Physics being what they are, on a bicycle, with 60lbs in the trailer, attached to a 26lb bike with a 200 lb rider, you don't notice it other than at really slow speeds. The only time it's affected my handling was off road, very steep grade and hard braking it jack knifed me but any trailer could do that. Couldn't tell from your pics, did you do a single hitch to the bike or a double?
