Whether you're building a "Frankenbike" for a local parade or an electric scooter for a silent commute, this guide remains the definitive manual for those who prefer their projects with a side of "mad scientist" flair.
If you are looking for community help, alternative build diagrams, or specific component configurations, the authors run an extensive hub of custom-built transportation blueprints and build forums directly via AtomicZombie.
How to cut, bend, and weld metal safely and accurately.
To give you a taste, let’s look at one iconic project: Bike- Scooter- and Chopper Projects for the Evil Genius.pdf
A favorite among urban "bicycle insurgents," the tall bike is created by welding one bicycle frame on top of another. It’s a lesson in balance, structural integrity, and how to survive a red light when your feet are six feet off the ground. 4. Motorized Friction-Drive Bikes
Bike, Scooter, and Chopper Projects for the Evil Genius by Brad Graham and Kathy McGowan is a hands-on DIY guide for transforming standard bicycles and discarded parts into custom, high-attitude vehicles. It focuses on "chopping" (modifying frames) and building unique rides like electric scooters, recumbent trikes, and tall bikes using basic tools and a pragmatic "garage hacker" approach. Key Projects Featured in the Book
Any builder utilizing this PDF should treat it as a conceptual guide rather than a rigid bible. Modern standards for welding penetration and battery safety (specifically regarding Lithium-ion chemistry, which has evolved since the book's publication) should be rigorously applied. Whether you're building a "Frankenbike" for a local
The designs are intended to be modified, mixed, and combined, enabling builders to create hundreds of unique vehicles 1.2.1.
Breathing new life into old bicycle frames, lawnmower engines, and scrap steel.
This project challenges traditional bike design by placing the drivetrain on the front wheel, providing a relaxed, feet-first riding position that is both comfortable and efficient. 4. Cargo and Utility Bikes To give you a taste, let’s look at

3. Chapter 3: Rebel Yell — Making a Real Chopper 4. Chapter 4: Sparky — An Electric Mini Chopper
Note: The book also includes foundational chapters on building your own chopper from scratch and converting a standard bicycle into an "Electric Mule" or a "Stealth Electrification" project [12†L7-L14].
Ideal for beginners, these projects teach the fundamentals of frame modification, steering geometry, and braking systems.
