Model +30 was originally developed for the Swedish market only in 1995, but today it is exported throughout the world. It is based on the same construction as Model Light, but it has a 30 cm longer box. This model is particularly suitable for transporting up to six children by fitting six tip-up seats in the box. It is possible to mount three tip-up seats on each side of the box and still have plenty of room. Model +30 can also be mounted with either one or two benches or seats – one bench or seat in each end of the box. The box is a straight box – meaning it has a 50-cm box height all around. The size of the box has a volume of 366 liters and a max payload of 100 kg making it also a useful cargo bike for carrying bulky sizes of material and/or a lot of goods.
