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.

Twitter M5 Boost
Engineered for fast XC riding and confident trail control, the Twitter M5 Boost is a high-modulus carbon hardtail built around a stiff, lightweight monocoque frame. Boost thru-axle spacing, fully internal cable routing, and a magnesium-aluminum air-suspension fork with remote lockout deliver precise handling on the climbs and composure on the descents. Choose from three wide-range 1x drivetrains — including a wireless 13-speed option — all paired to hydraulic disc brakes and grippy 29" tubeless-ready tires.
Key Features
- ▪ M5 High-Modulus Carbon Fiber Frame with XC geometry, internal cable routing and Boost 12×148 mm thru-axle.
- ▪ TW Air-Suspension Fork (magnesium-aluminum alloy) with remote lockout and Boost 15×110 mm thru-axle.
- ▪ Three 1x Drivetrain Options — SHIMANO DEORE M6100 12-speed, WheelTop EDS OX 13-speed wireless, or SRAM SX Eagle 12-speed.
- ▪ Wide-Range 11–50T Cassette for a huge climbing-to-sprinting gear spread on every configuration.
- ▪ SHIMANO MT200 Hydraulic Disc Brakes (160/160 mm) for consistent, all-condition stopping power.
- ▪ RS Disc Wheelset on 4-sealed-bearing Boost hubs with MAXXIS 29" (27.5") × 2.2" tires.
