Eunorau SPECTER-ST 2.0 Review 2026: Low Standover

1000 W · 160 N·m · 1,560 Wh in the box · 19.3 in standover · 88 lb · $2,999 · full suspension · verified August 29, 2026

Quick Answer — The Eunorau SPECTER-ST 2.0 is a $2,999 full-suspension step-through with a 1000 W Bafang M620 mid-drive, a torque sensor and a 19.3-inch standover. The second 48V 15Ah battery ships free with it, here and at Eunorau, as of 29 August 2026. It puts a serious climbing motor on a frame you can walk through. Two cautions: the spec table on Eunorau's own page belongs to its R1 line, and the "Class 3" label does not survive the statute.

Who the SPECTER-ST 2.0 is for

The frame is the point. That drop between the saddle and the head tube is a 19.3-inch standover on a bike with suspension at both ends.

Someone who wants to ride trails, gravel and hills, and who wants to get on the bike by stepping through it instead of swinging a leg over a top tube.

That combination is scarce. We screened our own live catalog (189 active e-bikes on 29 August 2026), and exactly two machines pair a step-through frame with full suspension and a mid-drive; this is the only one of them built as an eMTB. It is a 1000 W Bafang mid-drive with 160 N·m of torque on a frame with a 19.3-inch standover and suspension at both ends.

Skip it if lifting is part of your day (at a published 88 lb this bike lives at ground level), or if you need it to be unambiguously a class 3 e-bike in your state, for reasons set out below.

Both of the things this review keeps returning to are in this one frame: the front triangle drops away where a top tube would be, and a shock sits tucked behind the seat tube.

How we verified this review

What we did. We archived Eunorau's live SPECTER-ST 2.0 page on 29 August 2026 and read every published figure from that deposit copy, including the Components list and the A-to-L geometry table. We downloaded and opened all eleven images the page links, which is where the geometry figures are printed.

How we found the spec-table problem. Each machine's published specification is diffed against its own siblings' before anything is written. This page's 18-row specification block matched Eunorau's R1-17 page word for word, 17 rows in identical order, which is what sent us to the Components list below it. Both R1 pages were re-fetched and deposited on 29 August 2026.

How we checked the class claim. Eunorau prints "CLASS: Class 3". California Vehicle Code § 312.5 was read in full from the Internet Archive's capture of 24 August 2026, after the state's own server refused our connection on the 29th.

The second battery. Eunorau's live page includes the 48V 15Ah secondary battery as a free gift at $2,999, verified 29 August 2026, and our listing includes it on the same terms as of the same date.

What we computed. Pack energy, the watt-hours per mile implied by the range claim, and the range bands. We also screened our own live catalog (189 active e-bikes on 29 August 2026) for the step-through + full-suspension + mid-drive combination, and hand-checked every candidate the screen returned. Scripts and datasets saved and re-runnable.

What we did not do. We have not ridden it. No handling, comfort or climbing verdict of our own appears below.

On the recall check. The CPSC recall service returned errors on every route we tried, on 28 and again on 29 August 2026: the REST endpoint 404s, the search and newsroom pages 403, and the recalls RSS feed 404s. We therefore do not know this brand's recall status and do not claim it is clear. We will publish the result when the service is reachable.

Where a fact has only one publisher (a manufacturer's own specification, the text of a statute), our citation ledger marks it SOLE-PUBLISHER rather than inventing a second source; everything load-bearing that can be independently corroborated is.

Neutrality. Redtail sells this machine. The honest ledger carries what does not flatter it. Corrections: corrections@redtailebikes.com.

Eunorau SPECTER-ST 2.0 specifications

Read this table, not the one on the product page. Every figure below is from Eunorau's Components list and geometry table, retrieved 29 August 2026: the two blocks that describe this machine. The reason that distinction counts is below.

The Bafang DPC18 from the table's Display row. The readout is km/h in Eunorau's own photograph — the units are a display setting, worth changing before your first ride.

The spec table on Eunorau's page is the R1 line's

If you are comparing this bike on its spec sheet, use the Components list and ignore the table above it.

Eunorau's SPECTER-ST 2.0 page carries a block headed "SPECIFICATION". The entire block, all 18 rows of it, is the R1 line's; none of it is this bike's. Seventeen of its rows appear word for word, in identical order, on Eunorau's R1-17 page, down to the same "Took Kit" typo.

The eighteenth, a 70/100-19 tire row, matches the R1-19's. FASTACE 203mm Travel, 420-106 Links, 203mm Front and Rear Disc, Single Speed, Twist throttle: dirt-bike figures, top to bottom.

