Travelling with Silvio
What is the smallest size box that the Silvio 2 will fit in without too much dismantling?
How long is the wheelbase?
It depends on what you consider "not too much dismantling". I have used travel cases which involved just removal of the wheels, pedals and stem/handlebar. There are more frame components on a Silvio than a standard DF, but there should be no reason that doing a similar amount of disassembly plus disconnection of the front triangle, you couldn't fit it all in one nice package.
