Does EN 15194 Cover Battery Safety?
Not in the way UL 2849 does. EN 15194 is the European standard for the cycle: it is what decides whether your bike counts as an EPAC at all, covering assisted speed, rated power, pedal assist and the electrical requirements that go with them. UL 2849 is a North American safety standard aimed squarely at the electrical system as a system, the battery together with the charger, the controller and the wiring, and how those parts behave together and when they fail. They are two standards about different things, not two versions of the same one.
The practical consequence is the one this page now shows as two separate lines. A bike can be correctly classified as an EPAC, with 250 W and assistance cutting at 25 km/h, and still not carry the certification a particular state or city asks for before it may be sold there. Passing the first test tells you nothing about the second. That is why the checker above reports classification and certification apart from each other, and why a green verdict on one is not a green verdict on both.
UL 2849 or UL 2271: Which Mark Is on Your Bike?
UL 2271 covers the battery pack. UL 2849 covers the whole electrical system that the pack sits in. Both are real certifications and both mean a laboratory tested something, but they are not interchangeable claims, and the difference is where most buying mistakes happen.
The trap is the phrasing. A listing that advertises a UL certified battery, or UL cells, may be describing cells bought certified and then assembled into a pack that nobody tested, or a pack certified on its own and wired to a charger and controller that were never assessed with it. Neither is the same as a bike certified as a system. Look for the standard number rather than the word UL: it is printed on the battery casing and often repeated on a frame label near the head tube or the bottom bracket. If you cannot find a number, treat the bike as uncertified until the manufacturer tells you otherwise in writing.
Where the rules stand. California has legislated certification for e-bikes and batteries sold in the state through SB 1271, and New York City requires certification for bikes and batteries offered for sale through Local Law 39. Most other states have no statute of their own so far, though retailers increasingly ask for UL 2849 anyway. We are naming these laws rather than restating them: we are not quoting their scope, their exemptions or their effective dates here, because that is exactly the detail that changes and that a summary gets wrong. Position as of August 2026, and your local authority decides. What certification is protecting you from is set out in the battery safety section, and if a pack has already started to swell, read what to do with it before anything else. Planning a replacement pack is covered on the battery life page.
Frequently asked questions
Does EN 15194 cover battery safety?
Not the way UL 2849 does. EN 15194 is the European standard for the cycle: assisted speed, rated power, pedal assist only, and the electrical requirements that go with them. UL 2849 is a North American safety standard for the electrical system as a whole, the battery together with the charger, controller and wiring, and how they behave when something fails. A bike can be a correctly classified EPAC and still not carry the certification a given state or city asks for, which is why the checker above reports classification and certification as two separate lines.
What is the difference between UL 2849 and UL 2271?
UL 2271 covers the battery pack on its own. UL 2849 covers the whole electrical system the pack sits in: battery, charger, controller and wiring, assessed together. Both are real certifications, but a listing advertising a UL certified battery or UL cells is not making the same claim as a bike certified as a system. Look for the standard number on the battery casing or the frame label rather than the word UL.
Is my e-bike legal in California?
Two questions decide it, and they are independent. First, classification: California uses the three class system, so your motor power, assisted speed and whether you have a throttle put the bike in Class 1, 2 or 3, and the class sets where you may ride. Second, certification: California has legislated safety certification for e-bikes and batteries sold in the state through SB 1271. We name the law rather than restating its scope or dates, because those are the details that change; check the current requirement with the state before buying. Use the checker above for both lines.
Which e-bike class am I allowed to ride on bike paths?
Class 1, pedal assist cutting off at 20 mph, is the class most widely allowed on bike paths and shared use trails. Class 2 adds a throttle to 20 mph and is usually treated like Class 1 on roads but excluded more often from natural surface trails. Class 3 assists to 28 mph, is normally fine on roads and in bike lanes, and is frequently barred from shared use paths, with several states attaching a minimum age or helmet requirement. The trail or path manager makes the final call.
What does EN 15194 certified mean?
EN 15194 certified means an e-bike has been tested and meets the European EPAC standard: 250W maximum continuous motor power, 25 km/h speed cutoff, and pedal assist only. Certified e-bikes are classified as regular bicycles in the EU and do not require registration, insurance, or a driving licence. The certification is issued by accredited testing laboratories.
Is a 250W 25 km/h e-bike legal in Europe?
Yes, provided it also uses pedal assist only (no throttle beyond walk assist at 6 km/h). These are the three core requirements of EN 15194. An e-bike meeting all three criteria is legal throughout the European Union without registration or insurance.
What is the difference between EPAC and S-Pedelec?
