Electric Car Motor Specification Example for Off-Road Bikes: Low Maintenance Version

This is a worked specification for electric car motor in a low maintenance version 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 low maintenance version 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 warranty claims traced back to a single lot.

How the example is built up

  1. Start from the duty cycle, not from the catalogue photograph.
  2. Fix the base material in writing — Sintered Metal, in this example.
  3. List the dimensions that are actually controlled and the tolerance on each.
  4. Name the finish and what it has to survive.
  5. State the inspection level and who pays when a lot fails.

Processes involved

  • laser cutting
  • sintering
  • ultrasonic cleaning
  • assembly line testing
  • robot welding
  • precision stamping

Where this example applies

Programmes that run low maintenance version most often specify this build for off-road bikes. Related applications include scooter fleets, racing teams, long-haul trucks, fleet maintenance, city buses.

Checks before packing

  • Dimensional report against the approved drawing.
  • AQL 2.5 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.

How long does sampling take?

Samples leave the factory in 7 working days, and each revision round adds about 5 days once you have seen the first piece.

What testing is included?

Standard lots ship with dimensional and hardness reports. REACH documentation is issued with the shipment when your market requires it.

What is the minimum order quantity?

The standard MOQ is 200 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.

Send the specification you are working to and we will confirm what we can match, what we would change and why.
