An ATV combines all the negative handling characteristics of a car
with all the negative handling characteristics of a motorcycle.

But it is fun to drive.

This ATV is a real camera car with all the mounts und features you
need.

Because of the very very loud combustion engine it was basically
used for shooting stunts. But also there the emissions and noises
are very irritating.

But one lucky day, the motor output shaft was broken. And so the
eGrizzly story could begin...

First major challenge was that there were no other experience on
this kind of conversion. Will the motor be able to accelerate this
weight in direct drive and how fast..? How heavy will it be with
"some" range..?

Honestly, I had rejected the project again, because I thought that
it does not work. I already had the old engine on the hook to
reinstall it to repair the broken shaft when something said to me:
STOP.

I went from step to step to try out the possibilities. And I am still
on the way...

Top speed: 75 mph. More I have not yet dared...

Second top speed test today. But the chassis limit is already
overstepped at this speed.

The next version will have a gear reduction.
