Blacks do over 50% of the crime in America despite being only 14% of the population

Doesn’t prove your point about why bikes are stolen. Seems statistically as likely that a white person might be responsible for a bike being stolen as any other group. So, I’ll lock my bike up in America regardless of the neighborhood demographics. 
Also think about it, if you get rid of blacks the statically over 50% of crime disappears and far-less bikes are stolen
Blacks invading Europe for the past decade resulted in high-crime and rapes
