Eunorau Defender Review 2026: 66 lb, Two Suspensions

48V 500W rear hub · 60 N·m · 720 Wh · 20 MPH · 66 lb · 300 lb payload · 27.5" × 3.0" · $1,599 · verified September 11, 2026

Quick Answer — The Eunorau Defender is the lightest full-suspension e-bike on our shelf whose weight is published: 66 pounds, with a 100 mm ZOOM fork and a 165 mm EXA rear shock, on a 27.5 × 3.0 plus tire, at $1,599. If the weight of a dual-suspension e-bike is what has stopped you before, that is the whole pitch.

Two things decide this purchase and neither is on the headline spec sheet: Eunorau's biggest second battery fits only one of the two frame sizes, and the rack and fenders are a separate kit. Read both before you pick a size.

Every figure here is Eunorau's own published specification, verified at the manufacturer and recomputed.

How we verified this Eunorau Defender review

Verification basis: every specification on this page was confirmed at the manufacturer and recomputed. Eunorau's rendered product page and its storefront product feed were retrieved on September 11, 2026 and compared row by row against copies taken on September 8 and September 10. All three agree on every figure quoted here.

Every value on this page was read with its own label still attached, so no figure here comes from a neighbouring row.

Eunorau publishes two range figures — 40 miles on the standard pack and up to 80 with two — and they are read from two different surfaces of the maker's own page. Every rate, quotient and headroom figure here is division, and the division is written out where it happens.

Price, colorways and stock come from our own store listing through the Shopify Admin API on 10 September 2026, and every cart link on this page was confirmed to resolve.

The legality screen reads each state's own statutory definition from a 51-row dataset carrying one citation per jurisdiction.

The recall search ran against the Consumer Product Safety Commission's own listings through four routes, each one first proved on a brand that does carry a recall.

Search for "Eunorau Defender" and you get a different bike

There is an older, bigger machine called the Defender S, and it owns the search results for this bike's name.

Ask a search engine about the Defender today and it answers about the Defender S. On the first query we ran, seven of the eight results described that bike instead — a 2021 Electrek review, an Electric Bike Report review, a BikeRide page, Eunorau's own newsroom and three retailer listings. The generated answer described a 1,500-watt dual-motor bike from beginning to end. It never reached the 500-watt bike at all.

They are different machines. The Defender S is a dual-motor, all-wheel-drive fat-tire bike. This one is a single 500-watt rear hub on a 3.0-inch plus tire, and it is the lighter and cheaper of the two.

Four published range figures appear for this bike, and each is stated for a different battery configuration. Eunorau publishes 40 miles on the standard pack and up to 80 miles with two. One retailer publishes 110 miles, stating it for a 48V 17Ah pack plus a second 17Ah pack. Another publishes "60+ miles". All three are published figures; they describe different battery configurations, and the #range section below works through what each one is counting.

The speed figure also splits by country. One engine answer put this bike at "15.5 MPH / 25 KPH", drawing on an overseas listing where 25 km/h is the statutory limit. Eunorau's US page publishes 20 MPH (32 KM/H), speed limited and unlockable, and prints Class 2. The US figure is the one this page screens against.

Sixty-six pounds is the headline

Eunorau publishes 66 lbs, and on a bike carrying a shock at both ends that is the specification worth leading with. A fork and a rear shock both add weight, so a dual-suspension frame starts its life heavier than a hardtail of the same size.

Where you feel it. Lifting it onto a car rack. Getting it up a step. Turning it around in a hallway. Picking it up off the ground on a trail. Each of those is a different experience at 66 pounds.

Where it comes from. A 3.0-inch tire instead of a 4.0-inch one, a single rear hub instead of two, and a 720 Wh pack instead of a larger one. The Defender's weight is the sum of three deliberate design choices, and each one buys the weight with something else.

What it leaves you to carry. Eunorau publishes a 300 lb total payload capacity. Subtract the bike's own 66 and 234 pounds remain for rider, clothing, pack and anything on the bars — our subtraction from the two published figures.

Both figures on this chart are Eunorau's published numbers. The 234 pounds in the middle is the subtraction between them.

