KTM 450 EXC

The Specs

Price: $9198
Engine/trans: 449-cc liquid-cooled single/6M
Horsepower: 43
Weight: 251 pounds
Suspension travel, F/R: 11.8/13.2 inches Seat height: 38.8 inches
0–60 mph: 5.19 seconds
1/4-mile: 13.84 seconds @ 92.94 mph
60–0 braking: 150.59 feet
Fuel economy: 45.41 mpg

The Good

• The motor is incredibly responsive and emits an authoritative, barky exhaust note. We admire the attention to detail with common fastener sizes for quick maintenance and disassembly. The KTM can supply as much performance as the rider can handle, which can be incredibly entertaining. With street tires, it would be even quicker.

The Not-So-Good

• It feels happiest in max attack mode, when you’re hard on the gas and pounding bumps. When cruising, the long travel suspension is surprisingly harsh, and the narrow, hard seat is not suitable for extended rides. The knobby tires make for a tiny contact patch—road traction is limited.

The Bottom Line

• Brash and intimidating for novices, but has a potential unmatched in this group.

Best Suited For

• Expert or advanced intermediate riders looking to grow into the sport.

Yamaha XT250

The Specs

Price: $4690
Engine/trans: 249-cc air-cooled single/5M
Horsepower: 16
Weight: 271 pounds
Suspension travel, F/R: 8.9/7.1 inches Seat height: 33.0 inches
0–60 mph: 9.82 seconds
1/4-mile: 17.20 seconds @ 70.63 mph
60–0 braking: 143.80 feet
Fuel economy: 52.77 mpg

The Good

• The Yamaha was the least expensive bike here, but it certainly didn’t feel cheap. While it has just two more horsepower than the Honda, our test team noticed the XT250 felt much stronger. “The Yamaha is small but gutsy,” Hyneman says. The XT250 proved to be a great rock crawler, and with almost no learning curve and near 53-mpg fuel efficiency, it’s probably a great commuter too.

The Not-So-Good

• The distance from the seat to the foot pegs is 19.5 inches, the shortest here. So if you are 6 feet tall, this makes for a cramped cockpit. The rear suspension seemed too soft for heavier adults. Like the Honda, fast and rough off-road riding overwhelm the suspension’s damping ability, and the motor doesn’t have enough power to keep pace with the bigger bikes on the highway.

The Bottom Line

• A near twin to the Honda but in a more powerful, more intermediate-level package. For an extra $1400, Yamaha offers the WR250R with a lot more giddyup—a better choice for hardcore dirt riders.

Best Suited For

• Beginner to intermediate.

Kawasaki KLX250S

The Specs

Price: $4999
Engine/trans: 249-cc liquid-cooled single/6M
Horsepower: 20
Weight: 278 pounds
Suspension travel, F/R: 10.0/9.1 inches Seat height: 35.0 inches
0–60 mph: 8.60 seconds
1/4-mile: 16.64 seconds @ 73.54 mph
60–0 braking: 127.61 feet
Fuel economy: 49.27 mpg

The Good

• An excellent compromise between easy-to-ride play bike and full-fledged racer. Suspension is set at a comfortable height, but still has plenty of travel to absorb large hits. It feels light and flickable—great on twisty roads. Clutch and brake effort are wonderfully smooth. Unlike most of the bikes here, the KLX comes with a tachometer. Amazingly, the Kawasaki costs the same as the beginner bikes here.

The Not-So-Good

• The high-revving engine has to be wound hard to gain sufficient thrust. While the liquid-cooled engine clearly provides more poke than the other 250s, it also has more stuff—radiators, water pumps—that could fail.

The Bottom Line

• The KLX is docile enough for a newbie, but provides a wide-enough performance envelope to keep an advanced rider entertained.

Best Suited For

• Beginner to expert.

Honda CRF230L

The Specs

Price: $4999
Engine/trans: 223-cc air-cooled single/6M
Horsepower: 14
Weight: 267 pounds
Suspension travel, F/R: 9.0/6.3 inches Seat height: 31.9 inches
0–60 mph: 10.81 seconds
1/4-mile: 17.64 seconds @ 68.66 mph
60–0 braking: 130.68 feet
Fuel economy: 54.16 mpg

The Good

• The controls all have a light, progressive feel that makes operation effortless. The wide, soft seat is a comfortable perch. The smaller dimensions give inexperienced riders confidence. And when it comes to reliability, the Honda is probably bulletproof.

