Step 1:

  • Locate the serial number under the bottom bracket shell of the bike frame.

  • Register your bicycle on the official Diamondback website to activate warranty eligibility.

  • Keep a digital copy of your original purchase receipt from an authorized retailer.

  • Ensure the bike is in original condition, as modifications or repainting can void the warranty.

Step 2:

  • If purchased from a local shop, visit an authorized Diamondback retailer for inspection.

  • If purchased online, submit a support ticket with photos of the bike and issue.

  • Provide serial number details and proof of purchase during the claim process.

  • Ensure the bike has been properly maintained, as damage from misuse is not covered.

Step 3:

  • If a manufacturing defect is confirmed, Diamondback may repair or replace the affected part or frame.

  • Resolution is provided at the company’s discretion based on evaluation.

  • Shipping and labor costs may be the responsibility of the original owner.

  • For non-warranty damage, crash replacement options may be available at discounted pricing.

Diamondback Bicycles Warranty Period:

  • Lifetime warranty on rigid bike frames (for original retail purchasers), five years on full suspension front triangles, and 1‑year coverage on most forks and branded components.
