There were six serious injuries sustained by shared e-scooter riders in London between 7 June and 26 September, Transport for London data has shown.
TfL has been measuring a number of key metrics since the start of the trial this summer and has now released data for the first four periods.
Between 7 June and 26 September, operators reported six serious injuries suffered by riders, while approximately 255,000 journeys were completed.
The average trip distance in that timeframe was 2.8km, with the average time spent on each journey at 22 minutes.
The permitted fleet size rose to a high of 2,835 between 30 August and 26 September, up from 2,700 between 2 and 29 August.
Between 30 August and 26 September, there was also a high point in terms of trip numbers, with 95,000 journeys completed.
The London trial will run until at least March 2022, after which the data collected from trials across the UK will be used to inform policy.
Lime, TIER, and Dott were the three operators chosen to provide e-scooters for the London trial.
Shared e-scooters are now available in the City of London, Ealing, Hammersmith & Fulham, Kensington & Chelsea, Lambeth, Richmond upon Thames Southwark, Tower Hamlets, and Westminster.
