Building a bike for wet/snowy conditions...?

[haydenslides]

Wow, new to this forum and stoked!
I'm going to build a motorized bicycle with a Husqvarna 142 chainsaw engine.... I have a few questions!

I have a couple of requirements for this bike: #1: Needs to be able to work in wet conditions and snow. and #2: I still want to be able to pedal the bike.

So, my first question is how well does friction drive work with a tire slicked up with snow or water?
This is my only fear of using a friction drive setup. At this point I am unsure as to how I would attatch a roller to the clutch drum. Any suggestions? If i go this route, i'm thinking of using a urethane skateboard wheel with grit glued to it.

My second question is how would i set up a chain drive setup (possible even? )that would still allow me to pedal?

I'm going to be building this bike for accessing terrain for skiing that is on closed, gated roads...as far as snow riding goes it will be just having to cross patchy snow sections on gravel roads, not long sections of snow.

I'd greatly appreciate any info the gurus might have...

The guru you're looking for is on the bottom of page 5 in the pics. and videos sec. It is titled "Diy bikes in Wisco.
