Yes, I built the snowbike out of need to ride during the long New York winter, it took about 2 months,1 snowmobile,1 honda 550 , tube ,and a welder to do. No machined parts.
The winter before I wanted to ride but the shop is only so big and it's all left hand turns.
The day on youtube was first start up, shakedown and weld check, it was 10 below that day, a real eye opener even with a suit. This is the pond in front of my house, it's almost 2 miles long and plenty far enough at -10.
I was going for a chopper type stance but had to be reasonable in order to steer, and not to wash out or flip over. As you can see , it's hard to flip over, even when attempting a moving 360, takes 2 riders with ease.
Yes there are things I would do differently on the next one, I could only get this one up to 55+. the goal for the next one would be lower,4 ski steering, and 2 tracks, less wind on the body and 100mph, or more with a chute. It's less than 2 miles on ice.
One thing I found out, a man with a welder and wrenches will never have to walk. And it's easy to make your friends and neighbors say" what the hell is he doing now?!!"