The battery note that decides your frame size

Eunorau sells the Defender in a 17-inch and a 19-inch frame, and offers the second battery in 15 Ah or 17 Ah. Inside the maker's own specification table is a note that decides which of those combine:

The second 17ah battery is not compatible with 17" DEFENDER; To utilize the 17Ah second battery on the 19" DEFENDER, it's necessary to lock out the rear shock.

That note has two limbs, and both are worth reading twice.

1. The 17 Ah second battery fits the 19-inch frame. On the 17-inch frame, the second-battery option is the 15 Ah pack.
2. Running the 17 Ah second battery on the 19-inch frame means locking out the rear shock. The largest-capacity configuration and the working rear suspension are separate settings.

What to do about it. If rear suspension is the reason you are buying this bike, the 15 Ah second battery is the pack to fit: two 15 Ah packs is 1,440 Wh, which is Eunorau's own 80-mile configuration, and it leaves the shock working. If distance matters more than the rear shock on long days, the 19-inch frame with the 17 Ah pack is the configuration that gets there.

And if you are between frame sizes, this note is the tie-breaker. Eunorau publishes a recommended rider height of 5'3" ~ 6'4" across both frames, so a rider in the middle of that range can take either — and the 19-inch keeps every battery option open.

Every cell on this matrix is read from the compatibility note quoted above, on Eunorau's own specification table.

Three inches is not four: what the tire actually is

Eunorau publishes CHAOYANG 27.5 × 3.0 tires. That is a plus size. A 4.0-inch fat tire is a genuinely different tool — a third more casing width — and the two behave differently enough that the choice should be made on your ground, not on the word in a product title.

A published comparison of the two widths puts it in plain terms. Wildeway's side-by-side writes that the 3.0" tire "handles much sharper", that "because there is less rotating mass" it feels nimble, and that "less friction means your motor doesn't have to work as hard". It calls the 3.0 — "often called a 'Plus' tire" — "the Goldilocks of the e-bike world".

And a rider who tried both says the same thing from the saddle. On the Electric Bike Review forums, one rider reports: "I tried a fat tire (4-inch) e-mountain bike at a dealer and did not like its sluggishness". One rider's experience rather than a measurement — and the experience the specification predicts.

Which one you want depends entirely on your ground. For pavement, gravel, hardpack, fire roads and rooty singletrack, a 3.0-inch plus tire is the better tool and the lighter one. For soft sand, deep snow or a beach, the 4.0 is what floats, and the FAT-HD 1.0 Pro is the bike to read next.

Buy it on the maker's number: CHAOYANG 27.5" × 3.0". If your ground needs a 4.0-inch casing, this is not the bike and the FAT-HD 1.0 Pro is.

Casing widths drawn to the published dimensions. The plus tire is the lighter tool; the fat tire is the one that floats.

Where you may ride it: 51 jurisdictions, screened

Five hundred watts sits two hundred and fifty under the line the federal definition draws. That margin is why the legal question on this bike is a short one, and it is worth settling before anything else.

15 U.S.C. § 2085(b) defines a low-speed electric bicycle, in the statute's own words, as "a two- or three-wheeled vehicle with fully operable pedals and an electric motor of less than 750 watts (1 h.p.), whose maximum speed on a paved level surface, when powered solely by such a motor while ridden by an operator who weighs 170 pounds, is less than 20 mph."

16 CFR § 1512.2(a)(2) carries the same wording into the Consumer Product Safety Commission's bicycle regulations.

The speed limb is worth reading closely. The statute says "less than 20 mph" and Eunorau publishes 20 MPH, so the bike sits on that line rather than under it — how the Commission reads a figure sitting on the boundary is not something a specification answers. The state definitions below are written differently, in "20 miles per hour or less" form, and the bike sits inside every one of them.

On the wattage limb there is no such question. The motor is 500 watts, which sits 250 watts under the federal ceiling. That is far enough below it that the boundary question — whether a state's cap includes a motor of exactly 750 watts, which splits the states almost evenly — never reaches this bike.

On the throttle limb, Eunorau publishes 20 MPH (32 KM/H), speed limited and unlockable, and prints CLASS Class 2 in the specification header, with a thumb throttle fitted.

