How to Adjust the Speed Limit?

DTTZH e-bikes are preset with a speed limit of 20 MPH (approximately 32 km/h). If you wish to experience higher performance speeds in a closed, safe, and private area, this speed restriction can be adjusted. Please contact us directly through Walmart messaging with your order number or screenshot. We will guide you step by step.


What Affects Range and Top Speed?

The actual range and top speed depend on rider weight, terrain, temperature, wind, battery level, and riding mode. Our estimates are based on ideal test conditions with a fully charged battery, average rider, and favorable terrain. Using only throttle mode will reduce the range, while pedal assist mode can help extend it.

Any vehicle failure, damage or safety hazard that is directly caused by an incompatible non-original accessory (especially third-party batteries or chargers) is not covered by this limited warranty. The mere use of non-original accessories does not by itself void warranty coverage for other, unrelated defects. 3.2 Non-Warranty Fault JudgmentThe following faults and damages are not eligible for free warranty repair or replacement, regardless of the 30-day return policy or 1-year core component warranty period: Malfunctions or damage caused by artificial damage, violent collision, falling, extrusion and structural deformation; Damage caused by unauthorized disassembly, structural modification, circuit alteration, or by the use of incompatible non-original accessories; Damage caused by overloaded use, extreme temperature exposure, water immersion and improper daily maintenance; Natural wear and tear of wearable accessories, including screws, rubber parts, plastic parts and bearings; Faults and damage caused by force majeure factors including lightning strikes, floods, fires and traffic accidents. 4.

Shipment and delivery services are generally unavailable on weekends and official U.S. legal holidays (due to warehouse operating schedules). If purchasing both an e-bike and rear rack accessory, the rear rack will be shipped in an independent package to prevent frame scratches and abrasions caused by combined packaging. After the rear rack is dispatched, the independent tracking number will be delivered via service@dttzh.com or Walmart internal message. 5.2 Shipping Damage Inspection & Liability RulesShipping damage incurred during transit is not covered by the standard limited warranty. Free parts replacement is only granted if all the following mandatory conditions are fully satisfied: Submit a formal damage report via service@dttzh.com within 15 calendar days after product receipt. Provide dated, clear and complete photos that fully display all damaged areas of the product. Record all visible scratches, dents and structural damage on the carrier's bill of lading prior to signing for the package.Immediate full inspection upon package receipt is strongly recommended.

We will assess and handle such costs reasonably based on supporting documents. 8. Liability & Legal Supplementary Terms This after-sales policy is formulated in accordance with Walmart platform rules and applicable laws. This policy shall be interpreted in accordance with applicable Walmart platform rules and relevant laws.
