Part 2: the idea and donorbike
But ...i needed something with a loooong range. Reason is
that i need to prepare to get to my workshop in the Netherlands. It
is near a town called Monster. Really! So ...that is where the name
of the project came from.
At first i thought about using a Vectrix as donorbike and
fill it with batteries, but ...as a non-engineer i didn't like the
idea of trying to convert this complex Vectrix system into
something with a different set of batteries. So...i bought a Suzuki
Burgman 650, because i knew fromt he pictures from the bikeweb-site
that it has a very low frame.

I started to test different seat positions.
- Option 1: seated just in front of the fuel tank. It is a
very low seating, so it will create less frontal area, which
results in less drag. But ...i need to place the airfilter
somewhere else to give space for my legs. And i need to make a
proper foot rest system that still allows full steering of the
- Option 2: seated on top of the fuel tank. This is more
like the original driver position. I can keep the airfilter and i
might have the same low seating if i place the fuel tank behind or
in front of the driver. This option has lesser space behind the
driver, so ...less trunk.
- Option 3: seated on top of fuel tank but with a typical
recumbent seat angle. I really like that the entire back is
supported. It makes long rides less tiring for the lower back. But
...here it creates a new problem. Totally no more space behind the
driver and the need to make the steering system longer.
I prefer option 1 for its low seating, the ability to use the
original fuel tank, the fact that the drivers head is more forward
and so the highest point is more forward. This can help to get the
center of the side area more towards the front and ...i know from
Arnold Wagner, the designer of the Ecomobile, that this helps with
automatic countering of sidewinds.
