Protesters took their e-scooters to the prime minister’s home to call for a change to what they called an “outdated” law.
Electric scooters, which usually cost hundreds or even thousands of pounds, are similar to a traditional child’s scooter but are powered by a motor so can reach speeds of 30mph or more.
They have surged in popularity but many people fail to realise they are breaking the law by riding them on roads and pavements. They can legally be used only on private land in the UK.
Riders may face a £300 fixed-penalty notice and six points on their driving licence if caught.
Campaigners said the Road Traffic Act needed updating, and that e-scooters were an environmentally friendly alternative to cars.
But they have prompted safety concerns, which were heightened last month when Emily Hartridge, a television presenter and YouTuber, became the first person in the UK to be killed while riding an e-scooter.
Some UK commenters say e-scooters should have number plates, and that riders should be required to wear helmets, follow all traffic laws and be forced to pay insurance and road tax.
Peter Williams, 22, who organised the protest, said authorities had clamped down on the use of e-scooters.
“We want there to be legislation around this that will make it safer for people and we basically want people to have the option of choosing a green mode of transport rather than using, for example, diesel buses or cars,” he added.
“How is it right to prosecute those who are making a change in our city to reduce congestion, pollution and the risk of death in automotive collisions?”
However, a new American study found e-scooter sharing schemes were not as eco-friendly as they seem.
Researchers at North Carolina State University found that the materials it took to manufacture the frame, wheels and battery, as well as rounding up the scooters, charging them and returning them to the streets at the end of each day created more greenhouse gas emissions than other forms of transport.
At the same time as the Downing Street protest, Oxfordshire police issued the identity of an electric skateboard rider who died after an accident. Bradley Visser, 38, died 10 days later.
The Department for Transport said the government was examining how e-scooters could be regulated for safe use on the road, while still encouraging innovative new forms of transport.
Transport for London said that if the ban on the vehicles ends, maximum speeds and restrictions on where they can be ridden must be among new safeguards.
