The book ventures into basic electronics, which distinguishes it from standard bicycle repair manuals.
This is arguably the most popular section of the book, focusing on the "Kustom Kulture" aesthetic of elongated front ends and relaxed riding positions.
First, let’s demystify the source. This is not a novel or a history book. It is a project-based DIY manual written by Brad Graham and Kathy McGowan (the legendary team behind Atomic Zombie). Published by McGraw-Hill/TAB Electronics, it is part of the famous Evil Genius series—known for turning complex engineering into accessible, slightly mischievous weekend builds.
Unlike polished manufacturer manuals, this book embraces the "mad scientist" ethos. It assumes you have basic tools (welder, grinder, drill press) and a willingness to fail spectacularly before succeeding. The PDF version has become especially popular because makers can zoom in on welding diagrams, print templates directly, and keep a digital copy smudge-free on a tablet next to the bench grinder.
This section focuses on taking standard bicycles and altering them for performance, comfort, or style.
You might ask: Why specifically the PDF? Why not buy the hardcover?
Three reasons:
A concise, safe, and practical project roadmap for building and modifying bikes, scooters, and choppers inspired by the "Evil Genius" DIY style: creative, budget-minded, and mechanically focused. Emphasis on safety, legality, and stepwise learning.
Using two discarded mountain bike frames, the book details how to cut, stretch, and re-weld the top tube to create a 10-foot-long chopper. The "Evil Genius" twist? No alignment table required—just a string level and a concrete floor.
A three-wheeled beast where the rear wheels are wrapped in PVC pipe for drifting. The PDF includes a parts list sourced entirely from Home Depot and a dead treadmill motor.
