I've ridden the Big Dummy on packed snow trails this year with 26 x 2.0" XRs on it. It's a stable ride, but the back tire is lightly loaded for climbing slippery hills. I don't have the heart to ride all my bikes through the winter so it's going to be a Pugsley & Tikit winter while the Big Dummy rests until spring. I've stolen the Titec H-bars from the Big Dummy and used them on the Pugsley. I ordered another set of H-bars which will arrive in a week or two so at the moment the Big Dummy isn't even ready to roll.

I own a Bob trailer so I may break that bad boy out for any hauling needs I have this winter and use the Pugsley to tow it!

BTW - somebody has built your dream bike already....
