Lime Referral Code — £4 in ride credit

Lime's referral is smaller than Forest's, but it wins on the thing that often matters more: reach. £4 of ride credit is modest, yet Lime runs e-bikes and e-scooters in more UK cities than any other operator we cover, on a generous 60-day window — so for most riders outside central London, it is the offer that actually works where they live.

What you get, and the one-ride rule

The new rider gets a £4 single-ride coupon that lands under Wallet → Promos and auto-applies to the first ride; the referrer gets a matching £4 coupon once that first paid ride completes. The mechanic to understand is one coupon, one ride: if your ride costs under £4 it's free (including the unlock fee), but if it costs more you pay the difference, and any unused value is forfeited — it does not roll over to a second trip. So the way to extract full value is a single ride that lands near the £4 mark.

Both coupons expire 60 days after sign-up — much more breathing room than Forest's seven days — and the qualifying ride has no minimum duration.

Where Lime operates

This is Lime's trump card. It covers London, Greater Manchester, Oxford, Nottingham and Milton Keynes, and from 1 April 2026 added seven West Midlands cities — Birmingham, Coventry, Dudley, Sandwell, Solihull, Walsall and Wolverhampton — under a five-year Transport for West Midlands contract. Lime is the largest shared-mobility operator in the world by ridership, and that scale shows up as the broadest UK footprint here.

E-bike versus e-scooter: the licence difference

The rule that catches people out: a Lime e-bike is an Electrically Assisted Pedal Cycle, so there is no licence requirement (14+, no helmet legally required). A rental e-scooter is different — you must be 18+ with a provisional UK driving licence (category Q), because scooters operate only under the Department for Transport's rental trial (extended to May 2028). Privately owned e-scooters remain illegal on public roads and pavements; only the rental trial fleets are legal to ride.

Pricing context

For reference, London pricing in early 2026 is around £1 to unlock plus 31p a minute pay-as-you-go, with LimePass bundles bringing the effective rate down to roughly 9–13p a minute and a LimePrime subscription offering cheaper short rides. Against that, a £4 coupon is roughly 9–10 minutes of peak London riding — useful, and free for a short hop.

Is there a Lime promo code or discount code?

Lime does have a promo-code field in the app, which makes it different from Forest and Voi — but the referral reward is not delivered through it. The referral coupon is attached when you create the account through the link, and it applies automatically to a qualifying ride rather than needing to be typed.

The practical point is that you cannot stack them. One coupon applies per ride. If you have a referral coupon and a separate promotional code on the account, the app applies a single one to any given trip, so a second code waits for a second ride rather than doubling up on the first.

What people search for	What actually exists
Lime promo code	A real field, but the referral applies automatically
Lime discount code	Occasional city or campaign promotions
Lime voucher code	The £4 coupon, auto-applied to one ride
Lime free unlock code	The coupon covers unlock on a short ride
Lime referral code	£4 after one paid ride within 60 days

Worth understanding about the £4 specifically: because it covers a whole short ride including the unlock fee, it behaves more like a free-trip voucher than a discount. A ride costing under £4 is free outright; a longer one bills only the difference. That makes it better value than the bare number suggests, and better on short journeys than Forest's larger credit, which never covers the unlock.

What we checked

We verify this against Lime's own Help Centre, which documents the £4 figure, the 60-day expiry, the 40-referral cap and the one-coupon-per-ride mechanic, re-checking monthly with a daily link test. We keep the pricing context current because it is exactly the sort of figure that drifts when a city's rate changes.