The Not-So-Good

• The engine could use at least another 5 hp, and our inner gearhead wants more exhaust growl. With tires biased for on-road performance and short suspension travel, the CRF isn’t a hardcore off-roader.

The Bottom Line

• It’s easy to ride, forgiving—and fun. But it was the 54 mpg and the under $5000 price that really made us smile.

Best Suited For

• Beginner to intermediate, and anyone who values a low seat height.

Suzuki DR-400S

The Specs

Price: $6099
Engine/trans: 398-cc liquid-cooled single/5M
Horsepower: 35
Weight: 317 pounds
Suspension travel, F/R: 11.3/11.6 inches Seat height: 36.8 inches
0–60 mph: 5.9 seconds
1/4-mile: 14.72 seconds @ 83.72 mph
60–0 braking: 133.95 feet
Fuel economy: 46.68 mpg

The Good

• It has nearly all the punch of the high-powered KTM, so it can keep up with highway traffic. The power allows you to effortlessly work the rear end in the dirt. But it’s as docile as the smaller bikes. The DR-Z400S was the only bike here with vibration-damping rubber foot-peg inserts.

The suspension’s initial compliance did a solid job smoothing out the bumps. And this bike has been around for a while, so there’s tremendous aftermarket support.

The Not-So-Good

• It’s the heaviest bike here, and the high center of gravity combines with the tall seat to create a struggle for shorter riders. For serious off-road duty, it needs more aggressive tires. Some noticed a sharp, uncomfortable edge in the seat foam.

The Bottom Line

• A terrific all-around motorcycle that can be modified to suit almost any rider taller than about five-foot eight.

Best Suited For

• Beginner to expert.

Aptera Electric Car Stops Traffic (Literally) on First Drive in NYC: Gallery

An article from Popular Mechanics. What a cool vehicle. I don't mind having
one - if the price is right.
----------------------------

NEW YORK - You don't see this many cameraphones pulled out in this town
short of a Britney Spears sighting. We sure as heck haven't seen as many
wide-eyed onlookers for a car here before. "Does it fly?" asked one of the
dozens of New Yorkers crammed outside the Hearst Tower as the Aptera Typ-1e
electric vehicle pulled up to accept its Breakthrough Award.

No, the Aptera doesn't fly, but it can hit 120 miles per gallon right now,
and it's headed for production this fall. We already took the first Aptera
test drive last December, so we let our Jalopnik buddy Ray Wert sit shotgun
for a trip around the block as the aerodynamically awesome car, on its first
trip to the East Coast, made its way around the corner to tonight's
Breakthrough Conference and Awards Presentation, where other winners in
alternative energy-as well as space, appropriate technology and much
more-are already wowing the crowds. Even legendary astronaut and PM
editorial advisory board member Buzz Aldrin walked away impressed. See his
and the Big Apple's reaction with the gallery at left, and stay tuned for
much more live coverage right here.

2008 Zero X Electric Motorcycle Test Drive

An article from Popular Mechanics.
--------------------------------------------------

Hot, Clean Fun in the Summertime With 40-Mile Range (and 60 on the Way!)

LOS ANGELES - We're chatting with Neal Saiki, inventor and founder of Zero
Motorcycles, as we ride his new Zero X dirt bike down the beachside bike
path here. Halfway to Santa Monica, two things occur to us: We've never
interviewed anyone while riding a motorcycle (yes, it's that quiet), and,
um, we're probably breaking the law. This electric motorcycle is smaller
than a conventional 250 cc dirt bike, but it's most certainly not a bicycle.
And we're on a bike path-oops.

Seconds later, officer Blake Budai of the Los Angeles Pacific Patrol
Division wheels his Toyota Tacoma police truck off the paved parking lot and
onto the beach to chase us down-double oops.

Fortunately for us, this is one cool officer. And like just about everyone
we meet while riding the Zero X, he's impressed. Budai not only lets us off
easy (thank you, sir!)-he takes a ride himself, grabs Saiki's business card
and asks about potential patrol units. The remainder of our test ride goes
down in a very large-but very legal-parking lot ... where we answered quite
a few more questions from locals. The Zero X, after all, creates a buzz
wherever it goes. -Ben Stewart

The Specs
At 140 pounds, the American-made, $7450 Zero X weighs in about 100 pounds
lighter than a typical 250 cc dirt bike. The weight savings come from the
green wheelie machine's diminutive size and 6061-T6 aluminum frame, which
tips the scales at a feathery 18 pounds.

