Honestly I would get back to cycling. How I would personaly come to this determination would be,
1. There is always risk of accident if it is walking down the street, driving down the street or riding a bicycle down the street. I was in a car accident with my 3 year old son a few years back and I continue to drive with him in the car.
2. I will be in better health because of cyclign so I will see my son grow up and marry have kids etc since I will live longer most likely.
3. It's great stress relief for me
4. It's soemthign I can enjoy with my son we go cycling together.
