cyclist hits the road with the Thrustpac â€“ a petrol-driven propeller which enables bicycle users to hit speeds of up to 130kph (80mph). The device is controlled by a special glove which allows the rider to accelerate or slow down simply by flexing their index finger. Inventor Don Burgess said it can do 240km (150 miles) to the gallon, making it one of the most-fuel efficient modes of transport. Except, you know, actually cycling. 'This is a totally unique concept in the transportation world today,' said Burgess. 'The freedom from high fuel prices, the absolute fun of the wind in your hair while being pushed along effortlessly is amazing. Saving the environment has never been so much fun.' What could possibly go wrong? From here. Bicycles are small. Light. Cheap to run. Not many reasons left to own a scooter!
