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!! Jerry Dycus.

Subject: Re: [EVDL] Sparrow alternate?
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?
