LOL that front derailleur wire....
mmmm some creative cabling going on. ( see rear brake pic on e-bay)
Pretty sure we are looking at an Sofrider V1 upgraded to 16 speed.
If you look at the rear swing arm I am pretty sure that is a fatter triangled Sofrider Ver 1 frame.
+ no cable stop on the boom, cant see if there is a pulley mount on the BB end.
V2 V1
I got a Cruzbike document "SofriderV2-DougBurton.pdf" on my HD that notes differences in wheel base, rear hub spacing, seat height, and down tube shape.
