Design and build bicycle frames


Application

This unit describes the performance outcomes required to design and build a bicycle frame. It involves preparing for the work, selecting and using specialist tools and equipment, identifying different frame materials and components, determining rider measurements, assembling the bicycle frame to customer specifications, and completing workplace processes and documentation.

It applies to those working in the bicycle retail, service and repair industry.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.


Elements and Performance Criteria

4.3 Hazards associated with the work are identified and risks are managed

4.4 Design drawing angles, measurements and frame alignment are checked throughout the building process and adjustments are made as required

5. Paint and finish frame

5.1 Frame is prepared for painting and finishing

5.2 Paint or finish is prepared and applied according to job and customer requirements and workplace instructions

5.3 Safety and environmental requirements, including the use of PPE and adequate ventilation during frame painting, are followed

5.4 Visible paint defects are removed or repainted according to workplace procedures and quality requirements

6. Complete work processes

6.1 Final inspection is made to ensure work meets workplace expectations and bicycle is presented ready for use

6.2 Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected and stored

6.3 Tools and equipment are checked, reported if faulty, and stored according to workplace procedures

6.4 Workplace documentation is processed according to workplace procedures

Assessment Conditions

Assessors must satisfy NVR/AQTF assessor requirements.

Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.

Assessment must include direct observation of tasks.

Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the bicycle frames they have designed and built, e.g. build orders.

Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.

The following resources must be made available:

bicycle workplace or simulated workplace

workplace instructions detailing job requirements and build instructions

customer build requirements

relevant technical information and bicycle frame component specifications

PPE required to build a bicycle frame

bicycle CAD or other design tools

bicycle sizing measuring equipment

bicycle parts and components to build two different bicycle frames specified in the performance evidence

access to suppliers of bicycle parts

tools and equipment appropriate for designing and building bicycle frames.
