Re: A Snow Bike
looks like i'm not the only one with that snowmobile idea. I can't afford the $500 and 27lbs it adds to the bike. I'm trying to make my own. so far my idea goes like this. take two old mountain bike tires and cut them so you can stitch them together. cut out the metal rim in the tires that give them the stiff circular shape. that will be the actual track. Then i'm gonna use a bicycle hub i found at the dump as an idler pulley. It will trail maybe 18inches behing my back tire, mounted with two steel tubes i hacked off an old snowblower. I figured and bump would snap whatever i use to connect the tubes to the frame with. So i'll have them on some kind of a pivot(probably utilizing the rear axle) and rig up this rear shock i pulled off a cheap mountian bike that i found at the dump. the track will wrap around my normal tire and the bicycle hub. what do you think?
