I'm interested in exploring the possibility of modifying the scooter for additional functionality. Specifically, I'd like to know if it can be adjusted to accommodate cargo or a second passenger. This feature is crucial for my intended use, as it would significantly enhance the scooter's versatility and usability. Additionally, if modifications are feasible, I would appreciate details on the process involved, any potential impact on the scooter's performance, and the associated costs. Understanding these aspects will help me make an informed decision and determine if this scooter aligns with my requirements for transporting goods or passengers. Looking forward to your insights!
