It has been on sale in Europe for a year, but pesky federal laws that poorly define the line between bike and motorcycle made it too fast to sell in the State. Specialized Turbo, an electric-assisted bike can cruise at speeds of up to 28 mph. The 250 W rear hub motor is powerful enough to get guy up to 8 MPH over the legal limit here in America. The frame has integrated LED head and tail lights, regenerative breaking and the 342 Wh battery can be juiced in just two hours from an outlet.

One word – amazing! Alfa Romeo GTA 4C Concept was presented in Geneva Motor Show 2011. Despite of expectations is not an open roadster, but a baby version of the beautiful and sinfully expensive 8C Competizione. Carbon fiber and aluminum construction helps keep the weight down to below 850 kilograms (1873 lbs). The 1750cc, direct-injection turbo four from the Giulietta QV mounted amidship drives over 200 horsepower via Alfa’s TCT dual-clutch transmission to the rear wheels. So, we have a car with an extremely high fun factor. Alfa 4C could lead the company’s long-awaited return to the North American market.