Between those rails sits the easily removable, 40-pound, lithium-manganese
spinal battery pack. "That's our secret sauce," Zero's Saiki says of the
power source, which he says can recharge in 2 hours for 2 hours of driving
or a 40-mile range, depending on conditions. The unit is fully recyclable
and can be swapped for another one in a mere 30 seconds. The 58-volt, 2.2
kwh pack is a proprietary design with 168 cylindrical cells, each with its
own heat sync for cooling. The pack itself costs around $3000 and is built
to last about six years, or 600 full-depth charging cycles.

The battery supplies power to a 17,400 watt, 23-hp electric motor, which is
actually very similar to the units in many neighborhood electric vehicles
(NEVs) like the GEM. The motor spins a fine-pitch, lightweight chain hooked
to a big, 72-tooth sprocket at the rear wheel. The larger the sprocket, the
quicker the acceleration-but more on that later. Speaking of wheels, the
rims have a special 20-in. hollow design to save weight, wrapped with
75/90-20 tires. Size-wise, the wheel and tire combination is essentially
halfway between a mountain bike and a motocross bike. And Saiki says just
about any bicycle shop can service the wheels, tires and brakes.

The Ride
The Zero X is so small and light that it feels more like a big, electric
mountain bike than anything-quite the easy ride. The key, tethered to your
wrist as a kill switch in case your butt leaves the seat pad, clicks forward
one notch, and you're ready to ride. Saiki says it's easy to over-goose the
throttle thanks to the instant torque of the electric motor, so he suggests
we flick the "0 to 30 mph" switch and the "easy" power delivery selector. We
listen.

The bike pulls away smoothly in those modes and accelerates briskly. Its
lightweight and adjustable suspension, with a generous 8-in. front and 9-in.
rear travel, makes you feel invincible. We yearn for a dirt motocross track
instead of this oceanfront pavement.

Then we stop and switch to "0 to 60 mph" mode and flick the other lever to
"Sport." Twist that right grip, and the Zero X will pull the tire a few
inches off the ground as it accelerates-even with your weight pitched
slightly forward. Saiki says it can hit 30 mph in just two seconds, and
cautions that "the battery dumps a lot of amps-really quick." Indeed. It
pulls serious wheelies-if that's what you dig. Hold the grip pinned, and the
bike starts some serious speeds. It's a blast.

But the speed of the Zero X may not be as important to some as its silence.
We can imagine a casual trail ride on a pair of these bikes where both
riders can not only hear the sounds of the wilderness around them, but also
carry on a conversation as they ride. Try that on a two-stroke.

So how do you get one? The Zero is in production now-ready to be shipped
exclusively from Zero's Web site, delivered to your door in three crates
(wheels, battery and frame components) or fully assembled on a pallet.

The Bottom Line
On our half-hour ride, we didn't get a chance to sample the dirt prowess of
the Zero X. Nor did we get a chance to measure the miles covered on a full
charge. But if the claims are true-and we have no reason to doubt them-bikes
like the Zero could be the future of off-road riding.

It might be the future of on-road riding, too. Zero gave us an exclusive
first look at their new 2009 street-legal Supermoto bike. The Supermoto will
have a larger 3 kwh battery for a range of 60 miles and a top speed of 65
mph. Zero is also planning a commuter bike for the future. We can't wait to
try either one of those clean machines.

2009 Suzuki GSX-R1000 K9 Test Ride: 155 hp Superbike-Max Performance and Refinement

It's tempting to think that ever-increasing levels of motorcycle performance
will tend to produce greater compromises in driveability, comfort and ease
of use. But the latest crop of 1000-cc sportbikes is beginning to make that
supposition look ill-founded. And that's certainly true when it comes to the
2009 Suzuki GSX-R1000 K9. This Suzuki somehow combines mind-boggling
performance, slick ergonomics and, yes, even refinement. Let's take a ride.

The Specs
The big Gixxer is all-new for the first time in 10 years. So there's a fully
revised 999-cc inline four-cylinder that has been shortened by almost 2.5
inches as a result of stacked transmission shafts in a new two-piece
crankcase casting. The countershaft is now almost directly above the
driveshaft.

