3. Warranty Terms

To provide a satisfactory shopping experience, we offer the following warranty plans for customized products:

3.1.1 The frame product is covered by a 24-month warranty from the date of delivery . The warranty covers manufacturing defects in materials and/or workmanship, and each component can only be replaced once per bicycle.

3.1.2 The motor, controller, lithium-ion battery, bicycle speedometer, and pedal assist sensor are covered by a 12-month warranty from the original purchase date, covering manufacturing defects in materials and/or workmanship. Each component can only be replaced once per bicycle. The battery warranty does not cover damage caused by power surges, improper use of a (non-designated) charger, improper maintenance or other misuse, normal wear and tear, or water immersion.

3.1.3 The hydraulic brakes, front fork, rear shock absorber, battery charger, handlebar stem, handlebars, headset, seatpost, bottom bracket, crankset, rear rack, and drivetrain are covered by a 6-month warranty, which covers manufacturing defects in materials and/or workmanship, and each part is limited to one replacement per bicycle.

If you are unsure whether this is covered under warranty, please contact our customer service.

3.2.3 Wear

Wear and tear refers to damage that occurs naturally and unavoidably during normal riding. For example, even with proper maintenance, your freewheel and chain will eventually wear out and need replacement. Similarly, scratches on the bicycle's paint or pattern, and other potential damage, can occur due to normal use and exposure to various environmental factors. Over time, your bicycle may also develop slight squeaking or other noises during riding, which usually indicates the need for maintenance. Parts that wear out during normal use are not covered under warranty.

These components include, but are not limited to: chain, rims, spokes, brake pads, inner tubes, outer tires, brake discs, grips, hubs, rubber moving parts, derailleurs, brake cables and conduits, stripped threads/bolts, drive gears, saddle, and tools. Maintenance and replacement of these components are the responsibility of the bicycle owner.

Any modification aimed at increasing a vehicle’s continuous rated power by more than 250W or raising the auxiliary speed limit to more than 25 km/h may result in the vehicle being reclassified as a motor vehicle (such as a moped), thereby incurring legal liabilities (such as driver’s license, insurance, and registration requirements) and safety risks.
