In Holland, perhaps the country that is lauded as the most bicycle-obsessed city in the world, parents are encouraged to take their children on bike rides from as young as 6-9 months as long as they can hold their heads up by themselves. If your child can sit up unaided and their necks have fully developed, then they can embark on a bike ride.  However, it’s essential that they can do this and if you’re unsure consult your family GP to get their expert advice before embarking on a bike ride with your little one.
