🛡️ Shengmilo Guarantees & Services

At Shengmilo-USA.com, we believe buying an e-bike should feel just as smooth and powerful as riding one. That’s why every order is backed by real guarantees and responsive U.S.-based service.

✅ 2-Year Warranty
Your e-bike frame is covered for 2 years.
Key components like the motor, display, and controller are protected for 1 year.
If something goes wrong, we’ll ship replacement parts with clear installation guidance — fast and hassle-free. (Shipping costs may apply.)

🔁 14-Day Return Policy
Changed your mind? No problem — return your unused bike within 14 days of delivery.
Just keep it in as-new condition and in the original packaging.
A flat $200 return shipping fee will be deducted from your refund.

🔧 Fast Spare Parts & Repairs
Need help after you’ve started riding? We offer spare parts and repair support even after your warranty ends — always at fair prices.
You’ll get clear troubleshooting instructions and quick responses from our team.

🚚 U.S.-Based Warehousing
All bikes ship directly from our U.S. warehouse, so there are no import duties or customs delays.
Most orders arrive within 3–7 business days, complete with tracking updates.

🤝 Human Support, AI Speed
Our customer service combines instant AI assistance with real people ready to step in whenever you need extra help.
