Eunorau FAT-HD 1.0 Pro Review 2026: 1,200 Wh, 375 lb

48V 1000 W Bafang mid-drive · 160 N·m · 1,200 Wh · 20 mph, unlockable · 375 lb payload · 78.7 lb · $1,999 · verified September 6, 2026

Quick Answer — The Eunorau FAT-HD 1.0 Pro is a $1,999 fat-tire hunting e-bike with a 1,000 W Bafang mid-drive rated at 160 N·m and a 1,200 Wh battery. Buy it if you haul gear down fire roads on land where you set the rules, and see our hunting e-bike guide for how it fits the other thirteen we sell by ground and by state. Its 1,000 W motor sits outside the e-bike definition in 44 of 51 US jurisdictions.

That last line is the whole planning problem, and it is answerable state by state. The other thing worth knowing before you read a word anywhere else: the only editorial test of this bike was published in March 2019 and describes a machine with a 15.6 Ah battery and a 28 mph top speed. Eunorau ships 25 Ah and 20 mph today.

Who the FAT-HD 1.0 Pro is for

A $1,999 bike carrying more battery than machines at twice the price, and a motor rating that decides where you are allowed to ride it. Both facts are on this page.

Eunorau's own photograph of the Gray build, and the source for every component named on this page. The rack, the fenders and the kickstand are all standard fitment.

Buy it if your riding ends at a gate you have the key to. This is a machine for fire roads, food plots, sand, snow and the long loaded haul back out — and the case for it rests on two numbers that are unusual at $1,999: 1,200 watt-hours of battery and a 375 lb payload.

The mid-drive is the reason it climbs. Eunorau specifies a 48V 1,000 W Bafang brushless mid motor rated at 160 N·m, sitting between the cranks instead of inside a wheel.

Power routed through the chain gets multiplied by whatever gear you are in, the same way your legs get multiplied in a low gear. A mid-drive therefore holds a steep loose climb where a hub motor of the same rating runs out of leverage, which is why Eunorau fits one here. If the difference is new to you, our e-bike motor guide works through it properly.

The motor housing sits at the bottom bracket and drives the 46T chainring. Everything the motor produces passes through the seven-speed cassette behind it.

Do not buy it as a commuter. The published 1,000 W is above the ceiling in the e-bike definition of 44 US jurisdictions, and a daily road ride is precisely the use that ceiling governs. If your riding is public bike paths and painted lanes, the Eunorau FLASH LITE ST is the 750 W, 20 mph machine built for that job, and we reviewed it here.

Do not buy it as a trail bike either. The RST Guide fork gives 100 mm of travel and there is no rear suspension at all, so what smooths a rough descent here is tire volume, not damping. Riders who want a bike for singletrack should start with the SPECTER-S 3.0 and our electric mountain bike guide.

How we verified this Eunorau FAT-HD 1.0 Pro review

Verification basis: every specification on this page is confirmed at the manufacturer and recomputed. That is said first because it fixes what the rest of the page claims. Each figure below is either Eunorau's own published specification, a primary record such as a statute or a federal recall database, or arithmetic over those — and each is linked to the document it came from.

Every specification was read from Eunorau's own product page on 6 September 2026 and saved to disk, so each figure can be checked against what that page said on the day.

Prices and stock come from our own listing through the Shopify Admin API on the same date.

The 2019 comparison rests on a document, and it is on disk. Electric Bike Review's page publishes a datePublished of 19 March 2019 and carries Model Year: 2019 as a labelled field. Its specification values — 15.6 Ah, 748.8 Wh, 28 mph, 62 lb, $2,399 — were read out of those same labelled fields, never paraphrased from its prose.

The legality screen is measured, and the instrument was tested before it was believed. Eunorau's published 1,000 W and 20 mph were run against a table of all 51 US e-bike definitions, each row carrying its own statutory citation. Before trusting the result we ran the same table at 750 W and at 3,000 W: it returned 27 qualifying jurisdictions and zero respectively. A screen that discriminates across that range is measuring something; one that returned the same answer at every power level would not be.

