A year after Lime e-scooters hit our streets the company acknowledges safety remains a big concern - but there are no plans to roll out compulsory helmets

More than 2000 riders have been injured on the popular scooters, which were launched in Auckland a year ago on Tuesday before later being rolled out in other cities.

Earlier this year Auckland Council temporarily pulled them off the streets because of a braking fault.

But, despite the risk and injuries, their popularity continues to climb with more than 2 million rides recorded in Auckland to date.

61.3 per cent of Auckland riders using the motorised scooters to commute to and from work compared to 37 per cent globally.
