I purchased and assembled this, but it turned out to be too cumbersome for me to get my bicycles in and out, so I am selling it. I put it back in the original box immediately after assembly, so the condition is quite clean. There is also an instruction manual.

There are three sizes: S, M, and L. The S size is designed to store two bicycles, and the M size can store up to three bicycles. The L size has a wider space and can accommodate large motorcycles and seasonal items. By installing it in a corner of your garden or parking lot, you can easily organize your belongings daily and make better use of your outdoor space. Assembly is designed to be simple. No special tools are required, and you can install it smoothly by following the instructions. By installing it on a flat surface, you can expect more stable use, and even those who are not familiar with DIY can use it with confidence. There are also a variety of set contents to choose from, including a basic set, an "安心セット" (safe set) with a replacement cover, and the option to purchase the cover alone. Designed for outdoor use, the frame uses lightweight and easy-to-handle aluminum material. Nylon is used for the joints, allowing for sturdy assembly. The cover is made of polyethylene and is treated to reduce UV rays, so it is designed to withstand sunlight and rain. Replacement covers are also available, allowing you to use it for a long time and making maintenance smooth. It has a structure that can be used with confidence in an outdoor environment. The opening is zippered, allowing for smooth opening and closing, making it comfortable to put things in and take them out. The interior height is also sufficiently secured, so tall bicycles and tall luggage can be stored without difficulty.
