When I made comments about 3-wheeled ATVs I did not think about the low CG
with the batteries on an electric vehicle. It will take some convincing,
but I would love to give some trikes a try.
I'm still thinking about putting a trike kit on my Sportster, but that
would still be an ICE. I'm actually considering selling my Harley and
getting something like an electric Vespa, even though that would be
sacrilege.

Hi Bobby and All,
3wh vehicles , just like 4wh ones, handle as well as they
are designed to. I've done about 13 of them over the yrs and what matters
is how low and where you put the CG which should be 33% inside of the 2
wheel axle.
You can make a 2 front wheel/RT, one that will scrub off the
tire or break the suspension before it'll roll with it's EV batteries low
and correctly placed, between the front wheels.
Or you can make it with a high aft CG and it'll easily roll
over.
On the Sparrow, it's handling is like big SUV, Van, safe
driven within reason.
Even my EV trike pickups far out handle all ICE trikes and
barely has to slow for cornering, taking them as well as most cars.
Though if I want best performance, go with the 2 front wheels
which properly set up should do autocross very well..
Because of the need for low correctly placed CG, makes EVs and
natural partners. Now add lightweight and if aero, very long range on a
small pack, easily getting 200 miles with a 20kwh pack.
And speaking of long range trikes, my newest EV trike subcar is
in chassis but legal form, on the road testing out systems before making
it's aero body.
Right now it looks like my EV trike pickups.
For those new, it is a large MC front end, a wood/epoxy
chassis, body with a hot rodded golfcart rear end and Volt EV lithium
battery modules.
Having a money crunch again I went back to a contactor
controller , 3speed with turbo/field weakening it's getting along well at
45 mph. I can probable go faster but it's only a 2.2hp rated motor!! And
fast enough for me so I'll leave it there for now.
I thought making he trailing arm suspension in the rear from
the stiff leaf springs but turns out I was very wrong. Apparently when I
built the previous ones by using alum rectangular 1x3'' make a anti roll
bar effect is why it stayed so flat it turns. With the Leaf spring ones
it would just lean one way or the other, usually the way you didn't want.
I pumped the air hocks up rather high so when I hit my 2nd
speed, the rear reared up surprising the heck out of me. So I lowered the
rear and most of it went away.
Just have a 4kw Volt EV module in now for testing with a
large 12vdc lead to balance it for 12vdc supply.
I'm using the FreedomEVs Prius replacement tires and
lightweight mags looks better and why I'm getting 10 mph more as my last
one it seems as battery voltage, motor, transaxle models
are all the same.
As I get it more reliable, I'll take the Battery out of my
present EV trike pickup giving me 8kwh and likely 100-120 mile
range. Most of mine run between 60-80wthr/mile with bad aero. We'll see
soon what my new one gets.
Just got my MPJA Wthr meter, good for 100 vdc and 400amps or so
yesterday so I'll know soon what a not aero version does.. I expect my
aero cabin version to use about the same at 60mph as the not aero at 45mph.
I'll rebuild my present one as an aero cabin it was suppose to
be the first time, with a much larger motor, chain driving the GC transaxle
so it can do 65mph and tow an aero, lightweight trailer long distance, up
to 250 miles on a charge.
And amazingly how low cost these are as I'll only have about
$800-$1200 in each one. I get my Volt modules cheap as I sell them for
$150/kwh.
I need to finish waterproofing it/epoxy coating, so it'll stay
nice looking and we seem to be in a tropical storm like system here for 5
days in Tampa. So good I built that shop, reason for low cash flow, to
work in as the rainy season is here early!!

When ATVs were first introduced as 3-wheelers I had one, but did not keep
it for long. 3-wheelers are an accident waiting to happen. With 2 wheels in
the front these car/motorcycle combinations may be safe, but it would take
a lot to convince me. Has anyone on the EVDL actually driven one of these
things and gone around a corner at highway speed?