Where our screen disagreed with the AI answers, we went to the statute. Five states were re-read at their own publishers on 6 September 2026 and each is quoted in the references.

A correction we made to our own method, before it reached this page. The Georgia Department of Public Safety's website appeared at first to publish a 1,000 W figure, which would have been a genuine conflict between a state's code and its enforcing agency. It was not. Reading that agency's own definitions document, in place of a summary of its web page, gives "an electric motor having a power output of not more than 750 watts" — the same figure as the code. The number here is 750, and there is no conflict to report.

We measured the demand this page answers. We harvested 1,061 rows from three independent programmatic sources — 821 autocomplete completions, 67 related searches and 173 headings from pages currently ranking — of which 60 unique questions touch this bike or the specifications that decide it. On top of that we ran a six-prompt AI-answer panel and saved its raw output verbatim.

No search volume appears anywhere on this page. Our Semrush units are exhausted and no dated export exists inside the freshness window, so we publish no volume figure, no difficulty score and no "high-intent" claim. Absence of a number here means we did not measure one.

The arithmetic is reproducible. Every derived figure comes from a script that takes Eunorau's published numbers as inputs and prints its method beside each result. Nothing on this page is a number recalled from a previous run.

Eunorau FAT-HD 1.0 Pro specifications

Every row is Eunorau's published figure, retrieved 6 September 2026.

One detail is legible in Eunorau's own photographs but absent from the written specification: the tires are Kenda Juggernaut casings, with "30 TPI CASING WIRE BEAD" printed on the sidewall. The spec table records only "Kenda Tires 26" x 4.0"".

The cockpit carries the L183 display, a thumb throttle and the hydraulic levers. The rotor visible at the front wheel is the 180 mm.

Geometry, as published

Eunorau publishes a full geometry table, which is not universal at this price. The 30.3 in standover is the number to hold against your inseam.

The bike in the only review of it no longer exists

Search this model and you will find one editorial test. It is Electric Bike Review's, and its own header field reads Model Year: 2019. It was published on 19 March 2019 at an MSRP of $2,399.

That page is still the authority every AI answer draws on, and the bike it describes is not the bike Eunorau sells.

The energy arithmetic, stated so you can check it. 48 volts × 15.6 amp-hours is 748.8 watt-hours, which agrees with the watt-hour figure Electric Bike Review publishes in its own field — a useful confirmation that the method is right before it is applied to the current bike. 48 volts × 25 amp-hours is 1,200 watt-hours. The difference is 451.2 Wh, or 60.3% more.

Put price beside it. The 2019 machine offered 748.8 Wh for $2,399, which is 0.31 watt-hours per dollar. Today's offers 1,200 Wh for $1,999, which is 0.60. That is 1.92 times the energy per dollar of the bike in the review that still ranks.

The brake note deserves its own sentence. The 2019 test's stated criticism was mechanical discs needing constant adjustment against the weight and speed of the bike, and its advice was to fit hydraulics. Eunorau's current specification is hydraulic front and rear, 180 mm and 160 mm, with a cut-off that kills the motor when you pull either lever. The complaint in the review has been answered by the product.

The Camo build at $2,099. Mechanically it is the Gray bike; the finish is the difference.

1,000 watts, and all 51 US jurisdictions

This is the section to read before the spec sheet, because it decides whether the bike suits the life you actually live.

Eunorau publishes 1,000 W nominal and 20 mph. We screened those two figures against every US e-bike definition — all 50 states and the District of Columbia — with each row carrying its own statutory citation.

The reason is almost always the same single number. The federal definition of a low-speed electric bicycle at 15 U.S.C. § 2085 stops at 750 watts, most states adopted that ceiling, and 1,000 is above it. Speed is not what excludes this bike — at 20 mph it is inside every speed cap in the country. Wattage alone does it.

The four exceptions divide into two kinds. DC, Montana and Oregon simply write no wattage ceiling into their definitions, so a 1,000 W motor has nothing to exceed. Rhode Island is the only state whose ceiling is a number this bike passes: R.I. Gen. Laws § 31-1-3 sets it at 1,492 watts.

