* longjohns are probably the most common type of cargo bikes
** they are described and discussed at the following pages: [https://en.wikipedia.org/wiki/Freight_bicycle#Long_John_bicycle en.wikipedia], [https://de.wikipedia.org/wiki/Long_John de.wikipedia], [http://www.longjohn.org/ longjohn.org]
** they tend to benefit from the following advantages: *** low center of gravity, *** good handling and moderate weight, *** moderate length and especially width, *** load is easily visible by rider, *** transmission is the same as for a normal bicycle** they may suffer from the following drawbacks: *** steering is achieved through a mechanism that adds complexity (and price) compared to cargo bikes types such as long tail, *** load size is somehow limited, *** load weight is limited compared to vehicles with 3 wheels or more (due to resistance and also to the lack of inherent stability)
