Shared scooters barely last a month, report says. But that could change.

It's tough out there for an e-scooter.

The battery-powered vehicles used by most scooter-sharing companies weren't intended for such heavy use. The first generation of shared scooters were mainly from Xioami, and not made with the type of usage scooter rental companies like Bird put the vehicle through. 

Alison Griswold in her Overshare newsletter about the sharing economy crunched the numbers this week from Louisville, Kentucky's scooter-share program. It's based mostly on Bird rides and found between August and December the average lifespan of a scooter there was 28 days.
