Monotrack Build Plans
These plans show how to build a motorized monotrack with only basic tools and materials, driven by a lightweight gasoline engine.
The monotrack bike’s core feature is the single recycled truck tire wrapped around its body. This unique machine has taken the concept of repurposing salvaged components to a whole new level. The tire, transformed into a tank tread, not only provides maximum grip but also allows for jaw-dropping wheelies and effortless stoppies.
The problem is, tank tracks—even for small diggers, snowmobiles, and so on—are pretty expensive. So for this project, the cut-down truck tire works really well from a cost perspective.
Tracked vehicles are cool, but can be quite complicated to build, so I planned it to be as simple to build as possible. That means ditching custom-machined parts like wheels and suspension systems. These were replaced with ten inexpensive 4.10/3.50-4 size wheels and axles mounted on a simple, but really strong, steel frame.
Imagine for a moment that you have the detailed building instructions to build this tracked machine out of things you’d find in your nearest junkyard.
The first step to start building this Monotrack is getting a used 295/80 R22.5 truck tire and removing its two sidewalls to make it softer and easier to slot into the frame.
The build plans include parts, material, and fastener lists, while the drawings feature clear 2D and 3D diagrams. Components are broken down into subassemblies to make manufacturing easy for the home builder.
You might have questions along the way, and when you do, I’ll be right here to help you through the build process.
