Good
review of EICMA 2012 by Michael Uhlarik, who is responsible both for the headlights used by the 2012-2013 Zeros and the Empulse, as well as the
Amarok P1 which hopefully will compete in TTXGP 2013.
Edit: No mention of electric bikes, but it's a good description of the lack of innovation of the incumbent gas bike industry. Brammo and Zero probably have 5x as many R&D engineers, proportionally, as Honda, Suzuki, et al.
Zero was not at EICMA this year, but Brammo was there and CRP unveiled the Energica.
