This is a 36V, 350W front hub motor conversion kit for 16-inch wheels, purchased from the SOMEDAY official store. It is new and unused. As shown in the images, everything you need is included. Includes: * KT Controller * KT-LCD8H color LCD display (Image 4) Operates with a pedal rotation sensor. Front fork hub width: 100mm. *Battery sold separately.* Images 5 and later are from the purchase description, so please refer to them. There may be differences from the actual product. Personally, I was planning to adjust the output to the equivalent of 250W and set the pedal assist to a maximum of 24 km/h, using it as an electric assist bicycle. I don't think more power is necessary, as it would no longer be considered an electric assist. Regarding the LCD display, the product is the "KT-LCD8H color LCD display" shown in image 4, which is more advanced. It is not the black and white LCD3 shown in images 5 and later. I bought this intending to install it, but I don't have time to assemble it, so I am selling it. At the time of purchase, the shipping cost from China was around 10,000 yen, but I am selling it at a lower price. This is a rare kit for 16-inch wheels, so how about building the fastest small-wheeled bicycle? Although it's for 16-inch wheels, the settings can be changed, so those who can rebuild wheels can also change to a different wheel size. Thank you. I am also selling other items, so please take a look.
