AI-Powered supplier vetting
SummaryQingdao Zhengya Rubber Industrial Co., Ltd. is a China-based manufacturer established in 2011, with 98 employees and a 11,700 m² manufacturing plant. Its stated product range covers motorcycle, bicycle, wheelbarrow and related tires and inner tubes. Reported production includes 550,000 motorcycle tires and 6,000,000 motorcycle inner tubes annually, supported by two production lines and 6–10 quality-control staff. The supplier reports export activity since establishment, with 90% of sales from exports and markets across South America, Africa, Southeast Asia/Middle East, East Asia and North America. However, no supplier-management-system certifications are reported, and evidence is insufficient to assess after-sales service, customization, or innovation comprehensively. Trade records identify ROAM ELECTRIC LIMITED as an associated buyer and show motorcycle-tire-related transactions, providing limited customer-case evidence.
Supplier typeThe supplier is explicitly identified as a manufacturer and factory, organized as a limited company in China. Its stated business is rubber and tire-product manufacturing, with a dedicated 11,700 m² plant and products including motorcycle, bicycle and wheelbarrow tires and inner tubes.
CertificationsThe supplier-management-system certification field is explicitly reported as NIL. No certification evidence is provided in the available slices, indicating a stated absence of such certifications.
Production capacityProduction capability is supported by the manufacturer status, a 11,700 m² plant, two production lines, 6–10 quality-control staff, and stated annual output of 550,000 motorcycle tires and 6,000,000 motorcycle inner tubes. The supplier also reports one-month lead times in both peak and off-peak periods, although the slices do not independently verify these capacities.
Client casesTwo trade-record slices identify ROAM ELECTRIC LIMITED as an associated buyer and show motorcycle-tire-related products, including components for electric motorcycles and 90/90-17 motorcycle tires. These records provide evidence of at least one buyer relationship and relevant product transactions, but they do not establish customer satisfaction, repeat orders or the broader scale of the customer base.
Product Q&A
Q:What is the purpose of a motorcycle inner tube?
A:
The inner tube holds the air pressure inside the tire, providing a smooth ride by absorbing shocks from the road. It also helps maintain the tire's shape and ensures optimal performance.
Q:What material is a motorcycle inner tube made from?
A:
Motorcycle inner tubes are typically made from butyl rubber, a synthetic rubber known for its excellent air retention properties and resistance to heat, abrasion, and aging.
Q:How do I know what size inner tube to buy for my motorcycle?
A:
The size of the inner tube should match the size of the tire. This is usually indicated by a series of numbers printed on the tube, such as '3.00-18'. The first number represents the width of the tube in inches, and the second number represents the diameter of the wheel in inches.
Q:What is the difference between Schrader and Presta valves?
A:
Schrader valves are more common on motorcycles and are wider and shorter than Presta valves. They also have a spring-loaded mechanism that seals the valve when it's not in use.
Q:How often should I replace my motorcycle inner tube?
A:
The frequency of replacement depends on the condition of the inner tube. It's important to regularly check the condition of the inner tubes and replace them if they're damaged or worn. A common sign of a problem is a slow leak, which can cause the tire to gradually lose air pressure.
