7. Return and Refund Policy

DYU's published US return policy allows customers to request a return within 30 days of receiving an eligible order.

However, the policy includes important conditions:

1. Products must meet the required return condition.
2. E-bikes must generally be unused or show fewer than 10 kilometres on the display.
3. Original packaging, accessories, and proof of purchase are required.
4. Non-quality-related returns may involve shipping and restocking deductions.
5. Customers should contact DYU before sending products back.
6. Defective products may qualify for a return, exchange, or other resolution, depending on the circumstances.

For non-defective e-bike returns, the policy lists a $200 shipping deduction per bike, in addition to applicable restocking fees.

Refunds are processed after the returned product has been received and inspected.

Important buying consideration: DYU's terms of service also contain separate references to a 7-day damaged-on-arrival guarantee and a 10-day money-back provision. These statements do not align perfectly with the dedicated 30-day return policy. Shoppers should contact customer support and obtain written confirmation of the applicable return terms before purchasing.

8. Warranty and Customer Support

DYU advertises warranty coverage for its electric bikes, but shoppers should check the exact warranty terms for their selected model.

The dedicated warranty page describes a one-year limited warranty covering manufacturing defects for the original purchaser. It also explains that free accessories are excluded from warranty service.

The homepage and sale pages advertise 12–24 months of coverage for certain core components. Because these statements describe different coverage periods, customers should confirm the applicable coverage for their exact bike and components before ordering.

2. Cooperation inquiries: official@dyucycle.com
3. Official Contact Page
4. Warranty Information

Its selection includes compact folding models, commuter-oriented bicycles, and fat-tire options. The availability of product specifications, comparison tools, manuals, and support information can help shoppers evaluate different models before ordering.
