Electric scooters: Love or hate them? Here's what you need to know
Scooters used to be toys only for children. Their motorized descendants, however, are
now popular among adults.
Last year, Americans took 38.5 million trips on shared scooters in more than 100
cities, according to the National Association of City Transportation Officials (NACTO), a
nonprofit organization. Those trips accounted for almost half of the 84 million trips –
more than doubled from 2017 – taken on “shared micro-mobility” options that also
include station-based bikes and dockless bikes.
As people look for ways to get around congested cities faster, scooters have gained
in popularity. But their emergence has drawn criticism that the vehicles are risky both
for riders and pedestrians.
Some cities, such as Chicago, launched pilot programs for sharing scooters in June,
eyeing the potential to ease congestion and pollution brought by cars. Portland, Oregon,
launched a 120-day pilot program last year and a one-year program this year that started
in April. New York State passed a bill in June to legalize the vehicle, though renting
them is prohibited in Manhattan – you have to own one to ride it.
But some cities said no, or at least not now. Last month, Chattanooga, Tennessee,
issued a six-month ban of the conveyance. San Francisco and Beverly Hills once took
similar approaches. Nashville's mayor called for a ban on the vehicle following the
city's first scooter-related death, but the Metro Council rejected the plan - the
legislative institute decided to reduce scooter fleets instead.
City officials and residents have conflicting attitudes toward
electric scooter. And in many
places, its regulation still falls into gray areas.
Why people love electric scooters
You can easily ride a scooter, with a top speed of 15 to 30 mph, to the nearest
subway stop a mile away or other destinations 5 miles out, and travel faster than cars
during rush hour. Unlike bikes, they can keep you from getting sweaty before you arrive
at work or to meet friends. Many people rode scooters in childhood, which makes them
familiar and appealing for commuters.
After scooter startup Bird deployed its first fleet in September 2017, bike-sharing
companies Spin (acquired by Ford last November) and Lime, and ride-hailing giant Lyft and
Uber dipped their toes into the scooter market by launching their own fleets last year.
Other key players include Skip and Scoot, which was acquired by Bird in June.
The scooter startups have raised more than $1.5 billion in funding and the global
market is expected to reach about $40 billion to $50 billion by 2025, according to Boston
Consulting Group.
Scooter hazards: safety and parking
City officials opposing scooters cited safety as their major concern and worry they
would block sidewalks if they were parked inappropriately, impeding pedestrians and
people with disabilities.
After electric scooters were introduced, several hospitals at various locations saw
spikes in scooter-related injuries at their emergency rooms. Since the fall of 2017, at
least eight scooter riders have died and 1,500 have been injured, according to Consumer
Reports. Emily Hartridge, a TV host and YouTube star, died after her electric scooter
crashed with a truck in London. Last week, a person in Atlanta died in a crash with an
oil truck while riding a scooter.
Boosted, a startup founded in 2012 that debuted with its flagship electric
skateboards, is a newcomer to the market. The company touts its
latest product Boosted Rev, which started shipping
last month, has “vehicle-grade durability.”
Its E-
scooter electric scooter has a top speed of 24 mph, can go up to 22 miles on a
single charge and has three brakes, including an electronic one, according to the
company. It costs $1,599, compared with Segway and Xiaomi’s scooters that range from
$400 to $800.
“We've adopted a lot of the fire safety and impact and durability standards from
the automotive industry for electric cars and adopted them to the standards we've
built,” said Boosted’s CEO Jeff Russakow, who compared the company’s approach in
electric scooters to Tesla's.
Own or share? What's next?
Experts said it is still too early to say whether sharing or owning will prevail.
"When you see that kind of adoption, it's quite attractive to find other
forms of business models in order to capture some sort of share," said Zarif. He
estimates that within next year, companies will come up with new forms of micro-mobility
vehicles other than electric scooters to offer commuters more choices.
Fang said there might be markets for both buying and sharing. But to accommodate the
electric scooter
ATV and other micro-mobility options, cities need better infrastructure, he said,
such as enough bike lanes, which are ideal for scooter riders who might feel unsafe
riding with cars that go 25 to 40 miles per hour on main roads but would endanger
pedestrians on sidewalks.
Cities are adapting fast though, Zarif argued. “It's getting there. I mean,
think of it as when the first car got in the road over a hundred years ago,” he said. “
The roads weren't built for the cars, but eventually they started building the right
infrastructure."
Is riding an electric bike good exercise, or just convenient transportation?
It can, if you ride right, according to a pragmatic new study comparing the
physiological effects of e-bikes and standard road bicycles during a simulated commute.
The study, which involved riders new to e-cycling, found that most could complete their
commutes faster and with less effort on electric bicycle than standard bicycles, while elevating their breathing
and heart rates enough to get a meaningful workout.
But the benefits varied and depended, to some extent, on how people’s bikes were
adjusted and how they adjusted to the bikes. The findings have particular relevance at
the moment, as pandemic restrictions loosen and offices reopen, and many of us consider
options other than packed trains to move ourselves from our homes to elsewhere.
Few people bike to work. Asked why, many tell researchers that bike commuting
requires too much time, perspiration and accident risk. Simultaneously, though, people
report a growing interest in improving their health and reducing their ecological impact
by driving less.
In theory, both these hopes and concerns could be met or minimised with e-bikes. An
alluring technological compromise between a standard, self-powered bicycle and a scooter,
e-bikes look almost like regular bikes but are fitted with battery-powered electric
motors that assist pedalling, slightly juicing each stroke.
Tailwind
With most e-bikes, this assistance is small, similar to riding with a placid
tailwind, and ceases once you reach a maximum speed of about 30km/h or stop pedalling.
The motor will not turn the pedals for you.
Essentially, e-bikes are designed to make riding less taxing, which means commuters
should arrive at their destinations more swiftly and with less sweat. They can also
provide a psychological boost, helping riders feel capable of tackling hills they might
otherwise avoid. But whether they also complete a workout while e-riding has been less
clear.
UK-based White Motorcycle Concepts has revealed the WMC250EV — a new, all-
electric motorbike that aims to
claim an EV land speed record by hitting 250 MPH with ease.
Its creator, Robert White, thinks it’ll hit 250 MPH because of some very clever
aerodynamic attributes, namely the huge gaping hole that falls right in the center of the
bike. Looking like an air tunnel, the “V-Air” duct encourages air to be pushed through
the gap rather than around the bike like conventional motors. This design reduces drag by
up to 70 percent which, again, makes the bike incredibly slippery so that it can pierce
through the air at speed.
Power comes from a unique electric layout and supply, which sees the battery pack sit
at the underbelly of the bike for a better center of gravity and good weight
distribution. “D-Drive” powers the front wheels using two 20kWh batteries, while
regenerative braking has also been incorporated to preserve wasted power from braking and
using it to recharge the batteries.
As for the rear wheel, it’s powered by two 30kWh batteries, which means in total the
bike has 100kWh of power — or around 134 BHP if we convert that to normal figures.
Weighing just 300kg thanks to a host of lightweight components and carbon fiber elements
being used for the bike and its motor, the WMC250EV now aims to take on the British and
world electric land speed records — and win them.
