First road test
Perfect..
100km/h with GPS app

With 200a setting on controller.

Next step
New tyre, dashboard and cosmetic
 
Small update
The new engine will be a Me1507 with a sevcon 80v350a (unless I find a size 6)

I also change the voltage for nominal 96vdc I will install two 48v 87ah packs
They will be able to delivered 200a without too much overheating.

For that I have to move the engine down.
But it adds a technical problem: I have to install a system of double transmission or to operate the chain in a "original" way1567092122744-810x583.jpg

First option:
First stage with belt
And second stage with chain

Second option
Only one chain but the upper are free sprocket