Those are e-moto numbers — the R1 line is Eunorau's 55 mph moto range, and 70/100-19 tires and a 420-pitch chain are its sizes rather than a bicycle's. Immediately below that block sits a "Components" list that describes an entirely different machine, and that one matches the photographs, the geometry table and the marketing copy.

Which set is right? The Components list. It agrees with the geometry table, with the eleven product photographs, and with Eunorau's own description of the bike as a 27.5-inch full-suspension step-through with an SRAM NX drivetrain. The specification block does not.

Why it matters to you. Three of those rows would change a buying decision. A single-speed drivetrain on a climbing bike would be a strange choice; 203mm rotors are a different braking proposition from 180mm; and a 203mm fork is a downhill part where 140mm is a trail part. If you compared this bike against another on the spec table, you compared the wrong machine.

Four pistons on a 180mm rotor, per the Components list. The specification block above it says 203mm — one of the eighteen rows that belong to the R1 line.

We will put the discrepancy to Eunorau in writing, along with the missing payload, rider-height and top-speed figures, and publish the answer here. As of 29 August 2026 those questions are open.

What a 160 N·m mid-drive actually buys

A mid-drive puts the motor at the cranks and sends its power through the chain and cassette, so the motor gets the same gear range you do. A hub motor is stuck in one effective gear all the time.

On a hill, that is the whole argument. Drop into the 42-tooth sprocket and the motor's torque is multiplied by the same ratio your legs get. The published figure here is 160 N·m, from a Bafang G510, the motor Bafang also sells as the M620. Bafang's own M620 page rates it at 1000 W with a maximum torque of 170 N·m, so Eunorau's 160 is the more conservative of the two figures.

The torque sensor matters as much as the motor. Eunorau publishes a torque sensor rather than a cadence sensor. A cadence sensor answers one question — are the pedals turning — and delivers a fixed amount of assistance when the answer is yes. A torque sensor measures how hard you are pushing and scales the assistance to match, which is why a torque-sensed mid-drive feels like strong legs and not like a switch.

What you give up is weight and simplicity. 88 lb is heavy, the drivetrain wears faster than a hub motor's because the motor's torque runs through your chain, and a mid-drive costs more to build. On a bike bought for hills, those are reasonable trades. On a flat commute, a hub motor would do the job for less money.

The motor at the cranks, with the chain running back to the eleven-speed cassette it drives. That chain is the whole argument for a mid-drive on hills — and the part that wears for it.

Range: what the 80-mile claim really says

Eunorau's hero strip reads "RANGE Up to 80 Miles (Dual Battery)". Read the bracket: that figure is for two batteries — and as of 29 August 2026, two batteries is simply the configuration delivered. Eunorau includes the 48V 15Ah second pack free at $2,999, and so do we.

Computed from Eunorau's published pack sizes — method in How we verified.

So the 80-mile headline is honest arithmetic for the pair in the box, at a gentle 19.5 Wh per mile. Ride on the main pack alone and the same consumption gives a little over 40; ride it the way a 160 N·m mid-drive invites you to and both numbers shrink.

The same pair against consumption you can plan around:

Plan on the mixed-riding and hill rows instead of the headline: 87 and 62 miles from the pair, 47 and 34 from the main pack alone, if you bought this bike for what it climbs. The second battery is the difference between a long day and a calculation, and it is in the box rather than on an accessories page.

The second colorway. Both ship with the same pair of packs: 840 Wh on the frame, plus the free 720 Wh second battery that turns 43 miles into 80.

For a sense check from outside: Electrek reviewed the previous generation in September 2022 riding a dual-battery setup and estimated 60 miles. We compute no consumption figure from that estimate: the review's own spec box lists a 48V 14Ah battery while its text calls the standard battery "48v 15ah", and it never states which pair the reviewer rode. It is an estimate on an earlier machine, and no measured result on this generation exists.

The step-through geometry, and who it rescues

Eunorau publishes a full geometry table for this machine, printed in a diagram the product page links. The figure to read first is G: Standover, 490mm / 19.3 in.

19.3 inches is low. It is the measurement that decides whether you can get on and off a bicycle without lifting a leg over a bar, and it is the reason this machine reaches riders that a high-step full-suspension bike does not.