A so-called crankshaft-end lubrication system has been adopted, and the
compression ratio has been increased from 12.5 to 12.8:1. The bore-to-stroke
relationship is now even more oversquare, and the entire valvetrain has been
redesigned, with larger titanium valves throughout to allow race teams more
leeway when prepping for competition.

Clutch operation is accomplished by a mechanical cable system, again
requested by racing teams, and both oil and coolant radiators are new
race-derived shapes. To comply with the latest, more stringent noise
regulations, the K9 GSX-R1000 wears dual titanium tailpipes (400 grams
lighter than 2008's pipes) behind an underbelly catalyst chamber. The
chassis is new from the ground up, and the wheelbase is a half-inch shorter
despite a swing arm that is now 1.3 inches longer.

The rear suspension benefits from a new shock linkage, while at the front
Suzuki has employed Showa's big-piston-fork concept, which improves control,
reduces dive, and provides better front-end feel for the rider. Both ends
feature full adjustment, with rebound plus high- and low-speed damping
settings. An electronically controlled steering damper is fitted as
standard.

Weight has been pared off every part one can imagine, including the brake
calipers, which are now monoblock units grasping 12.2-inch rotors that float
on lightweight alloy pins. Yes, the wheels are lighter too, and the overall
reduction in mass, according to Suzuki chief engineer Hiroshi Iio, is 11
pounds.

As in 2008 models, Suzuki employs three selectable engine-power-delivery
maps, but has moved the selector switch to the left-hand switch module. As
before, the "A" setting provides full power (and is the default position on
start up), with the "B" position providing softer acceleration up to 50
percent throttle openings, and the "C" position dialing down the power
throughout the operating range.

The Ride
Even for one with experience aboard literbikes, the Suzuki's mind-numbing
thrust comes as a fresh reminder that 155-horsepower at the rear wheel on a
machine that weighs in at 470 pounds is not to be trifled with. In normal
riding conditions, the GSX-R needs no more than 5000 or 6000 rpm to have the
traffic drop away in the mirrors like coins down a well.

It takes real resolve to hold full throttle as the revs climb toward the
13,500-rpm redline and the engine-speed indicator LEDs wink on sequentially
to suggest an upshift. The ferocity of this bike's acceleration when the
tach is reading in five digits beggars the imagination. Few people can
really review the experience because one's mind is just so acutely focused
on staying on the bike, holding it on course, and looking ahead down the
narrowing tunnel of an overloaded visual-processing faculty. Yes, it's
insanely quick.

The irony here is that the new GSX-R1000 is a real pussycat to ride around
town. Throttle calibrations are spot on, and the clutch takeup is smooth and
predictable. There's enough power low down the rev range to easily toddle
around the suburbs. And while the shifter on our bike was a bit notchy and
switchlike in its operation, no doubt more miles of break-in would tame its
behavior to a civilized extent.

Even the riding position is comfy when compared to some of the sportbikes,
with a relatively relaxed "ergonomic triangle" (the relationship between
feet, seat and hands), and adjustable foot pegs for a little extra
fine-tuning. Wind protection is good, and the seat is wide, well padded, and
at an angle that helps spread the contact patch.

But beyond its creature comforts, the new K9's most charming attribute is
its handling. The bike responds to the bars and subtle weight shifts with
quick and easy movements. There's nothing lost between input and response,
but the machine is in no way twitchy or nervous. Indeed, the entire chassis
displays superior damping in every plane, quickly encouraging its rider to
start exploiting its huge potential.

This bike runs up the mountain at a rate that taxes the old noggin's clock
speed, but without getting near the limits of grip or ground clearance. In a
sense, it's too good for the road. Like all modern ultra-high-performance
vehicles, you have to go so fast to make it work hard that you can get well
out of your comfort zone and into legal difficulties before the machine
breaks a sweat.

That's only a downside if you are (a) sensible, and (b) mortal. And that
probably explains Suzuki's drive-mode selector (S-DMS), which allows riders
to effectively detune the bike. We have our own DMS at the right wrist. The
throttle, as they say, goes both ways. Besides, once you've pushed the
button at your left thumb to bring up the S-DMS menu, it is prone to
accidental mode shifts as you move your hand around. Better to leave it in
the default startup mode, where brief nudges are not enough to change
settings.

