During a demo day at EVC Heemskerk (18-08-2012) we took the opportunity to see how my old Vectrix compared to the Brammo on acceleration. It turned out that it was quite close. The Vectrix took a small lead in the first metres and kept the advantage.
The Brammo Enertia is a really fun bike to ride, and has great build quality.
But it deserves a bit more off the line power.

That thing is hideously ugly.
