Note: I haven't seen said video yet, but anyway....

40mph on the flats is basically the speed for a racing sprint. You'd have to be a very, very good athlete to hold that speed for more than 30 seconds on a bike with racing geometry & position, as the amount of drag is tremendous. Even 24mph is pretty fast for a commuting bike / commuter.

I'm sure the Tikit will ride about as fast as any other folder out there, though.
