Rather annoyingly the website spec http://www.mezzobikes.com/downloads.html quotes volume stats but not weight for the bike - so no way of telling if there are any weight advantages in picking the i4 or the d9. But the foldingsoc review linked to above suggests that the d9 at least comes in at slightly less weighty than an SP Brompton. As soon as I get a chance to pedal one around I'll post my thoughts.
