yeah I was thinking of making a DIY roller chain track using the methods researched here
Tracked PEV. Tank tracks, treads. Anything in the PEV spirit with a shitload of traction, so many many wheels may count.
That would have either rounded or square tread pieces attached depending on the use case. For a single track board that could self balance diy ow style a rounded track profile would be required. I have been pondering the effect that more than one contact point on the ground will have on low-speed turning needed for off-road riding. To fix this I figured two tracks would be side by side and you have a virtual pivot with springs or bushings to give lean to steer input at 0 speed (segway style)
long story short this thing I want to build could also make it ok on snow I think although more tailored to gnarly hill climbing.