Outside the bicycle definition does not mean unlawful. It means a different set of rules applies, and three states name which in their own words. South Carolina writes the destination into its own text: a two- or three-wheeler "designed to have an input exceeding 750 watts and no more than 1500 watts" is a moped, and a moped is a motor vehicle. Virginia reads the same way, its moped category capped at "an input of 1500 watts or less". Maine puts it in a moped class defined as "an electric motor with a capacity under 1,500 watts". In those states the practical questions are registration, a license and where mopeds may be ridden — not whether you may own the bike.

For the broader picture, our 1,000 W e-bike guide works through the category, and our e-bike law hub carries the state pages.

What AI search is telling buyers, and what the statutes say

Asked "are 1000w ebikes legal" on 6 September 2026, the engines returned a confident list drawn entirely from retailer marketing blogs:

"Six states specifically allow eBikes to have a max power of 1000W; these are Georgia, Kansas, Minnesota, Oklahoma, Oregon, and Virginia."

We read all six at their own publishers. Five of them are wrong.

Oregon is the only state on that list where a 1,000 W bike is an electric bicycle under the federal framework's 750 W benchmark. If you live in one of the other five and bought on the strength of that answer, you bought on a number nobody checked.

California, and one word on the spec sheet

California is worth naming separately because it turns on wording where the other states turn on arithmetic. Cal. Veh. Code § 312.5(d)(1) removes from the definition any vehicle

"intended by the manufacturer to be modifiable to attain a speed greater than 20 miles per hour on motor power alone or to attain more than 750 watts of power".

Eunorau's own specification grid describes this bike's limit as "Class 2 Speed limited Unlockable" — the manufacturer itself calling the limit raisable.

Whether that publication is what the section means by "intended by the manufacturer to be modifiable" is California's question to answer, and we have found no California decision that settles it. The verdict does not change either way: at 1,000 W the bike is already above California's ceiling. What changes is which clause does the work.

What "Class 2, unlockable" actually asks of you

Unlocking an e-bike's speed limit is one of the most-searched questions in the category, and the answers currently ranking are button sequences and access codes with a one-line reminder to check local rules. That reminder is doing more work than it looks.

On this bike the published limit is 20 mph and Eunorau describes it as unlockable. Raising it changes three things.

Nothing about the wattage question. At 1,000 W the bike is already outside the definition in 44 jurisdictions before the speed setting is touched. Unlocking does not create that situation and re-locking does not resolve it.

Everything about the second ground. In the states that do write a speed ceiling into their classes, a raised limit adds a second, independent reason the bike falls outside — and it is the ground that is visible from the roadside. A wattage rating is a label; a speed is a thing a person can observe.

And it is the version you cannot undo after the fact. A limit you raised is a setting you chose, which is a different conversation from a rating printed by a factory.

The honest instruction is short. Leave it at 20 mph on any public road, path or trail. Raise it, if at all, only on land where you set the rules — and be aware that our reading of the specification is the maker's own description of the bike, and we have not carried the procedure out ourselves.

The 60-mile claim, and the arithmetic underneath it

Eunorau publishes "Up to 60 Miles". Divide that claim by the battery it ships with and you can see what it assumes.

1,200 watt-hours across 60 miles is 20.0 watt-hours per mile. The headline rests on that efficiency.

The comparison cuts a way most readers will not expect. The 2019 machine claimed a 45-mile maximum on 748.8 Wh, which works out at 16.6 Wh per mile — a more optimistic assumption than the one on today's page. The current claim is the more conservative of the two, which is not what usually happens to a range figure over seven years.

The 25 Ah pack sits in the downtube. It is the single component that most separates this bike from the one in the 2019 review, and from both bikes the engines recommend instead.

