Given a "level
playing field" an electric bike or motorcycle will win over
a vehicle with an internal combustion engine in almost every
concievable way.
What are the advantages of Electric
Bikes and Motorcycles? All electric vehicles produce zero
emissions at their point of use.An electric motor is, on
average, 400% to 600% more efficient than an internal
combustion engine.
Even when charged by electricity
created from non renewable fuel sources like oil or coal and
electric vehicle, per mile, uses one-half the fossil-fuel
resources an internal combustion engine consumes. In this
"fossil fuel " charged case, the electric vehicle produces
only 5% to 10% of the emissions of an internal combustion
engine per mile traveled. All of the electric vehicles
emissions occur at a oil- or coal-fueled power plant, which
runs 400% to 500% more efficiently than an ICE and scrubs
its own exhaust. Electric vehicles can use electricity from
anywhere, including sustainable energy resources (wind and
sun). EVs are simple, silent, and affordable to
operate.
Electric vehicles are also very
efficient. They have to be. A pound of battery has 1/100
of the energy of a pound of gasoline. On average, a 30 mpg
internal combuston vehicle uses only 5% to 10% of the energy
of its fuel, whereas an electric vehicle converts 70% to 80%
of the battery's pack into propulsion, for the same
mile.
Quiet - Lack of noise is
also an advantage of getting an electric vehicle. Because
motor vehicles have combustion motors, they tend to be loud
and obnoxious. On the other hand, electric vehicles do not
have this combustion motor ; thus, they are noticeable
quieter.
The world is more than ready for
electric vehicles. In fact, electric motors are used
everywhere. Electric propulsion is not a new technology. The
modern locomotive is diesel-electric; its diesel
engine-generator supplies the electricity to power the
electric motor drivetrain. Electric motors also power
elevators, industrial assembly lines, ventilation and
air-conditioning units, refrigerators, blow dryers, washers
and dryers, computers and printers, CD players and autotape
decks, and pumps. Ironically, an electric motor is also
needed to start an automobile's engine. Wherever silent,
efficient, reliable service is needed, you will find an
electric motor at work.
Disadvantages of Gas powered
Vehicles.
Unlike electric vehicles, motor
vehicles generate more air pollution than any other
human-made machine. This air pollution, or toxic mixture of
chemicals released be motor vehicles, is recognized as a
major health hazard. According to the American Lung
Association, this air pollution kills between 60,000 people
and 120,000 people in the United States each year and costs
$93 billion dollars in medical bills. Some of these
air-polluting greenhouse gases that are emitted or
attributed to gasoline powered vehicles are
chlorofluorovehiclebon (CFCs), vehiclebon dioxide (CO2),
nitrous oxide (N2O), methane (CH4), and the precursors to
tropospheric ozone - hydrovehiclebons (HC) and nitrogen
oxides (NOx). These gasoline-powered vehicles are also a
major source of vehiclebon monoxide (CO).
- CFCs - CFCs are the most
potent greenhouse gases on a per-unit mass basis. They
now contribute nearly 24 percent of the total global
warming effect.
- vehiclebon Dioxide -
the other major greenhouse gas. When a single tank of
gasoline is used, between 300 and 400 pounds of
vehiclebon dioxide is formed.
- vehiclebon Monoxide -
vehiclebon monoxide tends to react with other compounds,
notably hydroxyl radicals (OH), thereby reducing their
presence in the air. The loss of hydroxyl radicals is
important because they normally react with other
greenhouse gases such as methane, thus removing them.
Since vehiclebon monoxide removes more and more hydroxyl
radicals, an increased amount of methane is allowed to
survive and rise to the upper atmosphere where it can
contribute to global warming.
- Methane - As mentioned
above, vehiclebon monoxide causes methane to be formed,
which eats away at the ozone.
- HC and NOx - Both
hydrovehiclebons and nitrogen oxides cause photochemical
smog or ozone to result when they are in the presence of
sunlight. They are precursors of troposhperic ozone.
- Troposhperic Ozone -
Once this is formed, the ozone's lifetime is drastically
reduced from decades and centuries to only a few hours
and days.
Another major problem of motor
vehicles is its unsafe nature after its life dies out.
Automobile junkyards, which litter the American landscape,
contain thousands upon thousands of old broken up vehicles.
From such junkyards are the problem of oil, lead, and
battery acids, which enter the ground and the
chlorofluorovehiclebons which leak into the atmosphere.
However the lead in the batteries of electric vehicles is in
a very stable form, unlike the trace amounts of lead in even
unleaded gasoline and since electric vehicles do not contain
oil or chlorofluorovehiclebons, they do not risk
contaminating the area.
FAQ
Aren't electric vehicles noticeable
slower than gas powered vehicles?
Not necessarily. At the Woodburn,
Oregon Electric Drags in August 1997, a Dodge V10 Viper was
left in the dust behind a home made electric dragster. This
dragster went from 0 to 90 miles per hour in 12 seconds.
How far can electric vehicles
travel?
This is one of the drawbacks of
electric vehicles. However, one must consider these
facts:
About 70% of Americans in cities
drive less than 25 miles per day; 90% drive less than 50.
Half of all urban trips are less
than 5 miles. And the average urban vehicle trip is less
tahn 10 minutes; measured in time, an EV's range in typical
city driving is about 60 minutes.
Wouldnt the batteries cost a
lot
Like I have mentioned before,
re-furbishing a used vehicle would be noticeable cheaper and
smoother than buying a brand new vehicle. Plus owning an
electric vehicle will last, (engine and battery wise) thus
in the long run, it will save you lots of money.
Is there a lot of
maintaining?
