I recently acquired a couple of Terra Trike Cruisers (the blue ones) and my son and I have been riding them around the neighborhood. When he is behind me, he says my rear tire really leans when I am turning. I put him on the bike and it does seem to lean a little, but he seems to think it is too much when I am on it. I have checked the wheel and it is tight and nothing seems out of the ordinary. It feels ok when I am riding it and I do not notice any weird sounds or feeling coning from the rear. Am I just over cautious and this is normal or is it something I should be concerned about? I assume it is normal. I am a big guy and I imagine I put some extra side load on the wheels when I turn, but would like someone else's confirmation of my thoughts.
