Quality Control for E‑Bikes and Scooters
Checks in our own factory, to the standard you set.
We produce and assemble every vehicle in our own factory in Taizhou, with routine checks during assembly and before packing. For your order we inspect to the requirements you give us, and the 70% balance is paid only after inspection, before the container is loaded.
Flexible MOQ by model, with models mixed in one container; 30–35 days for a full container. We reply within 24 hours on working days.

In brief: BG EBIKE controls quality in its own factory in Taizhou, China, where it produces and assembles about 10,000 electric vehicles a year. Vehicles get routine checks during assembly and before packing. For each order, inspection follows the buyer’s requirements — the buyer’s checklist, sampling level or a third-party inspection company. Payment terms tie quality to money: 30% deposit, and the 70% balance after inspection is completed and before loading; goods ship once paid in full. Vehicles carry a one-year warranty, wear parts are supplied with the order as appropriate, and MSDS and UN38.3 test summary supplied for lithium battery shipments.
From order to loading: where quality is checked
- Configuration agreed. The quotation records model, battery, motor, colours and accessories — the reference for every later check.
- Sample (optional). An approved sample sets the visual and functional standard for the bulk order.
- Production checks. Routine checks during assembly in our own factory.
- Inspection before loading. Done to your requirements: your checklist, your sampling level, your staff or a third-party inspector.
- Balance and loading. The 70% balance is paid after inspection; the container is loaded and ships once paid in full.
What buyers usually ask us to inspect
Inspection follows your requirements. Use the following points to prepare an order-specific checklist:
- Configuration against the quotation: battery version, motor, brakes, tyres and fitted equipment.
- Functions: brakes, lights, horn, display, throttle and start system where fitted.
- Battery and charger pairing for each version.
- Finish: colour, panels, logo position for private label orders.
- Accessories and parts packed with each vehicle, plus any wear parts supplied with the order.
- Packing and marks: cartons, packing frames, carton marks against the packing list and quantities per model.
For a ready-made list, see the pre-shipment inspection checklist.

After delivery: warranty and parts
Vehicles carry a one-year warranty. Wear parts are supplied with the order as appropriate to the models, and further spare parts are sold on their own, so you can keep service stock. For a claim, send the order reference, model, a description of the symptom and photos or a short video; see our warranty claim checklist and order terms and after-sales support.
How should an inspection result be recorded?
An inspection record should connect the requirement, the inspected vehicle and the result. A photograph alone does not show whether the agreed configuration was checked.
- Reference: order, model, configuration version and vehicle or carton identifier.
- Requirement: the quotation line or agreed checklist item being checked.
- Observation: result, measurement units where applicable and supporting photographs.
- Disposition: accepted, correction needed or not checked, with the reason.
- Closure: the correction performed and the result of rechecking that item.
Agree the inspection scope and acceptance criteria before inspection. A catalogue range figure is not an inspection result; a static function check is not a road-range test. Keep unresolved items separate from accepted items when reviewing the order before the balance payment.
Use the warranty documentation checklist for later service cases, so an inspection record and a warranty diagnosis are not treated as the same evidence.

Quality control FAQs
Can I send my own inspector or a third-party company?
Yes. Inspection follows your requirements, so you can send your own staff or appoint a third-party inspection company, and set the checklist and sampling level. Tell us the plan when you order, so the inspection date fits the production schedule.
When do I pay the balance?
The terms are a 30% deposit with the order and the 70% balance after inspection is completed, before the container is loaded. Goods ship once the order is paid in full, so you can release payment only after the inspection result.
What inspection standard do you use?
The standard is the one you set: your checklist and, if you use one, your sampling level. Alongside it, vehicles get our routine checks during assembly and before packing in our own factory.
How long is the warranty?
Vehicles carry a one-year warranty. Wear parts are supplied with the order as appropriate to the models, and other spare parts are sold on their own for your service stock.
Do you supply documents for lithium batteries?
Yes. MSDS and UN38.3 test summary supplied for lithium battery shipments. Lithium battery containers ship as dangerous goods, which takes longer to book and needs more documents, so share your destination early.
