The referrer earns a matching £4 once the new rider completes their first paid ride; existing riders can earn up to 40 referrals. Terms confirmed against Lime's help centre, May 2026. ## Quick facts - Canonical URL: https://honestcodes.co.uk/codes/lime - Referral link: https://lime.bike/referral_signin/RRZ2ZIZTGZA - Code: `RRZ2ZIZTGZA` - Bonus: £4 ride bonus each side - Category: transport - Status: live - Last verified: 2026-05-27 - Eligible region: United Kingdom ## Benefit £4 off your first Lime ride in the UK when you join via this invite — the credit auto-applies to the first ride and any unused portion is forfeited.

It is the largest shared-mobility operator in the world by ridership, with roughly **270,000 vehicles** deployed across about **280 cities** at the end of 2024 and more than **750 million cumulative rides** since launch. In May 2026 the company filed for an initial public offering on Nasdaq under the ticker **LIME**, reporting full-year 2025 revenue of **$886.7 million**. In the UK, Lime is the most visible micromobility brand by some distance. The bright-green e-bikes have been a feature of central London since mid-2021 and now appear across most boroughs that have signed an operator agreement with Lime — a few outer London boroughs (notably Hounslow in 2024 and Richmond upon Thames in early 2025) have since switched their dockless e-bike contracts to Forest. Lime also operates e-bikes and rental e-scooters in **Greater Manchester, Nottingham, Oxford and Milton Keynes**. From **1 April 2026** Lime became the official provider across the **West Midlands** — Birmingham, Coventry, Dudley, Sandwell, Solihull, Walsall and Wolverhampton — following a competitive tender run by Transport for West Midlands. HonestCodes lists Lime because the referral mechanic is permanent, the amount is consistent across UK cities, and the offer is documented in Lime's own help centre rather than relying on a third-party coupon site. ## What you get with the referral The Lime referral programme is a **two-sided £4**. A new rider who joins via an invite link receives a £4 coupon at sign-up, which auto-applies to their first ride. The rider who issued the invite receives their own £4 coupon once the new rider completes that first ride. Both coupons appear under **Wallet → Promos** in the Lime app. The mechanic is best thought of as "two single-ride credits", not "an £8 shared balance". A few specific terms are worth knowing before you plan your first ride: - The £4 applies to **one ride only**. If your first ride costs less than £4 the ride is free; if it costs more, the £4 is deducted from the total (unlock fee plus minutes) and you pay the balance. - **Unused value does not carry over.** A £2.40 ride that uses the coupon will not leave £1.60 on your account. - Coupons **expire 60 days** after they are issued. The referee's coupon starts its clock at sign-up; the referrer's coupon starts when the invited friend takes their first ride. - Coupons are non-transferable. One per account, one per ride. - Each existing rider can earn coupons for up to **40 referrals**. - The coupon applies to whichever Lime product is available in your city — the same code works on e-bikes and rental e-scooters. All of these terms come straight from Lime's published help-centre article on referrals. They have been consistent since the £4 figure was set for the UK market. ## Where Lime operates in the UK Lime's UK service area in 2026 is broader than most riders realise: - **London** — every borough that has signed an operator agreement with Lime, plus the e-scooter operations supervised by Transport for London under the national rental trial. London remains Lime's single largest global market by rides. - **Greater Manchester** — e-bikes and rental e-scooters. - **Nottingham** — e-bikes and rental e-scooters. - **Oxford** — e-bikes and rental e-scooters. - **Milton Keynes** — e-bikes and rental e-scooters. - **West Midlands (from 1 April 2026)** — Birmingham, Coventry, Dudley, Sandwell, Solihull, Walsall, Wolverhampton. More than 2,000 vehicles deployed across the region under a five-year contract with Transport for West Midlands. Rental e-scooters in the region run only in **Birmingham** and on the **University of Warwick campus**; the rest of the region is e-bike only. Local parking rules vary borough by borough. London boroughs increasingly require Lime users to end rides inside marked bays, and several boroughs levy parking penalties on the rider's account if a vehicle is dropped outside one. Lime's in-app map shows live parking zones for each city. ## Lime e-bike vs Lime e-scooter In the UK, Lime operates two distinct vehicle types: - The **Lime e-bike** is an Electrically Assisted Pedal Cycle (EAPC). It is treated identically to any other pedal cycle under UK law: no driving licence, minimum age 14, no helmet requirement, and it can be ridden on the road or in cycle lanes. The current generation — refreshed in late March 2026 with smaller wheels, a lower frame and the battery moved to behind the seat post — is the workhorse of Lime's UK fleet. - The **Lime rental e-scooter** can only be ridden under the **DfT-supervised rental e-scooter trial**. That means it can only be hired in a town that