The only real safe way to carry your child on a bike is on a rear mounted cycle carrier. We have both suspended child carriers and cycle carriers that mount directly to their included cycle racks for that extra strength and security. All come with padded seats and multi point harnesses to keep kids as safe as possible. The general upper weight limit of our child seats is around 40lbs/18kg/3.2St but please note, every model differs. Tip: ALWAYS have your child wear a helmet with a cycle carrier.
