Super handy seat for a little passenger in Urban Arrow. Can be locked (keys are included). Child sits low enough in the bakfiets to be safe but can look around easily. Individual harness provides total security. Child cannot unfasten him/herself. The seat can be installed on a regular bike. All parts are inluded as well as the manual. Was in use for about 1.5 years. Some minor scratches, however, the condition is still perfect.
