Lime
One free unlock
Get one free unlock coupon, a $1 value, when you sign up for Lime for the first time and use a friend’s Lime referral code.
To apply your friend’s Lime referral code, in the Lime app, tap the “☰” icon in the top left, then “Wallet”, then “Promos”, then the “Add Promo” button at the bottom and enter the code.
Once you take your first scooter or bike ride, the referrer gets a coupon for one free unlock as well.
