Motorized Winter Bicycle?
As much I would like to, I don't think I'll be able to ride a bike everywhere I want, when I want during the winter. I really don't want to pay for a car, so I'm looking into adding a small engine to a MTB so I have something to ride when conditions are too bad for a normal bike. I guess the main question is what will I need for tires? The main roads I use to get around are not plowed too well, though with a 26x2.3" front tire with screws added, I have managed without too much trouble. Adding a motor will definitely increase my speed, so I have a feeling I'll need to go wider to keep control of it. For pre-made studded tires, the Schwalbe Ice Spiker is 2.1" wide, which sounds too narrow. Any ideas for a wider tire I can add screws to for the winter? Any particular reason I should look for a 29'er over 26"? Should I be looking into getting a Surly Pugsley or a Salsa Mukluk?
And don't worry, I am setting up my Trek with studded tires and a disc brake so I do have a normal bicycle.
