Our verdict
Suits an owner of one of the listed Eunorau bikes who wants a single-wheel steel trailer with stated load and size figures. Look elsewhere if your bike is not on the adapter list or if you need confirmed load behavior, since every figure is the store's own. The main caveat is that the page does not say whether the adapter comes with the trailer, and a note says tire brands may vary.
- Best for
- Owners of a listed Eunorau bike who want a one-wheel steel trailer with stated load and size figures.
- Skip if
- Your bike is not on the page's adapter list or you need proof of the 100 lbs load figure beyond the page's own.
Why 3.5/5: Held back by terms for original parts that leave this trailer unnamed and by a BBB profile with an F grade, no accreditation and two unanswered complaints.
At $329, the Cargo Trailer, 1 Wheel is a steel trailer that the page describes as a fat tire cart for rougher terrain and narrower trails. Its specification lists a loading size of 26 x 16 x 12 inch, a maximum load of 100 lbs, an INNOVA 20 x 4 inch wheel with suspension and a weight of 36 lbs, and a separate adapter list ties it to specific Eunorau bikes.

Options and pricing
One variant, Default Title, at $329, in stock when the page was read, with no crossed-out price and no color or size choice. What changes by bike is the adapter: the page lists Quick-Release for the FAT-HD and FAT-HS, M12 Thru Axle for the SPECTER-S, SPECTER-ST and URUS, and M12 Motor Axle for the DEFENDER-S, FAT-AWD, Rear-drive Flash, Flash AWD, G30-CARGO, UHVO and DEFENDER. It does not say whether the adapter is included in the $329.
How it compares
The Eunorau Hunting Trailer, 2 Wheels is also $329, and the Eunorau E-Bike Hunting Trailer is $369 with two 20 x 3.0 inch wide tires on a steel frame, according to its page. This listing is the one-wheel option, with a 20 x 4 inch fat tire and its own list of bike adapters.
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 100% 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
- Specification block gives loading size, maximum load, material, wheel and weight, with metric figures for size, load and weight
- States a 100 lbs / 45 kgs maximum load for a trailer weighing 36 lbs / 16.5 kgs
- Pairs three adapter types with named Eunorau bike models
- Lists a 20 x 4 inch fat tire with suspension
Worth noting
- The page does not say whether an adapter is included in the $329
- The tire is named as INNOVA, but a COVID-19 note says tire and shifting-system brands may differ
- Compatibility covers only the Eunorau models listed; no hitch dimensions are given for other bikes
- Claims such as access to rougher terrain and a low profile for more cargo weight are the store's own wording

What we couldn’t verify
- A COVID-19 note on the page says shifting-system and tire brands may differ, while the specification names INNOVA tires; the page does not say whether this trailer's wheel can differ.
- The adapter list is flattened in the page text, so the pairing of adapter type with bike group follows its order; the page does not say whether an adapter is included in the price.
- No test, tongue weight, hitch-height range or speed limit is given for the 100 lbs maximum load.
- 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.