Hard-core bikers will ditch the dual titanium pipes for something louder,
but we liked the combination of muted exhaust growl (overlaid with a
decidedly resonant induction snarl) and the smooth operation of the
counterbalanced inline Four engine.

Along with the firm ride comes a beautifully damped suspension, with the
power you get a smooth and flexible engine, and with the rest of the
controls there's a distinct sense of quality accompanying the action.

Most of the population may look at a GSX-R1000 and see an outlaw or a
hooligan, but under the track-refugee styling lives a very well-mannered
giant. Of course, you'd need professional racing experience to fully tap
this bike's potential. But remember, it won't bite you unless it's provoked.

The Bottom Line
At $12,899, you can own a vehicle that has performance something akin to a
road-going F1 car: Zero to 60 mph in two-something seconds, the quarter-mile
in nine-something seconds at over 145 mph and passing performance that often
feels like an over-achievement of a simple task.

In sixth gear on the highway, a twist of the wrist pulls triple digits up
onto the speedo display quickly and with no trace of exertion. Staying under
90 mph on any freeway requires constant attention-that's how relaxed it
feels. The GSXR-1000 is an awful lot of machine for just thirteen large.

2008 Piaggio MP3 500 Test Drive: Clever Trike Delivers 60 MPG, Tons of Fun

LOS ANGELES - Don't let the silly name fool you: Piaggio's MP3 may inspire
iPod jokes, but this odd-looking three-wheeler is rapidly building a cult
following on American roads. The MP3 is essentially a scooter with two
wheels up front for more stability. We were skeptical, but the suspension
engineering really works well-and the scooter's a blast to ride.

While testing the $8899 500-cc model on the roads here, we got plenty of
head-twisting attention in trendy neighborhoods already overrun with
exotics. Difference is, we got about 60 mpg on our cruise. Not too many
exotics (okay, none) can claim that kind of fuel economy. Clad with matte
black paint, rally-style headlight shields and double-steel-tube bumpers,
the industrial-looking MP3 is bursting with cool features, like an underseat
power supply for laptop or cellphone storage. The smallish seat might be a
bit cramped for bigger riders, but that's nothing an aftermarket saddle
can't cure.

All you need for brisk acceleration is a twist of the wrist, and the MP3's
automatic continuously variable transmission takes care of the rest. And it
keeps on pulling, right up to 90 mph. The MP3 may look cumbersome to ride,
but it turns and leans surprisingly easily-up to 40 degrees thanks to the
aluminum-armed parallelogram suspension components.

An electro-hydraulic locking mechanism lets you keep your feet on the
floorboards at low speeds and helps the trike stay balanced when parked on
hills. Twin 120-mm front tires offer twice the contact patch of a
motorcycle, encouraging higher speeds and more aggressive turns than regular
scooters do. The 140-mm tire at the rear keeps you planted when the road
gets twisty. The MP3's sure-footed handling inspires surprisingly
crotch-rocketesque body leaning. It's even narrow enough to split lanes.
Two-piston floating-caliper front and rear brakes offer strong stops, but
the lack of an ABS system means the rider is responsible for keeping the
wheels from locking up. And remembering which of the two levers operates
which set of brakes is imperative during panic stops.

While the MP3 was fun to ride on urban roads, options like a TomTom
navigation system could make this frisky three-wheeler a fetching
long-distance cruiser.

My dream scooter! Pity it has not come to Malaysia yet. Due to the tax
structure, a 500 c.c. motorcycle would be too expensive.

Electric Bike Hits 75 Miles Per Charge

Power Shift: A handlebar-based controller lets you switch between three
power settings to place more emphasis on muscle or motor. Motion Measure:
The torque sensor tells the 250-watt DC motor how much power it needs to
supplement your pedaling. Dual Charge: A pair of 26-volt lithium-ion
batteries help power you up to 75 miles.

While electric bikes have been growing in popularity, they are typically
hampered by paltry ranges resulting from limited battery life. Because the
Giant Twist Freedom DX ($2000) runs on a cyborg like mix of muscle and
machine power, it can travel twice as far as most powered cycles-up to 75
miles per charge.

When you pedal, an integrated torque sensor summons the perfect amount of
power from the bike's front-hub motor to keep you at a steady pace; pedal
harder and the motor settles down, take a rest and it kicks into overdrive.
The bike comes out in May, and the manufacturer tells PM that it sees the
technology eventually taking off in developing countries, where it could act
as a low-cost option for carless commuters.

