Electric Car Motor Specification Example for Off-Road Bikes: Racing Spec
Electric Car Motor Specification Example for Off-Road Bikes: Racing Spec
This is a worked specification for electric car motor in a racing spec programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.
The racing spec version exists because the duty cycle on off-road bikes is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually packing that arrived crushed at the port.

Example specification
| Item | Electric Car Motor |
|---|---|
| Application | Off-Road Bikes |
| Version | Racing Spec |
| Base material | Sintered Metal |
| Controlled dimensions | 5 key dimensions, recorded per lot |
| Tolerance band | ±0.5 mm |
| Finish | anodised |
| MOQ | 2,000 pieces per specification |
| Sampling | 10 working days, 5 days per revision |
| Compliance | CCC |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Sintered Metal, in this example.
- List the dimensions that are actually controlled and the tolerance on each.
- Name the finish and what it has to survive.
- State the inspection level and who pays when a lot fails.

Processes involved
- injection moulding
- electroplating
- assembly line testing
- precision stamping
- laser cutting
- gravity casting
Where this example applies
Programmes that run racing spec most often specify this build for off-road bikes. Related applications include camper conversions, scooter fleets, agricultural trailers, long-haul trucks, export programmes.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 1.5 sampling on the finished lot.
- Finish inspection under agreed lighting.
- Carton drop test on the first lot of a new packing specification.
Questions buyers ask
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 2000 pieces per line.
How is packing specified?
Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the CCC-compliant build instead of a fresh interpretation.
Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
