There is a growing selection of bike cargo trailers available to cyclists. However, bike cargo trailers are still a niche/specialty product. Because of this, their price is relatively high as compared to the majority of bicycles sold. A new bicycle trailer will cost between $200 and $400. For someone who is poor, on a budget, or just not interested in spending very much on bicycling equipment, $200+ is cost prohibitive.
Bike cargo trailers are a great enabling force for bicyclists. Many bicyclists discover that they hardly use a car anymore once they have discovered all the loads they can transport by bike trailer. For bicyclists with less money to spend, the advantage of being able to get oneself and all of one’s stuff around by bicycle is even more greatly appreciated.
