Few mods/accs (DIY) in my Sportsmen 16BH (LOT PICS!)

Nice mods, but as others pointed out, if you're supporting the bike rack with only u-bolts around the square bumper, the bumper will eventually crack and the bikes and rack will fall off. The bumpers are basically thin sheet metal that flex back and forth like a beer can. I installed a similar bike rack on my old trailer but had a welding buddy fabricate a receiver that mounted off the frame of the trailer.
