If you're looking at a trailer hitch type rack, fitting a tow bar to the Bolt might be problematic. You'll likely have to wait an take a peek under the rear, but it's likely that you would need to cut or modify the aero shield (if you can find a tow bar that fits).Can't you still install a bike rack even though the factory says not to tow a trailer or vehicle? Installation is going to be a problem too if the factory doesn't have a hitch as an option.
Cutting is definitely something I would need to take for someone else to do. I don't trust myself with a dremel and a cutting wheel.. it would end up ugly :|I looked under the back on my Bolt, and there is a whole bunch of room behind the rear facia for a aftermarket hitch to be installed, and the bolts that attach the rear aluminum "crash" bumper fasten to a couple of pretty beefy framelike pieces that should easily support a couple hundred pounds of extra weight. A hole would have to be cut for the receiver to come through, probably in the lower black part of the rear facia, below the aluminum "crash" bumper. If I were to guess, I would even say a class 2 hitch might be possible that way.
Still haven't installed it. Haven't had time.Someone received a hitch already for the Bolt way back in November. http://www.chevybolt.org/forum/121-towing/4618-trailer-hitch-2.html Pretty funny that bro1999 got his before it was supposed to be released officially.
