A few issues with this
Firstly, electric bikes like disused concept art from an 80's sci-fi movie.
Secondly, what will spectators be treated to? There will be no thumping V twins, no screaming inline-4's, no open-pipe goodness... Just tyre roar and the whisper of an oversized Segway motor. Thrilling.
For a race like this, I'd expect the crowd to be wearing either anoraks and carrying clipboards, or wearing hemp and charging onto the track to save a squirrel from a rubber-based demise.
