Oh, indeed, and there is no question that different transmissions have
different efficiencies (and why a bicycle has 21 gears when it only
(typically) has a top speed of 20 mph .. it's because the 'engine' is
so low powered and has a restricted rev range?) 'and' that running IC
(and other) engines at specific rev ranges / temperatures allows
better efficiencies.

However, I believe, with all of the above, we are still 'w a y' off
them providing much of an avantage, compared with the better end of
todays more traditional offerings .. all things considered?

There is much ill-informed botty talk above. A hell of a lot of it.

Bless .. Ok, I know your tricycle has 'direct drive' but you must
accept (maybe once the medication has worn off) there is a real world
out there. One that hasn't yet discovered perpetual motion or 130 mpg
batteries .. ;-)

All the very best with your recovery ..
