On all the untreated roads in the ice the trike (MTB Longstaff conversion) beats two wheels. Even with semi slick tyres I still keep going where my MTB slips over.
Three wheel skids are "interesting" but less chance of falling off, more like going under a bus.....
If the weather goes on like this I may put the nobblies back on, or even studs (or just go on the bus).
