I have only been riding 2 weeks and I was finishing my ride on Sunday and came around a corner to a sign that read "bump" as I was also approaching a stop light. As I went over the bump I hit grooved pavement. As I am downshifting as I approach the light my bike is being pushed to the side of the road. I let it go that way and pull into the gas station on the corner. At this light in every direction for about 2/10 of a mile is grooved pavement. I have no idea how to ride on it. I ended up "duck" walking my bike across the intersection and walking it back the way I came on the side of the road until I hit smooth pavement and then finished my ride home. I got on my bike again Tuesday for about 30 minutes and only stayed in my neighborhood. I know I can ride on the roads and need to get back out there but that experience shook me a little. I have thought about doing a ride in my car first as to where I want to go then riding it on my bike to be sure this doesn't happen again.
