WNTD: 56/57cm lock up bike, fun, in working order

Hello forum pals,

I would like a new lock up bike for the streets of london, what am i looking for you ask?

• 56/57 frame
  
• up to £400 for something which really stimulates the brain and hits everything
  
• working order
  
• takes at least a 32
  
• low maintenance
  
• no discs
  
• something with a bit of charm
  
  

i think these are the core requirements i would entertain

bonus points would be

• steel framed
  
• could be single speeded
  
• takes a 35 + guards or 38 no guards
  
  

alternative, wild card options

• i have some parts to make a fixed gear, a steel frame which takes 32/5s which has cranks and headset would be nice
  
• an old cross alloy cross bike with cantis, ugly, euro, one could flat bar
  
• retro mtb....maybe..........depends what it looks like
  
• something you think would fit the bill?
  
• to be honest i'd take another pompino in large if anyone has one.
  
  

ideally i can pick it up in london, after the 10th of July
