Eunorau 2-Piston 2.0 Brake Set, 180mm Review

The 2-Piston 2.0 Hydraulic Brake Set pairs 2 piston hydraulic calipers with 180mm disc rotors and 1050mm+1980mm brake tubes, priced at $119. The page calls it an ENA brake sensor set for a high-performance e-bike brake system, says it suits IS and/or Post Mount, and says it fits all ENA/BBS kits from Eunorau and e-bikes with 500W, 750W or 1000W power, and below.

Specifications

Options and pricing

A single variant at $119, in stock when read, with no crossed-out price and no size or color choice. The page includes 180mm rotors in the set and says the brake pads can be replaced with TEKTRO E10.11. It does not say whether levers are included, what the 'brake sensor' in its description refers to, or which pads come fitted.

How it compares

The Eunorau 4-Piston Hydraulic Brake Set with 203mm Rotors is $189 and its page says it is designed for high-output 750W and 1000W eBikes; this 2 piston set with 180mm rotors is $119 and lists 500W, 750W or 1000W and below. The page here adds that bikes below 750W are also compatible but may be a bit of a waste of the set's braking.

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.