One row looks like a misprint and is not: a 615mm top tube on a frame with no top tube. In Eunorau's own diagram the H line runs horizontally from the seatpost to the head tube, across the opening where a top tube would sit; that is the cockpit-length figure to set against a conventional frame's chart when you compare fit.

Eunorau's geometry table, published in a linked image rather than on the page itself — G is the 19.3-inch standover.

What Eunorau does not publish is a payload rating or a rider height range. Neither figure appears anywhere on the page. On an 88 lb full-suspension frame those are the two figures a careful buyer asks for, and we will get them in writing before you order.

Full suspension: what it is and what it is not

The fork is a EUNORAU unit with 140mm of travel, compression adjustment and a lockout. The rear is a DNM AO-38RC listed at 165mm, and Eunorau does not say whether that is the shock's fitted size or its travel. On the sibling SPECTER-S's sheet the same brand's shock is written as "190mm, Travel 50mm", size and travel as separate figures, so read the 165 as the shock's size until Eunorau says otherwise.

140mm of front travel covers roots, rock and washed-out fire road — and it is 63mm short of the fork the spec block claims. The lockout does more work than the number if you spend time on pavement: it stops the fork bobbing under a torque-sensed motor's power.

And it is why the spec-block error is worth catching. That block says a 203mm FASTACE fork — the R1 line's long-travel unit on a bike that actually runs the 140mm EUNORAU fork. Compare suspension on the spec block and you are comparing a fork this bike does not carry.

The fork, photographed on a trail by Eunorau. 140mm of travel with a lockout, per the Components list.

The DNM AO-38RC in the frame. Eunorau lists it at 165mm with no travel figure — the number to ask us for before you order, if rear travel decides it.

The "Class 3" label and the statute

Eunorau's hero strip reads "CLASS: Class 3 Speed limited Unlockable." That label does not survive a reading of the law it refers to.

California's definition is the one quoted here: its text is short, its three-class vocabulary is the one this label is written in, and no other state's statute is read on this page (Limitation 8). Cal. Veh. Code § 312.5 reads, in relevant part:

(a) An "electric bicycle" is a bicycle equipped with fully operable pedals and an electric motor that does not exceed 750 watts of power.

The motor here is 1000 watts. That is 250 watts over the ceiling, and the ceiling sits on the definition of an electric bicycle itself; no class inside it is exempt. The federal definition draws its line at 750 watts as well — phrased "less than 750 watts" at 15 U.S.C. § 2085(b) — and so does the CPSC's bicycle regulation at 16 C.F.R. § 1512.2(a)(2).

The statute's class 3 definition adds a second problem. Section 312.5(a)(3) defines that class as "a bicycle equipped with a motor that provides assistance only when the rider is pedaling, that is not capable of exclusively propelling the bicycle … and that ceases to provide assistance when the bicycle reaches the speed of 28 miles per hour, and equipped with a speedometer."

Eunorau's own FAQ says this bike has a throttle. Asked "Does it have both pedal assist and a throttle?", the page answers: "Yes. The bike offers five pedal-assist levels and a thumb throttle." The statutory test is capability: a machine a throttle can move on motor power alone is what the class 3 definition excludes — § 312.5(a)(4) permits motor-alone movement for start assistance or a walk mode, capped at 3.7 mph. The wattage point above needs no help from this one; both are here because both are on Eunorau's page.

And there is a third gap: Eunorau publishes no top-speed specification for this machine. The listing carries no numeric top-speed row in its stat strip, its spec block or its Components list: a class defined by a speed, asserted with no speed to check it against. The absence has a statutory echo, too. Section 312.5(c) requires manufacturers and distributors to affix a permanent label to each electric bicycle carrying "the classification number, top assisted speed, and motor wattage." We have not inspected this machine's physical label, and (c)'s duty attaches to electric bicycles as the code defines them — so even the label question circles back to the wattage. What the listing publishes is a class and a wattage with no top assisted speed, the middle element of the label the statute prescribes.

None of this makes the bike unlawful to own, and the pattern reaches well past this listing — our review of a 5,000 W machine met the same class question at five times the wattage.

The section has a sale side too, and a buyer weighing this label should read it. Section 312.5(d) provides that certain vehicles "are not electric bicycles under this code and shall not be advertised, sold, offered for sale, or labeled as electric bicycles."

Its first paragraph reaches any two- or three-wheeled 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." Set that beside the strip's own words: "Speed limited Unlockable."

Whether any given listing's feature falls inside that paragraph is for the statute's enforcers to say, and nothing on this page says it. What the subsection tells a buyer is simpler: California polices how these machines may be labeled and sold as well as how they are ridden — one more reason to read the statute instead of the sticker.

