Maybe Dahon is capitalizing on the Dove name like how modern BMW/Mini cars are actually often large cars. Years back I had a purple SRA683 but it was called a Mantis back then because it sorta looks like a praying mantis. I recall the second top tube at the frame joint seemed to add rigidity. I thought it was a great bike but I had a superior handling Silvertip and smaller BYA Dove so the middle size Mantis had to go. I almost did an endo from dropping into a rain grating but no damage to the strong rims; narrow tires are deathtraps on public streets IMO.
