The idea of an electric-assist bicycle has been around for some time, with Aprilia’s Enjoy the first really convincing argument that the genre had a future – now there’s another variation on the electric pedal-assist theme, but the ErockIT is much more a motorcycle than a bike. The whole thing weighs just 110 kilograms and with over 45lb/ft of torque and 13bhp, it can top 50mph(80Km/h)
“The driver’s pedaling motions charge the batteries and control the motor, which multiplies the rider’s effort by a factor of 50. The faster you pedal, the faster the 12 horsepower electric motor rotates. The high torque of the electric motor enables spectacular acceleration.”