We screened those published figures against all 51 US jurisdictions, reading each state's own statutory definition and its own published caps:

Zero jurisdictions place these published figures outside their definition. Hawaii reaches that result whichever way its definition is read — the federal cross-reference in its own code and the 750-watt cap both leave a 500-watt motor inside — and our Hawaii page works through the 2026 amendments section by section.

Two states ask for a step before your first ride, and neither is about this bike's specification. Hawaii requires a one-time $30 county registration, and New Jersey requires registration and a licensed rider. Everywhere else the published figures are the whole of the answer. Our state e-bike law pages carry each one.

Alaska and Kentucky are a different situation from a refusal. Neither publishes an electric-bicycle definition, so a bike there is classified under whatever vehicle category the rest of that state's code reaches. Our state e-bike law pages work through the statutes jurisdiction by jurisdiction.

One setting is yours to control, and Eunorau publishes both ends of it. The specification header reads "Speed limited: Unlockable", and the maker's own copy states that "Riders can UNLOCK the speed limit on the display for off-road use to reach 28 miles per hour."

Left where it ships, the bike is Class 2 everywhere on the table above. At 28 MPH it is a Class 3 machine by the model-legislation definition, which in most states that use the framework carries a helmet requirement, a minimum age and no access to some shared paths.

That is where a ticket comes from, and it is the only real risk this bike carries. A Class 3 machine on a path posted for Class 1 and 2 is a citation in most three-class states, and the officer reads the label and the setting, not the receipt. Leaving the limiter where Eunorau sets it keeps you inside the screen above in all 49 jurisdictions that publish a definition.

In Hawaii the penalty attaches to the paperwork rather than the speed. Riding an unregistered e-bike on a roadway, bicycle lane, path or sidewalk there is an infraction, and enforcement runs to citation or impoundment; the registration is a one-time $30 at the county finance office. New Jersey asks for registration and a licensed rider. Your state's own page carries the rules that apply at each speed.

Each of the 51 rows behind this chart carries its own statutory citation. The screen reads the state's published caps against the bike's published figures.

Range: what Eunorau publishes, and what the arithmetic gives

The pack is 48V 15Ah, which is 720 watt-hours — our multiplication, and the figure every calculation below rests on.

Eunorau publishes two range numbers, and they agree with each other exactly. The product description gives "BATTERY RANGE: 40 Miles (48V/15Ah SAMSUNG)", and the specification header gives up to 80 miles with dual batteries.

Put each one over its own capacity and the same rate falls out twice. 720 Wh ÷ 40 miles is 18.0 watt-hours per mile. 1,440 Wh ÷ 80 miles is 18.0 watt-hours per mile. Two separately published claims, one rate — which is the most useful thing a pair of range figures can do, because it means the maker is dividing by the same number you would.

That rate is the maker's own claim turned into a number you can carry to any configuration on the list.

Where the other published figures come from. A retailer publishes 110 miles and states the configuration alongside it: a 48V 17Ah pack plus a second 17Ah pack, which is 1,632 Wh. A second retailer publishes "60+ miles".

Put those on the same rate and they separate cleanly. At 18.0 Wh per mile, 1,632 Wh covers about 91 miles, so the 110-mile figure implies roughly 14.8 Wh per mile instead. Each number is published by the party that states it, and each describes a different pack and a different set of riding assumptions.

There is a published number here that is not a specification. Eunorau's own product page carries 163 customer reviews, 148 of them at five stars, read on 11 September 2026. It is the maker's own widget on the maker's own store, so read it as that — but it is a larger sample than any single review, including this one.

What actually moves your range, whichever number you start from: rider and cargo weight against the 300 lb capacity, how much of the ride is climbing, tire pressure, air temperature, wind, and which assist level you leave it in. A throttle-only mile costs more than a pedal-assisted one on every electric bike ever built.

Both the 40-mile and the 80-mile bars are Eunorau's own published figures. They divide to the same rate.

Your warranty, and the three things to do in week one

Eunorau publishes two warranty documents, and both were live on 11 September 2026 — the 24-Month+ Limited Warranty and the Warranty Policy. Both are set out below.

The first document states: "Eunorau electric bicycle frames are covered by a 10-Year replacement/repair Warranty for the original purchaser." The second states: "EUNORAU ebike frames are covered by a replacement warranty for 5 years base on frame production date." Both sentences are quoted from the pages linked above, retrieved the same day.

