2-Year Warranty
Every Twitter bike is covered by a 2-year warranty against manufacturing defects, frame and components included.
- Claims handled directly by our team. Fast and customer-first.
- Depending on the case we repair, send the part, replace or refund.
- Contact: warranty@twitterbikeusa.com. Photos and your order number speed things up.
Make-It-Right Guarantee
Our goal is simple: if something isn't right, we make it right.
- Arrived defective, damaged or incorrect? Tell us within 7 days of delivery with photos (keep the packaging).
- We resolve it: repair, spare part, replacement or refund, whichever fits the case.
- If the bike is unusable and we can't resolve it: full refund and collection, or a replacement.
