New York City bike-share service Citi Bike is to roll out 4,000 electric bicycles over the coming months and will add 13 stations and 2,500 more docks.
The company is waiving the $2 per ride fee until 27 April for members.
After this date, Citi Bike intends to offer free upgrades to members who dock e-bikes at locations which have yet to be revealed along the L train corridor.
Non-members who purchase a single ride, day pass or three-day pass through the Citi Bike app will have to pay $2 per ride,
