Youtuber, personal trainer, and TV presenter Emily Hartridge, 35, died on the morning of July 12.
The crash occurred in Battersea, south of London.
Her personal Instagram account, which has about 44,000 followers, posted an announcement regarding her death:
"Hi everyone. This is a horrible thing to have to say over Instagram but we know many of you were expecting to see Emily today and this is the only way to contact you all at once," it stated.
"Emily was involved in an accident yesterday and passed away. We all loved her to bits and she will never be forgotten. She has touched so many lives it’s hard to imagine things without her. She was a very special person."
Former "Big Brother" host Davina McCall commented on Instagram: “My heart goes out to Emily’s family and friends. Such a shock. Sending you love and prayers.”
Hartridge had about 340,000 subscribers on YouTube and also had a notable presence on Instagram and Twitter. Her channel offered lifestyle advice and interviewed prominent stars such as Hugh Jackman and Eddie Redmayne.
Gizzi Irskine said she was "finding this very very hard to compute."
"Devastating," she added.
Hartridge was also hosting a documentary about turning 30 years of age.
"I think inevitably that [licensing] will happen at some point… It’s inevitable they will be licensed, but we need to make sure we’ve got proper input into how that happens." Brown told Standard.
Currently, there is a $377 (£300) penalty notice and six points punishment on the driver's license for those using e-scooters on pavement or public roads in London.
"I was on the Millennium Bridge the other night and there was some guy on an electric scooter rocketing down the middle. I did think to myself 'This is actually not that safe.'" Brown said to Standard. "I think we have to get some guidance between us and the Department for Transport, because it’s not just a London phenomenon, it’s all over the country."
