It looks good so far!
Around here a Serial Hybrid makes sense: (preferably with a direct overdrive)
Power's more off than on in 'The New South Africa' so a Serial Hybrid means you can bring the 'lights' home with you.
I think a 20 kw efficient motorbike engine turning a good PM alternator is enough, if you have good regen:
MPPT-Supercaps-MPPT-battery:
Supercaps to absorb the high braking amps the battery cant take.
Then the 1st MPPT should get the slow speed/low rpm/too low voltage braking power into the caps or battery.
MPPT from the caps to the battery should get all the 'too low normally' voltage out of the caps and into the the long term storage battery.
Naturally, if the caps still have the voltage when you floor it at a green light etc, the (Max) power should/could come from them direct!
Errr.... OK I'll shut up now!
