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.
3-Day Free Cancellation
Changed plans? No problem — every order can be cancelled free of charge within 3 days (72h) of purchase.
- Before your payment is captured: full refund, no questions asked.
- After capture: refund minus only the payment processor's real transaction fees — never an arbitrary penalty.
- After 3 days your bike enters production (your build slot is committed with the factory) — cancellations at that stage carry a 10% administrative fee.
- Once shipped, it's handled as a return or warranty case.