Twenty watt-hours a mile is still a best case: a light rider, firm ground, low assist, no throttle, no load. A 78.7 lb fat bike with a thumb throttle, carrying gear, on soft ground, does not live there. Applying figures that better match how this bike gets used:

Plan on 34 to 48 miles for the kind of riding this bike is sold for, and treat 60 as the number you might see on a flat gravel road with a tailwind and a light pack. Even the pessimistic end of that band is more usable range than the 2019 bike's claim.

What 375 pounds leaves you

The 375 lb total payload capacity is one of the strongest figures on the spec sheet, and it is worth reading carefully because "total payload" is not a standardized phrase.

The bike weighs 78.7 lb. If the 375 lb figure is the capacity above the machine — the ordinary reading of a payload rating — then rider plus gear can total 375 lb. If it is a gross weight including the bike, the usable figure is 296.3 lb. Eunorau does not say which, so both readings appear here and we use the conservative one when it matters.

Either way, this is a lot of capacity in this price band. It is 75 lb more than the Rambo Rebel 2.0 publishes and 50 lb more than the QuietKat Apex XD, both of which cost over $3,600. For riders who put capacity first, our guide for heavier riders works through the whole shelf.

The rear rack is a factory platform, not an accessory, which matters if the load is the reason you are buying.

Cadence, not torque: what the BBSHD decides

This is the fit fact most likely to surprise someone stepping up from a mid-priced commuter, and it is a property of the motor platform, shared by every brand that fits one.

Eunorau's specification lists a "Bafang BBSHD Gear Sensor" and "0~5 level pedal assist". It does not claim a torque sensor, and the 2019 test recorded the same thing in its own drive-mode field: "Cadence Sensing Pedal Assist". Owner forums covering the BBSHD across every brand that fits one agree — the BBS family is cadence-sensed, and torque sensing is an aftermarket modification, never a factory option.

What that means in the saddle. A cadence system reads whether you are pedalling, not how hard. Assist arrives at the level you selected shortly after the cranks start turning, and it holds there until you stop. A torque system reads your effort and scales with it, which feels more like a strong pair of legs than a switch.

Neither is better in the abstract; they suit different jobs. For grinding a loaded bike up a fire road in a low gear, a cadence system delivering a chosen, constant level is predictable and easy to manage.

For a trail bike where you want power to breathe with the terrain, torque sensing is the one to want. The SPECTER-S 3.0 is Eunorau's trail machine and uses one, which is why our review of it reaches a different verdict about a different rider.

The gear sensor is the other half of the story and it is a genuine plus. It briefly cuts power as you shift, which is what protects a 160 N·m drivetrain from having its chain and cassette destroyed by shifting under full load.

Charging, against the charger in the box

Eunorau publishes a charging time of "4 - 6 hours" and specifies the charger in the box as a "US standard 2.0 A smart charger". Those two figures can be checked against each other, and Eunorau supplies the missing constant on its own charger listing: an output voltage of 54.6 V.

At 2.0 amps and 54.6 volts the charger delivers 109.2 watts. Refilling 1,200 watt-hours at 109.2 watts takes 11.0 hours, and that is a floor — it assumes perfect efficiency and no constant-voltage taper at the end, neither of which happens.

Run it the other way and the published window needs a much bigger charger: a six-hour refill of 1,200 Wh requires 3.7 amps, and a four-hour refill requires 5.5 amps.

The explanation is the same generational change that runs through this whole page. Take the old 748.8 Wh pack and Eunorau's own 3 A fast charger at 163.8 watts, and you get 4.6 hours — squarely inside the published "4–6 hours". The published window describes the smaller pack; the bike now carries a much bigger one, and a bigger tank takes longer to fill.

So the practical guidance is a choice rather than a fault:

• On the charger in the box, charge overnight. Plug it in when you get home and it is full in the morning. For a bike used on weekends and hunts, this is a non-issue.
• If you need two long rides in one day, the 48V 3 A fast charger is $69 and brings a full refill down to about 7.3 hours. We can quote you one with the bike.
• If range is the real problem, Eunorau sells the 48V 25 Ah pack as a spare at $699, and lists the FAT-HD 1.0 Pro among the compatible models. A second charged pack beats a faster charger on a hunt.

