I drove so far only 700 km (400 miles) with one and so far the consumption with 2 persons is very good. About 4 l/ 100km. The minimum I have obtain was 3.52l/ 100km. good suspension. due to 21" front wheel I found that is necesary strong arms to turn left or right at low speed. the only problem I encounted was this: when I run down a hill even if my fuel tank is almost full the empty gas light goes on. first time when it hapens I went to the first gas station and have it full. 5 liters were enough to have it full. this means that with 10 liters of fuel in the tank the light went on. if you need any other details please send me an e- mail.
