The following is a copy and paste from a Rakuten product page: This is a front-mounted child seat for bicycles that can be easily attached and removed without tools. It is applicable to city family cycles, folding bikes, and small-wheeled bikes (minivelos). Safe and Comfortable: The material is aviation aluminum alloy and has obtained American safety certification. The soft cover handle and the front-insert pedals (footrests) are also direction adjustable. Holes and grooves are designed in the seat to allow air to flow. The optimal riding posture can be adjusted according to the child's physique. Safe and comfortable design. Foldable: Easy to fold, lightweight (approx. 1KG), and comes with a free carrying packing bag. Applicable for children aged 2 years and older, under 125cm tall, and weighing less than 30Kg. I have used it for several years without any problems. It was very convenient. It can still be used. Please use it in parks, such as during picnics. I think it should be avoided on public roads for safety reasons. Use at your own risk. Shipped in simple packaging with recycled materials. Please do not purchase if you are sensitive to this.