What the wattage changes for you is where you may ride. States that adopted the three-class model wrote their own versions of the definition quoted above, and the wording varies.

Where a state routes bike-lane and trail access through a class definition, a machine outside the definition does not inherit the access. Our state-by-state guide carries each state's statute if you want to read yours.

What to do about it. Tell us your state and how you intend to ride, and we will work through what the label means where you live before you order.

Is the battery UL certified?

Eunorau's strip states "UL CERTIFIED: Yes." It names no standard: neither "UL 2849" nor "EN 15194" appears anywhere on the page (checked 29 August 2026).

The distinction the missing number hides: UL 2849 is the system standard (motor, controller, charger and battery certified as one electrical system), while UL 2271 certifies the battery pack by itself. An unqualified "yes" does not say which of the two stands behind an 840 Wh pack, and the difference is the thing an insurer or a building manager asks about.

A third-party retail listing for this bike claims UL 2849 and EN 15194 certification — a claim with no certificate behind it that this page could verify, from a seller who is not the certifying body. If your insurer or your building wants a standard number on an 840 Wh pack, tell us and we will get the certificate from Eunorau before you pay for the bike.

The Mercer fit test

The Mercers are our editorial cast — a fixed group of American riders of different ages, heights and lives that every machine on this site is measured against. Every verdict reads a published number; we have not ridden this bike, so none of them is a ride impression.

The numbers each verdict reads: the 19.3-inch standover, the 32.3"–34.3" saddle height, 88 lb, a torque-sensed 1000 W mid-drive, and the class question above.

The saddle drops to 32.3 inches at its lowest, which is the number to measure your inseam against (the standover only decides the mount). The Components list names a Selle Royal saddle; the saddle in Eunorau's own photograph is branded EUNORAU — ask us to confirm the fitted part before you order.

Read Frank's row against Maya's. Both fit the frame comfortably, and the machine is an easy recommendation for one and a conditional for the other. That is not the bike's doing: it is because Frank rides where the class label does not follow him and Maya rides where it does. Frank, Ruth and Jack get a clean yes; Dana's is a yes on fit and a no on mission; Maya's turns on where she rides. On a full-suspension machine, the standover is what makes even that list possible.

Warranty

Eunorau's published cover is long on the frame and ordinary on the electrics: 10 years on the frame against 24 months on the battery, the motor and the electrical components, manufacturing defects only, wear items and labor excluded.

Three clauses deserve a slower read than the policy table invites. The policy runs to "the original purchaser" and states that the "Warranty does not transfer to another owner" — bought used, the cover is gone. Requirement 3 asks for an "E-bike check-up by a Eunorau specialist or dealer after the first year of use."

And Requirement 6 says products "sold at wholesale or purchased by a business for commercial use (e.g., rental fleets, delivery services, sharing programs) are subject to a 50% reduction of the standard Warranty period", a clause for buyers who are businesses rather than people.

Warranty claims on anything bought from us are handled by us. You send us the fault; we deal with Eunorau.

The honest ledger

Green flags

• A 19.3-inch standover on a full-suspension frame — the geometry that carries the whole review.
• A 1000 W Bafang G510/M620 mid-drive at 160 N·m, with the gearing to use it.
• A torque sensor in place of a cadence sensor.
• SRAM NX 1×11 with an 11–42T cassette — a real drivetrain in place of an entry-level 7-speed.
• 4-piston hydraulic brakes on 180mm rotors with motor cutoff.
• 140mm fork with lockout and a DNM AO-38RC rear shock.
• 1,560 Wh in the box — the 840 Wh main pack plus the 720 Wh second battery, included free ($499 value, verified 29 Aug 2026).
• A decade of frame cover — 10 years, with 24 months on the electrical system.
• A published 12-row geometry table, standover included — on a listing with no payload or rider-height figure, it is the fit data you actually get.

Red flags

• The specification block is the R1 line's — all 18 rows, and three of them would change a buying decision.
• "Class 3" does not survive § 312.5 — 1000 W against a 750 W definition ceiling, with a thumb throttle set against a class the statute builds around pedal-assist propulsion.
• The 80-mile figure needs both batteries on the bike — riding the main pack alone, plan on roughly half.
• No published payload rating on an 88 lb full-suspension frame.
• No published rider height range.
• No published top speed, on a machine labelled with a class the statute defines by speed.
• "UL CERTIFIED: Yes" names no standard.
• 88 lb. Fine to ride, hard to lift, and a two-person job onto a rack.
• The recall check could not be completed on either of two days.

