It all happened so quickly.

Riding along at a tad over the posted speed limit. My immediate surroundings were quiet and luckily traffic free.
My frozen bottle of water popped out of it's holder and fell to the ground below me.

As my rear wheel hit the frozen bottle it got jammed between the tire and ground.

Reflexes caused me to stand up and move my weight forward.

After skidding for a couple of feet the wheel hopped over the bottle and traction was regained.

Riding a bicycle on the Greenway is hazardous
