London commuters are ditching the Tube and buses - for an alternative that will generally be illegal.
Since the pandemic began, increasing numbers have been turning to e-scooters.
Costing 400 dollars upwards, they have a top speed of around 15 miles an hour
Erica Klose works in the city and is an e-scooter convert.
"Why not join the bandwagon like everybody else and become eco-friendly as well and be able to be safe. I just don't like to be on top of people in the tubes because I work in the city and it does get pretty crowded in the tubes when you get to work in the morning."
But there are challenges for the e-scooter revolution.
Unless it is rented and is part of a government trial, it is illegal to ride one on a public road.
And questions remain about how to regulate motorised scooters, whether people would need a driving license, and how they are insured.
Transport Minister Grant Shapps in May brought forward trials of rental e-scooters in London to next spring.
Scooter retailer Harvey Malik believes the trend is here to stay.
"Obviously Covid-19 being a huge factor for why it's kind of grown massively but people don't want that face to face contact again like I said and they just want to like stay away from everyone while they're transporting and scooters, electric bikes there all amazing ways of doing this."
Around 30 trials are already under way in other parts of the country.
and the results will help inform a decision on whether and how e-scooters might be legalised on roads.
Some in the e-scooter trade say the government is moving too slowly on the issue.
Their popularity is rising elsewhere too.
Paris last year imposed restrictions though, with fines for driving them on the pavement or parking them in doorways.
After two deaths and scores of injuries, residents had become increasingly vocal against e-scooters.
