The Yepp seats are made of that skinned foam stuff that Crocs made so popular and it’s ideal for a child seat because it’s soft and doesn’t absorb water. The Yepp also incorporates nice features such as a secure five point harness and quickly adjustable footrests. From 9 months old children are old enough to sit upright on the bicycle and love to be out on the bike. You can use a Yepp mini until your child is somewhere between 3 and 4 years old depending on how fast they grow. The Yepp mini is available in black and is compatible with our MT Crate child.
