Mezzo ori are completely different frame design from a brommie. Mezzo is worth looking at if you want to customise a folder. It lends itself to fast road bike. See the mezzo and upgading an ori threads. I built a very upgraded 27 speed mezzo with a road race set up for less than a grand in uk. I will not be able to get rhe same bang for my buck with my brommie.
I can go out and easilt pick up a cheap mezzo ,if yoy want a high preformance compact then its ats easier and cheaper route.
