Our verdict

Suits an adult whose head measures within the page's 22-23.2in range and who wants a vented helmet at $39.99 with a stated weight. Look elsewhere if you need another size, a certificate you can check, or a helmet for use beyond pedal cycling and Eunorau e-bikes. The main caveat is that the page shows no certificate or test report behind its standard and certification wording.

Best for
Adults with a 22-23.2in head circumference who want a vented helmet at $39.99.
Skip if
You need a second size or a certificate you can check, since the page lists one size and none.

Why 3.5/5: Held back by the store's published terms for original parts, which do not name this helmet, and by the company's BBB profile (F grade, no accreditation, two unanswered complaints).

An adult bike helmet in Size M, the Genesis is listed at $39.99 in gunmetal grey with an ABS hard shell, an EPS foam core, 6 vents and a dial fit system. The page gives its weight as 489g, plus or minus 10g, and a head circumference of 22-23.2in. It says the helmet complies with GB 811-2022 and is intended only for pedal cyclists and users of Eunorau e-bikes.

Options and pricing

There is one variant, Default Title, priced at $39.99 and in stock when read. The color is gunmetal grey and the only size is Size M; the dial fit system is described as adapting one helmet to a 22-23.2in head circumference, so there is no size choice to make. The page shows no crossed-out price and does not say what else comes in the box.

How it compares

The Eunorau Genesis JR. Bike Helmet for Kids is the kids' model in the same Genesis name, listed at $49.99 against $39.99 here, with PC and shock-absorbing EPS foam as its material where this adult model lists an ABS hard shell and EPS foam. The other siblings are not helmets: the Eunorau C7 Saddle is $39 and the Eunorau TRIKE Saddle is $39.56.

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 no customer reviews. 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. The page shows a live 'people are viewing this right now' counter, which we could not verify.

What we liked

  • Weight is stated as 489g, plus or minus 10g, on the specification list
  • Head circumference is given as 22-23.2in, so it can be compared with a rider's own measurement
  • The page describes 6 vents, an adjustable dial fit system and EPS foam linings it says are easy to remove for cleaning
  • The page names GB 811-2022 and states its intended use: pedal cyclists and users of Eunorau e-bikes

Worth noting

  • Only one size, Size M, is listed, with a 22-23.2in head circumference
  • The page's certification heading names no certifying body, certificate number or test report
  • The special-feature line lists an equestrian design that the page never explains

Questions before you buy

What head size does it fit?

The specification list gives Size M and a head circumference of 22-23.2in. The page says the adjustable dial fit system adapts one helmet to that range and lists an adjustable nylon strap.

How much does it weigh?

The page gives 489g, plus or minus 10g, on the specification list and 489g in its lightweight text. It does not say how the weight was measured.

Which standard does it name and who is it for?

The page says it complies with GB 811-2022 and that it is intended only for pedal cyclists and users of Eunorau e-bikes. It gives no certificate number or test report.

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 page carries a certification heading and names GB 811-2022 but gives no certificate, test report or certifying body, and it names no other helmet standard.
  • The page calls the shell reinforced and the EPS core thickened and says the linings absorb shock, with no impact figures or test method. The special-feature row lists an equestrian design that is not explained.
  • 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.
