Giant Warranty Claims and Authorized Retailer Support
Giant warranty claims generally start through an Authorized Giant Retailer. If you believe your bike, frame, fork, component, helmet, gear, or accessory may have a warranty issue, bring your proof of purchase and the product to a local Authorized Giant Retailer for review.
Giant says warranty decisions cannot be made over the phone or by email in many cases because the product may need to be physically inspected. If the issue involves a safety concern, stop using the product and contact a Giant retailer or Giant support for the official next step.

Online Orders, Shipping, Pickup, and Returns
Giant’s online order process may involve shipment to an Authorized Giant Retailer for assembly and pickup. If your question is about an online order, reply to your order confirmation email or use Giant’s official support options. Bikes, gear, and apparel may have different return rules, time limits, and eligibility requirements.
Bike Registration, Manuals, and Archived Specifications
Giant provides online resources for registering a Giant, Liv, or Momentum bicycle, reviewing owner manuals, and checking older bicycle specifications through its archive. Registration can help store product details and serial number information for future reference, but customers should still keep their own proof of purchase and serial-number records.
Recalls, E-Bikes, and Product-Safety Questions
Giant maintains an official recall-information page for affected bikes, forks, pedals, and other product notices. If you believe your bike or component may be affected by a recall or safety issue, use Giant’s official recall page and contact Giant or an Authorized Giant Retailer. Do not rely on public comments for safety-sensitive issues.

Fraud, Privacy, and Safe Review Tips
When contacting Giant or leaving a public review, protect your private information. Do not post your full address, email address, phone number, payment details, full order number, full bike serial number, login details, accident documents, or photos that reveal private records. If you receive a suspicious message claiming to be from Giant, use the official Giant website, retailer locator, contact form, or verified phone number instead of clicking unknown links.
