6 Volt or 12 Volt

Hi can someone please explain to me the difference in performance et cetera between A Dax 70 6 volts and a 12 Volt. I thought the six Volt bikes were the early ones and the 12 V ones the latter ones but I have seen a 1990 ST 70 6 volts. Is one better than the other and if so how please. Thanks

1990 should be a 12v bike. Personally, my 1989 12v bike is a much better bike to ride with an upgraded engine .The front forks and seat are much better but they are not worth what the early bikes make. I brought what I could afford and love it. It's a keeper

It's been advertised as a 1990'6 Volt model. Its a European model. Could it really be 6 Volt ?