What this means for you, practically. Our listing quotes the 24-Month+ document, and that is the document we administer a claim under. Three things are inside your control, and all three are worth doing in the first week:

1. Register the bike with Eunorau after delivery. The 24-Month+ document asks for it; the Warranty Policy states registration happens automatically when the original purchaser orders online. Doing it yourself costs nothing and removes the question.
2. Keep your Redtail order confirmation. It is the proof of purchase, and the warranty runs to the original purchaser.
3. Send the claim to us, not to the manufacturer. We coordinate it from here: support@redtailebikes.com.

One line in both documents is worth knowing before you ride. The frame warranty covers the frame: the 24-Month+ document lists suspension parts outside it, and the Warranty Policy puts the rear shock and fork in its 12-month component tier, alongside the motor, display, controller and charger. On a bike bought for its suspension that is the term to have in mind, and it is the same term every full-suspension e-bike is sold under.

Our return window is ours and does not vary. Change-of-mind returns are accepted on unopened, factory-sealed items requested within 72 hours of delivery, with a 15% restocking fee plus return shipping. That is Redtail's own policy, separate from anything above.

Suspension, brakes and the parts your hands are on

The Army Green frame from the drive side. The rear shock sits in front of the seat tube; the fork is the black ZOOM unit at the head tube.

Four of those deserve a sentence.

The rear shock is the whole point. A 165 mm EXA unit behind a 100 mm fork is a genuine dual-suspension layout, and at $1,599 that pairing is uncommon enough to be the reason this bike is on our shelf.

The brakes are properly specified for the load. Hydraulic discs at 180 mm front and rear, with a motor cut-off switch in the levers, is the right hardware for a machine carrying up to 300 pounds down a hill. The cut-off means the motor stops driving the moment you reach for a lever.

The drivetrain is a 7-speed with the motor carrying the climbs. A SHIMANO ALTUS ARDM310DL derailleur and an ASLM315 shifter on a 14–28T cassette, with the hub's 60 N·m doing the work a wider gear range would otherwise do.

On a long loose climb where you want a lower gear to spin, the range is what it is. If your climbs are long and loaded, the FAT-HD 2.0 puts a Bafang mid-drive through the gears instead.

The Safari frame from behind. The drive is a single rear hub, both rotors are 180 mm, and the casing is the CHAOYANG 27.5 × 3.0.

The controller has headroom above the nominal figure. 48V × 20A is 960 watts of peak electrical draw against a 500-watt nominal rating — our multiplication. The federal and state definitions are written on the motor's rated output, which is the 500 watts Eunorau publishes.

The rack-and-fender kit, and when to add it

Eunorau sells the rack and fenders as a kit, alongside a second battery and a choice of saddle. The bike arrives as a trail bike.

Eunorau makes a matched rack-and-fender kit for this frame. Add it if the bike is going to commute as well as ride trails: the fenders keep the spray off your back and the rack takes panniers. Both parts are built for this frame and both are one added line on the order.

It matters least if you are buying it to ride trails, which is what the 165 mm shock and the plus tire are for. On that use the kit is optional in the ordinary sense of the word.

Budget for the kit if your answer is "both". The Defender is genuinely capable as a rough-road commuter, and that is the configuration that wants the two parts the box does not include. Tell us at checkout and we will price them onto the same order so there is no second invoice and no second shipping charge.

Charging, and the overnight habit this bike wants

Eunorau publishes a charging time of "4 - 6 hours", and ships a US standard 2.0 A smart charger. Those two figures are worth holding together. At 48 volts a 2.0 A charger is about 96 watts, and 720 Wh at 96 W is 7.5 hours from empty before charging losses — our division.

So plan somewhere in the four-to-seven-and-a-half-hour band, depending on how deep you ran the 720 Wh pack down and how warm the battery is. Either number makes this an overnight bike.

Seven and a half hours means you start it after dinner and it is done before you are awake. What it will not do is refill between a morning ride and an afternoon one — that is the job the second pack exists for.

A second pack is a second 7.5-hour charge. Run both overnight on the one charger and it costs you nothing; run them in sequence during the day and it costs you the day.

