NRCD MINI BIKE KIT

The Mini Race Bike is NRCD's most popular kit — and it's not hard to see why. This is a fully race-proven design, developed and refined on New Zealand racetracks, built to the same spec as the machines competing at the national circuit level.

Students build the entire machine from the frame up:

Engine installation, drivetrain assembly, brake setup, and chassis geometry.

When the build is done, they don't put it on a shelf — they ride it. Available with a 49cc RSA115 full race spec petrol engine or an 800W electric drivetrain, the Mini Race Bike gives schools the flexibility to match the build to their curriculum focus — combustion engineering or electric vehicle systems, both covered in depth.

Pre-built frame options are available for schools that want to focus classroom time on the mechanical systems rather than fabrication.

SPECIFICATIONS

Power

49cc RSA115 petrol or 800W electric

Wheels

10 inch race slicks

Skill Level

Intermediate — Year 11+

Build Time

Approx. 1–2 terms

Students per Kit

2–3 recommended

Frame Option

Self‑fabricate (CAD file included) or pre‑built

WHATS INCLUDED:

Comprehensive parts kit — all mechanical components to complete the build
Frame CAD file for in-house fabrication
Full colour step-by-step assembly manual with technical illustrations
Optional pre-built frame (available on request)
Engine installation guide (petrol and electric versions)
Direct support from Shane throughout the build

Torque specifications, measuring tools, assembly sequences, fault diagnosis, and workshop safety — the full repertoire of practical engineering skills, applied to a real machine.

Workshop Practice

Students read and interpret industry-standard CAD drawings throughout the build, developing the technical literacy that underpins all engineering trades.

CAD & Technical Documentation

Working from the CAD file, students learn how frame geometry affects handling, where structural loads concentrate, and how to fabricate or assemble a chassis to engineering tolerances.

Chassis & Geometry

Students install, set up, and tune either a 49cc RSA115 two-stroke petrol engine or an 800W electric motor — covering fuel systems, ignition timing, chain drive, and final gear ratios (petrol) or motor controllers, battery management, and power delivery (electric).

Engine & Drivetrain

WHAT STUDENTS LEARN

CURRICULUM LINKS

MATHS

Measurement, Ratios, Tolerancing

TECHNOLOGY

Designing, Manufacturing, Technological Systems

PHYSICS

Forces, Motion, Energy Transfer, Rotational Motion

NCEA

Supports Technology and Engineering standards at Levels 1–3

TEACHER NOTE

“This kit keeps students busy all year. The final products are made to a very high standard — and many of our Engineering Academy students take up an apprenticeship when they leave, with employers genuinely impressed by what they've built.”

— Bruce Scott, Head of Technology, Waitakere College

CAREER PATHWAYS:

Builds That Launch Careers

Former NRCD Mini Race Bike students have walked into automotive apprenticeships, motorsport engineering roles, and mechanical trades positions — bringing their build portfolio as evidence of what they can actually do. This isn't a school project. It's a career starter.
