AI-Powered supplier vetting

SummaryShenzhen Gravity Technology Co., Ltd. is a China-based trading company established in 2017, focused primarily on electric bikes and related bicycle products. It reports electric-bike output of 200,000 pieces, three production lines, six to ten quality-control staff, and peak-season fulfillment of two to three months. The supplier offers OEM and ODM services, exports to multiple global regions, and reports lifelong service, fast response, and customer suggestions as part of its service system. However, the provided information does not include certifications, verified customer cases, or sufficient evidence to assess financial credibility. The supplier shows documented product development and customization capabilities, but its trading-company classification and limited operational details mean production resources and manufacturing control should be verified further.

After-Sales capabilityThe supplier states that it provides lifelong service, fast response, constructive customer suggestions, and one-stop support intended to help customers improve profits and market share. These are explicit service commitments, but no service-level metrics or independently verified performance evidence is provided.

R&D capabilityThe supplier explicitly offers OEM and ODM services and reports three years of R&D engineer experience. This supports a documented product-development capability, although the slices do not provide examples of innovations, patents, or completed development projects.

Production capacityThe supplier reports electric-bike output of 200,000 pieces, three production lines, six to ten quality-control staff, and one-month off-peak lead time with two-to-three-month peak-season fulfillment. These figures provide explicit evidence of production capacity and operational structure, although the company is classified as a trading company and the relationship between its own facilities and external production is not clarified.

Customization capabilityOEM and ODM services are explicitly stated as available for electric bikes and related products. This directly supports customization capability, though the scope of customization, minimum order requirements, and technical process are not specified.