has signed up to the trial, the rider must be 18 or over, and the rider must hold at least a provisional UK driving licence with a category Q entitlement. The trial has been extended five times and currently runs to **May 2028**. The £4 referral coupon does not care which one you ride. It applies to whichever Lime vehicle you unlock first. ## Lime vs Forest vs Voi vs Dott London riders have several rental e-bike apps to choose from. The shortlist usually comes down to four: Lime, Forest, Voi and Dott. - **Lime** — largest fleet, broadest coverage across Zone 1–3 plus the outer boroughs that have signed operator agreements. Pricing as of early 2026 in London is £1 unlock + 31p/minute pay-as-you-go, with LimePass bundles bringing the effective per-minute cost down to 9–13p and the LimePrime monthly subscription giving 20-minute rides for £1.70. - **Forest (HumanForest)** — known for handing out free ride minutes earned through in-app activity, with a £1 unlock fee on additional minutes. Best for short, regular trips by riders who learn to "hunt" free-minute bikes. London-only. - **Voi** — has pushed lower headline rates; a 2025 London campaign advertised "free to unlock" and 18p per minute through specific promotional channels. - **Dott** — smaller London fleet with a reputation for sturdier-feeling bikes (mag wheels, integrated lights, double-legged kickstand) but a more restrictive ride area; sudden no-ride zones in parts of north-east London can cut motors off mid-trip. For most casual riders, the right answer depends on where they live and how long their typical trip is. Lime's edge is sheer density: a Lime is nearly always within sight in central London, and Lime is the only operator listed here with coverage beyond London. ## UK e-scooter trial: legal notes A frequent point of confusion: it is **illegal** to ride a privately-owned e-scooter on public roads, pavements or cycle lanes in the UK. The only legal way to ride an e-scooter in public is through a rental operator that participates in the **DfT-supervised trial**. Lime is one of those operators. The trial currently runs to **May 2028**. If you take a Lime e-scooter under the trial: - You must be **18 or over**. - You must hold at least a **provisional UK driving licence** with a category Q entitlement (covered by AM, A or B licences). - Maximum speed is **15.5 mph** (and some areas cap it lower). - Helmets are **recommended but not legally required**. - You may ride on the road (not motorways) and in cycle lanes. **You must not ride on the pavement.** - One rider per scooter. No phone use. No towing. If you take a Lime e-bike, none of those e-scooter rules apply — a Lime e-bike is treated as a normal pedal cycle. ## Source documentation This page summarises the current Lime UK refer-a-friend programme as published in Lime's help centre. The 60-day expiry, the 40-referral cap, the one-coupon-per-ride mechanic and the £4 figure are all taken from Lime's published help-centre article. UK service area, pricing and West Midlands roll-out figures are cited from the official Transport for West Midlands announcement, Cities Today, Time Out London (LimePrime UK launch coverage) and Wikipedia's Lime (transportation company) entry. The DfT rental e-scooter trial rules are taken from GOV.UK's "Using a rental e-scooter" guidance.

Active and unchanged. As of May 2026 the in-app share screen confirms "Give £4, get £4" for UK accounts, and Lime's help centre confirms the 60-day expiry and the 40-referral cap. HonestCodes re-verifies live offers monthly. ### How do I claim the £4 Lime credit? Open the invite link on the phone you will use to ride. The Lime app opens (or prompts you to install it), the code attaches to your new account automatically, and the £4 coupon appears under Wallet → Promos. It auto-applies to your first ride. ### Does the £4 credit work on Lime e-scooters as well as e-bikes? It does. The coupon is issued at account level and applies to whichever Lime product you unlock first in your city — e-bike or rental e-scooter. It cannot be split across two rides. ### When do I, as the referrer, actually get my £4? As soon as the person you invited completes their first paid ride. The credit then sits in your Wallet for 60 days. You can only earn up to 40 referral coupons in total. ### What happens if my first Lime ride costs less than £4? The ride is free and the unused portion of the £4 coupon is discarded. Lime does not carry the remainder over to a second ride. ### What if my first ride costs more than £4? The coupon deducts £4 from the total (unlock fee plus per-minute charges) and you pay the difference. In central London that means a ride beyond roughly 9–10 minutes pay-as-you-go will run over the £4. ### Do I need a driving licence to ride a Lime e-scooter in the UK? For a rental e-scooter, yes — you must be 18 or over and hold at least a provisional UK driving licence with a category Q entitlement. For a Lime e-bike, no licence is required; standard UK pedal-cycle rules apply (minimum age 14). ### Is a helmet required for Lime in the UK? Not legally — neither the DfT rental e-scooter trial nor UK pedal-cycle law requires a helmet for adults. Lime, the DfT and Cycling UK all recommend wearing one.
