Quick answer

The Eunorau SPECTER-ST 2.0 is a 1000W mid-drive, full-suspension step-thru eMTB, listed by Eunorau as Class 3 with a UL-certified battery. $2,999 with free shipping in the lower 48 — and the second 48V 15Ah battery is included free, so Eunorau's 80-mile dual-battery range figure describes the setup you actually receive.

Class, speed & certification

E-bike class

Class 3 Speed limited Unlockable

Class rules are set by state and local law in the U.S. Check the rules where you ride — some paths and trails restrict Class 3.

UL certified

Yes — as published by Eunorau. UL listing for the battery and electrical system is what many U.S. cities, insurers, and apartment buildings now ask for.

Who the SPECTER-ST 2.0 is for

Buy it if

  • Loose, steep, or broken ground — sand, gravel, snow, and root-covered trail
  • Riders who need a UL-certified battery to charge indoors
  • Long days out — the second 48V 15Ah battery ships free with the bike, and Eunorau's published 80-mile range is for exactly that dual-battery setup
  • Anyone who wants a genuine step-through on a full-suspension eMTB — the published standover is 490mm/19.3in

Or one of these instead

  • Riding where Class 3 machines are barred from paths and trails? The Eunorau URUS 2.0 is the 20 MPH full-suspension eMTB in our range — same brand, path-friendlier published speed.
  • Need a bike you can lift every day? At a published 88 lb this one rewards a garage; the URUS 2.0 is published at roughly 61.7 lb.
  • Want a published payload rating and a full frame? The SPECTER-S 3.0 (Hunter X9) is the same $2,999 with a published 300 lb payload capacity.

Fit

Size, fit and capacity

Eunorau SPECTER-ST 2.0 Step-Thru eMTB — Motor and drivetrain
Power

Motor and drivetrain

Mid-drive 1000W motor with a SRAM NX 1×11-speed shifter and 11-42T cassette.

The honest ledger

Green flags

  • Second 48V 15Ah battery included free with the bike — a $499 accessory on Eunorau's own page, verified 29 Aug 2026 — and the 80-mile range figure Eunorau publishes is for the dual-battery setup
  • UL certified, per Eunorau — increasingly what US cities, insurers and apartment buildings require before an e-bike can be charged indoors
  • Suspension at both ends — EUNORAU 140mm-travel fork up front, DNM AO-38RC shock at the rear
  • Hydraulic disc brakes with motor cut-off levers and 180mm rotors, and a SRAM NX 1×11-speed drivetrain

Red flags

  • Class 3 is a restriction as well as a feature — many US bike paths, parks and multi-use trails bar Class 3, so check your local rules before buying
  • 88 lb (40 kg) is heavy — fine on the road, awkward on stairs or a car rack
  • Eunorau publishes no maximum speed for this model, so we do not state one and you should not infer a US class from its wattage
  • Eunorau publishes no payload capacity for this model — email us and we will ask them rather than guess

What it covers

Manufacturing defects in Eunorau's original parts and components.

Eunorau states it continues to support the product after the warranty period as a manufacturer courtesy, and may ask only for shipping costs on replacement parts.

What you must do

  • You are the original purchaser — the warranty does not transfer
  • Proof of purchase (your Redtail order confirmation)
  • Product registration with Eunorau right after purchase
  • An e-bike check-up by a Eunorau specialist or dealer after the first year of use

Not covered

  • Ordinary wear and tear — brake pads, rotors, spokes, grips, shifters, brake cables and casings, tires and tubes, chains, chainrings, cassettes, transmission gears
  • Labor charges for part replacement
  • Corrosion from moisture or heat, and cosmetic deterioration of the finish
  • Damage from accident, abuse, stunt riding, racing, improper storage, or neglect

24-Month+ Limited Warranty issued by Eunorau Bikes, a Nevada corporation. Bikes bought for commercial use — rental fleets, delivery, sharing programs — get a 50% reduced warranty period. Full terms are published by Eunorau at eunorau-ebike.com/pages/warranty. Redtail coordinates warranty claims for bikes bought from us, so send it to us rather than to Eunorau: support@redtailebikes.com.

Manuals & documentation

In the box

Eunorau's spec sheet for this model lists a printed manual and a tool kit as included.

Any other document

Eunorau publishes display, controller, shock and accessory manuals across several files. Tell us which one you need and we will send you our copy, so you are not hunting through a supplier download hub.

support@redtailebikes.com

Eunorau publishes display and component manuals rather than a per-bike user manual. We link only the manual Eunorau lists against this exact model. Need a document we haven't linked? Email support@redtailebikes.com and we'll request it from Eunorau.

Shipping, returns & support

Shipping

Free shipping on every electric bike within the contiguous United States (lower 48).

Orders are prepared and dispatched within 1–3 business days. Most e-bikes arrive within 5–10 business days after dispatch.

Ships via UPS, FedEx, or LTL freight for larger items, with tracking emailed at dispatch. Freight deliveries may need a scheduled appointment and a signature.

On delivery

Inspect your shipment at delivery. Damage, defects, or incorrect items must be reported with photos within 48 hours.

If a bike arrives dead, won't charge, throws an error code, or has a faulty component, it is covered under the manufacturer warranty and Redtail coordinates repair or replacement remotely.

Returns

Change-of-mind returns accepted only on unopened, factory-sealed items requested within 72 hours of delivery, with a 15% restocking fee plus return shipping. Once a box is opened or a bike is ridden, it is no longer eligible.

Order cancellations carry a 3% transaction fee, because card-processing fees are non-recoverable.

Alaska, Hawaii, U.S. territories, P.O. boxes, and remote areas may incur extra charges or be excluded — contact us before ordering. Full terms: Shipping Policy · Refund & Return Policy.

Frequently asked questions

How fast is the Eunorau SPECTER-ST 2.0?

Eunorau does not publish a maximum speed for this model, so we won't state one. Because U.S. e-bike class is defined by assisted speed, you should not infer a class from its wattage. Email support@redtailebikes.com and we'll ask Eunorau.

Is the Eunorau SPECTER-ST 2.0 UL certified?

Yes — Eunorau lists this model as UL certified. In the U.S. that increasingly determines whether you can store and charge the bike inside an apartment building, and some insurers ask for it too.

What warranty covers the Eunorau SPECTER-ST 2.0?

Eunorau's 24-Month+ Limited Warranty: 10 years on the frame and 24 months on the battery, motor and electrical components, covering manufacturing defects. It requires registration with Eunorau after purchase, applies to the original purchaser only, and excludes wear items and labor. Redtail coordinates claims for bikes bought from us.

How does the SPECTER-ST 2.0 ship, and can I return it?

Free shipping within the contiguous U.S., dispatched in 1–3 business days and typically delivered 5–10 business days later. Inspect it at delivery — damage or defects must be reported with photos within 48 hours. Unopened change-of-mind returns are accepted within 72 hours with a 15% restocking fee plus return shipping.
