In similar fashion to the majority of bicycles being reported stolen in Miami, this bike was locked with just a cable lock. We cannot stress how worthless cable locks are, if you really want to keep your bike please use a 16mm U-Lock. Only use a cable lock as a bonus, i.e to protect a wheel or accessories. It's impossible to prevent theft but you can at least make it difficult for thieves.
Protect your bike(s) against theft by using at the very least a 16mm U-Lock like the one pictured below.
