Rent a half-wheeler or a tandem
A so-called half-wheeler - which is half a child's bicycle connected to an adult bicycle - is ideal for older children. The child is not just transported, but has to contribute to the pedalling.
A family tandem is also an option - and a fun way to cycle. It also means that you are always able to chat as you cycle along.
