AI-Powered supplier vetting

SummaryThe supplier demonstrates documented service procedures for corrective and preventive actions and customer complaints, along with stated quality assurance in quality control. It reports experienced electronic and product design teams, recent new-product activity, ODM availability, broad customization options, and OEM service for known brands. Manufacturing evidence includes five production lines, valid contracts with related subcontractors, inventory capability, and an outsourcing SOP. However, the supplier lacks overseas warehouses, showrooms, agents or branches, SDK availability, and documented offline trade-show participation. Continuous quantity reconciliation for each batch or volume production is not performed. No certification records, detailed customer case references, or reliable financial performance evidence are provided in the usable context.

Supplier typeThe supplier is described as Shenzhen Flip Sky Technology Co., Ltd. and is associated with electronic/product design, hardware and micromotor manufacturing, service consumption robots, toys, mechanical components, and related technical services. The available information supports classification as a technology-oriented manufacturer and technical service provider, but does not establish a narrower specialized supplier type.

After-Sales capabilityThe supplier has clear procedures and followed records for corrective and preventive actions and customer complaints, and describes perfect after-sales service. It also has inventory capability, but lacks overseas warehouses, overseas showrooms, overseas agents or branches, and reports zero countries with overseas services, limiting local international support.

R&D capabilityThe supplier reports an experienced electronic R&D and product design team, new products in the past year, technology development activities, and ODM service. It also reports no available SDK, so software-development integration capability is not demonstrated, but the product and technology development evidence supports innovation capability.

Production capacityThe supplier reports five production lines, inventory capability, valid manufacturing contracts with each related subcontractor, and an established outsourcing SOP. However, it does not continuously reconcile quantities for every batch or volume production, which indicates a production-control weakness despite the documented manufacturing resources.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. Its stated individualized product-feature development according to user characteristics and market requirements further supports broad customization capability.

Product Q&A

Q:Do I need professional tools for installation?

The kit includes all necessary components. You can complete the installation with regular tools. However, it is recommended to hire a professional installer for the first time to avoid wiring errors.

Q:Can it be installed on all types of bicycles?

It is mainly suitable for ordinary bikes and mountain bikes. Please confirm the frame load capacity and wheel hub size. Some older models may require additional accessories.

Q:Is speeding modification risky?

It is strongly not recommended! Speeding will significantly increase braking distance and control difficulty, and is highly likely to cause accidents.

Q:How long is the warranty period?

Generally, the battery has a 2-year warranty, the controller has a 1-year warranty, and the frame has a 1-year warranty. For damages caused by human factors (such as falling off the bike), you are responsible for the repair costs.

Q:What should I do if the battery bulges?

Stop using it immediately! The bulge may cause spontaneous combustion. Contact the after-sales service for replacement.
