2 revolutionary Javanese bicycle concepts!!!

2 Technological Revolutionary Javanese Bicycle Concepts. 

Which one is it? 

(1), (2) or combination (1)+(2) ? :)))

(1) Double Equipment Bicycle Concept. (DEC)

DEC concept is used by Shipbuilding and Spaceships Construction Industries. (Like NASA).

You simply double all important equipment. All crucial parts. If one part is down. Broken. Lost. Stop working. Whatever. You simply switch on the spare one. And in the meantime you may repair the broken part. 

Just discovered that this DEC concept is also largely used in East Java. In Human Bicycle transportation. 

Just discovered this revolutionary DEC concept also used in Java

:))))

(2) Uphill/Downhill bicycle concept. 

It can be also another revolutionary concept. Uphill / downhill bicycle. 

All bikers know that is impossible to have a perfect Uphill/Downhill bicycle.

For uphill u need the lightest possible hard trail (only front suspension or no suspension at all).

For downhill the opposite. Heavy. Solid. Stable. Full suspension (front and rear). Almost like motocross bike. 

Impossible to combine. The only way is to have 2 different bikes. 1 for uphill. And another 1 for downhill. 

So on the picture u see the prototype of the first in the world  Uphill/Downhill bicycle Concept! 

Bravo Indonesia! Bravo Java!