This article is very interesting. I would be tempted to buy one but the
price of USD2,000 is a bit too steep for me.

With Electric Scooter, MIT Hopes To Rev Up Practical Transport

CAMBRIDGE, Mass. - It's a humble home for what might be the future of urban
transportation. Locked in an office here at MIT's Media Lab is the latest
prototype of the RoboScooter, delivered just one month ago from Taiwan.
Outside this room, the Media Lab is almost too eccentric for words: an open
space lined with offices, teeming with art and an explosion of plant life.
It's the exact opposite of this austere little space, where the scooter's
detached seat is sitting on the floor and wires snake from the cavity where
the removable battery pack should be. The rear wheel is clamped in place,
and under the fluorescent lights, in these cramped quarters, the RoboScooter
looks like a hospital patient. Its immediate prognosis is still up in the
air, but here's the good news: Whatever it eventually looks like, and
whatever it actually does, this vehicle is going to make it.

And then, there's the inevitable bad news: The first-gen RoboScooter will
not be very robotic. The original concept developed by the Media Lab's Smart
Cities research group called for wheels that were essentially self-contained
robots, with dedicated processors that could optimize braking and
suspension. In a four-wheel configuration, these wheeled bots would also
control steering. The group's City Car design, for example, allows each
wheel to turn independently. For a scooter, computer-controlled steering
isn't necessarily more efficient than old-fashioned handlebars. But for now,
the point is moot, because the first RoboScooters to hit the streets won't
have wheels any more intelligent than a Vespa's.

But here's what makes it smarter: The RoboScooter will be entirely electric,
with at least one lithium-ion battery pack that can be swapped out for
another, fully charged one. And although the exact mechanics haven't been
finalized, the scooter will have the ability to fold into itself, with its
rear wheel sitting alongside the front one. That covers the cool stuff that
might convince you to eventually buy or rent one. But the RoboScooter's
biggest innovation-one with the real potential to change the state of urban
transportation-is on the assembly line. "A traditional internal combustion
vehicle might have 1200 to 1500 parts," says William Mitchell, director of
the Smart Cities research group and a professor of Architecture & Media Arts
and Sciences. "RoboScooter has 150."

Hybrid vehicles are even more complex, sometimes requiring upwards of 25
percent more parts than their internal combustion counterparts. "Hybrids
have a niche in the short term," Mitchell says. "But in principle, they're
going in exactly the wrong direction. They're doubling the complexity
instead of what we should be doing, which is halving it." The RoboScooter
trims parts by way of being all-electric, but also with its straightforward,
borderline minimalist design. "We are religiously pushing the proposition
that we should get rid of the sheet metal that usually encrusts a scooter,"
Mitchell says.

This dramatic reduction in parts could mean dramatically cheaper production
costs for Taiwan-based manufacturer Sanyang Motors (or SYM). It could also
have an impact on similar electric vehicle projects, like the City Car.
While that design hasn't found a partner willing to commercialize it, a
low-cost, streamlined production process could allow small firms, both in
the United States and abroad, to seriously consider getting involved. To
Mitchell, everything is riding on RoboScooter.

Today, however, no one is actually riding the scooter, and it's hard to tell
when anyone will. The prototype is a work in progress, and the researchers
at MIT still have to finalize its electric propulsion-and how to collapse
it. The final product won't be able to shape-shift Transformers-style at the
push of a button. But the driver won't be expected to wrestle it entirely on
his or her own-the scooter might have spring-loaded components, or the kind
of hydraulic system that allows car trunks to open themselves. Also in
question is how the vehicle will be charged. Developers originally
envisioned charging racks distributed throughout a city, which could double
as rental stations where users would buy a one-way trip. If SYM ever decides
to take that leap, adopting a business model that's a cross between services
like Zipcar in the U.S. and the successful Parisian bicycle rental program,
it could be the biggest endorsement yet of one-way, short-trip vehicle
rentals.

If-and let's be clear, it is a very big if-the RoboScooter takes off when
its introduced in Asia, the benefits could quickly snowball. The wheels may
not be robotic now, but the architecture is already in place for future
generations of the scooter; the wait now is for computer-controlled
components like the electric brakes currently being developed by Siemens.
And if a RoboScooter rental system turns a profit, it could not only prove
that short-trip, one-way electric vehicles are feasible, but possibly change
the current perception that EVs will only become useful when they have the
range to travel cross-country. One potential upside might be a battery lease
model for the scooter's swappable li-ion packs, reducing the cost of
ownership and solving the complicated warranty issues associated with
plug-in vehicles.

