I haven't ridden any distance, but like gamemaster, I was concerned about the seat shape.
I had the opportunity to take a GT for a spin. contrary to the look, the seat actually feels like the bulk of your butt is on it. I go 230, so I'm not slim.
That being said, there was a venture lite there. The steering seemed as lite and they were telling me it handles like a short track. That sled has a seat like a full dresser bike saddle on it and felt very comfy. While I wish there was a short track version of it, that may be the ticket for a trail cruiser for the wife.
