Urban Roller / Bike Trailer

More and more people ride bicycles because the activity benefits the user’s health, and helps save the environment. It also provides a convenient way for commuting in the city, if bicycling commuters carry their bags with trailers. The Urban Roller can be used both attached to a bicycle as a trailer, and free-wheeling, as a hand-pulled cart. Without weighing themselves down, urban commuters can roll the trailer wherever they want, for any suitable purpose.