What it costs against the bikes the engines pick

Ask an AI engine for the best hunting e-bike and it returns the same short list, with one claim worth checking:

"The Rambo Rebel 2.0 is the least expensive way into a genuine 1000W mid drive hunting bike, and features the BBSHD motor, which is the most field-proven in this class."

That is a checkable statement. We read both alternatives at the makers' own storefronts on 6 September 2026.

The "least expensive way in" costs $1,631 more than a bike running the same Bafang mid-drive family, with 480 fewer watt-hours and 75 lb less rated capacity. The engine also priced the Apex XD at "$6,350–7,000" when QuietKat's own listing reads $3,799.

The LED headlight and the RST Guide fork. Lighting is standard fitment here, which is not true of every bike in this comparison.

Two honest notes on that table. The Rebel publishes a higher top speed, 32 mph against 20, and that is reported as it stands — though at 1,000 W both bikes sit outside the same 44 definitions, and the higher figure adds a speed ground rather than removing the wattage one. And the Apex XD's 200 N·m is more torque than this bike's 160.

Rambo and QuietKat are named here for comparison and are not bikes we sell or recommend. The figures are their own published specifications.

If you want the same motor architecture with suspension at both ends, that is the FAT-HS at $3,449, and our FAT-HS review sets out what the extra money buys. If you want the newer generation of this exact bike, the FAT-HD 2.0 is $2,399 and we reviewed it here.

Why buy it here

Four things come with the bike from us, and they are the reason the same machine is worth more on this page than on a marketplace listing.

• Free shipping in the contiguous US, on a 78.7 lb bike in a 156 cm box. That is a real number on a freight item this size.
• Price-matched to Eunorau's own US price. You are not paying a retailer premium over the maker's storefront; if the maker's price moves, tell us.
• We file the warranty claim. You email us, we make the claim, we chase the part, we ship it. You never open a ticket with a manufacturer.
• Shop Pay instalments at checkout, and a US phone and inbox behind the order.

We also do one thing before you order that nobody else will: tell us the state you ride in and your inseam, and we will read you your state's own e-bike definition and check it against the 30.3 in standover before the bike ships.

The Mercer fit test

The Mercers are our editorial cast — a fixed family we hold every bike against, so fit gets measured the same way every time. Meet the Mercers. Every verdict in this table is computed from a published number — Eunorau's rider-height range, its standover, its saddle height, its weight and its payload — against age law where the rider is a minor.

The numbers doing the work: a rider-height range of 5'7" to 6'4", a 30.3 in standover, a saddle that sets between 33.9 in and 42.5 in off the ground, a 78.7 lb weight, a 375 lb payload, 1,000 W and 20 mph.

The pattern in that table is a height floor doing more work than usual. Three of the seven are excluded not by the law, the weight or the price but by a published minimum of 5'7" — unusually high, and a direct consequence of a 30.3 in standover on a big-wheeled fat frame. If you are near it, the standover measurement matters more than the height range, and we will check yours against it.

Has it been recalled?

No federal recall names Eunorau, and this is what we did to establish that.

We queried the CPSC recall database through three separate fields, each tested first with a control term to confirm the field actually filters. All three returned no record naming Eunorau. We then read all 19 federal electric-bicycle recalls individually and searched them for the brand as a whole word: none names it.

The instrument was validated in the other direction too, because a search tool that returns nothing for everybody would produce this same silence. Running the same screen for Specialized returns 54 records — so the tool convicts when there is something to convict on.

One limit, stated rather than glossed. CPSC product safety warnings are a separate instrument from recalls, and the warnings search is client-rendered — it returns nothing for any brand through an automated fetch, including brands we know carry open warnings. We could not screen the warnings database, and we are not reporting that as a clean result. What we can say is that the recall database, checked four ways, does not name Eunorau as of 6 September 2026.

Is it UL certified?

Yes — Eunorau publishes this model as UL certified, on the specification grid of its own product page, read 6 September 2026.

