Oracle of DelphiPanasonic Lithium Vivi RX-10S - the Electric Bicycle
July 7th 2008 22:45
The Panasonic Lithium Vivi RX-10S is a regenerative electric bicycle due for release in late August and works by regenerating energy dissipated from braking forces to charge a Lithium-ion secondary battery which in turn delivers a travel range of 125km - up from 90km without the regenerative braking system.
A motor is mounted on the front wheel along with a one-way clutch on the pedal shaft while other features include an auto-mode which can select the assistance force for you in four pre-determined levels - high, medium, low, and off - depending on the riding condition. The riding condition is estimated based on the value obtained by a torque sensor that measures the pedaling force accordingly.
So say if you are pedalling uphill, the auto system will switch to 'high' for maximum assisted force or turn itself off when no assistance force is required, i.e. travelling downhill.
Priced at US$1,395, Panasonic has set an annual sales target of 3,000 units. The bicycle goes on sale in Japan on August 20. [techon.nikkeibp.co.jp]
