Steering rod does not disturb driving, the tube does not hit knees. The steering is stable. Hitting stones with the front wheel does not change the direction. But there MUST be a steering damper to make fast driving stable. Front wheel drive is better in winter than back wheel drive.
Front wheel driven trike goes better through snow and turns better to the right direction.
Braking is effective and does not change the driving direction. There was much snow and ice in Finland in winter 1998 1999. The bicycle roads in Helsinki were often full of snow, and driving was impossible. I drove some day in temperature 23 C and had problems with wires and roll brake. I had to change the Litium grase to ordinary motor oil in the cables and Nexus roll brake.