Two standards are the ones that get asked for in the US, and it is worth knowing which is which before you ask. UL 2849 covers the complete electrical system of an e-bike — battery, charger, motor and controller together. UL 2271 covers the battery pack on its own.

The practical step takes one email. A growing number of US apartment buildings, insurers and city fire codes now ask for a named standard, and some ask for a certificate number, before an e-bike may be charged or stored indoors. If yours is one of them, ask us for the certificate before you order and we will request it from Eunorau for you. Getting that in hand first is the difference between a bike you can charge where you live and a conversation with a building manager afterwards.

If your building has already told you it needs a specific number on paper today, the Freesky Wild Cat Ultra A-340 is the machine in our range whose UL 2849 and UL 2271 certificates we have opened and read ourselves.

The warranty, and who files the claim

On a mid-drive the drivetrain is the part that wears, and none of it is covered — chains, cassettes and chainrings are wear items on either policy. The Eunorau brand profile lists the full exclusion set alongside the terms.

Eunorau's warranty terms sit on its own warranty page, read on 6 September 2026.

The part specific to buying from us is simpler than the terms. You do not deal with the manufacturer. If something fails in warranty, you email us, we make the claim, we chase the part, and we ship it to you. Buying from a US retailer rather than a marketplace listing is what makes that possible.

Two practical points, on top of Eunorau's own terms. Keep the box for the first month, because shipping damage is the failure mode that turns up most on a 78.7 lb machine and it is easiest to resolve while everything is still packable. And register the bike's serial number with us at delivery, so a claim later does not start with a search for it.

Buying it from us

The Camo finish is a $100 option and nothing else changes with it — same motor, same battery, same brakes, same geometry.

The honest ledger

Green flags

• 1,200 watt-hours at $1,999. More battery than either bike the AI engines recommend instead, both of which cost over $3,600.
• 375 lb of published payload, the highest of the three machines compared on this page.
• A genuine Bafang mid-drive at 160 N·m, with a gear sensor that protects the drivetrain when you shift under load.
• Hydraulic brakes front and rear, 180 mm and 160 mm, with motor cut-off at the lever — the fix for the one complaint in the 2019 test.
• Rack, fenders, lights and kickstand fitted as standard, with none of it sold back to you as an accessory.
• A published geometry table, which is still not universal at this price and is what makes the fit section above possible.
• Serviceable, common parts — Bafang, Shimano, Kenda, RST, PROMAX — so a replacement is a search, never a special order.
• A spare 25 Ah pack exists and lists this model as compatible, at $699.

Red flags — where it is the wrong bike

• Wrong bike for public-road commuting. At 1,000 W it is outside the e-bike definition in 44 of 51 jurisdictions. If your riding is streets and bike paths, read our FLASH LITE ST review instead — 750 W, 20 mph, built for that job.
• Wrong bike for singletrack. A 100 mm fork and no rear suspension. Riders wanting a trail machine should look at the SPECTER-S 3.0 and its torque-sensing motor.
• Wrong bike for riders under 5'7". Eunorau's published height floor excludes three of our seven cast members outright.
• Wrong bike if you need a full charge in an afternoon. Eleven hours on the included charger. Plan overnight, or budget $69 for the faster one.
• Wrong bike if you want assist that reads your effort. Cadence sensing is a platform characteristic of the BBSHD family, and some riders stepping up from a torque-sensed commuter will notice it immediately.
• Wrong bike if you need a certificate number on paper today. The UL line is published without a standard or a number; ask us to obtain it before ordering if your building requires one.

Who should buy it

Buy it if your riding happens on private land, forest roads or your own acreage; if you carry weight and want capacity rather than speed; if you would rather have 1,200 watt-hours than a badge; and if you are between 5'7" and 6'4" with the standover to match. On those terms there is nothing at $1,999 that competes with it on battery and payload together.

Buy something else if you are commuting on public roads — take the FLASH LITE ST at 750 W. If you want suspension at both ends for rough ground, take the FAT-HS. If you want the newer generation of this same platform, take the FAT-HD 2.0. If you are under 5'7", none of these three fat frames is the answer and you should talk to us before ordering anything.

