10:17 Brompton Electric vs T Line?
10:39 Electric T Line (You need a titanium fork)

Post Publication Analysis.
-There are low bar (flat) and mid bar options for both Urban and One
-Make sure you use a metal fork (ideally steel) if you plan adding an electric motor there. Carbon breaks instead of flex. http://www.bustedcarbon.com/
-I heard the hinge clamps self align. Finally!
-Carbon cranks is much more fragile than aluminium ones. You'll need to replace them more often if your cranks tend to hit the curb. For the sake ultralight money is due.
-It costs $5k USD of carbon and titanium parts to upgrade a steel brompton to reach 8 kg
-There are opportunities to make it lighter, for example change to titanium pedals, and carbon wheels.
