They have a 35 km/h version of the V-mini motor (180 Watt by 2.5 kg) and a li-ion battery (36v/9Ah by 2.4 kg).
So the complete package is under 5 kg where my Dingo is 18 kg ready to go (with mud guards and all).
Should make for a very nice hybrid vehicle. Even when peddle in a very relaxed way in order to not sweat I can then still do 35 km/h over 50 km with that upgrade. This range can be much extended if I peddling harder myself.
At 0.24 per kWh recharge cost (including all costs like taxes etc); it'll come out at 0.10 per recharge or at least 0.002 Euro per km. Compare that to about 0.08 Euro per km that a European fuel efficient car gets. (a factor 40 difference)