Before you buy: the checklist

1. Read your own state's definition at its own publisher, never a blog's summary of it. Four jurisdictions treat this as a bicycle; 44 do not.
2. If you are in a moped state, find out what registration and licensing involve there before ordering.
3. Measure your inseam against the 30.3 in standover. Height is the published filter; standover is the one that decides.
4. Decide where it charges, and check whether that building requires a certification standard on paper.
5. Plan the charge overnight, or add the $69 fast charger at checkout.
6. Work out your real load — rider plus gear — and hold it against 375 lb, or 296 lb on the conservative reading.
7. Confirm the color you want is in stock, since Gray and Camo are $100 apart.
8. Keep the shipping box for a month.

Limitations of this review

1. Every performance figure on this page is Eunorau's published claim, or arithmetic over its published figures. Range, top speed and payload are the maker's ratings, confirmed at its own product page on 6 September 2026 and recomputed here; none is an instrumented measurement, and the page never presents one as such.
2. Most specifications for this model have a single publisher, and it is Eunorau. Where a figure appears with no second source, that is the state of the published record. The figures we could corroborate independently — the price, the 2019 generation, every statutory position and the recall screen — carry their second source in the citation ledger.
3. The CPSC warnings database could not be screened. Its search is client-rendered and returns nothing to an automated fetch for any brand. The recall result above is a screened recall record and stops there.
4. The UL position is the manufacturer's published claim. We have not seen a certificate or a file number for this model. It is recorded as a claim, and 13 of 13 Eunorau bikes we checked on 6 September 2026 publish the same line the same way.
5. The 2019 comparison draws on one published test. Electric Bike Review is the editorial source of record for this model, and its figures were read from its own labelled specification fields. One further source referenced by retailers, electrifiedreviews.com, did not resolve from our machine on 6 September 2026; that is recorded as a failed retrieval, never as an absence of coverage.
6. "Total payload capacity" is not defined by Eunorau. We give both readings and use the conservative one where it changes an answer.
7. The unlocking discussion is based on the manufacturer's published description. We did not perform the procedure. We have not unlocked this model and do not publish instructions for doing so.
8. No search volume appears on this page because our keyword instrument is unavailable. Demand itself was measured. Demand was measured by harvest and by an AI panel; volume was not priced.
9. The AI panel ran on one accessible instrument. ChatGPT, Perplexity and Google AI Overviews were not run and are named here rather than implied.
10. Hawaii returned no verdict. Its statute could not be read at its publisher when the rule table was built, so it is reported as unread rather than counted either way.

What would age this page. Every figure here carries its retrieval date of 6 September 2026, and four named events would age it. Eunorau revises this product page in place, so a change to the battery, the speed setting or the payload on that page supersedes our specification table. Our own price and stock move. North Carolina moves to a three-class system on 1 December 2026, which changes one row of the jurisdiction screen even though it carries the same 750 W cap. And any first independent test of the current machine would supersede the 2019 comparison that this page is built around. We re-screen the recall database and re-run the jurisdiction table on every republish.

Frequently asked questions

How fast does the Eunorau FAT-HD 1.0 Pro go?

Eunorau publishes a maximum speed of 20 MPH and describes the bike as Class 2, speed limited, with the limit unlockable. The 2019 review still circulating online reports 28 mph, because that was the specification of the machine tested seven model years ago.

Is a 1,000 W electric bike street legal?

In most of the United States it is not an electric bicycle. Screened against all 51 US e-bike definitions against the federal 750 W ceiling, a 1,000 W machine qualifies in four jurisdictions — DC, Montana, Oregon and Rhode Island — and sits outside the definition in 44. Outside the definition does not mean unlawful: several states classify it as a moped, which brings registration and licensing rules instead.

Which states allow 1,000 W e-bikes?

Of the six states widely listed online as allowing 1,000 W, only Oregon does. Georgia, Kansas, Minnesota, Oklahoma and Virginia each cap their e-bike definition at 750 watts, read at their own publishers on 6 September 2026. Rhode Island is not usually on those lists but sets its ceiling at 1,492 watts, so it qualifies too.

