I fell pretty bad this winter, and after that (even now without a trace of snow where I live) I feel the bike really slippery, mostly the front wheel. Riding on slightly uneven surfaces makes me feel I'm going to slide to the side, and side wind also feels I'm losing control of the bike.
Bike is less than a year old and I only commute with it, no long distances.
Could it be a technical problem or a confidence issue?
