Don't have a regular stem but a so-called A-head system, and is using a front-mounted child seat difficult? Yepp has a solution: the Ahead adapter. This easily attachable adapter allows you to mount a Yepp Mini seat to bikes fitted with an A-head stem. This way, you can enjoy many carefree miles together with your child. If you use the Yepp Ahead adapter, it's not possible to fit a Yepp windscreen.
