Bikes are the best way for children to get around, since they can't drive. Children can ride their bikes to school, to a friend's place, to the shops or just up and down the street for some fun. However, to prevent accidents there are a lot of ways you can make bike riding safe for children.
PROPER SAFETY GEAR
Helmets, knee pads, elbow pads, whatever you can strap onto your child to keep them safe if they happen to fall off their bikes is a must. The helmet is a huge one. If they are wearing long sleeve clothing then the elbow pads and knee pads aren't really necessary.
TEACH YOUR CHILD ROAD SAFETY Go on bike rides with your children before you let them go riding the streets. Teach them about crossing the road and to wait for the green flashing person to appear first. Tell them they need to push their bike across the crossing instead of riding across, in case they fall off.
I know that no parent would just let their child ride their bikes in a foreign area. If your child knows your street well and how to get to school then you shouldn't have many worries about them getting lost.
STORE BAND-AIDS IN THEIR BAG Whenever my kids ride to school I also store 2-3 Bandaids in the front pocket of their school bags in case they have a minor injury.
