The Protanium electric motor turns the Pino into an electric bicycle-built-for-two and adds even more tandem enjoyment to the tour. The powerful 250-watt hub motor provides serenity for comfort-oriented bikers. And athletic duos will appreciate the extra riding dynamics provided by the additional thrust at the starting line: When the handlebar switch is in the ON position, the motor pushes along as soon as the pedals are put in motion – either gently or full-power, depending on the setting, and is practically silent. When the pedals are not in motion, the motor is in stand-by. At 22 km/h (16 mph) the motor automatically slows. Owing to this feature, the power pack does not require a driver’s license or registration. The strong 9Ah battery rests on the luggage rack and can be easily detached and reattached. The motorized tandem has an additional weight of approx. 7 kg (15 lbs), which translates into 3.5 kg (7.5 lbs) per person. And the battery charging is just as speedy: The lithium-ion powerhouse can be fully charged and ready for the next tour in a mere 41⁄2 hours.