How to charge it. CPSC publishes four rules for micromobility batteries, and two of them land squarely on a dual-battery bike: "Only use the charger provided with or recommended by the manufacturer of your micromobility device", and "Only use a replacement or secondary battery pack that has been tested and approved to work safely with your device." The second is the one to remember when you order the extra pack — buy Eunorau's, made for this frame.

And on timing, CPSC is blunt: "Always be present when charging micromobility products" and "Never charge them while sleeping or when you are not at home." On a 7.5-hour charge that is a real constraint, and it is the argument for starting it after dinner instead of at bedtime.

Where it sits on our own shelf

What the Defender wins on is the weight-to-suspension ratio. Nothing else we sell puts a fork, a rear shock and a 66-pound curb weight together at once, and that combination is the reason it exists.

What it asks in exchange is a 7-speed drivetrain and a rack-and-fender kit ordered alongside — which is how the price and the weight land where they do.

Buying it from us

What stands behind every figure above. Each one is Eunorau's published specification, verified at the manufacturer on 11 September 2026 and recomputed here, with the arithmetic shown wherever a number is ours.

Safari is the sand colorway, offered in the 19-inch frame. Army Green is offered in both sizes.

Every variant on our listing was confirmed buyable through the Shopify Admin API on 10 September 2026, and every cart link on this page was checked to resolve.

Why buy the Defender from us

Same bike, same price, and the part that differs is what happens after it arrives. Eunorau charges $1,599 on its own US store against a $1,899 list, and so do we — checked the same day. So the question is not price, it is who you call.

And the part nobody advertises: we will tell you not to buy it. Six of the seven riders in the fit test below clear the published range, and the one who does not gets pointed at a different bike rather than sold this one. Every "wrong bike" line on this page ends at a machine we also sell, because a returned bike helps neither of us.

The Mercer fit test

Seven riders, two frame sizes, and one published height range that spans thirteen inches. Every verdict below comes from a number Eunorau prints or a rule a state writes — the Mercers and Kowalskis are our fixed editorial cast, never testers.

Six of the seven riders fit, which is a wide window for a two-frame bike. A 5'3" to 6'4" recommendation spans thirteen inches, and two frame sizes are what buy that width.

The sharpest contrast on this table is Jack and Ivy, and it is not about ability. At 6'1" Jack takes the 19-inch frame and every battery Eunorau offers for it. At 12, Ivy sits below the published fit range, and the age rules for a throttle-equipped Class 2 machine settle her row before the tape measure does.

Same bike, same specification sheet, opposite answers — and the sheet on its own would have told you neither.

Two published ranges decide the fit, and a published geometry table settles the rest. Eunorau gives a recommended rider height of 5'3"–6'4" and a saddle height of 35.0"–40.9" from the ground, plus nine measured dimensions for each frame:

Eunorau prints each of those in millimetres alongside the inch figure. The inch column is the maker's own conversion.

What that table tells you that the height range does not. The two frames share their chain stay, bracket height and head tube to the millimetre — the difference between them is 51 mm of seat tube, 49 mm of stack and 25 mm of top tube. So the 19-inch is taller and longer in the body, and rides the same at the back. If you are between sizes, the trade is reach and standover — the handling geometry is identical.

Standover and head angle are the two figures Eunorau's geometry table does not carry, so if you are within an inch of the 5'3" floor, ask us for a standover measurement in writing before you order and we will get it for you.

Has it been recalled?

No federal recall record names Eunorau. We queried the Consumer Product Safety Commission's recall service on 10 September 2026 across four separate routes, each one first proved on a brand that does carry a recall, and read all 19 federal electric-bicycle recall records in the corpus. None names Eunorau as a whole word.

CPSC also runs a separate warnings index, and it is not part of this answer. It returned no rows on any query we ran, for any brand, so it tells you nothing about Eunorau either way. What this answer rests on is the four recall routes above, all of them clean.

Is it UL certified?

Yes. Eunorau prints "UL CERTIFIED: Yes" in this model's own specification header, alongside its motor, battery and class rows — a model-specific statement rather than a company-wide one.

