What should parents agree before allowing a child to ride?

Agreeing a few clear expectations up front makes riding safer and reduces misunderstandings later. Families often cover things like where riding is and isn't allowed, always wearing a helmet, no modified bikes, no passengers, no headphones, and sharing the route and expected return time.\n\nIt helps when these are agreed together rather than imposed, so the young rider feels part of the decision.
