Ebike high performance stuff is still in the development stage and most kits or parts you order do not come with documentation. The Cyclone is a great example of getting a Chinese made kit and good luck figuring out how to mount it to your bike. Its amazing Chinese manufacturers do not go the extra mile of paying someone a couple of hundred bucks to document how to install it…and whenever you do get documentation it is rare it is written by someone who is a good writer or who even English is their first language. This is kind of par for the ebike industry. Even the ultra refined bafang mid drives do not come with any kind of instruction sheet.
