Because the rider has to input the power. In order for even a 100%
efficient system to be able to get you home, charged solely form the
on-board dynamo, and assuming you use regenerative braking, I still
can't imagine that you'd be able to do it without either taking far
too long to charge, or requiring the rider to work around 50% harder
while pedalling - in which case the device would create its own
necessity...

I am reminded of the design phase of the Mosquito bomber during WWII.
The Air Ministry insisted that all bombers must have a mid-upper
turret, so de Havilland arranged some mock dogfights between the
Mosquito and a Spitfire, with and without a mockup turret. Without
the turret the Mossie could outrun, out-climb and out-turn the
Spitfire. With the turret, the Spitfire caught it easily. Thus
proving that the only way a Mosquito would need a turret was if you
put a turret on it :-)

And a different version of history too!

The bicycle was invented by two Frenchmen, Pierre and Ernest Michaux
(father and son). This was for a bicycle with pedal and cranks (1861).

Baron Karl Drais von Sauerbronn, a German, invented the wooden machine
with two wheels that you propelled with your feet, and could steer (1818).

Prior to that, there was a non-steerable machine, invented in 1790 by
Comte Mede de Sivrac (French).

The Penny Farthing was invented in 1871 by British engineer, James Starley.

I think that a Brit did invent the bicycle helmet, even though some
people claim that it was invented by Herman Roth and Charles Lombard in
1960.

Well, they invented the pedal and cranks anyway. The British claim is
the safety bicycle, invented by John Kemp Starley and William Sutton
in 1885. Actually a development of the Lawson bicyclette, I think,
itself a development of the Bates "Flying Dutchman".

As with so many inventions the man with his name on the patent may
well not be the originator of the idea...

I was thinking of charging going down those sometimes tedious
long slow downhills, and to some extent braking duty coming
up to a known slow down point. Putting enough charge in the
it could be used for something else, not a whole electric mo-ped.
Just an idea.
