Only a prototype for now
The official number for fuel economy is 2.5 Liters per 100 km (111 mpg) gasoline equivalent, and a range of 150 km (90 miles). I *have* seen better, and to be honest those compressed gas cylinders probably don't help. A lightweight plastic fuel tank containing ethanol, gasoline or diesel fuel would probably shave off another few hundred pounds of dead weight and increase fuel economy & range. Overall a very promising design, and definitely not ugly.
