I disagree that it’s just drunk people, have a look on stolen bikes in Cambridge on Facebook you can even find out the names of the criminals and still nothing is done by the plod.
There appears to be a mix of bikes being stolen as a job and bikes being stolen to feed a drug habit.
I agree in terms of what to buy just something crap and a couple of d locks, never ever park in the train station parking they just unscrew the bike racks. Even town centre bike racks are a no go as they can just pretend they are unlocking.
They have those voi bikes that I guess are opened with an app?
