Hi Bill and All, As you know there is a solution to
long range MCs and it is aerodynamics. As the E Tracer, others have showed.
By turning the brick into a clean airflow you can double range
at speed for about 15lbs of plastic in the form of a real aero fairing and most
any E MC. It is far cheaper, lighter than more batteries and
amazes me EV MC companies, people have put them on saving $1,000s in battery.
The only thing keeping me back from building a 200 mile range aero
2 wheel streamliner is 4-5 Tesla battery modules as my Volt modules are too
heavy, take too much space, can't be used. Though putting a full
aero body on my newest E Woody trike MC that does have the room for Volt
modules and can put up to 300 miles worth, likely just 180 miles though. Not
only room for more batteries but enough to lay down, sleep in for when my back
gives out. I'm putting 2 K91 motors from a Crown Pallet Jack in
and chain driven to a golf cart transaxle with 1 to move the trike and the
second to tow an aero trailer at 65mph long distance power.
The GC motor didn't have the power, top speed only 45mph and was too much
unsprung weight giving a harsh ride. By putting the motors on the 'firewall'
it gives me the gearing, power I need at less unsprung weight, more comfort.
My other news is just got a near free 26' Chrysler sailboat that a
marina seized for non payment but no one bid. I'm turning it into
a solar boat to live on as I move to St Pete. Luckily I already have lead
batteries from a lead to lithium conversion I did and some free solar panels,
other things I'll have little money in it. You can now buy a well
founded liveaboard size sailboat in Florida ready to sail for under $3k and
ones like mine that need work, much, much less. Many have bad
motors ready to switch to E drive and if you anchor in a tidal current, can
recharge your batteries with it. Look on craigslist for them.

This is the main problem with typical motorcycles. They are
basically a brick, aerodynamically. This is compounded by the lack of
space and load carrying ability for a decent battery pack. Very
difficult to make an electric bike with decent range.
