A company has rolled out the first ever light-weight moto-bike where riders can choose between electric or pedal power - that is capable of nearly 40mph. Riders will be able to adjust the settings for any environment such as the countryside or city, choosing how much throttle they use at any time. Dubbed the 'moto-bike', the Bultaco Brinco comes with a removable, portable battery, aluminium frame, disc brakes, 24-inch wheels and three shock absorbers. Despite being able to travel at nearly 40mph, the whole bike, which Bultaco claim is half motorcycle and half bicycle, weighs just 39kg.
