I had my bike on the trailer last weekend. I went for a little ride just to get used to trailering and backing up and such. The one thing I noticed is that the trailer makes a lot of noise. Whenever I hit a bump because the hitch fits kind of loose it makes a knocking noise. Anything I could do about this? I'm sure it won't hurt anything but the noise is scary! I was going to perhaps wrap some electrical tape around it before installing the hitch to see if this would help.
