Agreed. Going 40 mph on ice/packed snow in a car generally isn't a great idea. You will be surprised (hopefully not fatally) at how long stopping will take from that speed with compromised traction. Doing it on a bike/trike with zero protection is really not something I think you should aim for. Distance over time/stopping distances are substantially more than halved at 25mph.

Alright, how fast would you recommend?
I'm considering using 203mm disc brakes for overkill. Wise or no?
Also considering wide tires for better traction, I want to try not to die in the warmer months as well :P
Although I want to minimize losses to speed and range so maybe not.

I'd like to use a 29' rear wheel but I don't think it will fit on the kmx kit so I'll probably be using a 26' wheel.
i'm going to load that sucker up with as many batteries as will possibly fit under the seat, on the rack, and in the panniers.

What is your goal? Your brakes, in snow and ice, aren't going to be worth much. Your tires will be everything there. Your worse case scenario for brake load will be with clean sticky tires on pristine pavement after they have gotten hot. This isn't what you will be seeing in snow and ice.

Snow, ice and wet, is more about balance and modulation of the brakes with tires that set up for the surface. Raw braking power isn't as important in those conditions.

It will be interesting to see what you come up with.

As far as riding speed, you will figure that out very VERY quickly on your first trip.

I guess the end goal is to have a year-round rock solid reliable car replacement that can get me where I'm going reasonably fast without having to pay for gas and insurance.

You want weight on the front to ride slippery conditions. That is because yo can control the loss of traction much better on the rear than front. Racing on ice, we are on the handlebar for the entire race. In the snow we are playing a lot with fr and rr balance, but turns are always on the front.
Yup, the added weighted on my front DD and studded tire is my go to ice bike. Townie style flat foot frame and the seat even lowered a bit more is my favored winter bike.

What do you do on a mtb just after a snowfall when the roads have the compacted snow from all the vehicle tires, and your front tire just goes everywhere?

I have a studded tire on front.

Well, you have to dance the twist on your bike and trust your tire to regain traction once in a while. :wink:

High knobs mud tires are better, with spikes even better than studs, but those very difficult conditions that we have now are challenging any rider’s skills and confidence. Faster is making it better, if you have the balls.

Yeah I power fast and play the throttle game.

air pressure down doesnt help?

Im looking for a fat fork, should help lots with a fat tire up front dont you think?

Fat tires are floating, they are good on few conditions.

Chains are slow, and can make a costly mess of your bike when they rub or break.

We have to deal with the average. Unless one can have 2 or 3 bikes prepared for various conditions, best is to tune it for the most common state of the streets. I usually use two bikes, keeping my commuter for the most common wet/slushy salted pavement, and my dirt bike tuned for snow/ice.

I ride my front wheel, heavy MXUS DD, with studs on a flat foot frame. My feet are out runners.

Then put back the training wheels on your bike. :mrgreen:

I am keeping an eye for a fat fork that can fit my Townie, pretty sure I am gunna have to buy new.

It will be good in 2 ways.
The first, I can use the fat fork to install a rear dd motor with 2.1 tire in the front.
Second, use fat tire in winter where needed, like 10 days out of the year, though today with the big melt slide on the compact but crumbly stuff.
