I had set our trainer up with an old Schwinn World Traveler womens frame so several of us could use it but I hated it and the wife didn't use it anyways so I swapped it out with my sons Batavus Monte Carlo which is a bit short for me so I need a longer seat post.
I'd bring one of my bikes in but then my son couldn't use the trainer because mine are way too tall for him, I also need to find a bit more motivation to hit the trainer because it's just no where near as nice as a real ride outdoors.
One more here that won't ride in the winter, lots of people around here do but I just can't take that kind of cold. It was 7 degrees here this morning and January and February are when the real cold kicks in.
