What Is a Cyclekart?

A cyclekart is a small, lightweight, vintage-inspired car built for fun, creativity, and hands-on motoring. Most cyclekarts are home-built by enthusiasts using simple materials, small engines, motorcycle-style wheels, and basic mechanical parts.

They are not full-size race cars, go-karts, or replicas in the strict sense. A cyclekart is more about capturing the spirit of early motoring than copying every detail perfectly.

Think of them as small, character-filled machines inspired by the cars of the early 1900s through to the 1930s. They are simple, mechanical, approachable, and built to be driven and enjoyed. Whilst most countries in the world limit cyclekarts to the pre-war golden age of motoring, in Australia due to our unique motoring history, there is no set time limit on cyclekarts. As long as it is "Vintage" and an open wheeler it is fair game for everyone.

Where Did Cyclekarts Come From?

Cyclekarts started as a grassroots hobby built around simple home construction, vintage styling, and low-cost fun. It was started by the Stevenson Family in California, USA in the mid 90s. For the full history, visit www.cyclekarts.com

The idea is to build a small car inspired by early racing and sporting cars, often using readily available parts rather than expensive specialist components. Builders might take inspiration from Bugatti, Austin, MG, Riley, Peugeot, GN, ERA, Amilcar, or other early motoring designs.

The goal is not to build an exact replica. The goal is to create something that looks, feels, and drives in the spirit of those early machines.

That is part of the charm. Every cyclekart is different.

What Makes a Cyclekart Different From a Go-Kart?

Cyclekarts and go-karts share some basic parts, but they are not the same thing.

A go-kart is usually designed around performance, track use, and compact racing-style handling. A cyclekart is usually designed around character, creativity, and vintage-inspired motoring.

The main differences are:

• Cyclekarts usually have vintage-style bodywork
• They often use larger diameter wheels, commonly around 17 inches
• They are generally longer and narrower than typical go-karts
• They are built to resemble early cars rather than modern racing karts
• The driving experience is more about enjoyment than outright speed
• Many are built at home by hobbyists

A cyclekart might use go-kart components such as hubs, axles, bearings, sprockets, brakes, and steering parts, but the overall machine has a very different feel and purpose.

What Engine Does a Cyclekart Use?

Many cyclekarts use a small industrial engine such as a Honda GX200-style engine or similar clone engine.

These engines are popular because they are:

• Simple
• Affordable
• Reliable
• Easy to maintain
• Widely supported with parts
• Well suited to lightweight vehicles

A typical cyclekart is not about huge horsepower. In fact, part of the fun is making a small engine feel exciting in a lightweight, open machine.

Some builders also experiment with electric drive systems, but small petrol engines remain common because they suit the traditional mechanical feel of the hobby.

How Fast Is a Cyclekart?

Cyclekarts are not built to be high-speed racing cars.

Speeds vary depending on the engine, gearing, tyres, terrain, and build quality, but the real appeal is not top speed. The appeal is the feeling of driving something mechanical, open, lightweight, and built by hand.

Because the driver sits low and exposed, even modest speeds can feel exciting.

A good cyclekart should feel lively and engaging without needing to be dangerously fast.

What Are Cyclekarts Made From?

Most cyclekarts are built from a simple steel chassis, often using rectangular hollow section steel. The body may be made from aluminium, plywood, fibreglass, steel sheet, or a combination of materials. Recycling and repurposing is throughly encouraged! Builders have used anything and everything, from above ground pools and fibreglass ladders, to kitchen sinks and ironing boards to complete their builds.

Common cyclekart parts include:

• Steel chassis
• 17 inch motorcycle or pit bike style wheels
• 25mm rear axle
• Pillow block bearings
• Wheel hubs
• Chain and sprocket drive
• Hydraulic rear brake
• Simple steering system
• Leaf springs or other simple suspension
• GX200-style engine
• Vintage-inspired bodywork

One of the best things about the hobby is that there is room for different approaches. Some builders make highly detailed machines with beautiful bodywork, while others build simple, rugged cars designed to get driving as soon as possible.

Both approaches are valid.

Do You Need to Be an Engineer to Build One?

No.

That's the best part. Cyclekarting is the cheapest and most grass roots entry into any four wheel motorsport or motoring hobby worldwide. Learn as you go and have fun with it.

You do need patience, care, and a willingness to learn, but you do not need to be a professional engineer to build a cyclekart.

