Crazy Bike

Experience drifting on a cart is entertaining, but drifting on a bike offers an even more thrilling experience! In my youth, I raced pit bikes frequently, which left a lasting impression on me. This project is constantly evolving and updated daily. Day 1: A test frame was created using the new ST7 3D sketch feature. Day 2: Added a mountain bike hydraulic brake for easy burnouts; studied battery positioning while considering center of mass. Day 3: The frame and fork were updated, electronic placement was studied (using bluesurf primarily), and the initial fender design was created. Day 4: Shortened the frame, added battery support, and updated the motor support. A preliminary seat design was also sketched out (again, using bluesurf). Day 5: Weldments were added to the frame, and attempts were made to render the welds with a specific bumpmap image. Unfortunately, this process was slower than anticipated. Day 6: Foot pegs were added, and the caliper was edited for better compatibility with the fork. Day 7: The caliper was perfected (before and after comparisons can be viewed), the motor speed control dial was edited, and tire patterns were changed. Day 8: Main power switches and recharging plugs were added, along with a personalized "GRAB ME" plate. Day 9: The bottom part to partially enclose the battery zone was added, and the front fender was refined for a smoother appearance. Day 10: Five distinct "style" bikes were created using KeyShot's pattern tool: Solid Edge, KeyShot, GrabCad, Gum, and Flame. Day 11: A "Combat Ready" style bike was designed with a black mannequin performing a burnout (smoke not included). Day 12: A promotional video was created. Day 13: The seat was updated based on Kenneth Wong's suggestions. Day 14: A rear light and drive by wire cable were added, necessitating electronic repositioning. The initial inspiration for this project came from an ASM Solid Edge file that contained the "Blue Prints" for a pocket bike (http://www.diygokarts.com/bike-plans/pocket-bike-design.html). Synchronous editing was used to modify various parts, such as the Magura disc brake system and the stem, handlebar, and grips from a Freeride MTB. The heart of the Crazy Bike lies in its electronic components, specifically the Crazy Processor Unit (CPU), which processes data from an onboard inclinometer and drive by wire dial to control power output to the rear wheel. This system ensures safe wheelies and allows for precise acceleration and braking through the drive by wire dial. The rear brake functions as both a brake and a charger, while the powerful hydraulic front brake from the mountain bike market provides controlled burnouts.
