AI-Powered supplier vetting

SummaryDongguan Keteles Outdoor Sporting Goods Co., Ltd. is identified as a professional electric-bicycle manufacturer. It operates two production lines and has two R&D engineers, with fewer than five quality-control staff. The supplier reports CE product compliance and has written procedures and records for service capability, corrective and preventive actions, and customer complaints. It maintains overseas warehouses and showrooms, including locations in Poland, Germany, the United States, the United Kingdom, Canada, and Australia, but has no overseas agents or branches and has not participated in offline trade shows. R&D is limited to customization from samples; the supplier reports no new product development in the past year, no ODM, and no OEM for popular brands. No supplier-management-system certification is reported, and no Fortune 500 collaboration or recognized design award is stated.

Supplier typeThe supplier describes itself as a professional electric-bicycle manufacturer and operates two production lines. Its overseas service structure includes warehouses and showrooms, but no overseas agents or branches are reported.

CertificationsCE is reported for product compliance and sustainable development/product certification. However, no supplier-management-system certification is reported, so certification coverage is limited to the stated CE information.

After-Sales capabilityThe supplier reports overseas warehouses in six named regions, overseas showroom capability, written and followed procedures for complaints and corrective actions, and lead times within 15 workdays in both peak and off-season. It does not have overseas agents or branches, and the reported number of countries offering overseas services is 0, creating inconsistent or incomplete coverage information.

R&D capabilityThe supplier reports available SDK capability and two R&D engineers, but no new products in the past year, no ODM service, and no internationally recognized design awards. The evidence indicates some technical capability but limited demonstrated innovation output.

Customization capabilityCustomization from samples is explicitly available. However, the supplier reports no ODM service and no OEM service for popular brands, indicating customization is limited in scope rather than broad design and branded-production capability.

Client casesThe supplier reports no collaboration with Fortune 500 companies and provides no named customer cases. A repeat-buyer preference of 10%–30% is stated, but this does not identify or substantiate customer references.

Product Q&A

Q:What types of customization do you offer?

We offer comprehensive OEM/ODM services including custom logos, colors, and graphics on the frame, handlebar, and packaging. We also provide options for batteries, motors, displays, saddles, tires, and lighting systems. Technical specifications like speed and power can be adjusted within legal limits.

Q:What is your Minimum Order Quantity (MOQ)?

For standard models with minor customizations like color and logo, the MOQ starts from 50-100 units. For projects involving unique frame designs or full specification development, we can negotiate the MOQ on a case-by-case basis.

Q:Are your e-bikes certified for international markets?

Yes, we hold international certifications including CE and EN 15194 for Europe, UKCA for the UK, and UL 2849, FCC, GCC, and CPSC compliance for the USA. We can tailor certifications to your specific target market.

Q:What is the sample policy?

Sample fees apply, and shipping is at the buyer's cost. The sample fee is typically deductible from your first bulk order. For standard models, the lead time for a sample is 7-10 working days.

Q:What are your payment terms and production lead time?

We accept T/T with a deposit of 30%-50% required to start production, and the balance paid before shipment. For a standard 40-foot container order, the production lead time is 25-35 working days after sample confirmation and deposit receipt.
