A Quick Code Correction
Before anything else: this page’s older text quoted a $3 credit and code RD54QHO, but that conflicted with Lucy’s actual code card (shown above), which reads $10 Promo Code RA4ZSSR. Per our own house rule, the code card wins over old body copy, so we’ve corrected the figure here — RA4ZSSR is the code on record for this page, not RD54QHO. That said, this code dates to the original LimeBike app from 2018, a year before the company renamed itself Lime and rebuilt its referral system around shareable links instead of typed codes. We can’t confirm a code this old still activates anything.
Lime confirms it currently runs a referral program that pays ride credit or discounts for referring friends and family — but the mechanics are different from the old LimeBike days. Instead of a friend typing in an alphanumeric code, you now share a personal referral link straight from the app, and Lime tracks the signup automatically.
Open the Lime app and tap the gift icon in the top right of the map (or go to the side menu → Wallet → Share Lime).
Send your referral link to a friend.
Code: RA4ZSSR
Your friend creates a new account through that link and takes a ride within 60 days of signing up.
You both get a ride-credit coupon in the Wallet’s Promos section, which applies automatically to your next ride and expires 60 days after it’s earned.
Lime doesn’t publish one fixed dollar amount for this — referral bonuses can vary by city and may not be available everywhere, and each existing rider is capped at 40 referrals. Treat any specific dollar figure you see quoted elsewhere as a snapshot, not a guarantee, since Lime can and does adjust city-by-city promos without notice.
What LimeBike Used to Offer (2018)
Back when this page was written, LimeBike had both dockless bikes and scooters you could unlock and ride around town, and new users could redeem a $10 promo code for ride credit by opening the wallet section and tapping “I have a promo code.” That flow no longer exists under the Lime rebrand — the app now runs entirely on the link-based referral system described above.

Frequently Asked Questions
Does the RA4ZSSR code still work in the Lime app?
We can’t confirm it does. It’s an original 2018 LimeBike code, and the app has since rebranded to Lime and rebuilt its referral system around shareable links rather than typed codes. There’s a good chance it simply won’t register anymore.
Is LimeBike the same company as Lime?
Yes — LimeBike renamed itself Lime in 2019. Same company, same app lineage, new name and (eventually) a rebuilt referral system.
How much do I get for referring a friend to Lime now?
Lime doesn’t publish one fixed number — it says referral bonuses can vary by city and aren’t guaranteed everywhere. Check the gift icon in your app for whatever your current market is offering.
What if I want a scooter app with a working invite bonus right now?
Check our Bird invite code page — Bird is alive and comparably huge, though we’ve flagged that Bird’s own referral tracking link is currently broken too, so verify in-app before counting on it.
