1. Battery Cells: The Single Most Important Specification

Key Questions to Ask Your Supplier

• Are the batteries certified to UL 2271 or UN 38.3 standards?

  These are mandatory safety certifications. Without them, batteries may not qualify for shipping or customs import.

• What warranty comes with the battery?

  The industry standard is 12–18 months. Any warranty shorter than 12 months is a major red flag.

• Is the battery removable?

  A removable battery allows indoor charging, ideal if you park outdoors or live in an apartment.

Red Flags

• Supplier unable to state the cell brand

• Proprietary "in-house brand" cells without third-party certification

• Battery warranty of less than 6 months

• Unrealistically low pricing (cost savings almost always come from downgraded batteries)

2. Motor: Focus on Continuous Rated Power, Not Peak Power

Key Questions to Ask

• Hub motor or mid-drive motor?

  Hub motors have simpler structures and lower costs, suited for urban flat-road riding. Mid-drive motors deliver superior hill performance but come at a higher price.

• What brand is the motor?

  Bafang, Bosch, Shimano and Yamaha are established premium brands. Unbranded generic motors carry significant risks.

• Does the motor carry an IP waterproof rating?

  IP65 or higher enables safe riding in rain and over puddles.

Red Flags

• Only peak power stated, no continuous power rating provided

• Unbranded motor with no official specification sheet

• A bike priced at $600 claiming a 5000W motor (technically impossible at that price point)

3. Certifications: The Passport to Your Target Market

Mandatory Certifications by Major Markets

Key Questions to Ask

• Can you provide an EU / US / AU Declaration of Conformity?

  Legitimate exporters maintain these documents on file.

• Has this model previously been shipped to my country?

  If yes, they should be able to share supporting import documentation.

Red Flags

• Offers to "apply a CE sticker for you" (indicates counterfeit certification)

• No understanding of your country’s import regulations

• Reluctance to share certificate numbers or test reports

4. Shipping & Logistics: The Hidden Cost Factor

Realistic Cost Breakdown

Key Questions to Ask

• Do you offer consolidated sea freight?

  Consolidation with other shipments drastically cuts costs for small orders.

• What is the full lead time from order placement to delivery?

  Typical timeline: 7–14 days production + 25–40 days sea transit + 3–7 days customs clearance and local delivery. Total lead time: 35–60 days.

• What packaging standard do you use?

  Bikes should be packed in reinforced cartons with foam cushioning, steel frame supports, and wooden pallets for bulk shipments.

Red Flags

• Unable to provide DDP or DAP pricing

• Only vague description of "standard carton packaging" with no details

• Unrealistically fast delivery commitments (door-to-door transit under 20 days via sea freight is generally unachievable)

5. After-Sales Support: The True Test of a Reliable Supplier

Key Questions to Ask

• Do you maintain spare parts inventory?

  If brake pads, controllers and displays are not stocked, repairs will face lengthy delays. Request a spare parts catalogue.

• How are warranty claims processed?

  Standard workflow: submit photo/video evidence of faults → supplier diagnosis → shipment of replacement components.

  If they require you to ship the entire bike back to China, this is not viable after-sales support.

• Can I contact one of your existing customers as a reference?

  Confident suppliers are willing to provide references. Hesitation should raise suspicion.

• What is your typical response time for support enquiries?

  Professional exporters aim to reply within 24 working hours.

Red Flags

• No formal written warranty documentation

• Claims of "zero warranty claims to date" (impossible for established production volumes)

• No spare parts stock available

• Support response takes multiple days

• Cannot supply customer references

Bonus: Factory Inspection – If You Can Arrange a Visit

• Organised production lines (not bikes stacked randomly in warehouses)

• Dedicated QC testing station – every unit must be tested before packing

• Battery assembly room: clean, dry and temperature-controlled environment

• Spare parts warehouse, confirming long-term after-sales capability
