Step 1: Short Video - Synthetising
We made this vehicule for the "ecolo parade 2003" in Paris, the green party. This is afor 4 pedalibng people, and 1 driving.
Step 2: Soldering Prototype
this is the making of the prototype suspended while soldering.
Step 3: The First Prototype, 2 Front Wheels
we wanted to make it stable and strong so the first prototype had two front forks. It wasn't a good idea ... the original normal bike axes weren't strong enough ...
Step 4: Prototype, Back
The handles for the engine-pedaling people are missing.
A wheel was missing ... the structure was too rigid so most of the time only 2 wheel were touching the road _ so only two people pedaling for real !
This prototype was so dangerous, it had no brake, we destroyed a police car in the midle of the night ...
Step 5: Final Prototype !
finally we used this one for the protest ! It was working so perfectly !
Step 6: Little Black Kddies Squatting My Bike
The only we had was the popularity of the bike !!!!we ended being 10 people on the bike at the same time ... we really had to consider this ... hehe !
Step 7: Look at the Video ! It Says Everything !
