LONDON, April 29, 2026 — Forest, the London-based micromobility operator, has closed its Series B funding round at £40 million following a £27 million extension announced on 28 April 2026. The round, which began with a £13 million first close in early 2025, includes £17 million in fresh equity from investors such as B8 Venture Partners, Fen Ventures, and Güil Mobility Ventures, alongside £10 million in asset-backed financing from Fintex Capital. The company, founded in 2020 by former Cabify executive Agustin Guilisasti alongside Caroline Seton and Michael Stewart, now serves 1.5 million users and records approximately two million rides per month across 18 London boroughs. The capital injection arrives at a moment when shared e-bikes are demonstrably shifting from discretionary convenience to genuine urban transport infrastructure — a thesis tested in real time during recent Tube strikes, when Forest recorded a 30% jump in rides. This analysis examines Forest's capital strategy, its competitive positioning against established transport incumbents, and the wider implications for urban mobility investment in the United Kingdom.
Executive Summary
Forest's £40 million Series B positions it as one of the most heavily capitalised private micromobility operators in London. The round's structure — blending venture equity with asset-backed debt from Fintex Capital — reflects a maturing financing model for hardware-intensive mobility businesses. The company has installed 2,600 parking bays and plans to deploy further infrastructure investment to improve parking discipline and operational efficiency. With B Corp accreditation and Verra validation, Forest occupies a distinctive sustainability niche that neither Santander Cycles nor Lime currently matches. The 30% ride uplift during recent Tube strikes underscores latent demand for reliable, affordable alternatives to the Underground. At under £1 per day through its CycleSaver scheme, Forest's pricing model directly challenges the economics of both docked bike-share and pay-per-ride competitors.
Key Developments
Funding Architecture and Investor Composition
The Series B's total of £40 million is composed of two distinct tranches. The first close, completed in early 2025, raised £13 million. The second close, announced on 28 April 2026, brought in an additional £27 million. Of this latest tranche, £17 million arrived as equity from B8 Venture Partners, Fen Ventures, and Güil Mobility Ventures — all of whom increased their participation from prior commitments. Fintex Capital contributed £10 million in asset-backed financing, a structure that uses Forest's physical fleet as collateral and preserves founder equity. This dual-track approach — equity plus asset-backed debt — has become increasingly common among micromobility operators that must finance rolling hardware inventories without diluting ownership at punitive valuations. The ratio of roughly 60% equity to 40% debt in this close suggests that Forest's fleet economics are sufficiently proven to attract non-dilutive capital.
Operational Scale and User Metrics
Forest now claims 1.5 million registered users and approximately two million rides per month across 18 London boroughs. Since 2021, the company has provided 110 million free ride minutes through its model of offering 30 free minutes of cycling per day. The CycleSaver scheme makes bikes accessible for under £1 per day, positioning Forest as a budget-friendly commuter option. The company has installed 2,600 dedicated parking bays — a critical infrastructure investment aimed at reducing pavement clutter and improving relationships with local councils. Agustin Guilisasti co-founded the business in 2020 after a period at Cabify, the Madrid-based ride-hailing platform, bringing operational experience from a different corner of the urban mobility market. Co-founders Caroline Seton and Michael Stewart round out the founding team.
Sustainability Credentials
Forest claims to operate its entire fleet — bikes and service vehicles — on renewable energy. The company is one of only two micromobility operators globally to hold B Corp accreditation and the sole operator to have achieved Verra validation, a carbon credit standard typically associated with forestry and energy projects rather than urban transport. These credentials serve a dual purpose: they differentiate Forest from competitors in council procurement conversations and they appeal to a growing cohort of ESG-conscious institutional investors. The B Corp and Verra combination is genuinely unusual in this sector and may prove commercially decisive as London boroughs tighten their environmental criteria for operator licences.
Market Context & Competitive Landscape
Forest vs. Santander Cycles vs. Lime
Forest operates in a London market that includes at least two formidable competitors: Santander Cycles, the docked bike-share scheme backed by Transport for London (TfL), and Lime, the US-headquartered operator with a global footprint spanning more than 280 cities. Santander Cycles benefits from deep TfL integration and brand recognition but remains limited by its docked model, which requires users to start and end journeys at fixed stations across central London. Lime offers dockless flexibility and substantial global scale but lacks Forest's sustainability certifications and its generous free-ride allocation. Forest's vulnerability lies in its geographic concentration: it operates exclusively in London across 18 boroughs, whereas Lime can cross-subsidise from revenues in dozens of international markets. A candid assessment must also acknowledge that £40 million, while significant for a UK micromobility Series B, is modest compared to the hundreds of millions Lime has raised cumulatively since its 2017 founding.