Who should buy it

Buy the SPECTER-ST 2.0 if you want to climb real hills, you want suspension at both ends, and you want to step through the frame rather than over it. Of the 189 e-bikes in our catalog, it is one of two that even attempt that combination — and the only one of the pair built as an eMTB.

Buy the SPECTER-S 3.0 instead if you do not need the step-through. It is the same money and the same motor on a full-frame chassis — our full SPECTER-S 3.0 review covers it, all three free gifts included. The third route is the hardtail FAT-HD 2.0 / Hunter X7: the same mid-drive at $2,399 with the family's biggest payload.

Do not buy it if you need to lift it, if your riding is flat commuting where a hub motor would do the job for less, or if you need the machine to be unambiguously a class 3 e-bike where you ride.

Ask first if bike-lane or trail access is the point of the purchase. That answer depends on your state and on a label this page has tested against the statute and found wanting.

Before you buy: the checklist

• ☐ Compare this bike on the Components list — the specification block above it is the R1 line's.
• ☐ Ask us for the payload rating before you load it.
• ☐ Plan the route on the main pack's 34-to-47-mile band, and carry the free second battery for the long days.
• ☐ Measure your inseam against the 32.3-inch low saddle position.
• ☐ Settle the class question for your state if bike-lane access is the point.
• ☐ Confirm ground-floor storage — 88 lb does not go up stairs.
• ☐ Work out how it gets transported before it arrives.
• ☐ Get the UL standard number from us if your insurer or building asks for one on an 840 Wh pack.
• ☐ Photograph the crate before you open it — transit damage has to reach us inside 48 hours.
• ☐ Decide before you build it: once this bike is assembled, the return window is closed.

Limitations of this review

1. We have not ridden it. No handling, climbing, comfort or noise verdict of our own appears here.
2. The range bands are typical consumption envelopes, not measurements of this machine. No measured range exists from us.
3. Electrek's 60-mile figure is that reviewer's estimate on the 2022 predecessor, on a dual-battery setup whose pack sizes the review states inconsistently — 48V 14Ah in its spec box, "48v 15ah" in its text. It is used as a sense check and no consumption figure is computed from it.
4. Eunorau publishes no payload rating and no rider height range for this model. Its sibling SPECTER-S 3.0 publishes 300 lb and 5'3"–6'4" on its own page, and a third-party retail listing for the ST carries those same two figures; sibling numbers are not this machine's, and neither is repeated here as its specification. We will put both questions to Eunorau in writing; they are open as of 29 August 2026.
5. Eunorau publishes no top speed for this model, so the page reports the absence and does not estimate one.
6. The UL question is unresolved. We report the claim and the absence of a standard number and assert nothing either way.
7. We have not tested the "speed limited unlockable" setting and publish no method for changing it.
8. The class analysis is California's statute. States that adopted the three-class model wrote their own versions, the wording varies, and no other state's rule is asserted here.
9. The recall check could not be completed on 28 or 29 August 2026. We do not know this brand's recall status and do not claim it is clear.
10. The spec-block finding is a documentation error, not a claim about the hardware. We report which block matches the photographs and the geometry; we will put the question of which is authoritative to Eunorau in writing, and it is open as of 29 August 2026.
11. No search-volume figures appear here. We do not publish numbers we cannot source.
12. The two-of-189 catalog figure is our own screen of our own store, run 29 August 2026, every candidate hand-checked against its listing; the screen and its verdicts are committed with this page's dataset. It counts our shelf, not the market.
13. Expiry: re-verify if Eunorau corrects the specification block, publishes a payload rating or a UL certificate, ends the free second-battery offer at either store, or if the price moves.

Frequently asked questions

Is the Eunorau SPECTER-ST 2.0 really a Class 3 e-bike?

Eunorau labels it Class 3, and the label does not hold up against the statute. Cal. Veh. Code § 312.5(a) defines an electric bicycle as having "an electric motor that does not exceed 750 watts of power", and this motor is 1000 W.

Section 312.5(a)(3) adds that a class 3 machine is "not capable of exclusively propelling the bicycle", and Eunorau's own FAQ says this one has a thumb throttle. Check your state before you rely on the label.

Do mid-drive e-bikes have a throttle?

