Specifications

Options and pricing

One variant at $159, in stock when read, with no crossed-out price. The page lists four compatible sizes (27.2mm, 28.6mm, 30.8mm, 31.6mm) but has no size selector, so it does not say which size is supplied or whether adapters come with it. Length is given as 350mm and the color is black.

How it compares

The page names no sibling part that the seatpost pairs with, saying only that it is compatible with all Eunorau e-bikes. For price context, the Eunorau 2-Piston 2.0 Hydraulic Brake Set with 180mm Rotors is $119, the Eunorau 4-Piston Hydraulic Brake Set with 203mm Rotors is $189 and the Eunorau 27.5 x 3 in Wheel Set for FAT-HS and FAT-HD is $299, against $159 here.

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.
