Polo bike geometry + addons

Me, but you need to convine:

• bb height with the smaller wheels (not to low)
  
• pedal overlap with big ones (longer wheelbase)
  
  

Anyway, 26x2.2 it's almost the same diameter than 700x28c. The hard thing is to convine diferent tire sizes, like 26x1.5 with 700x40c.

And last thing, brakes; you can put to v-brake mounts, or just one for 26" and caliper brake for 700c (like some old MTB).
