Depends on the bent. LWB tend to slide out more easily in front than
SWB or CLWB. The more vertical the steering axis, the more the ride
approximates DF. Generally speaking DF would be a bit more stable on
ice/snow than a 2 wheeled bent, but the lower seat heights would mitigate
the impact somewhat. Since speed is a bad idea, depending on snow
depths and ruts, a trike would be the bent dejure here.