Honest Limitations
Forest's impressive user numbers — 1.5 million registered users and two million monthly rides — must be contextualised. Registered users are not the same as monthly active riders; the conversion rate between the two is not disclosed. The 110 million free ride minutes provided since 2021 represent a significant customer-acquisition cost that will eventually need to be offset by paid usage or ancillary revenue. The company's exclusive London focus limits its addressable market and creates concentration risk if regulatory conditions in the capital change unfavourably. These are not disqualifying weaknesses, but they warrant scrutiny from investors evaluating Forest against operators with broader geographic diversification.
Industry Implications
Urban Transport Policy and Local Government
Forest's expansion has direct relevance for London's City Hall and for borough councils managing competing demands on limited road and pavement space. The installation of 2,600 parking bays addresses one of the most persistent complaints against dockless operators — pavement obstruction — and suggests a collaborative rather than adversarial model for council relationships. During recent Tube strikes, Forest's 30% ride increase demonstrated that shared e-bikes can absorb meaningful commuter demand during public-transport disruptions, a data point with implications for Transport for London's resilience planning.
Financial Services and ESG Investment
Fintex Capital's £10 million asset-backed facility reflects a growing appetite among specialist lenders for mobility-fleet financing. This model — common in automotive leasing — is still relatively novel in micromobility and could open a pathway for institutional investors seeking exposure to urban transport assets without taking venture-level equity risk. Forest's B Corp and Verra credentials also position it within ESG frameworks used by pension funds and insurance companies when evaluating alternative investments. For the broader fintech and transport finance sector, the Fintex deal may serve as a template.
Healthcare and Air Quality
Public health authorities, including the UK Health Security Agency, have repeatedly linked active travel and reduced vehicle emissions to improved respiratory outcomes. Forest's renewable-energy-powered fleet, serving two million rides per month, contributes to modal shift away from internal combustion vehicles. While quantifying the direct health benefit per ride remains methodologically challenging, the aggregate effect of 110 million free ride minutes since 2021 is not trivial in a city where air quality consistently breaches WHO guidelines in multiple boroughs.

The Capital Structure Tells a Story
Our assessment is that the most revealing element of this raise is not the headline figure but the capital mix. The decision to blend £17 million in equity with £10 million in asset-backed debt signals that Forest has reached a level of fleet maturity where lenders can underwrite its hardware. This is a meaningful inflection point. Early-stage micromobility companies typically rely entirely on equity because their unit economics are unproven and their assets — lightweight vehicles subject to vandalism, theft, and weather damage — are difficult to collateralise. Fintex Capital's willingness to provide £10 million against Forest's fleet suggests that vehicle longevity, utilisation rates, and maintenance costs have reached bankable levels. If Forest can continue to attract debt financing at scale, it will be able to expand its fleet more rapidly than equity-only competitors while preserving founder and early-investor ownership. This is the same capital-efficiency playbook that transformed car rental and commercial vehicle leasing in the 1990s, now applied to two-wheeled electric vehicles.
The Free-Ride Model: Acquisition Engine or Margin Drag?
Forest's offer of 30 free minutes per day is generous — arguably the most generous daily allocation among any London e-bike operator. The 110 million free ride minutes delivered since 2021 represent a massive investment in user acquisition and habit formation. The strategic logic is sound: once riders integrate Forest into their daily commute, conversion to paid usage or CycleSaver subscriptions (under £1 per day) becomes a natural step. The risk, however, is that free minutes become an expectation rather than a gateway. If a significant portion of Forest's two million monthly rides fall within the free allocation, per-ride revenue will remain suppressed even as fleet and infrastructure costs scale. We would want to see the ratio of free to paid rides before declaring this model sustainable — a figure the company has not disclosed. Comparable models in other subscription businesses suggest that conversion rates of 5% to 15% from free to paid tiers are typical; Forest's rate likely needs to sit at the upper end of that range to support its cost base.
The Tube Strike Thesis
The 30% ride increase during recent Tube strikes is arguably the single most important data point in Forest's investor narrative. It demonstrates price-insensitive, necessity-driven demand — the kind of usage that underpins transport infrastructure rather than discretionary leisure. If Forest can position itself as a resilient complement to the Underground and bus network, it moves from being a venture-backed consumer brand to something closer to regulated utility infrastructure. That shift would unlock an entirely different tier of capital: infrastructure funds, pension allocations, and potentially even Department for Transport grants. The question is whether Forest can sustain that positioning outside of strike periods, when the convenience premium narrows and competition from the Tube, buses, and walking re-intensifies.

Why This Matters for Industry Stakeholders
For urban transport planners, Forest's 2,600 parking bays and 18-borough coverage offer a template for how dockless operators can integrate with municipal infrastructure rather than burden it. Councils negotiating new operator licences should study the parking-bay model as a condition of market access. For venture capital and growth-equity investors, the Fintex Capital debt tranche demonstrates that asset-backed financing is becoming viable for micromobility fleets — a development that could compress equity dilution across the sector and improve founder returns at exit. For ESG and impact funds, Forest's unique combination of B Corp accreditation and Verra validation sets a benchmark that other operators will struggle to replicate quickly, creating a short-term scarcity premium for sustainability-credentialed mobility assets. For public health officials, the two million monthly rides and 110 million cumulative free ride minutes represent measurable modal shift away from motorised transport in a city with chronic air-quality challenges. The 30% Tube-strike uplift suggests that shared e-bikes can function as emergency transport resilience infrastructure — a consideration that belongs in DfT contingency planning.