Behind that row is a dated company statement naming both standards. Eunorau's newsroom, dated 5 March 2023, says "all of our ebikes have passed the UL 2849 testing" and "Our ebike batteries have also passed the UL 2271 tests"

Eunorau also publishes what the battery testing involved — thermal cycling, overcharge, impact, water immersion, vibration and UV exposure — and states that it sought both certifications voluntarily.

The two standards cover different things, and you want both. UL 2271 is the cell-and-pack standard, covering the battery's wiring, case materials and cells. UL 2849 is the system-level standard, covering battery, charger, motor and controller together as one electrical system. A pack can be safe on its own bench and still be charged by the wrong supply; 2849 is the standard that tests the whole loop.

Where that becomes a purchase condition. New York City's Local Law 39 of 2023 makes it unlawful to sell or lease an e-bike in the city unless it is certified "for compliance with Underwriters Laboratories (UL) standard 2849." If you are buying into New York City, ask us for this model's certificate in writing before you order and we will request it from Eunorau for you.

Everywhere else, treat certification as one layer and habit as the other: charge on a hard surface, away from your exit route, on the charger it shipped with, per CPSC's own guidance.

Green flags / Where it is the wrong bike

The left column is what Eunorau publishes and we verified. The right column is not a list of faults — it is a list of riders this bike does not suit, each one pointed at a machine on our shelf that suits them better.

Green flags

• 66 lb with a shock at both ends, published by Eunorau — the lowest of the 36 full-suspension bikes on our shelf whose weight our listings state, out of 61 we stock.
• A 165 mm EXA rear shock behind a 100 mm ZOOM fork, a real dual-suspension layout at $1,599.
• Hydraulic discs at 180 mm front and rear, with a motor cut-off switch in the levers.
• 720 Wh as shipped, with a second pack offered in 15 Ah and 17 Ah and a dual-battery design to take it.
• A thirteen-inch fit recommendation across two frames, 5'3" to 6'4", on a nine-row published geometry table.
• Class 2 as shipped, which sits inside every state definition we screened — 49 of the 49 that publish one.
• 300 lb total payload, leaving 234 lb for rider and cargo after the bike's own 66.
• "UL CERTIFIED: Yes" in this model's own specification header, published by Eunorau, backed by a dated 2023 statement naming UL 2849 and UL 2271.
• A 48V × 20A controller, which is 960 W of peak draw behind a 500 W nominal motor.

Who it is wrong for, and where to go instead

• Below 5'3" — the published fit range starts there; the META26 reaches lower and arrives with a rack fitted.
• On sand or deep snow a 3.0-inch casing floats less than a 4.0-inch one — the FAT-HD 1.0 Pro is built for that ground.
• For long loaded climbs where you want gears rather than watts — the FAT-HD 2.0 runs a Bafang mid-drive through the drivetrain.
• If you want a rack and fenders fitted out of the box, the META26 arrives equipped and costs less.
• If you want the 17 Ah pack and the 17-inch frame together, the published note puts those on different frames — take the 19-inch.
• If you want maximum capacity and a working rear shock at once, the 15 Ah second pack is the configuration that does both.
• If you need a midday top-up rather than an overnight charge, a second battery answers it better than the charger does.
• If you need a step-through frame, the Max-Cargo is the low-standover bike on our shelf.

Buy it if / Buy something else if

Buy it if you are between 5'3" and 6'4", you want genuine dual suspension without crossing $2,000, and the weight of a full-suspension e-bike is the thing that has stopped you before. Sixty-six pounds is the reason this bike exists, and it is the number to buy it on.

Buy something else if your ground is sand or deep snow — the FAT-HD 1.0 Pro runs the 4.0-inch casing that floats on it. If your climbs are long and loaded, the FAT-HD 2.0 puts a mid-drive through the gears. If you mostly ride pavement and want the rack and fenders fitted, the META26 is the cheaper and better-equipped answer.

Buy the 19-inch specifically if the largest second battery is in your plan, because the published note puts the 17 Ah pack on that frame.

Three questions, in this order. Height narrows the frame, the battery note decides it, and your ground decides whether this is the bike at all.

Before you buy: the checklist

Ten things to settle before you order, in the order they matter. The first three decide which bike and which frame; the rest decide what arrives with it and how you live with it.

