When does a BSO start being a bike

[Andrew_P]

Anything under six thousand and lacking in Dura Ace or Super Record or SRAM Red.

A BSO is a bike that, when something small goes wrong, it's instantly not economically viable to repair.

 

[SatNavSaysStraightOn]

BSO = Anything that you can leave unlocked, outside on a busy street and know it won't be knicked in seconds/minutes/hours.

Editted to clarify

How do they change gear without any of these

You don't, you either park it in the hardest gear and grind it out or in the easiest one and spin spin spin, once a gear is selected it stays there for the rest of the bikes somewhat short lifespan!

 

[redcard]

A BSO is any bike heavier than your girlfriend.