Forward Outlook
Forest's immediate priority is geographic expansion within London, but the £40 million war chest also raises questions about potential moves beyond the M25. Cities such as Manchester, Birmingham, and Bristol have active micromobility licensing frameworks that could accommodate a Forest-style dockless e-bike operation. A multi-city UK presence would reduce London concentration risk and improve the company's attractiveness to later-stage investors or strategic acquirers. The regulatory environment remains a variable. The UK government's position on e-scooter legalisation — still formally under review as of April 2026 — will shape the competitive dynamics of the entire micromobility sector. If e-scooters are legalised nationally, operators like Lime may redirect capital towards scooter fleets, potentially reducing competitive pressure on the e-bike segment where Forest is strongest. Conversely, full legalisation could invite new entrants and fragment the market. The most consequential question for Forest over the next 12 to 18 months is whether it can convert its 1.5 million registered users into a base of recurring, paying subscribers at a rate sufficient to reach operating profitability before the Series B capital is exhausted. The CycleSaver model at under £1 per day offers a compelling consumer proposition, but the margin arithmetic at that price point demands exceptional fleet utilisation and low per-vehicle maintenance costs. If Forest's fleet economics hold, a Series C or strategic acquisition by a larger transport group is plausible by late 2027. If they do not, the company joins a long list of well-funded micromobility operators that scaled users without scaling unit economics.
Key Takeaways
• Forest closed its Series B at £40 million on 28 April 2026, comprising £17 million in equity from B8 Venture Partners, Fen Ventures, and Güil Mobility Ventures, plus £10 million in asset-backed financing from Fintex Capital, atop a £13 million first close in early 2025.
• The company serves 1.5 million users, records two million monthly rides across 18 London boroughs, and has delivered 110 million free ride minutes since 2021.
• A 30% ride increase during recent Tube strikes demonstrates that shared e-bikes are transitioning from convenience to essential urban transport infrastructure.
• Forest's B Corp accreditation and Verra validation make it unique among global micromobility operators and increasingly relevant to ESG-focused capital allocators.
• The blended equity-plus-debt capital structure signals fleet-level financial maturity and could serve as a template for other hardware-intensive mobility startups seeking non-dilutive growth capital.

Frequently Asked Questions
How much funding has Forest raised in its Series B round?
Forest closed its Series B at a total of £40 million. The round began with a £13 million first close in early 2025, followed by a £27 million extension announced on 28 April 2026. The latest tranche comprises £17 million in equity from B8 Venture Partners, Fen Ventures, and Güil Mobility Ventures, plus £10 million in asset-backed financing from Fintex Capital. The blended equity-and-debt structure reflects fleet-level maturity in Forest's operations.
How does Forest compare to Santander Cycles and Lime in London?
Forest operates a dockless e-bike model across 18 London boroughs with 1.5 million registered users and two million monthly rides. Santander Cycles, backed by TfL, uses a docked model limited primarily to central London. Lime offers dockless e-bikes and e-scooters with a global network spanning more than 280 cities. Forest differentiates itself through B Corp accreditation, Verra validation, and a free 30-minute daily ride allocation that neither competitor matches.
What makes Forest attractive to ESG-focused investors?
Forest is one of only two micromobility companies globally to hold B Corp accreditation and the sole operator to have achieved Verra validation, a carbon credit standard. Its fleet and service vehicles operate entirely on renewable energy. These certifications position Forest within ESG frameworks used by pension funds and insurance companies, creating a scarcity premium for sustainability-credentialed mobility assets in the investment market.
What is Forest's pricing model for London riders?
Forest offers 30 free minutes of cycling per day to all users, and has delivered 110 million free ride minutes since 2021. Through the CycleSaver subscription scheme, bikes are accessible for under £1 per day, making it one of the most affordable commuter cycling options in London. By comparison, a Santander Cycles day pass costs approximately £2, and Lime charges a per-ride unlock fee plus per-minute rates.
What is Forest's growth outlook beyond 2026?
Forest's immediate focus is expanding infrastructure and coverage within London, having already installed 2,600 parking bays across 18 boroughs. The £40 million Series B could also fund exploration of other UK cities such as Manchester, Birmingham, and Bristol, which have active micromobility licensing frameworks. A Series C or strategic acquisition by a larger transport group is plausible by late 2027 if fleet economics remain sound and user conversion rates from free to paid tiers prove sustainable.
