Why compliance is now a market-entry decision, not a documentation task
The numbers explain the pressure. The European e-bike market reached roughly €35 billion in 2024 and is projected to hit €56 billion by 2028; the US market sat at USD 17.5 billion and is expected to roughly double to USD 35 billion in the same window. As volume rises, so does scrutiny — New York City, San Francisco and several EU member states have already moved to require certified electrical systems on every e-bike sold, and major retail platforms have followed. Non-compliant SKUs face delisting, customs holds, product seizure and, increasingly, civil liability when a battery incident occurs.
For B2B buyers, that means two things. First, the certification you choose is dictated by your destination market, not by what your factory happens to already hold. Second, certification has to be planned at the design stage — battery geometry, BMS architecture, charger pinout and even cable harness routing all influence whether a unit passes UL 2849 or EN 15194 the first time. Re-spinning a frame or battery pack after a failed test typically adds 6–12 weeks and meaningful tooling cost, which is why experienced OEM partners now treat the compliance plan as a deliverable on day one.
"Battery certification does not equal full vehicle compliance, and a CE mark on the box does not mean the bike is CE compliant. Both EN 15194 and UL 2849 are system-level standards — the battery, BMS, charger, motor and controller are tested as one product."
EN 15194: the EU baseline for EPAC bicycles
EN 15194 is the harmonised standard for Electrically Power Assisted Cycles (EPACs) under the EU framework. To stay inside its scope, the e-bike must use a motor with a maximum continuous rated power of 250 W, must cut assistance at 25 km/h when the rider stops pedalling, must have a maximum saddle height of at least 635 mm, and must be intended for use on public roads. Anything outside that envelope — throttle-only operation above 6 km/h, higher continuous power, or higher cut-off speed — falls under Regulation (EU) 168/2013 and triggers full L1e-A or L1e-B type approval, which is a much heavier process.
EN 15194 covers electrical safety (LVD-aligned), mechanical safety (frame strength, fork, handlebar, brake performance, lighting), electromagnetic compatibility (EN 55014-1/-2, EN 61000 series) and software/functional safety of the assist system. The on-board charger and battery sub-system must also meet the standard’s requirements, and where applicable EN 50604-1 is used for the lithium battery itself. Manufacturers are responsible for compiling a CE technical file — design documents, risk assessment, test reports, user instructions and a Declaration of Conformity — and for affixing CE marking together with a traceable model identifier.
UL 2849: the US system-level safety standard
UL 2849 is the Standard for Electrical Systems for eBikes published by UL Solutions. Unlike EN 15194 it is not a law — it is a voluntary standard — but in practice it has become a hard market-entry requirement: New York City Local Law 39 mandates UL 2849 (or equivalent) certification for any e-bike sold or rented in the city, several other US municipalities have followed, and Amazon, Walmart and major specialty retailers now require it for listing. Insurers also use it as a baseline for product liability coverage.
The standard evaluates the complete electrical drive system as one unit: battery pack, BMS, charger, motor, controller, wiring and connectors. Battery cells must already hold UL 2271 certification, and the pack-level testing covers overcharge, short-circuit, forced discharge, drop, vibration, thermal cycling, water exposure, and a propagation test designed to confirm a single-cell thermal runaway will not cascade into a full-pack fire. Critical plastics must meet UL 94 V-0 flammability, and FCC Part 15 EMC testing is run alongside. Certification is issued by UL Solutions or a qualified Nationally Recognized Testing Laboratory (NRTL); typical lead time is 8–12 weeks for a design that was engineered against the standard from the start, and considerably longer for designs that need rework.
EN 15194 vs UL 2849 — key requirements at a glance
| Category | EN 15194 (EU) | UL 2849 (US) |
|---|---|---|
| Legal status | Harmonised standard under EU Machinery Regulation; CE mandatory | Voluntary, but required by NYC LL39, Amazon, Walmart |

What changed in 2026: the EU Batteries Regulation and the digital battery passport
Brands that built their compliance plan around CE + EN 15194 alone are now incomplete. Regulation (EU) 2023/1542, the new EU Batteries Regulation, classes most e-bike packs as Light Means of Transport (LMT) batteries — sealed batteries up to 25 kg powering wheeled vehicles. From 2026 onward, LMT batteries placed on the EU market must comply with new performance, durability, removability and labelling requirements, and from February 2027 they must carry a digital battery passport accessible via a QR code on the pack.
That passport is not a marketing leaflet. It must contain the cell chemistry, rated capacity, state-of-health metrics, carbon footprint declaration, supply-chain due-diligence statement, recycled-content percentages and end-of-life handling instructions. Three harmonised standards underpin the requirements: prEN 18060 (rechargeable batteries with internal energy storage for road vehicles), prEN 18061 (safe repair and reuse of EV/LMT batteries), and the prEN 50XXX series on LMT performance and durability. Practically, this means OEMs need to design packs that are removable for service, traceable at cell level, and documented with carbon-footprint data — decisions that affect cell sourcing, BMS firmware and even the housing CMF, all of which must be locked in before tooling.
Five compliance mistakes we see brands repeat
After hundreds of OEM/ODM projects, the same expensive errors keep showing up. First, treating the cell certificate as proof of pack compliance — a UL 2271-listed cell does not make the pack UL 2271 listed, let alone the system UL 2849 listed. Second, assuming a CE self-declaration covers EN 15194 — harmonised testing through a competent lab is required, and self-declaration without test reports is a textbook customs hold. Third, sharing a single test report across two markets — UL 2849 and EN 15194 are not interchangeable; pack chemistry, BMS firmware and EMC tuning often differ between the US and EU SKUs. Fourth, leaving certification until after pre-production samples are approved, which forces redesigns once the lab finds an isolation, leakage-current or thermal-runaway issue. Fifth, ignoring REACH and the ADR (UN 38.3) on the logistics side, which can ground an otherwise fully certified container at port.
Decide EU-only, US-only or dual-market on day one. The choice changes the cell, the BMS firmware and the charger SKU; pretending it is a final-stage decision is the single most expensive mistake we see.
Both EN 15194 and UL 2849 certify the integrated drive system. Mixing a certified motor with an uncertified BMS does not yield a certified bike — the lab tests the combination you ship.
Removable packs, cell-level traceability, carbon-footprint data and a QR-readable passport are not optional after February 2027. Designs locked in 2026 should already accommodate them.
A partner that already holds EN 15194 and UL 2849 on its own platforms can transfer engineering know-how to your custom SKU; one that only borrows reports from sister factories cannot defend you in an audit.
How TXED bakes compliance into OEM/ODM from day one
As an e-bike factory serving global brands, TXED treats certification as an engineering deliverable rather than a downstream service. Every OEM/ODM project kicks off with a target-market matrix — EN 15194, UL 2849, AS/NZS, UKCA, or a combination — and the BOM is locked against that matrix before tooling. We work with UL Solutions, TUV, SGS and Intertek for system-level testing, source UL 2271-listed cells and EN 50604-1-aligned packs, and provide brands with the full CE technical file, UL construction record and battery-passport data set under their own labels. The result for our partners is a certified product that ships on time, holds up under retailer audits, and is ready for the EU’s 2027 passport rules without a redesign cycle.
