New back wheel, chain, plus labor involved to put them both on shoddily (so I had to take it back to the shop after riding on it for two seconds): 96 Euros.
New lock because now apparently I need to lock BOTH the front and back tires: 12 Euros.
New clip on lights (because someone stole mine while it was chained outside the bike shop waiting repair: 15 Euros.
