This trailer is based on the design of the well-known Carla Cargo trailer and will utilize Appropriate Technologies to ensure that it is both sustainable and environmentally friendly.
We recognizes the importance of promoting sustainable transportation solutions, especially in urban areas where traffic congestion and pollution are major problems. Bicycle trailers are an excellent solution for transporting goods by bike, and the Carla Cargo trailer is one of the most innovative and efficient designs on the market.
The project use materials and manufacturing processes that are environmentally friendly, low-cost, and easy to maintain.
We believe that this project will have a positive impact on our community and beyond, by promoting sustainable transportation options and reducing our carbon footprint.

This trailer is based on the design of the well-known Carla Cargo trailer and will utilize Appropriate Technologies to ensure that it is both sustainable and environmentally friendly. We recognizes the importance of promoting sustainable transportation solutions, especially in urban areas where traffic congestion and pollution are major problems. Bicycle trailers are an excellent solution for transporting goods by bike, and the Carla Cargo trailer is one of the most innovative and efficient designs on the market. The project use materials and manufacturing processes that are environmentally friendly, low-cost, and easy to maintain. We believe that this project will have a positive impact on our community and beyond, by promoting sustainable transportation options and reducing our carbon footprint.