Many cyclekart builders are hobbyists working from a home garage or small shed. The skills involved are practical and achievable:

• Measuring
• Cutting
• Drilling
• Welding or arranging welding
• Basic fabrication
• Mechanical assembly
• Simple steering and brake setup
• Chain alignment
• Problem solving

A cyclekart is a great project for someone who enjoys making things and wants a hands-on mechanical hobby.

That said, safety still matters. Steering, braking, wheels, axles, and throttle return should all be treated seriously. A simple machine still needs to be built properly.

Are Cyclekarts Road Legal?

In Australia, cyclekarts are not road-registered vehicles nor can they be registered.

They are usually driven at private events, club drive days, displays, demonstration areas, or suitable private property. They are not generally intended for public roads.

Before building or driving a cyclekart, you should check the rules of your local club, event, property owner, and relevant authorities.

What Is the Point of a Cyclekart?

The point of a cyclekart is not just the finished machine. The build is a major part of the hobby.

Cyclekarts bring together:

• Vintage car inspiration
• Fabrication
• Mechanical problem solving
• Driving
• Community
• Creativity
• Affordable motorsport-style fun
• Positive Mental Health

For many builders, the real satisfaction comes from turning an idea into a working machine.

You start with steel, wheels, an engine, and a rough concept. Over time, it becomes something with personality. Something you built. Something you can drive.

That is hard to beat.

What Does a Cyclekart Look Like?

There is no single correct look.

A cyclekart might be inspired by:

• A 1920s Grand Prix car
• A 1930s sports car
• A pre-war hill climb special
• Speedway Midgets
• Early Formula 1
• A cyclecar
• A vintage speedway machine
• A local historic racing car
• A completely imaginary period-style design

Some have long bonnets and boat tails. Some are simple open-wheel specials. Some are polished and detailed, while others look rough, purposeful, and well-used.

The best cyclekarts usually have a strong sense of character.

How Much Does It Cost to Build a Cyclekart?

The cost can vary a lot depending on how much you make yourself, what parts you already have, and how detailed you want the finished kart to be. Open chequebook builds are not in the spirit of cyclekarting. Building them to a price is half the fun. 

The main costs usually include:

• Engine
• Wheels and tyres
• Axle and hubs
• Bearings
• Brakes
• Chain and sprockets
• Steel for the chassis
• Steering parts
• Body materials
• Fasteners and hardware
• Paint and finishing materials

A cyclekart can be kept fairly simple, or it can become a more detailed custom build. The good news is that you do not have to buy everything at once. Many builders collect parts over time and build in stages.

Why Are 25mm Axles Common?

A 25mm rear axle is a popular choice for many Australian cyclekart builds because it is strong enough for the job, easy to support with common bearings, and compatible with a range of useful parts.

A typical 25mm rear axle setup may include:

• 25mm keyed axle
• 25mm pillow block bearings
• 25mm wheel hubs
• Sprocket carrier
• Rear sprocket
• Brake disc carrier
• Shaft collars
• Key steel
• Spacers and fasteners

Choosing parts around a common axle size makes the build simpler and helps avoid compatibility problems later.

Is There a Cyclekart Community in Australia?

Yes.

Australia has a growing cyclekart community, with builders and enthusiasts in multiple states. The Cyclekart Club of Australia supports the hobby through events, displays, drive days, technical discussion, and community connection.

Cyclekart events are usually friendly, practical, and focused on participation rather than serious competition. For many people, the social side of the hobby is just as important as the driving.

It is a hobby built around helping each other, sharing ideas, and getting more interesting little machines out of sheds and onto the grass, track, or display field.

Is a Cyclekart a Good First Project?

A cyclekart can be a great first vehicle project if you are realistic about the work involved.

It is smaller and simpler than building a full-size car, but it still teaches many useful skills. You will learn about chassis layout, steering geometry, brakes, chain drive, wheel alignment, fabrication, and mechanical assembly.

It is also forgiving in the sense that there is no single perfect design. You can build something simple and improve it over time.

The best advice is to start with a practical plan, choose compatible parts, and avoid overcomplicating the first build.

Final Thoughts

A cyclekart is a small vintage-inspired car built for enjoyment, creativity, and hands-on mechanical fun.

It is not about big horsepower, high cost, or perfect replicas. It is about building something with character, learning as you go, and joining a community of people who enjoy simple machines.

Whether you are interested in fabrication, vintage cars, small engines, or just want a different kind of garage project, a cyclekart is a great way to get started.
