Despite the obvious fact that electricity has to come from somewhere and the batteries are environmentally disastrous to make, electric bikes are more than likely the future. TT Zero is probably quite a few years ahead of its time and will become relevant one day, but at the moment really it is a joke. The Mugens are beautifully made engineering marvels, but there is NO ONE ELSE! The 250 class was scrapped because there were supposedly not enough entries and they were seen as becoming out of date but at least there was an actual race. Are the organisers embarrassed or delighted with the Zero's, I don't know. From a massive fan of actual racing on the mountain course though, they are indeed Zero interest.
