Yes, you can add both a front and rear child seat. The rear will require a Heavy Duty Rear Rack due to the new bike design. 

Front child seat

Because the VanMoof handlebar design differs from most other bikes, the Thule Yepp Nexxt Mini and Thule Yepp Mini are the only front child seats that fit the VanMoof S5 & A5. You can buy the Thule Yepp Nexxt Mini on our Accessories website page and in VanMoof Stores. For both the S5 & A5, it's advised to assemble the Thule Yepp Nexxt Mini without using the C-clips.

Rear child seat

This will be available soon, so keep an eye on the newsletter to receive updates on accessories.