As excited as Mitchell is about the RoboScooter, he has no delusions about
where it will be successful. "Scooters are perfect for Asian, European
markets. They aren't a good model in the States. They're trendy for art
directors," he says, "but the expectation of safety is higher here." For the
United States, Mitchell has a very different vision from the near-term
impact of a City Car-like electric vehicle. It's a more ambitious,
multi-modal, one-way rental model. A user might rent a scooter or bicycle to
get to the supermarket, and then rent a car to bring his groceries back
home. Far-fetched as that scenario sounds, every one of its components is
entirely within reach, from a technological standpoint. The hard part will
be convincing companies to take the initial plunge. For its part, the Smart
Cities group expects to present what Mitchell describes as a "good, working
prototype" of RoboScooter to SYM by April 1. If all goes according to plan,
the scooter could hit the market in Asia as early as next year.

Something interesting from MIT. The scooter looks damn cool!

Electric scooter hoping to spark eco two-wheelers

This article from CNN is very exciting for me. I would like to own an electric vehicle but an electric car is too expensive. A scooter could be just nice.
-------------------------------

Lean, green electric machine: KLD are hoping to kickstart the electric scooter industry with their new engine.

(CNN) -- Much has been made of the electric car driving to the rescue of ailing automobile manufactures and saving the planet at the same time. But what if that eco-savior came on two wheels instead of four?

A high price tag, a limited range, sluggish performance and the tendency not to work when they get wet, have meant that electric scooters are a rare sight on the roads.

However, KLD Energy Technologies, an electric engine company based in Texas believes that its new electric motor can overcome all these problems and kick-start the sector. It's teaming up with Vietnamese motorbike manufacturer Sufat to produce an affordable electric-powered scooter that has a performance just as good as a normal petrol powered bike.

"We chose Vietnam [to launch the bike] because they're 22 million scooters in a country of 85 million people, that's a lot of people riding scooters in a contained area and the pollution is a concern. All governments in southeast Asia are looking for solutions [to pollution problems], but so far there hasn't been one. We believe that we've found that solution," Christian Okonsky, founder of KLD Energy Technologies told CNN.

Rather than looking at making batteries more efficient, KLD have improved the performance of the engine itself, building an engine using nano-crystalline composite materials, which the company believe makes it ten times more efficient than traditional iron core motors, and giving it an output of 2500 hertz.

Together with a computerized motor control, the KLD engine is compatible with any type of battery. Top speed of the KLD scooter is about 55 mph, which is almost double that of many electric scooters and delivers twice as much torque, accelerating from 0 to 50 mph in ten seconds. The engine also doesn't require a transmission.

Range on a full charge depends on the type of battery used although in tests KLD say that their motor system extends the distance a battery can go before a charge is required by 40 percent. If a typical battery can go, for example, 30 miles with a traditional electric motor, it is able to go 45 miles.

Cost-efficiency of components and years of technological development have created the engine KLD have the sole license to produce.

"The nano-crystalline material was developed 20 years ago, but it was incredibly expensive and people couldn't figure out how to use it in a motor. Even 10 years ago a computer to run this kind of high frequency engine would have been more like the size of a desk top computer. The magnets we use today that costs 20 cents, 10 years ago would have cost $4 to $5," said Okonsky.

Vectrix Electrics is another company that has been developing electric scooters, so far selling only in North America and Europe. While the performance of its scooters is comparable to KLD's, their models sell at a much higher price tag around $11,000. Earlier this month Vectrix reported financial difficulties and has been forced to make staff cuts.

Okonsky, however, remains positive that the KLD scooter engine will be success and there is a market for electric powered scooters. By the end of the year KLD are aiming for 2,000 scooters a month to be produced by Sufat with their electric engine. The projected retail price is around $1500, only slightly more than Sufat's existing bikes that sell in Vietnam for between $800 and $1250.

"Among two-wheelers a scooter is the best for electric drive," auto industry analyst John Wormald of Autopolis told CNN.

"A motorcycle is too performance-driven, so it's not really suitable, but a scooter would be. For many electric bikes with very limited battery capacity, the power is just an assist and the battery can be heavy which isn't a great if your cycling."

