When one of your
car tires goes flat, there are two things you can do, you can complain and
change it or, if you don't have a spare, stand helplessly beside the road and
hope someone comes to your rescue. Now comes a third choice, called Quick wheel.
It is designed to get disabled motorists rolling again as quickly as possible.
Quick wheel is
basically a tiny emergency trailer-complete with three tough little wheels of
its own-that supports the flat tire and enables the motorist to drive to a service
station without losing much time or expending much energy. The product is made
in the Netherlands but is owned and marketed by a US company, Quick wheel Inc.
of Greenwich, Connecticut. According to the firm's president, Robert Bockweg,
the product meets each of the major worries that customers relate with flat
tires: safety, lost time and physical labor.
To use it,
motorists simply unfold the product to its fully extended position, set it in
front of the disabled tire, drive the car onto the Quick wheel's ramp(斜板) and
fix a special safety strap over the tire. The tire is then locked, or cradled,
in Quick wheel's metal frame. Its three wheels do the rest of the work.
According to Quick wheel Inc, its product can be driven "for miles"
at the speed of up to 45 miles per hour "without any noticeable change in
the vehicle's braking (车辆刹车) or
steering operation". The company also says that it can be used on just
about any type of car, jeep, mini-van or trailer (拖车).
Bockweg says that
Quickwheel will be sold first in the United States, at a price of $150. Sales
agreements now being talked over should make the product ready for use in
Japan, Canada and Western Europe in the near future. (words: 314 ; time :5ms)