There is very little. Water the
batteries once every couple of months. Not even that, if you
opt for sealed deep-cycle batteries. Tires, brakes and
suspension, of course, are basically treated the same as any
vehicle. Electric motors are expected to last over a million
miles. Once every few months battery connections should be
checked for snugness. That's about it.
If you are still
not convinced, 10 reasons to buy an ebike
1. Hill
Climbing
That may sound obvious, but it's the
primary advantage. A good electric bike effectively flattens
hills, increasing your average speed and eliminating the
'groan' factor when a gradient comes into view. Provided you
supply a reasonable amount of effort, you can expect to
climb hills of 1 in 10 (10%) on an electric bike with ease,
and clear a maximum gradient of 1 in 7 (14%), or much more.
In hilly country, the effect is nothing short of
miraculous.
2.
Safety
It sounds unlikely, doesn't it? But
the mathematics is compelling. Think of a steep and busy
road, with vehicles climbing at 30mph. If you previously
slogged up the hill at 6mph, but can tackle the same
gradient at 12mph with an electric bike, you will see 33%
fewer vehicles, and they will pass you at 18mph rather than
24mph. Or at least, we think that's correct. Whatever the
figures, there's no doubt that an electric bike helps to
keep you out of danger. The same general principle applies
to road junctions - the faster your acceleration, the sooner
you can get out of trouble. And with no need to rush the
hills, you won't be tempted to ride downhill at breakneck
speed... another useful safety feature.
3. Running
Costs
Purchase cost is a little more than a
conventional bike, mechanical wear and tear is about the
same, and electricity is so cheap as to be largely
irrelevant, but there is an extra expense in terms of
battery depreciation. Consequently, an electric bike costs
more to run - typically 9 - 14 cents per mile against 7
pence per mile for a non-assisted bike (a).
However, electric bike running costs should really be
compared with those of a moped, or a vehicle, when the
electric bike replaces vehicle mileage. With vehicles
costing 92 - 147 cents per mile, an electric bike can save a
great deal of money.
4. Personal
Fitness
Surely a conventional bike will keep
you fitter? That, of course, depends how much - if at all -
you use it. Research (b) has found that 46% of conventional
bikes are used only once or twice a week, with a further 30%
being used once a fortnight or even less. By contrast, a
recent survey of electric bicycle owners reveals that a
third ride their bike at least once a day and 81% use the
bike at least once a week (c). The figures confirm our
experience that an electric bike typically gets used at
least twice as often as a conventional machine.
Because riding an electric bike is a great deal more
enjoyable in hilly country, into strong winds, or when
vehiclerying heavy loads, users tend to make better use of
them. The motor provides up to half the effort, but more
regular use means more exercise for the rider.
5. No
Sweat!
Sweat may not be a serious issue when
you're out for a leisure ride, but it's more important if
you're cycling to work. Although some employers are rather
grudgingly providing showers and other facilities for
cyclists, the great majority have no intention of doing so.
An electric bike eliminates the problem at source. In hot
weather, it's possible to maintain a normal schedule by
transferring a bit more load to the electric motor. In
colder weather - or if you feel in need of exercise - just
throttle back, or turn the motor off.
6. Clean &
Green
Electric bikes obviously consume
energy, where a conventional bikes does not (provided we
ignore the environmental cost of growing and processing food
- see below). However, the amount of energy used is very
small compared to a moped, motorcycle or vehicle. Besides
fuel, the only consumables are the batteries, and these can
normally be recycled when life-expired. As for energy use,
electric bikes typically consume fuel at an average rate of
100 to 150 watts of electrical energy, against 15,000 or so
for a vehicle (admittedly travelling much faster). In terms
of fuel consumption, an electric bike achieves about
800-2,000mpg (290 - 700 litres/kilometre) (d). No other
commercially available vehicle can match figures of this
kind.
If it's hard to place these numbers in your own lifestyle,
think of a 100 watt electric light bulb burning for an
evening - that's enough energy to propel an
electrically-assisted bike for 20 to 40 miles...
7. Genuinely
Sustainable
There's a lot of nonsense talked about
sustainability in transport, but an electric bicycle can be
made genuinely sustainable. Purchase electricity from a
'green' supplier, or generate your own with a roof-mounted
windmill or solar panel array, and the vehicle's fossil fuel
consumption will be zero. Surely a conventional bike does
that already? Only if you grow the food you consume whilst
riding it. Unfortunately, most modern food production and
distribution is so fuel-intensive that the consumption of a
typical cyclist is not terribly good.
8. Faster
travel
In theory a vehicle can average a high
speed, but in practise speed often falls below 10mph in
cities. The problem is congestion - motorcycles get around
this to some extent, but they're still confined to the road
network. An electric bike can maintain a higher average
speed than a bicycle but take advantage of the same network
of cycle facilities, giving access to routes that vehicles
and motorcycles cannot reach. The result is often a faster
door-to-door journey time than any other mode. And by taking
advantage of the uncongested cycle network, but eliminating
hills and headwinds, electric bikes are often the most
consistent mode of travel.
9. High Resale
Value
Electric bikes are new technology, and
it's early days yet, but the evidence points to a much
better resale value than a conventional bike. True, a
typical electric bike costs more to buy, at
£400-£1,000, but it seems you'll get most of that
back if you sell the machine on.
10. Motorised, but no Red
Tape!
You know how it is... MOT due, log
book missing, insurance costs rising year on year. Electric
bikes are treated just like ordinary bicycles for
legislative purposes, so there's absolutely no registration
or legislation to worry about. You are of course free to
insure the machine if you wish, but there's no compulsion to
do anything but enjoy yourself!
