I prefer to hoof it (walk) around my property as I see more native wildlife
that way and Niki
The Wonder Dog and I get some much needed exercise to boot; but at times
it's impractical.
When I need to haul tools or get somewhere quick, I use a 125cc ATV (All Terrain
Vehicle) to zap around. It's nothing flash and probably wouldn't be the best
choice for a real working farm, but it does the job for me.
But I hate the noise - noise
pollution is severely underrated environmental issue, a pet peeve of mine
and I really don't like contributing to it. I chose a 4 stroke 125cc partly to
try and minimize the amount of noise generated; but it means I miss out on the
extra grunt of a bigger ATV.
Pollution is another major issue as most gas powered ATV's aren't really big on
emission control systems. I can't remember where I read the information, but
supposedly ATV's and dirt bikes in general crank out 6x the emissions (cc
for cc) as your average family car.
Overall, ATV's aren't all that environmentally friendly - especially the way
some recreational riders use them; but they are a very valuable tool on a farm.
A solution is the electric ATV. These have been available for a while, but when
I last looked a couple of years ago they were around the USD $30,000 mark and
were still quite limited in what they could do in terms of real work.
I was looking at electric ATV's again today and noticed things have really
changed. The Chinese are starting to produce very cheap electric ATV's, but the
quality is probably a bit iffy at this stage.
Then I came across the American-built E-Force
ATV and started drooling. The makers (EVS - Electric Vehicle Systems) say
the E-Forces's Torque On Demand electric drive system has more than three times
the torque of similar sized gas-powered ATVs.

EVS E-Force Electric ATV
As to what "similar" means, I really don't know much
about ATV's or engines generally, but I'm guessing based on the horsepower, the
E-Force ATV would be the equivalent to a 300cc gas engine.
The Torque On Demand is controlled from the ATV's digital dashboard. There's
what they refer to as the "grannie" mode for just cruising along, then
torque levels can be nudged up incrementally for more serious work (or ahem,
"fun").
Powered by a 72 volt brush DC motor and producing up to 28HP, the E-Force stores
charge in 6 x 12V-50AH SLA AGM deep
cycle batteries. It takes only 6 hours to fully charge from mains power and
I guess it could be rigged to charge via solar
panels for a truly clean ride; although the charge times would be far longer
using just a couple of panels.
Bear in mind just because a vehicle is electric, it doesn't make it green - that
depends on how the power you use to recharge it is sourced; e.g coal
fired power generation is pretty filthy and even so called "clean
coal" isn't as clean as renewable
energy. However, with many electricity providers now offering green
power options, you can get a more environmentally friendly charge even if
you don't have a solar
power system.
The E-Force has a maximum top speed of 35 miles per hour and a maximum range of
25 miles - so more suited to small farms. An interesting add-on for the E-Force
is a generator tray. With a generator mounted on the back, this can provide
power in the field for tools and also act as a charger for the ATV if your
battery runs out in the middle of a paddock.
It can carry 66 lbs front on the front rack and 99 lbs on the rear. Towing
capacity is a very impressive 1,000 lbs.
Oh, and judging by the video on the manufacturer's site, it's incredibly quiet!
Unlike my current ATV which I can push if need be (it's under 200 lbs), the
E-Force is very heavy - around 824 lbs. Based on my own deep cycle battery for
my mobile solar power system, I'm guessing the batteries in the E-Force account
for around 150 - 200 lbs of that weight. It's a bit of a concern if it should
roll on you and it also means a lot of the juice is spent on hauling its own
batteries, but the extra weight can be very useful in some applications and
would help with stability.
Given the current focus on developing batteries for electric cars, maybe it
won't be too long before we'll see lightweight batteries for ATV's as well.
The cost? I've seen the E-Force for as low as USD $6,600. That's still far from
cheap, but a big drop from the $30,000 I had seen for similar ATV's not so long
ago and is getting very close to the price of a good quality gas-powered ATV in
the 300 - 400 cc range. If it's bought for work purposes, then it's a tax
deductible item.
Update: December 31, 2009
Here's another Electric ATV I came across, the Zap Dude:

Zap Dude Electric ATV
The Zap
Dude has fairly similar range and speed as the E-Force according to Zap, but
has a 48V permanent-magnet Brush DC Motor and a 65aH Absorbed Glass Matt (AGM) Lead Acid battery.
While that means a far lighter ATV, it's also far less storage capacity - so how
it achieves the same sort range and speed I have no idea - I think the key term
here is "up to". Anyway, it's another good looking electric ATV
that seems to be more than just a show-pony and at USD $5,495, will be over a
thousand bucks less than the E-Force when it becomes available in January.
Do you own an electric ATV; an E-Force or another type? I would
be interested in hearing your experiences, recommended models etc. Please add
your reviews, feedback and comments below.
