Eunorau 27.5 x 3 in Wheel Set for SPECTER-S Review

A 27.5 x 3 in wheel set made for the SPECTER-S, listed at $399 and described as a thru axle design, with Kenda or Chaoyang tires. It suits SPECTER-S owners who have disc rotors and a front thru axle, since the page says neither is included.

Our verdict

Intended for a SPECTER-S owner who wants a 27.5 x 3 in wheel set and already has, or will buy, disc rotors and a thru axle. Look elsewhere if you want to choose the tire brand, run a different model, or need weight and hub figures. The main caveat is that the page's detail stops at the tire and the list of what is not included.

Best for
SPECTER-S owners who want a 27.5 x 3 in wheel set and will supply their own disc rotors and thru axle.
Skip if
Your bike is not a SPECTER-S, you want to pick the tire brand, or you need weight and hub spacing stated on the page.

Why 3.4/5: Held back by a short page of a few lines and a price, by published terms for original parts that never name this wheel set, and by the company's BBB profile (F grade, no accreditation, two unanswered complaints).

Made specifically for the SPECTER-S, this wheel set carries a $399 price, 27.5 x 3 in tires and, according to the page, a thru axle design. The tire, a Kenda Havok or Chaoyang, is described with a reflective sidewall stripe, a K-Shield puncture-resistant liner, a wire bead and a 30 TPI casing. The page states that the wheelsets do not include disc rotors and thru-axle.

Options and pricing

A single variant at $399, in stock when read, with no crossed-out price and no size or color choice. The page says the tire brand will be Kenda or Chaoyang, assigned at random from the warehouse, so it cannot be selected. Disc rotors and the thru-axle are not included, and the page's note names the front axle thru specifically.

How it compares

Listed at $399, this set sits above the Eunorau 27.5 x 3 in Wheel Set for FAT-HS and FAT-HD at $299, whose spec line also says disc rotors are not included. The Eunorau Tektro 4-Piston Hydraulic Brake Set, 203mm Rotor is $299 and carries its own 203mm rotor, but neither page says the two are meant to go together.

Shipping, returns and warranty

Shipping: the shipping page says accessories and batteries go by FedEx or UPS in an estimated 5 to 9 days after 1 to 3 business days of processing; orders over $100 ship free and smaller orders pay $14.99, with a possible remote-area charge. If the local warehouse is out of stock, the item ships from an overseas warehouse in an estimated 10 to 15 business days, and there may be no carrier tracking until it reaches the destination country and clears customs. Returns: an order can be cancelled for a full refund before it ships or is produced, but not after it ships; the page asks buyers not to refuse a delivered e-bike and to contact the store instead. A return must be applied for within 7 calendar days of receipt, the product must be new and re-sellable (not assembled, ridden, used or damaged) and complete with its manuals, accessories and original packaging, and the buyer ships it back within 7 days at their own cost to Eunorau's warehouses in the US, Australia, Europe or the UK. The store inspects it within 5 days and refunds in full when the fault is Eunorau's (wrong, damaged or defective item) or minus the shipping cost when the reason is the customer's. The terms page says customers are charged shipping only once, returns included, with no restocking fee, which does not match the return page's wording. Warranty: the warranty page covers original Eunorau parts and components for 24 months (manufacturing defects only, no labor) but excludes wear items, free gifts and accessories that came with a purchase, and damage from unapproved accessories or chargers; it does not name this item, so ask support whether and how it applies. It is for the original purchaser and excludes shipping damage. Disputes under the warranty go to binding individual arbitration (AAA rules, Nevada law) unless the buyer emails an opt-out within 30 days of purchase.

Before you buy

The page shows 1 customer review with 0% of them five-star in the store's own widget, which we could not verify; several product pages show the same review counts or lists, so the figure may not belong to this item alone. Reputation: Eunorau E-Mobility USA Corp has an F grade on the Better Business Bureau, is not BBB accredited and has 2 complaints on file, both marked unanswered: a December 2025 request for proof that a bike sold as new was new, and a May 2025 report of a battery cover that would not latch, which the buyer attributes to a frame defect. A web search on 21 October 2026 found no Trustpilot page for Eunorau. The store says it has specialised in e-bikes since 2009 and designs its bikes in the US and manufactures them in Shanghai, while the BBB lists a business start date of 12 December 2019; the eunorau-ebike.com domain was registered on 27 July 2016.

What we liked

  • Names the one model it is for, the SPECTER-S
  • Tire size, bead and casing are stated: 27.5 x 3 in, wire bead, 30 TPI
  • States up front that disc rotors and the thru-axle are left out
  • Describes the tire as having a reflective sidewall stripe and a K-Shield puncture-resistant liner

Worth noting

  • Fits only the SPECTER-S per the page, and the front axle thru is not included
  • The tire brand, Kenda or Chaoyang, is a random warehouse pick, so it cannot be chosen
  • Weight, rim width, spoke count and hub spacing are all missing
  • The page does not say which disc rotors or thru axle to buy for it

Questions before you buy

What is not included with the wheel set?

The page says the wheelsets do not include disc rotors and thru-axle, and its note says the front axle thru is not included. It does not say whether a rear axle is included.

Which bike does it fit?

The page lists only the EUNORAU SPECTER-S, and says the wheelset for the SPECTER S is Axle Thru.

What tires come on it?

The page names a Kenda Havok or Chaoyang tire and gives the brand as a random pick from warehouse stock. It lists a reflective sidewall stripe, a K-Shield puncture-resistant liner, a wire bead and a 30 TPI casing at 27.5 x 3 in.

How are Eunorau accessories and batteries shipped?

By FedEx or UPS, an estimated 5 to 9 days after 1 to 3 business days of processing; free over $100, otherwise $14.99. If local stock is out, the item ships from an overseas warehouse in an estimated 10 to 15 business days, possibly without tracking until it clears customs.

What is the return window?

The return page gives 7 calendar days from receipt to apply. The item must be new, unused and complete in its original packaging, and the buyer pays the return shipping to Eunorau's warehouse; the refund is full only when the fault is Eunorau's. Orders can be cancelled for free before they ship.

What does the warranty cover?

The warranty page covers original Eunorau parts for 24 months but excludes wear items, free gifts, accessories bundled with a bike and labor, and it does not name this item, so ask support whether it applies.

What we couldn’t verify

  • The description's opening line says the wheelsets exclude the thru-axle while the note names only the front axle thru as not included in the parcel, so the page does not say whether a rear axle is included.
  • The tire brand, Kenda or Chaoyang, randomly ships out from the warehouse, and no weight, rim width, spoke count or hub spacing is given.
  • The return page says the buyer pays return shipping, while the terms page says customers are charged shipping only once, returns included, with no restocking fee.
