Authorities have issued a safety plea for e-scooter users after a rider died from head injuries in inner Brisbane.
The man in his 60s went over the handlebars and hit his head after clipping a gutter in Fortitude Valley early on Friday morning.
Companions provided first aid before paramedics arrived but the man died at the scene.
He appeared to have been travelling "at speed", Queensland Ambulance Service paramedic James Wylie said.
"Unfortunately when we arrived, the patient was in cardiac arrest," he said.
QAS Assistant Commissioner Claire Bertenshaw said she was unsure whether the man was wearing a helmet but the incident was a reminder to ride safely.
"When someone's riding an e-scooter we need to have that helmet on," she told reporters on Friday.
"We can't have it on the handlebars, it can't be hanging around someone's waist, it needs to be on their head and done up.
"We also need to be aware of speed - people need to take some responsibility in going slowly with a helmet on and also be worried about pedestrians."
At least one rider a day is taken to hospital after an e-scooter accident, according to a Queensland Health report released in 2021.
It found at least 25 per cent of injuries involved alcohol and 10 per cent were due to riders not wearing a helmet.
Males make up the majority of injured riders, at 71 per cent with an average age of 33, while 39 per cent of accidents occurred between 9pm and 5am.
A Queensland Police unit is investigating and has asked anyone with dashcam or CCTV footage of the incident to come forward.
