Here’s how your friend can claim the free trial month (available until 10/31):
If you're new to Citi Bike, visit citibikenyc.com/trycitibike and enter code welcome2citibike
The free trial will last 30 days from signup and is only available to new Citi Bike members. You will not receive a physical key fob for this membership — instead, download or open the latest version of the Lyft app and connect your membership there. After 30 days, you will automatically begin an Annual Membership at $169 plus tax for a year of Citi Bike unless you turn off auto-renew in your account settings.