1. Measure against 5'3"–6'4", the published recommended rider height.
2. Pick the frame on the battery note, not only on height, if you land in the middle of that range.
3. Decide whether you want the 17 Ah pack — it belongs to the 19-inch frame and asks for the shock locked out.
4. Budget for the rack-and-fender kit if this is going to commute as well as ride trails.
5. Check your ground: 3.0-inch plus for hardpack, gravel and trails; 4.0-inch fat for sand and snow.
6. Plan on 18 Wh per mile, the rate Eunorau's own 80-mile dual-battery figure implies.
7. Plan on an overnight charge — Eunorau publishes 4–6 hours, and the supplied 2.0 A charger works out to 7.5 hours from fully empty.
8. Check your car rack's per-bike limit against 66 lb before the bike arrives.
9. Register the frame with Eunorau in the first week and keep your order confirmation.
10. Leave the 20 MPH limit where it ships if you want the legal screen above to keep describing your bike.

Frequently asked questions

How much does the Eunorau Defender weigh?

66 lb, published by Eunorau. Total payload capacity is 300 lb, which leaves 234 lb for rider and cargo once the bike's own weight is subtracted.

Is the Eunorau Defender the same as the Defender S?

No. The Defender S is an older dual-motor, all-wheel-drive fat-tire bike on a 4.0-inch casing. This is a single 48V 500W rear hub on a 27.5 × 3.0 plus tire at $1,599, and Eunorau publishes 66 lb for it. Search results for "Eunorau Defender" return the Defender S first, so check the motor count and tire width on any page you read.

Does the Eunorau Defender have full suspension?

Yes — a ZOOM 100 mm travel fork up front and an EXA KS/A5 165 mm shock at the back, both to Eunorau's published specification.

How far does the Eunorau Defender go on one charge?

40 miles on the pack it ships with, published by Eunorau. Its second published figure, up to 80 miles, is for two batteries. Both work out to the same 18.0 watt-hours per mile.

Why do different listings say 60, 80 and 110 miles?

Because each figure counts a different battery. Eunorau's 80 miles is two packs; a retailer's 110 is two 17 Ah packs, which is 1,632 Wh; another's 60+ is one. Check the pack count before you compare.

How fast does the Eunorau Defender go?

20 MPH (32 km/h) as shipped, under Eunorau's speed limit setting, and the maker prints Class 2 in the specification header. Eunorau also publishes that the limit is unlockable on the display for off-road use, to 28 MPH — which is Class 3 territory and carries different rules in most states. Some listings quote 15.5 MPH / 25 km/h, which is the limit used outside the US.

Is the Eunorau Defender street legal?

Its published figures — 500 W and 20 MPH with a thumb throttle — sit inside the electric-bicycle definition of all 49 US jurisdictions that publish one, as Class 2. Alaska and Kentucky publish no e-bike definition, so a bike there falls under whatever category the rest of the state's code reaches.

What size Eunorau Defender should I buy?

Eunorau publishes a recommended rider height of 5'3" to 6'4" across a 17-inch and a 19-inch frame. If the 17 Ah second battery is in your plan, the 19-inch is the frame it belongs to.

Can I fit a second battery to the Eunorau Defender?

Yes, in 15 Ah or 17 Ah. Eunorau's published note states the 17 Ah pack is not compatible with the 17-inch frame, and that using it on the 19-inch requires locking out the rear shock. The 15 Ah second pack fits either frame and leaves the shock working.

Does the Eunorau Defender come with a rack and fenders?

No — Eunorau sells them as a kit for this frame, alongside the second battery and saddle options. Budget for the kit if you plan to commute on it, and we will price it onto the same order.

What tire size is on the Eunorau Defender?

CHAOYANG 27.5" × 3.0" — a plus size. A fat tire is 4.0 inches or wider, which is roughly a third more casing width and a different tool for sand and snow.

How long does the Eunorau Defender take to charge?

Eunorau publishes 4–6 hours. The supplied 48 V × 2.0 A charger is about 96 watts, so a fully empty 720 Wh pack works out to 7.5 hours by our division. Plan on the band between the two; either way it is an overnight bike.

What brakes does the Eunorau Defender have?

Hydraulic disc brakes with 180 mm rotors front and rear, and a motor cut-off switch in the levers so the motor stops driving as soon as you brake.

What gearing does the Eunorau Defender have?

