Align your expectations
It is a good idea to agree in advance on what sort of trip you want.
Some cyclists may want to ride at a leisurely pace, stop here and there to take photographs or look at flowers while others prefer to clock up the kilometres on their bicycle app.
Have a chat about it before you set off. Base your journey on the fact that on average adults cycle at approx. 15 km/h and children at 8 km/h.
