On pages 38 and 39 of the April 2011 issue of Motorcycle Consumer News is an article by Glynn Kerr, a prominent motorcycle industrial stylist, discussing the design of most of the current production electric motorcycles. He seems to prefer the design of the MotoCzysz, followed by the Mission R and the Brammo Empulse.
Regarding the Brammo products he says:
"Purposeful Brammo Empulse features its high-tech battery compartment".
Also mentioned are the Brammo Enertia which: "suffered from its heavy, flat-sided bodywork".
Just keep in mind that this fellow is a consultant who is paid to design new motorcycle models for major manufacturers, so your opinion may differ from his.