A SHIMANO ALTUS ARDM310DL 7-speed rear derailleur with an ASLM315 shifter, on a 14–28T cassette, a 44T chainring and 170 mm forged alloy cranks. The hub motor's 60 N·m does the work a wider gear range would otherwise do.

Has the Eunorau Defender been recalled?

No federal recall record names Eunorau across four validated CPSC query routes searched on 10 September 2026. CPSC's separate warnings index returns nothing for any brand and is reported unscreened rather than counted.

Are Eunorau batteries UL certified?

Eunorau prints "UL CERTIFIED: Yes" in the Defender's own specification header, and publishes a dated statement from 5 March 2023 that all of its e-bikes have passed UL 2849 testing and its batteries have passed UL 2271 testing. UL 2271 covers the cells and pack; UL 2849 covers battery, charger, motor and controller as one system.

What warranty comes with the Eunorau Defender?

Eunorau publishes two warranty documents. Its 24-Month+ Limited Warranty states a 10-year frame warranty with 24 months on battery, motor and electrical components; its Warranty Policy page states 5 years on the frame, a 2-year prorated battery warranty and 12 months on major components. Register the bike on delivery, keep your order confirmation, and send any claim to us — we coordinate it.

Is Eunorau a good brand?

Eunorau publishes UL 2849 and UL 2271 testing across its range, and no federal recall record names it across four validated CPSC query routes searched on 10 September 2026. Our Eunorau brand profile covers all 31 models, the warranty and the parts support in full.

Limitations of this review

What this page rests on, and where the published record runs out. Each item below names a specific boundary of the evidence rather than a general caveat.

1. Every figure on this page is Eunorau's own published specification, verified at the manufacturer and recomputed here. The basis is specification verification, and the page says so wherever a number appears.
2. Eunorau publishes a nine-row geometry table for both frames, a recommended rider height and a saddle-height range. Standover height and head angle are the two fit figures it does not publish, and standover is the one a rider near the 5'3" floor most wants — ask us and we will measure it.
3. Both the 40-mile and the 80-mile figures are Eunorau's, published on two different surfaces of its own product page. The 80-mile figure needs a second pack, which is bought separately and is not part of the $1,599.
4. Two Eunorau warranty documents were live on 11 September 2026 with different frame, battery and component terms. Both are quoted and linked in full above so a buyer can read each one.
5. CPSC's warnings index could not be screened. It is client-rendered and returns nothing for brands with confirmable warnings, so its silence carries no information and it is excluded from the recall answer.
6. The UL statement is Eunorau's own. The model page prints "UL CERTIFIED: Yes" and the 2023 announcement names UL 2849 and UL 2271. A buyer in a jurisdiction that conditions sale on certification should request the certificate document for this model, and we will obtain it.
7. Range figures are manufacturer and retailer claims, recomputed here against published pack sizes. Real range varies with rider and cargo weight, terrain, tire pressure, temperature, wind and assist level.
8. Our product title and the maker's tire specification use different words for the tire. The measurement on this page is the maker's published 27.5" × 3.0".
9. The 51-jurisdiction screen reads the bike as Eunorau ships it — 500 W and 20 MPH under the speed limit. Eunorau publishes the limit as unlockable to 28 MPH; at that setting the screen above no longer describes the machine, and the Class 3 rules in your state do.

The bottom line

The Defender is the lightest way to buy two suspensions on our shelf — the lowest published full-suspension weight of the 61 we stock.

Sixty-six pounds, a 100 mm ZOOM fork, a 165 mm EXA rear shock, hydraulic brakes with 180 mm rotors at both ends and 720 Wh as it ships, at $1,599 with free shipping and a frame warranty we administer. If the weight of a full-suspension e-bike is what has stopped you before, this is the one that gets light enough to stop mattering.

Buy it on ground and on frame size. Plus tires for hardpack, gravel and trails; fat tires if your ground is sand or snow. And if the largest second battery is in your plan, take the 19-inch frame — that one published note decides more about this purchase than any performance figure on the sheet.

What you are actually choosing between is a bike that is easy to lift and gives you a working rear shock, and a heavier bike that floats on soft ground. The Defender is the first one, and at $1,599 you are not paying a premium to make that choice.
