I am a big fan of alternative transportation, and I believe it could be
very practical and cost efficient to promote the use of both bikes and
light electric vehicles... but I think it is a very bad idea to combine
these into one machine (ie hybrid).
Enclosed human powered vehicle = instant sweatbox. Very few people wish
to
become a sweaty mess or work out very hard when commuting or running
errands. The enclosure also adds a lot of weight.
Practical speed for average pedal powered commuter ~ 10mph (not 40mph).
Practical performance parameters for a light electric (enclosed)
vehicle: 250lbs, 30mph cruising speed (40mph max), 30mile range,
<$2,000. Such a car would be adequate for the majority of trips that
6,000lb SUVs are currently making. The car would have ~2kW motor so
100W or so of pedal power that could be added wouldn't amount to
much... and wouldn't be worth the added complexity.
There aren't any technological issues... these things are very simple
and easily designed and built with off the shelf parts.
There are plenty of electric scooters on the market right now. Probably
one of the best is the Emax:

The biggest obstacle to people wanting to use bikes or light electric
vehicles is the lack of a safe place to ride/drive them. Very few wish
to risk their lives under the wheels of all the impatient SUVs and
trucks that they are forced to share the roads with. Until this issue
is seriously addressed by restricting where the large vehicles can
drive, and allowing the smaller vehicles the right-of-way, then I have
little hope for positive change.