EPAC (Electrically Power Assisted Cycle) under EN 15194 is limited to 250W and 25 km/h, classified as a bicycle. S-Pedelec (Speed Pedelec) can have up to 4000W and assist up to 45 km/h, classified as a motor vehicle under EU Regulation 168/2013, requiring type approval, registration, insurance, helmet, and a driving licence.
Are e-bikes with throttles legal in the EU?
No. Under EN 15194, the motor must only engage when the rider is pedaling. A walk-assist throttle up to 6 km/h is the only exception. E-bikes with full throttle capability are classified as mopeds in the EU and require type approval and registration. In the UK and US, throttle rules differ, use the checker above to verify your specific configuration.

Is EN 15194 the same in the UK after Brexit?
The UK adopted its own EAPC (Electrically Assisted Pedal Cycle) regulations, but the core requirements are nearly identical to EN 15194: 250W continuous, 15.5 mph (25 km/h), pedal assist only. The main difference is the regulatory framework, UK uses SI 2015/24 instead of EU directives. In practice, an EN 15194 compliant e-bike is also legal in the UK.
Is my e-bike legal in the EU?
In the EU, an electric bicycle is classified as an EPAC (Electrically Power Assisted Cycle) and requires no registration, insurance, or licence if it meets three conditions: maximum continuous motor power of 250W, motor assistance cuts off at 25 km/h, and the motor only assists when pedalling (no throttle-only operation). An e-bike that goes beyond any of these limits stops being treated as a bicycle and falls into the motor vehicle categories instead, with registration, insurance and a licence. Which category depends on which limit is exceeded and by how much: a speed pedelec assisting to 45 km/h sits in a different one from a bike that merely exceeds 250W.
What is the maximum motor power for an e-bike in the EU?
Under EN 15194:2017, the maximum continuous rated power for an EPAC (legal e-bike) in the EU is 250 watts. This is the continuous rated output, not peak power. Many e-bike motors can produce 500–700W peak power temporarily during acceleration, this does not make them illegal as long as the continuous rated power does not exceed 250W. Check your motor's specification sheet for the continuous rated power figure.
Is a throttle e-bike legal in the EU?
No. EU law (EN 15194) requires that the motor only provides assistance when the rider is pedalling. A throttle that propels the bike without pedalling classifies the vehicle as a moped regardless of motor power. Throttle e-bikes are legal in the US (as Class 2) and some other markets but not in the EU or UK for road use without registration. Some EU e-bikes have a "walk assist" mode (max 6 km/h) which is legal.
What happens if my e-bike exceeds 25 km/h assistance?
If the motor continues assisting above 25 km/h, the bike is no longer an EPAC and is treated as a motor vehicle under EU law, in one of the moped categories rather than as a bicycle. Riding it on public roads without registration, insurance, and the appropriate driving licence (AM category in most EU countries) is illegal. Police can confiscate the vehicle and issue fines. "Speed unlocking" or "derestricting" an e-bike, modifying it to exceed the 25 km/h limit, invalidates the CE certification and voids insurance.
What is EN 15194 certification?
EN 15194:2017 is the European harmonised standard for EPACs (Electrically Power Assisted Cycles). It defines technical requirements and test methods for e-bikes including electrical safety, motor power limits, speed assistance limits, and pedal sensing requirements. E-bikes sold in the EU must carry the CE mark indicating compliance with EN 15194 and other applicable directives. The standard is enforced through market surveillance by national authorities.
Do EU e-bike rules apply in the UK after Brexit?
Yes. The UK retained the same EAPC (Electrically Assisted Pedal Cycle) rules as the EU after Brexit: maximum 250W continuous power, assistance cut-off at 25 km/h (15.5 mph), and pedal sensing required. The UK uses its own UKCA mark rather than the EU CE mark for newly certified products. Practically, the technical requirements are identical to EN 15194. UK riders face the same restrictions as EU riders.
Are speed pedelecs legal in the EU?
Speed pedelecs, e-bikes with assistance up to 45 km/h and motors up to 500W, are legal in most EU countries but are classified as L1e-B (fast mopeds). They require type approval, registration, insurance, a minimum AM driving licence (equivalent to moped licence), and the rider must wear a helmet. They are not permitted on cycle paths, they must use the road. Rules vary slightly between EU member states.
Can I modify my e-bike to go faster legally?
No. Modifying an e-bike to remove the speed limiter or increase power beyond 250W continuous makes it non-compliant with EN 15194, invalidates the CE certification, voids the manufacturer warranty, and classifies it as an unregistered moped, illegal to ride on public roads. If you need higher speed, a speed pedelec (L1e-B) is the legal route, which requires registration and a driving licence.
