How to sketch a Bike ?!
I asked myself ...

Generaly speaking, when i ask myself something, i try to do it ...
As a starting point, I worked on the general shape ... not visible here, b'cause it is a big deformed kind of spherical thing, a kind of navished triple bubble combination, stretched on Z axe, etc. deformed , etc.

So, here you have 4 variations that are based on sketching sessions, to define :
- a chassis concept, a general choper form w/various positions possibilities ...
- a base for protection necessary part
- base for realistic-ism action figuration like rotation of the front wheel part, and dependencies, parents parts ...
- classical parts, as oil compartment, doubled, for a "Traveler" edition, for road trips representations, etc.

AND, some parts that can give another realistic touch, like :
- wire
- tube
- bumpers
- brake ctrl
- glasses/mirrors
- lights
- stop/parking under chassis parts
...

i KNOW ! there is any Lot of work to engage to go further ...

But i did not want YOU to think I was away !!! I'm here ...

PS :
I thought it could be ok to try to compose ONE shape that could help producing 3 different vehicules :
A MotorBike
but also :
a JETSKY
a SNOW-BIKE

at ZE same time Think about that when you watch at the general forms ... please !

be indulgent ! it's just a second hand bike !
