Looks like a neat trailer. In fact I think I may have seen one of them in a driveway in my neighborhood.
There is a thread on this forum called "Hitches for non-bicycle use" describing what other Bolt owners (including myself) are towing with their Bolts.
the manual ... just said not designed or intended. But it does have a towing section that says pleas load over the axle. So, even in the manual it shows that it can. Not designed or intended does not mean DO NOT or CAN NOT. Page 199 and 246 of the manual... 6. If your vehicle will...

I tow a boat with my Bolt and have found no problems thus far. I see that the SylvanSport Go weighs around 850 lbs, which I would guess is similar to or less than the weight of my boat & trailer. The main difference I note is that the SylvanGo Sport appears to have a fairly short wheelbase, while my boat trailer has an unusually long wheelbase for a small-boat trailer. I think a long wheel base will tow smoother than short, though honestly I'm not sure about that.
There's another thread here about installing a light controller for a trailer.
Given my experience pulling a boat, I would anticipate no problems pulling this trailer with your Bolt. Good luck!
