Regarding electric assist bicycles, installation may not be possible depending on the location of the battery. Installation may also not be possible on city bikes depending on the model. [Please check the class] This product is Class 27 (maximum load capacity 27 kg). Children who can ride in a child seat are those who have not yet reached the age of starting elementary school and weigh less than 24 kg. The maximum load capacity of the rear carrier includes the weight of the child seat itself. The weight of the child seat itself + the weight of the child should not exceed the maximum load capacity of the carrier. If the maximum applicable weight of the child seat itself is 24 kg, please use a Class 29 or higher carrier. Choose a rear carrier with a class suitable for your intended use.

Please refer to the images and be sure to check whether the SH dimension is suitable. This product has an SH dimension of 300~335.

If in doubt, please consult your retailer. * This product is mainly designed for everyday luggage transportation. Showa Industries rear carriers are manufactured using advanced design technology backed by a long history since its founding in 1927. Because high-quality materials are used, they are durable and can be used with peace of mind for a long time. In addition, Showa Industries' unique SH dimension allows you to select a rear carrier in a more optimal size, which was difficult to choose due to the different shapes of the frames.
