This is my latest plan for the TriGo

I am searching for a good design to build a velomobile suitable to evervday use with two seats.

The TriGo must:

• Be light weight, because it goes with human power.
  The light weight construction should not lead to less stability and expensive high tech materials should not be used. Therefore I integrated as much functions as possible into the main frame, which otherwise had to be build with the use of extra material.
  The fairing should not increase the weight too much. This should be possible with my Elastic-Design.
• Be save for using it in normal traffic.
  The seat is integrated into the main frame tubes. This allows a deep position of the seat. A safety belt can be attached to the 'oversized' back-tube of the seat.
  The back of the seat reaches above the head as an overroll bar. The tubes next to the riders are a kind of stiff side panel to protect the riders from a side impact.
  The main frame tubes protect the riders from frontal impacts. In the very front there is a bumper.
  There are no hard things in front of the riders.
  
• Have a big space for transportation with security against theft. A lockable aluminum box is a good idea.
• Be a tandem, but suitable to ride with one rider. Both riders are sitting next to each others for easy communication.
• Have protection against any weather. A half fairing at the front side and a fairing out of fabric, that can be tilted up in bad weather (cabriolet).
• Be able to ride on every street including bumpy roads and mountains. Suspension on all wheels and multiple gears are necessary. Its total width must be reduced to one meter (39") to be compatible with cyclist-infrastructure.
• Be fast. An aerodynamically faired HPV is fast without a motor.
• Be easy to repair and maintain. Parts, that often are worn out must be accessable all over in the world. No high tech parts are used. For example BMX-parts are easy to access.
• Security against theft. A build in transmitter and an electric security system is a good idea.

These are my plans. I will build it soon and then upload my construction plans.
