DIY Reverse Trike Plans: An In-Depth Guide to Building Your Own Three-Wheeled Vehicle
Introduction to DIY Reverse Trike Plans
DIY reverse trike plans have gained popularity among automotive enthusiasts and hobbyists who seek to combine the thrill of motorcycling with the stability and comfort of a car. A reverse trike, also known as a tadpole trike, features two wheels at the front and a single wheel at the rear, providing excellent balance, maneuverability, and a unique aesthetic appeal. Building your own reverse trike can be a rewarding project that allows customization, cost savings, and the satisfaction of creating a functional vehicle from scratch or kit components. In this comprehensive guide, we will explore the essential aspects of planning, designing, sourcing parts, and constructing your own reverse trike.
Understanding the Basics of Reverse Trike Design
What Is a Reverse Trike?
A reverse trike is a three-wheeled vehicle with two wheels positioned at the front and one at the back. This configuration differs from traditional tricycles or three-wheel cars, offering a lower center of gravity, better handling, and a sporty appearance. Reverse trikes are popular for recreational use, commuting, and even racing.
Advantages of Building a Reverse Trike
- Enhanced stability and safety compared to traditional motorcycles
- Lower manufacturing and customization costs
- Unique aesthetic and personal design expression
- Potential for high-performance modifications
- Learning experience in engineering and fabrication
Key Components of a Reverse Trike
To successfully build a reverse trike, understanding its main components is essential:
- Chassis/frame: The structural backbone that supports all other parts
- Front suspension and steering: Responsible for handling and ride comfort
- Rear drivetrain: Including the engine, transmission, and rear wheel assembly
- Wheels and tires: Sized appropriately for stability and performance
- Seats and cockpit: For driver comfort and control
- Electrical system: Lighting, ignition, instrumentation
Planning Your DIY Reverse Trike Project
Setting Your Goals and Budget
Before diving into plans and parts, define your objectives:
- Will this be a recreational vehicle, a commuter, or a racing trike?
- What performance specifications are desired?
- How much are you willing to spend?
- What skills and tools do you possess?
A clear goal helps determine the complexity of your build and guides the selection of parts and design.
Research and Inspiration
Gather inspiration from existing reverse trikes—both commercial models and DIY projects online. Study their design features, materials, and performance characteristics. Watch videos, join forums, and read build logs to understand common challenges and innovative solutions.
Design Considerations
- Weight distribution: Aim for balanced weight for stability and handling
- Aerodynamics: Consider streamlining for efficiency and aesthetics
- Safety features: Incorporate roll bars, seat belts, and crash zones
- Legal compliance: Ensure your build meets local vehicle regulations
- Accessibility and ease of maintenance: Design for straightforward repairs and upgrades
Creating Your DIY Reverse Trike Plans
Sketching and CAD Modeling
Start with detailed sketches of your envisioned trike. Use computer-aided design (CAD) software for precision:
- Draw the chassis layout
- Plan suspension geometry
- Position key components
- Simulate weight distribution and handling
CAD modeling allows you to visualize your build, identify potential issues, and make modifications before fabrication.
Materials Selection
Choose appropriate materials based on strength, weight, and cost:
- Frame: Steel (e.g., chromoly or mild steel) or aluminum for durability and weight savings
- Suspension components: Steel or aluminum parts, sourced from automotive or motorcycle suppliers
- Body panels: Fiberglass, carbon fiber, or lightweight plastics
- Seats and interior: Automotive-grade upholstery or custom fabrications
Detailed Plans and Blueprints
Develop comprehensive plans that include:
- Frame dimensions and joint details
- Suspension mounting points
- Engine placement and drivetrain routing
- Wiring diagrams for electrical systems
- Mounting locations for seats, gauges, and controls
Having detailed blueprints ensures clarity during construction and helps communicate your design to suppliers or fabricators if needed.
Sourcing Parts and Materials
Engine and Drivetrain Options
Decide whether to:
- Use a small motorcycle engine (e.g., 250cc to 1000cc)
- Repurpose an engine from a donor vehicle
- Opt for electric motors if aiming for an electric reverse trike
Ensure compatibility with your chassis and power requirements.
Suspension and Steering Components
Sources include:
- Motorcycle front suspension parts
- Automotive salvage yards for used parts
- Aftermarket suppliers offering custom suspension kits
Wheels, Tires, and Brakes
Select wheels and tires that balance performance and safety. Larger front tires improve grip and steering response, while rear tires should match the power output.
Chassis and Structural Materials
Purchase steel tubing, aluminum plates, or pre-fabricated chassis kits. Ensure materials meet safety and durability standards.
Electrical and Accessories
Gather:
- Wiring harnesses
- Lighting
- Instrumentation
- Battery and electrical components
Building Your Reverse Trike: Step-by-Step Process
Preparing the Workspace
Set up a spacious, well-ventilated workshop with:
- Welding equipment
- Hand tools (wrenches, screwdrivers, pliers)
- Power tools (grinders, drills)
- Measuring tools (calipers, tape measure)
- Safety gear (gloves, goggles, masks)
Fabricating the Frame
- Cut and weld steel or aluminum tubes according to your blueprints
- Ensure proper joint alignment and weld quality
- Add mounting points for suspension, engine, and body panels
Installing Suspension and Steering
- Mount front suspension components
- Install steering linkage and test for smooth operation
- Attach rear drivetrain components
Assembling the Drivetrain
- Mount the engine and transmission
- Connect the drivetrain to the rear wheel
- Install the exhaust system and cooling components as needed
Electrical Wiring and Controls
- Connect wiring harnesses
- Install ignition, lights, and instrumentation
- Test electrical systems thoroughly
Final Assembly and Testing
- Mount seats and interior components
- Secure all fasteners and check for safety
- Conduct test drives in controlled environments
- Adjust suspension and steering settings for optimal handling
Legal Considerations and Registration
Ensure your DIY reverse trike complies with local vehicle regulations:
- Obtain necessary permits and inspections
- Register the vehicle with appropriate authorities
- Install required safety features (lights, mirrors, reflectors)
Understanding legal requirements prevents future complications and ensures safe operation.
Tips and Best Practices for Successful DIY Reverse Trike Projects
