Crazy Bike

grabcad

Drift on cart is great but drift on a bike is even more ! I did race a lot on pit bikes when I was a youngster so bikes are always in my mind. Still a work in progress, I will update it daily. Day 1: Created a test frame using the new ST7 3D sketch feature. Day 2: Added front brake (moutain bike hidraulic brake), should make easy to do burnouts !; started to study position for battery. Will have to check about center of mass. Day 3: Frame and Fork updated, electronic positioned, first fender style study (bluesurf mainly used). Day 4: Shorter frame, added battery support. Motor support updated. First study of the seat (bluesurf mainly used). Day 5: Added weldments on frame, using the weldment environment in SE found it slower than what I remembered. trying to render the welds with a specific bumbmap image (not happy with the result yet). Day 6: Added feet pegs and edited the caliper (was fun to edit an imported model with syncrhonous technology) now fixed with the fork. Day 7: Finished to edit the caliper (see the after and before comparison pictures, was good fun to use synch for editing), added the "dial" to control motor speed (still editing it). Chenged the tire pattern. Day 8: Added main power switch and recharging plug, added a personalized "GRAB ME" plate. Day 9: Added the bottom part to partially close the battery zone. Remade the front fender for a better smooth look (bluesurf used alot and a bluedot too). *** time to play with renders now *** Day 10: created 5 "style" bikes using the keyshot new pattern tool. Styles are: Solid Edge, KeyShot, GrabCad, Gum and Flame. Day 11: created a new "Combat ready" style with a black manequin standing in a burnout position. (didn't figure out how to render the smoke ). Day 12: created a promo video Day 13: updated seat as suggested by Kenneth Wong, thanks ! Day 14: added rear light and drive by wire cable: electronic repositioned. I did upload an image that made me first thinking of this project. Inside the main ASM Solid Edge file there is a couple of sketches containing the "Blue Prints" of this pit bike. All started from there. ( http://www.diygokarts.com/bike-plans/pocket-bike-design.html ) Magura disc brake system downloaded from Magura MT9 Hydraulic Disk Brake Concept then syncronous edited. Razor style disc made by me. Stem, handle bar and grips are parts of this project syncronous edited by me: Freeride MTB Wish to have more time to spend with this great tools I'm getting addicted on them. ****** Final 3D model uploaded, download the V2 RAR archive and overwrite previous one ****** The core of Crazy Bike is in its elettronics. The Crazy Processor Unit "("CPU" in short) receive data from the on board inclinometer and from the drive by wire dial; process it hundres of time per second and instantly decide how much power transmit to the rear wheel. It's never been that safe to do terrific wheelie. With the drive by wire dial you can both accelerate and brake, push to accelerate and pull to brake. Rear brake is activated by request power from the electric motor and acting like a battery charger to save energy. Front brake is a powerful hydraulic brake that comes from the mountain bike market; use it to clamp the front wheel to the ground, balance your weight on the front wheel and do spectacular burn-outs again safety controlled by the CPU.
