Cargobike: proper carrying capacity on two wheels but don't expect to turn heads (at least not in a good way).
I don't know how much stuff 150 liters is but its a heck of a lot more than 99% of the two wheeled motorized vehicles on the road today, I'll tell you that much.
The Cargobike is butt ugly (bugly) but it would be nice to be able to stuff a week's worth of groceries into its, dare I say it, cavernous storage.
I won't be picking one up anytime soon but I can see Aprilia selling a whole mess of these for folks that need an inexpensive primary vehicle that can actually carry some gear. Just try not to be offended when people laugh at your bugly bike.