How far will the FAT-HD 1.0 Pro actually go on one charge?

Eunorau claims up to 60 miles, which requires 20 watt-hours per mile from the 1,200 Wh pack. For the loaded, off-road riding this bike is sold for, plan on 34 to 48 miles depending on ground, load and how much you use the throttle.

How big is the battery on the FAT-HD 1.0 Pro?

48 V and 25 Ah, which is 1,200 watt-hours. Older reviews and some retailer listings still show 15.6 Ah, or 748.8 Wh, which was the earlier pack.

How long does the FAT-HD 1.0 Pro take to charge?

About 11 hours from empty on the 2.0 A charger supplied in the box. Eunorau's published figure of 4–6 hours corresponds to the older, smaller battery. Eunorau's 3 A fast charger, $69, brings a full refill to roughly 7.3 hours.

Does the FAT-HD 1.0 Pro have a torque sensor?

No. It uses cadence sensing with five assist levels, plus a Bafang BBSHD gear sensor that cuts power briefly as you shift. Cadence sensing is characteristic of the whole Bafang BBS motor family, whichever brand fits one.

How much weight can the FAT-HD 1.0 Pro carry?

Eunorau publishes a 375 lb total payload capacity. The bike itself weighs 78.7 lb. Eunorau does not state whether the 375 lb figure includes the machine, so the conservative reading leaves 296.3 lb for rider and gear.

How tall do you need to be to ride the FAT-HD 1.0 Pro?

Eunorau's recommended rider height is 5'7" to 6'4", and the standover is 30.3 in. If you are near the lower end, measure your inseam against the standover instead of relying on the height range.

What is the Hunter X7?

It is Eunorau's alternative name for this same bike. The product page is titled "FAT-HD 1.0 Pro / Hunter X7", and the two names describe one machine.

Is the Eunorau FAT-HD 1.0 Pro UL certified?

Yes. Eunorau publishes this model as UL certified on its own specification grid. If your building, insurer or city code needs the certificate itself, ask us before you order and we will request it from Eunorau for you.

Has the Eunorau FAT-HD 1.0 Pro been recalled?

No federal recall names Eunorau. We queried the CPSC recall database through three fields that we first confirmed actually filter, and read all 19 federal electric-bicycle recalls individually. CPSC warnings are a separate database whose search could not be read automatically, so that half is unscreened rather than clear.

What is the difference between the FAT-HD 1.0 Pro and the FAT-HD 2.0?

The 2.0 is the newer generation at $2,399, and our FAT-HD 2.0 review covers it. The 1.0 Pro is $1,999 and carries the larger 25 Ah battery discussed on this page.

Does it come with a rack and fenders?

Yes. A rear rack, full fenders, an LED headlight, a tail light and a kickstand are all standard fitment, and they appear in Eunorau's own product photographs.

Can I ride it on public trails and bike paths?

That depends on your state's definition and on the trail's own rules, which sit on top of it. In the 44 jurisdictions where 1,000 W falls outside the e-bike definition, a bike path that permits electric bicycles is not automatically permitting this one. Check both before you ride.

The bottom line

At $1,999 this is the most battery and the most payload we can find on a genuine 1,000 W mid-drive, and it undercuts the two bikes the AI engines recommend instead by more than $1,600 while carrying more of both. The 2019 review that still dominates the search results describes a machine with 40% less battery, and every criticism it made has since been designed out.

The catch is not the bike, it is the map. A 1,000 W motor is outside the e-bike definition in 44 of 51 US jurisdictions, which makes this a machine for private land, forest roads and the states that qualify. Buy it for that and it is exceptional value. Buy it to commute on and the law will be the problem, and the bike will not.

If it does suit you, the Gray is $1,999 in the cart and the Camo is $2,099, both shipping free in the lower 48 with the warranty claim handled by us.

If that map does not suit you, the FLASH LITE ST is our 750 W answer to the same question, and the full review index has the rest of the range with the same arithmetic applied.
