Nijland (of course a Dutch company) makes a number of interesting cargo bikes. None are made specifically to transport children, but with the Dutch being how they are, I am sure kids get thrown in there with the cargo from time-to-time. The Nijland delivery tricycle can haul an impressive 300kg of load! The wheels are 26″ and the tubing steel, as you might expect for this sort of use. It is essentially a hard wood platform that you can load anything on. It has a classic dutch look and seems sturdy as…well a dutch bike.Of course, we would not suggest carrying children in here with no seat belts or cushions, but it is a very beautiful bike with a solid mahogany box. It sells for about 3,500 Euros (including VAT), so it is not for those that do not really have a good business use for one, such as hauling a heavy load, delivery, or promotion–even house moving in the Netherlands. Also, don’t even think about this if you plan to conquer a hill! Surprisingly, the standard configuration seems to be a single-speed fixed gear, but an 8-speed hub is available as an option. It is mainly a European style bike, but a number of dealers are said to carry the Nijland in the United States. It is reportedly in use in Battery Park City in New York–which just goes to show that bike culture really is coming to New York City.
