We've asked Lime for comment about its response.

None of the injuries to date have been life-threatening, but they have been significant. One rider broke his elbow, while another dislocated his shoulder. There are also reports of cuts and bruises.

The suspension comes at an inopportune moment for Lime. It's aiming for a rapid expansion and just added several European cities in 2018, but it has also grappled with safety issues that included a recall for broken scooters. It might face difficulties extending its reach if it can't convince the public that its scooters are safer than taking a bike or mass transit.
