How to Install Motorized Bike Rear Sprocket Assembly on 26" Wheel
Important Update: The sprocket adapter has been redesigned and you have the most updated version. It will only come with 1 set of metal plates. The metal plates will make a complete circle. This goes on the inside of your hub and will bolt directly to your sprocket. The rubber grommets will go in between your spokes/metal plates and your spokes/rear sprocket. You should have everything you need.
When tightening the sprocket adapter onto the wheel. Please tighten in a Crisscross pattern to ensure the unit is evenly tightened.
