For Business and personal use, Yellow Jersey will provide you with comprehensive insurance cover for your dutchbike, cargobike or Ecargobike. Give them a try, we have had good service from them so far, if you find different, please let us know.
Why do you need specialist bicycle insurance? The simple answer is that business insurance for riders can be tricky and that home insurance cover is likely to be inadequate for a cargobike/Ecargobike.
Their Bicycle Insurance covers your equipment when riding, offers security marking, vandalism and accidental damage cover, dental treatment and new for old bike replacement cover. For more adventurous or the racier riders, training or racing worldwide is covered.