Many do, and this one does — Eunorau's FAQ says "five pedal-assist levels and a thumb throttle". It is worth knowing because a throttle is what separates the class definitions: a class 3 machine under California's statute may not be capable of propelling itself except in a walk mode up to 3.7 mph.

What is the real range of the Eunorau SPECTER-ST 2.0?

Eunorau's "up to 80 miles" is the dual-battery figure — and the bike ships with both packs, free, at Eunorau and here (verified 29 August 2026). The 840 Wh main pack alone works out at about 43 miles at the claim's own consumption; plan on 34 to 47 in real riding, with the 720 Wh second pack making the 80 reachable.

How low is the standover on the Eunorau SPECTER-ST 2.0?

490mm, or 19.3 inches, from Eunorau's published geometry table. That is the figure that lets a rider step through the frame rather than swing a leg over it — and on our own 189-bike shelf, no other full-suspension machine posts one like it.

How much does the Eunorau SPECTER-ST 2.0 weigh?

40 kg, or 88 lb, from row L of Eunorau's published geometry table. On the road that weight mostly disappears under a 160 N·m motor; at the garage door it means ground-floor storage and a two-person job onto a rack.

What motor does the Eunorau SPECTER-ST 2.0 use?

A Bafang G510, also sold as the M620 — a 1000 W mid-drive that Eunorau rates at 160 N·m, driven through a torque sensor in place of a cadence sensor. Bafang's own page rates the motor at 1000 W with a 170 N·m maximum.

Is a mid-drive better than a hub motor for hills?

On a bike like this one, yes. A mid-drive drives the chain, so it uses your gears; drop into the 42-tooth sprocket and the motor's torque is multiplied by the same ratio your legs get. A hub motor is stuck in one effective gear. The trade is weight, drivetrain wear and cost.

Why does the spec table on Eunorau's page not match the bike?

Because the whole block is the R1 line's. Seventeen of its eighteen rows appear word for word, in the same order, on Eunorau's R1-17 page — down to the same "Took Kit" typo — and the tire row (70/100-19, a motorcycle size) matches the R1-19's. Use the Components list below that block — it matches the photographs and the geometry.

Does the Eunorau SPECTER-ST 2.0 have a UL certificate?

Eunorau states "UL CERTIFIED: Yes" without naming a standard, and the string "2849" appears nowhere on the product page. Which of the two e-bike standards is meant — UL 2849 for the whole electrical system, or UL 2271 for the battery pack alone — is not something the page lets you work out. We will ask Eunorau for the certificate on your behalf.

What is the payload capacity of the Eunorau SPECTER-ST 2.0?

Eunorau does not publish one. That is a real gap on an 88 lb full-suspension frame. We will put it to Eunorau in writing alongside the rider height range — both open as of 29 August 2026 — and ask us before you order and we will chase both for you.

Has the Eunorau SPECTER-ST 2.0 been recalled?

We do not know. The CPSC recall service returned errors on every route we tried on both 28 and 29 August 2026, so the check could not be completed and no recall position appears on this page. Ask us before you order and we will run the check again for you, and we will publish the result here when the service is reachable.

What is the warranty on the Eunorau SPECTER-ST 2.0?

Eunorau covers the frame for ten years and the battery, motor and electrical components for 24 months, against manufacturing defects. Worth knowing before you buy: the cover stays with the original purchaser only, a dealer check-up is expected after the first year, and a commercial or wholesale purchase halves the standard warranty period. Buy it here and we run the claim for you.

What is the difference between the SPECTER-ST 2.0 and the SPECTER-S 3.0?

The ST is the step-through; the S is the full-frame version. Both are $2,999 on our shelf and both run the 1000 W Bafang mid-drive. Choose the ST if getting on and off matters, the S if it does not.

The bottom line

The SPECTER-ST 2.0 pairs a serious climbing motor and suspension at both ends with a 19.3-inch standover — in our own 189-bike catalog, only one other machine even attempts the combination. If you have been choosing between a bike you can get onto and a bike that can climb, this is the machine that stops making you choose.

Two things to know before you pay. The spec block on Eunorau's own page belongs to its R1 line, so compare on the Components list. And the "Class 3" label fails § 312.5 — 1000 watts against a 750-watt definition ceiling, with a thumb throttle set against a class the statute builds around pedal-assist propulsion.

Neither changes what the bike does. Both change where you can ride it and what you should compare it against.

Both batteries are in the box. Riding the main pack alone, the honest planning band is 34 to 47 miles; the free second pack is how the 80-mile day happens.

Buy it if the hill is the problem and the top tube is the other problem.
