'decent' yes. But true, if you get a bike that's not full of electronics and motors and gps and what not, you dont have to spend a fortune. between 100 and 200 euro you ride a solid bike that does not fall apart with every bump in the road and can be repaired at home.

Hm, yes, 'lol'. That has not been my reaction when I found my bike missing.

In rural Sweden - where I now live - they're free when you find them in the ditch, notify the police about your find with identifying data like frame number etc and wait for 3 months. Assuming that the bike does not have a label identifying the owner - in which case you should contact him/her - they'll send you a letter confirming you're now the owner. Those bikes often need some work - how does a 30-speed MTB end up chainless in a ditch in the middle of nowhere? - but that is all part of the 'game'. It is hard to get closer to re-use, reduce, re-cycle than cycling on re-used bikes.
