I passed a bike with some hacks the other day but was more surprised by what I did not see as what I did see. Here is the bike -
The handlebars are covered in masking tape and small flashlight is zip tied and taped to the handlebars.
If you look back up at the top picture you will notice however that the rear wheel is quick release and there is no lock of any kind associated with the back wheel. It would only take seconds for someone with ill intent to walk away with it. Seeing as this is NYC, I would have thought that security would be a high priority. It would take longer for someone to remove the light than the back wheel.