Yet the market for electric bikes -- the pedal variety with a battery pack -- has been booming, particularly in China. According to the China Bicycle Association, sales of electric bikes in China stood at 58,000 in 1998, compared with the 20 million recorded just a decade later in 2008.

However, rather replacing cars, the majority of electric bikes are affordable substitutions for bicycles, as Chinese cities continue to grow and daily commutes get longer. Their impact in reducing pollution then is open to question as car sales in the country continue to rise.

Ultimately the real eco-credentials of electric vehicles depends on how the electricity is generated, but for helping to relive vehicle exhaust-filled streets, especially in Asia's two-wheel dominated city centers, electric mopeds could go a long way.

As the idea of electric vehicles as viable substitutions for petrol-powered one becomes more widely accepted, Okonsky's bigger challenge will convincing skeptics that the old problems of electric scooters have been overcome.

"I'm always asked, 'What happens if I go through a puddle, will it still work?' The answer is yes," Okonsky said.

In fact, Okonsky says that they've tested their engine underwater and it still works -- expect a video of the trial on KLD's Web site soon.

Ducati Street Fighter and Street Fighter S

Unlike the other bikes Ducati has been making for years, this Italian motorcycle manufacturer is now producing some rides that don’t require a spine of steel and titanium wrists to enjoy. And that’s largely because most of their buyers are, yes, getting older and don’t go for hardcore street bikes like they did when they were a bit more spry. To that end, the mighty Streetfighter and Streetfighter S position the rider upright. And these bikes are feather-light at 370 or so pounds. This pair also feature “DTC”---Ducati Traction Control---the better to keep you perpendicular.

Aprilia Shiver SL 750

Think of the Aprilia Shiver as a 7/8th scale Touno—Aprilia’s original naked standard bike. It’s the perfect city bike, and if you get it with the gold-covered handlebars, trellis frame and brakes, well, you may just find your inner Elvis. The 90-degree V twin gives a generous 95 hp, and its sculpted, sporty tank, seat and tail unit emphasize its peanut-sized dimensions. The engine and frame sweetly merge with the overall design, and the under-seat exhaust system follows the bike’s aggressive lines.

Kawasaki Ninja 650 R

Okay, this bike may not grab the headlines like certain choppers at this show, but at $6800 the Ninja is inexpensive, quick, and delivers a mighty impressive 51-mpg. Versatile, powerful and striking, the 650R is well suited for slicing through city traffic, as well as hitting the back roads or a track day thanks to its phenomenal roll-on capabilities, lightweight trellis frame and responsive steering.

The Scarface Special

Every bike show has a few wacky customs, but this tricked-out 2006 Suzuki Hayabusa, owned by Steve LeBron and customized by Dennis Vasquez, is a particularly well-done tribute to Tony Manero of “Scarface.” It’s got a (fake) .32 pistol and bullets mounted under fiberglass in the gas tank. There’s a protruding arm holding a (fake) gun that shoots nitrous oxide jutting from its right front cladding. Oh and don’t forget about the machine-gun cylinder in the rear that spins when the bike’s in motion.

Star V-Max

The brand-new Star V-Max cruiser delivers a mule-kick performance from its all-new 65-degree, four-valves-per-cylinder, 1679cc V4 powerplant. The V-Max is one of the baddest bikes on the market this year. Its luminescent multi-function display is techy-cool and its combo of black and gray paint lends it a particularly angry, menacing street look.

Harley-Davidson Tri Glide Ultra

Purists say a bike with three wheels just isn’t a bike. Well even the hardcore amongst us might make an exception for the Tri Glide Ultra. Inspired by the Servi-car models built from 1932 to 1973, this 2009 model is decidedly a softer ride than its predecessor, and comes with a lot of cool retro accessories. Harley says it also gets great mileage (appx. 46 mpg), especially given its whopping 1174-pound weight.

Victory Street Vision Anniversary

The Street Vision is, plainly speaking, an enormous bike. Even the front foot rests look as though they could accommodate Shaq’s sneakers with room to spare. With its predatory triangular face, ant-segment-like gas tank and 106-cubic-inch Freedom V-twin coupled with a skinny seat, this bike announces your presence on the road like few others. They’re rare, too; Victory’s only turning out 100 of these anniversary machines.
