scooters
Young believed helmets should be compulsory for all e-scooter riders.
He could not be sure a helmet would have saved the rider in the accident he witnessed "but I would have thought he would have stood a far better chance of surviving".
Young, who has ridden on Lime scooters to the maximum speed, said if you are not wearing a crash helmet it is easy to get unstuck and have an accident.
It is compulsory to wear a helmet while riding a bicycle.
The Auckland death comes after a study, published in the New Zealand Medical Journal last month, said e-scooter crash victims were arriving at hospitals with the sort of traumatic, multiple injuries usually only seen after car crashes.
ACC data shows that claims for e-scooter crashes are still dwarfed by scooter, motorcycle and car crashes. But one thing which stands out in recent research on e-scooter crashes is the severity of the injuries.
Researchers of the study found that the most common crash times were between 8am and 9am and after 6pm, and the most likely age-group to crash were 20-29 year-olds and riders older than 50.
Back in June, a 58-year-old man died riding a Lime but police said he suffered a "medical event" and the matter was referred to the Coroner.
Lime spokeswoman Lauren Mentjox said the entire Lime team was deeply saddened by the news of the tragic death of one of their riders.
"Our thoughts and sympathies are with the rider's family and loved ones during this extremely difficult time.
"At Lime, we take rider safety very seriously and we are working closely with the authorities to support their investigation."
She said Lime was assisting with investigations into the death.
"This includes providing the scooter and its data to them. Out of respect for the people affected, we feel it is inappropriate to comment further at this time."
The death, confirmed by police on Friday, has been referred to the Coroner.
Auckland Council's director of regulatory services, Craig Hobbs, said the council was saddened to learn of this week's death.
"Our thoughts and condolences are with the young man's family and friends at this difficult time."
The council had been in contact with Lime since Monday evening when it first heard reports of an accident in the Westhaven area.
Lime has given a verbal update and provided a report.
"At this stage, Auckland Council has not been given any information which may suggest a mechanical failure of the e-scooter involved in this tragic incident.
"All details relating to the cause of this incident are now with the Coroner and, as such, we are unable to provide any further information at this stage. We can however confirm that we have received no other reports of mechanical issues with e-scooters either prior to or after this incident."
Hobbs said the council was currently in the final six weeks of phase two of its e-scooter trial, and would soon be evaluating what had been learned during the trial.
"Safety has always been paramount to us, and balancing this with significant demand for micro-mobility options is something that many cities around NZ and the world are grappling with."
Today, Auckland mayoral candidate John Tamihere said e-scooters were delivered by Auckland Transport and council planning committee chairman Chris Darby without any thought, saying last week's death could have been foreseen.
In other countries, Tamihere told Newstalk ZB, people had to acknowledge they were over 18, have licence and a helmet before swiping to hire an e-scooter capable to travelling more than 30km/h.
Goff said e-scooters were "not toys, they are vehicles" that have been involved in a lot of crashes, but said he would wait for the Coroner's report into the death and the end of a trial before reviewing the current rules.
"You have got to make sure that the regulatory framework that comes out of central government is as good as it can be so people continue to use scooters but in a safe manner that is safe to themselves and others on shared pathways," Goff said.
